The southwest of Australia has been named as one of 25”hot spots” for future species extinction(滅絕)because of global warming.A new study says global warming will become a top cause of extinction across the world,with thousands of species of plantsand animals likely to be wiped out in the coming decades.
According to the study,global warming ranks among the most serious threats to the planet’s biodiversity and,under some conditions,may be more than that due to deforestation.This study provides even stronger scientific evidence that global warming will result in catastrophic(災(zāi)難性的)species losses across the planet.Last month,a UN study said humans were responsible for the worst extinction and urged extra efforts to reach a UN target of slowing the rate of losses by 2010.
Scientists disagree about how far global warming is to blame compared with other human threats such as deforestation,pollution and the introduction of some species to new habitats.But the new study looks at the 25 “hot spots”—?areas? that contain a big concentration of plants and animals—and predicts that 11.6 percent of all species,with a range from 1 to 43 percent,could be driven to extinction if levels of heat trapping gases in the atmosphere were to keep rising in the next 100 years.
The range would mean the loss of thousands of species.The study gave a wide range because of uncertainties, for instance, about the ability of animals or plants to move towards the poles if the climate warmed. Rare plants,tortoises or birds found only on the southern tip of Africa cannot move south because the nearest land is thousands of miles away in Antarctica.
小題1:According to the passage,which of the following about Australia is TRUE?
A．Australia possesses the richest species in the world.
B．Australia is the country with the highest rate of extinction.
C．The species in the southwest of Australia will be easily affected by global warming.

小題2:According to the passage,all the 25”hot spots”-------- .
A．a(chǎn)re rich in plants and animals
B．a(chǎn)re lacking in natural resources
C．lost most of their plants in 2010
D．will be much hotter than the rest of the world
小題3:We can infer if the climate warms,the animals in Australia will most probably move to the ______ .
A．northB．eastC．westD．south
小題4:What would be the best title for the passage?
A．Australia Named as Extinction”Hot Spot”
B．Global Warming and Species Extinction

Christmas Eve means a warm get-together with friends, a candlelight dinner, or perhaps a celebration at a pub for students. But, for Cai Yingjie, the night has a different meaning: helping beggars（乞丐）and the homeless(people without homes).
Cai, who is a student in journalism at Tsinghua, could be found at Beijing’s Wudaokou Light Railway Station that special evening. When she saw an old beggar, she took the cold, rough hands of the woman with her warm, clean hands, and gave the woman some warm bread and helped her put on a pair of new gloves.
The woman was surprised for a few seconds, then burst into tears, saying “for the first time I feel respected”.
Cai said, “A beggar’s life is very hard. That’s why I want to help them.”
Cai was one of 14 Tsinghua students spending Christmas Eve among the poor. They walked in the cold wind along the streets from 4 to 7 pm on Friday, visiting 15 beggars in Beijing’s Haidian District.
They brought bread and gloves with them, and stopped to greet beggars and offer them some of the warm food. Each beggar greeted them with a look of surprise.
“I know the activity can’t help much, but it’s meant to show our respect and care for beggars and the homeless who have been neglected for so long,” said Sun, head of the group. “And Christmas is a good time for that.”
小題1:What does Christmas Eve mean to the 14 Tsinghua students?
A．Taking 15 beggars to Tsinghua.
B．Getting together with friends.
C．Showing care to the beggars and the homeless.
D．Selling bread and gloves to the beggars.
小題2:What does the beggar mean by saying “for the first time I feel respected”?
A．The beggar has been waiting for Cai for long.

The evidence for harmony(和諧) may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image （形象）of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it had ever been in the past.“We were surprised by just how positive(肯定的) today’s young people seem to be about their families,” said one number of the research team.“They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds：they want a car and material goods，and they worry about whether school is serving them well. There’s more negotiation(商議) and discussion between parents and children，and children expect to take part in the family decision-making process. They don’t want to rock the boat(搗亂).”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel Lazall. “I always tell them when I‘m going out clubbing. As long as they know what I’m doing， they’re fine with me.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years， there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments(評論),“Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over. ”
小題1:What is the popular images of the teenager today？
A．They worry about school.
B．They dislike living with their parents.
C．They have to be locked in to avoid troubles.
D．They quarrel a lot with other family members.
小題2:The study shows that teenagers don’t want to __________.
A．share family responsibility
B．cause trouble in their families
C．go boating with their family
D．make family decisions
小題3:Compared with parents of 30 years ago, today’s parents ____________.
A．go to clubs more often with their children
B．a(chǎn)re much stricter with their children
C．care less about their children’s life
D．give their children more freedom
小題4:According to the writer, teenage rebellion __________.
A．may be a false belief
B．is common nowadays
C．existed only in the 1960s
D．resulted from changes in families
小題5:What is the passage mainly about？
A．Negotiation in family.
B．Education in family.
C．Harmony in family.
D．Teenage trouble in family.

B．Preparing for a Hurricane
C. How Hurricanes Move
D. How Hurricanes start
E. Hurricane Names
F. Hurricane Damage
Hurricanes
Hurricanes are gigantic tropical storms that can be hundreds of kilometers wide. They bring along very strong winds and a lot of rainfall. They often cause flooding near the coasts and sea levels rise.
1. __________________________
Hurricanes are born over tropical oceans, usually during late summer and early autumn. They need two things to get them started: heat and moist air. During the summer the ocean surface heats up and warm moist air starts to rise. Cool air sinks down to replace it. This creates an area of low pressure. The rotation of the earth creates winds around the center of such a low-pressure area. In the northern hemisphere the air moves counter clockwise, in the southern part clockwise. Such a system is called a cyclone. When warm air rises, it cools and creates clouds. Soon, thunderstorms form and it starts to rain.
All hurricanes begin as cyclones but not all cyclones become storms or hurricanes. Some die out a few days after they start. They don’t have enough energy to become a hurricane. When winds are stronger than 119 km an hour a storm officially becomes a hurricane.
2. __________________________
The center of a hurricane is called the eye, a calm area with little rainfall. It is about 30 to 50 km wide. Inside the eye the sea can rise up to one meter because the air moves up. The eye wall is around the eye. This is an area of thunderstorms, rain and the strongest winds—up to 300 km an hour. Then come long bands of rain clouds that are curved towards the center of the hurricane.
3. __________________________
In the northern hemisphere hurricanes normally move in a westward direction and then they turn north and northeast. Their path takes them away from the warm tropical water of the equator. When hurricanes move over colder water or over land they lose a lot of their energy. They slow down and as time goes on, they disappear. In the southern hemisphere their path leads them to the south and southeast.
4. __________________________
When a tropical storm forms over the Caribbean Sea it gets a name. Every year the first storm of the season is given a name that starts with the letter A, the second storm gets a name starting with B and so on. Years ago only women’ s names were used for tropical storms. Today male and female names alternate –for example, the first storm is named Alexandra, the second one Billy, then Catherine etc. Each year new names are used so that you can connect a storm to a certain year.
5. __________________________
Hurricanes are causing more and more damage throughout the Gulf Region, mainly because the population is constantly growing. Many things can be done to protect yourself and your property during a hurricane: Keep emergency supplies of food and water; keep a battery-powered radio ready in case the power goes out. Listen to the instructions you get; keep the gas tank of your car full, in case you have to leave quickly; protect your house by nailing plywood over the windows and doors. Tie down loose objects; find out which roads are best to take you away from the storm; leave your house as soon as you are ordered to evacuate, etc.

The UK has a well­respected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all, sometimes it can be confusing．
October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life．
However, having just left the comfort of home and all your friends behind, the prospect（前景）of meeting lots of strangers in big halls can be nerve­wracking（令人頭痛的）. Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
Here is some top advice from past students on how to survive Freshers’ Week：
●Learn rules. Make sure you know British social etiquette（禮節(jié)）. Have a few wine glasses and snacks handy for your housemates and friends.
●Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.
●Be sociable. The more active you are, the more likely you’ll be to meet new people than if you’re someone who never leaves their room.
●Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.
So with a bit of clever planning and effort, Freshers’ Week can give you a great start to your university life and soon you’ll be passing on your experience to next year’s new recruits．
小題1:Which of the following statements is FALSE according to the passage？
A．October is generally the busiest month for universities．

For high school leavers starting out in the working world, it is very important to learn particular skills and practice how to behave in an interview or how to find all internship(實(shí)習(xí)). In some countries, schools have programs to help students onto the path to work. In the Unites States, however, such programs are still few and far between.
Research shows that if high schools provide career-related courses, students are likely to get higher earnings in later years. The students are more likely to stay in school, graduate and go on to higher education.
In Germany, students as young as 13 and 14 are expected to do internships. German companies work with schools to make sure that young people get the education they need for future employment.
But in America, education reform programs focus on how well students do in exams instead of bringing them into contact with the working world. Harvard Education school professor Robert Schwartz has criticized education reformers for trying to place all graduates directly on the four-year college track. Schwartz argued that this approach leaves the country’s most vulnerable(易受影響的)kids with no jobs and no skills.
Schwartz believed that the best career programs encourage kids to go for higher education while also teaching them valuable practical skills at high school. James Madison High School in New York, for example, encourages students to choose classes on career-based courses. The school then helps them gain on-the-job experience in those fields while they’re still at high school.
However, even for teens whose schools encourage them to connect with work, the job market is daunting. In the US, unemployment rates for 16-to 19-year-olds are above 20 percent for the third summer in a row.
“The risk is that if teenagers miss out on the Summer job experience, they become part of this generation of teens who had trouble in landing a job,”said Michael, a researcher in the US.
小題1:According to Robert Schwartz，_________.
A．there is no need for kids to go for higher education in the US
B．students should get contact with the working world at high school
C．education reform should focus on students’performance in exams
D．teenagers in the US can’t miss out on the summer job experience
小題2:What’s the main idea of the text?
A．Arguments about recent US education reform.
B．Tips on finding jobs for high school leavers.
C．The lack of career-based courses in US high schools.
D．Advice for American high school leavers.
小題3:The underlined word “daunting” in Paragraph 5 most probably means___________.
A．discouragingB．interestingC．creativeD．unbearable

Mars Was Not Always Bitterly Cold
Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today.  The Caltech scientists say they have directly established the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented.
The Caltech scientists say carbonate（碳酸鹽） minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite（隕石） that had its beginnings near the Martian surface.
Today, the average temperature on Mars is sixty-three degrees below zero Celsius.
The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have confirmed the information.
Caltech Geology Professor John Eiler was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information. It shows that early in the planet's history, at least part of Mars could support a climate like that of Earth.
The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars' surface when another space rock struck its "home."
小題1: The underlined word “establish” in Paragraph 1 probably means “___________”.
A．to set up
B．to make people accept a belief
C．to discover or prove
D．to start having a relationship with others
小題2:How did the scientists reach the finding?
A．By studying Allan Hills meteorite.
B．By using spacecraft orbiting Mars.
C．By studying minerals gathered on Mars
D．By studying a meteorite on the Martian surface.
小題3:According to the fourth paragraph, what have spacecraft orbiting Mars done?
A．Measuring the temperature of Mars.
B．Taking photos of the surface of Mars.
C．Confirming that there is water flowing on Mars.
D．Finding where human beings will probably land on Mars.
小題4:How did Allan Hills meteorite get its name?
A．From its original place on Mars.
B．From where it was found on the earth.
C．From the name of the scientist who found it.
D．From the name of the aircraft that discovered it
小題5: Where can we most probably read this passage?
A．In a biography of scientists.
B．In a geography magazine.
C．In an environment report.
D．In a science report.
