Now satellites are helping to forecast（預(yù)報(bào)）the weather.  They are in space, and they can reach any part of the world.  The satellites take pictures of the atmosphere（大氣）, because this is where the weather forms（形成）.  They send these pictures to the weather stations.  So meteorologists（氣象學(xué)家）can see the weather of any part of the world.  From the pictures, the scientists can often say how the weather will change.　　 Today, nearly five hundred weather stations in sixty countries receive satellite pictures.  When they receive new pictures, the meteorologists compare（比較）them with earlier ones.  Perhaps they may find that the clouds have changed during the last few hours.  This may mean that the weather on the ground may soon change, too.  In their next weather forecast, the meteorologists can say this.
　 So the weather satellites are a great help to the meteorologists.  Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours.  Now they can make good forecasts for three or five days.  Soon, perhaps, they may be able to forecast the weather for a week or more ahead（提前）.

Your daughter has finally reached the age of 18, and you think perhaps your job will finally get a little easier. That could be wrong thinking - as the parent of any 18-year-old will tell you.  Learning to cope with an ungrateful 18-year-old daughter takes patience, understanding and time.
_______ When she was a little girl, she wanted you to be involved（參和） in everything of her life from her daily activities to her friends. This is' no longer the case. She's a grown woman who needs her own personal life. Comment（評(píng)論） on her choices only when asked to do so - especially if you want to say no to her.
Allow her to make mistakes. No parent wants to see his or her child fall, but the days of protecting her all the time are at an end. Unless（除非） you see a train coming, let her fall when she makes poor choices. It will enable her to grow past the ungrateful "know it all" stage.
Encourage dialogue whenever you can, rather than planning talks. She's more likely to open up to you when talking over something trivial (瑣碎的). Anytime she wants to talk, become a willing listener in the conversation. You never know when a deeper, more important conversation will develop.
小題1:What does the underlined phrase "cope with" mean?
A．walk withB．go withC．talk withD．deal with
小題2:Which sentence is best to put into the blank in the second paragraph?
A．Never give your opinions to her.
B．Give her the space she asks for.
C．Never take part in her activities.
D．Always say yes to her.

B．sometimes make mistakes
C．should let their children fall as often as possible
D．shouldn't allow their children to take the train alone

A．daughtersB．studentsC．parentsD．females

When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight off enemies.
Over millions of years, plants have developed their own defense system (防衛(wèi)系統(tǒng)). Chemicals are fantastically used by plants to survive (幸存). By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.
One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount (數(shù)量) of poison increases in the other leaves. “It’s like the injured leaves telephoning the others to fight together against the enemy,” he said.
The tree also sends defense messages to neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, he will die.
Every kind of plant or tree is good at producing a special set of chemicals. Herbivores, like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor.
In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest.
小題1:From the first 2 paragraphs, we can learn that _________.
A．plants can do nothing against their enemies
B．chemicals are quite useful for plants to survive
C．a(chǎn)n antelope can always run away from a strong lion
D．leaves, roots, flowers and fruits of plants are poisonous
小題2:If animals eat one Golden Wattle tree’s leaves, the tree can________.
A．kill the animals with a special smell
B．tell other trees to come to protect it
C．warn other trees against the animals on the phone
D．send defense messages to the neighboring plants
小題3:The underlined word “herbivores” in the 5th paragraph probably means animals which _____.
A．produce poisonB．live on small animals
C．like to eat rabbitsD．feed on plants or grass
小題4:The last paragraph of the passage suggests that this kind of defense system is ________.
A．bad for animals B．good for forests
C．helpful to some animalsD．harmful to forests
小題5:The passage is mainly about __________.
A．the examples of protecting forests
B．the balance between animals and plants
C．the ways of plants fighting against enemies
D．the relationship between lions and antelopes
