Soon computers and other machines will be able to remember you by looking at your eyes! The programme works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition(眼睛識別) programme is already being tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon, this technology will take the place of all other ways of finding out who people are.
However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the programme can be up to 94% correct, depending on(依靠) how good the technology is. Some programmes may only be right 51% of the time. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.
In the future your computure will be looking at you in the eye. So smile!
小題1: How does the eye-recognition programme work?
A．You write your number.B．You show your ID card.
C．You look at the machine.D．You say your name.
小題2: Why can the programme be up to 94% correct?
A．Because eyes never change.

Reading is a good habit, but the problem is there’s too much to read these days and too little time to read every word of it. There are hundreds of skills to help you read more in less time. Here are two skills that I think are especially good.
Preview — if it’s long and hard. Previewing is especially useful for getting a general idea of heavy reading like long magazine articles and business reports.
Here’s how to preview.
Read the first two paragraphs and the last two paragraphs carefully.
Then read only the first sentence of the other paragraphs.
Previewing doesn’t give you all the details. It keeps you from spending time on things you don’t really want － or need － or read.
Skim － if it’s short and simple. Skimming is a good way to get a general idea of light reading like popular magazines or the sports and entertainment of your daily paper.
Here’s how to skim.
Get your eyes to move fast. Sweep them across each line.
Pick up only a few key words in each line.
Everybody skims differently. You and I may not pick up the same words when we skim the same piece, but we’ll get a similar idea of what it’s all about.
小題1: How many skills does the writer introduce to help us in reading?
A．One.B．Two.C．Three.D．Four.
小題2: What should you do if you read a long article according to the writer?
A．Read every word of it.B．Read all the details.
C．Pick up a few key words in each line.
D．Read the first and the last two paragraphs carefully.
小題3: If you read a simple article, which reading skill is better to get the general idea?
A．Previewing.B．Skimming.C．Reading.D．Sweeping.

Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such as Star Wars (星球大戰(zhàn)) . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made “brain”. Leading the robot revolution （革命）are industrial(企業(yè)) robots that work in factories. Industrial（工業(yè)） robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren’t as friendly and bright as those you saw in  Star Wars. But, their makers say, today’s home robots “walk”, sense objects(感知物體) in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect.
We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths（波長） of light, and hear certain sounds. That’s because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can’t. To understand what their sensing devices(傳感器) pick up is a hard job. Remember, man—made brains handle(處理)information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like—using only zeroes and ones.
小題1: From the passage, we can see that factory robots _________.
A．help to improve other types of robots
B．a(chǎn)re most active in industrial revolution
C．a(chǎn)re playing a more important role than other types of robots
D．a(chǎn)re the tallest type among robots
小題2: It seems that home robots are __________________.
A．more widely used than factory robots
B．less common than factory robots
C．capable of doing any kind of housework
D．free from making mistakes while performing(執(zhí)行) duties
小題3: Robots may deal with information that humans can’t. Which of the following is not one of the reasons?
A．They do not have so many limits as humans do.
B．They have man-made brains.
C．They may be equipped with a special kind of sensing device.
D．They handle information by using zeroes and ones.
小題4:The development of robots suggests that _________.
A．science and technology are developing fast
B．people are interested in new inventions
C．machines are more capable than humans
D．robots can be very interesting
小題5: According to this passage, present home robots ________.

Hip hop or rap (說唱) music started on the street and in the clubs of the New York City in the 1970s. People rap to express how they feel about their lives and problems.
Rapping in class.
Would you like to rap in class? Well, actually hip pop music is played in more than 10,000 schools in the USA. Why? There is a new school program called “Flocabulary” in which teachers use texts and hip hop CDs to help teach different school subjects. The words of the songs are just what students are studying. This makes learning easy and fun. Students and teachers are excited about the good results it has had on exam marks. Mr. Lee, a teacher in a high school, said, “I’ve used hip hop songs in class, and I have never seen my students so crazy about history! You can’t imagine how well they remember what I teach! We even try to write our own songs.”
Whose idea was Flocabulary?
Blake Harrison, a high school student, was the first person to come up with the idea of Flocabulary. The word “Flocabulary” comes from the word “flow” and “vocabulary”. “Flow” is a rap word for “style”, or the way a rapper says the words of a song. “Vocabulary” means the words you have to learn in a language. How did he get the idea? Well, he realized he could remember the words of a hip hop song very easily. So, why not make lessons into songs? Today together with Alex Rappaport, a song writer, Blake produces hip hop songs for math, science and literature (文學(xué)). They are now used in schools with great success.
小題1: Rap music started ______ in the New York City in the 1970s.

Is it a tree? Is it a bear? If you’re looking at a tree in the shape of a bear, it’s a topiary(林木雕塑). A topiary is a tree or a bush(灌木) that is trained into a shape. Growing a topiary garden takes both time and skills.
A topiary gardener should make a drawing first. The drawing shows the final shape that the gardener likes. The gardener then chooses a bush for the topiary. It may be one that just planted or one that is already in place.
In June of the plant’s first year, the gardener looks for new leaves. When the leaves grow, it’s time to shape(給……造型) the bottom of the bush. It needs about five years. The top is not trimmed during this time. In the fifth year, the bush grows tall enough for shaping. Then the gardener begins to shape the whole bush.
Once a topiary has been started, it needs care all year. In the summer it must be cut many times to keep its shape. This cutting also helps the bush grow. In the winter the bushes don’t grow. The gardeners have to brush snow of the plants, or snow may hurt some parts of them.
Topiary gardening is very old art. The Romans did it in the first Century. In the sixteenth century, people in Europe like topiaries too. By the late 1600s, topiaries were also grown in America. Today it’s popular in many parts of the world.
小題1: Put the following in the right order according to the passage.
a. The gardener chooses a bush for the topiary.
b. The whole bush grows tall enough for shaping.
c. The gardener begins to shape the bottom of the bush.
d. The gardener draws the shape of a topiary.
A．d→a→b→cB．b→c→a→dC．a(chǎn)→d→c→bD．d→a→c→b
小題2:In which part of the world did the topiary gardening begin first?
A．In Rome.B．In Europe.C．In America.D．In Africa.
