Here is an experiment （实验） to see how ants can organize some clever teamwork．
What's going on？
You can see one of the best examples of insect teamwork by watching ants．If one ant finds food，it leads others there to eat it too．They follow each other by making long trails．The ants go back and forth collecting food，to take back to their nest （穴）．When you move the fruit，the ants will still find it．But，instead of making a new direct route （路线） to the food，they will follow each other through their old trail route．
（1）What will happen if one ant finds food？
A．The ant will eat all the food．
B．The ant will watch other ants．
C．The ant will lead others to the food．
D．The ant will wait until others come．
（2）If the fruit is moved to a new position，the ants will ．
A．rail to find it
B．give up looking for it
C．make a new direct route to it
D．get to it through the old trail route
（3）Which is the correct order to do this experiment？
a．Move the fruit to a new position．
b．Find an ant．
c．Check the fruit an hour later．
d．Put a thin slice of fruit in front of the ant．
A．a﹣b﹣c﹣d B．b﹣d﹣c﹣a C．d﹣b﹣c﹣a D．c﹣a﹣d﹣b
（4）What can we learn from this experiment？
A．The experiment is done successfully in the lab．
B．Ants do the experiment to show their team spirit．
C．Careful watching does little help in this experiment．
D．We can find out some facts by doing small experiments．

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 (星球大战) . 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(企业) robots that work in factories. Industrial（工业） 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(感知物体) 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（波长） 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(传感器) pick up is a hard job. Remember, man—made brains handle(处理)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. From the passage, we can see that factory robots _________.
| A．help to improve other types of robots |
| B．are most active in industrial revolution |
| C．are playing a more important role than other types of robots |
| D．are the tallest type among robots |
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(执行) duties |
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. |
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 |
According to this passage, present home robots ________.
| A．are better than human in seeing and hearing |
| B．are as capable as those in Star Wars |
| C．can pick up objects more quickly than humans |
| D．sometimes perform wrong actions |
When do you become an adult, a grown-up? At eighteen? Twenty-one? Thirty? Adulthood may seem a long way to you, but the fact is that you are in the process of becoming an adult right now. The changes are so gradual逐步的）( that you may not notice them ,but you can be sure that they’re happening.
When you were a child, a parent or an older relative probably bought your clothes and helped you clean up your room. Now you are likely to have a clothes allowance, to care for your bedroom, and to share other cleaning chores. You may once have had trouble getting your homework finished on time. By now, you may have learned to pace yourself. You know how much time you need. Do you remember begging your parents to stop for ice cream, or take an after-school job when you want money for a new clock radio? Of course, you don’t always budget your time and your money perfectly. Your room doesn’t always pass inspection. And you are often less than even tempered when something upsetting happens. But you’re learning.
As you get older, you have more privileges(特权) and more responsibilities. You may baby-sit for younger brothers and sisters, help cook dinner, and do odd jobs to contribute to the family income. You may get to stay up to watch a late movie on television, sit in on adult conversations, take subways and buses alone, or go on camping trips with your friends. Eventually, you will have a job and an apartment of your own.
You’ll become a voter and perhaps a husband or wife, maybe even a parent. But doing things adults do does not necessarily mean you will be wiser, braver, or more self-assured. It takes time to acquire knowledge and build self-confidence. Adults need to test themselves in the world, just as you do as a teenager. Being an adult is a continual process of growth.The best title for this passage may be _____________.
| A．Becoming An Adult | B．It Is No Good Becoming An Adult |
| C．Becoming A Voter | D．Adulthood Is always A Long Way To You |
According to the passage, the writer may probably think that ________.
| A．nobody can be called an adult |
| B．becoming an adult is a long process of becoming learned and self-assured |
| C．adults are not self-confident |
| D．only adults can budget time and money perfectly |
Which of the following is NOT true according to the passage?
| A．You don’t know you’re growing up because changes are gradual. |
| B．You used to beg for toys when you were young. |
| C．Even if you are quite grown up , you still need to acquire knowledge. |
| D．People will never be wise, brave or self-assured. |
Have you ever suddenly felt that someone you know was in trouble—and he was? Have you ever dreamed something that came true later? Maybe you have ESP.
ESP stands for（代表） Extra Sensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here is an example: A woman was doing washing. Suddenly she screamed, “My father is dead!” I saw him sitting in the chair!” Just then. a telegram came. The woman’s father had died of a heart attack. He died sitting in a chair.
There are thousands of stories like this on record. Scientists are studying them to find out what is behind these strange mental messages. Here’s another example—one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, “There’s room for one more.” The man felt the driver was dead, so he ran away. The next day the man was getting on a crowded bus. The bus driver said, “There’s room for one more.” Then the man saw the driver’s face was the same face he had seen in the dream. He wouldn’t get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are lies or coincidences. Others, including some scientists say that ESP is true. From studies of ESP, we may some day learn more about the human mind.People with ESP may know about ____________
| A．someone’s trouble | B．events before they happen |
| C．their dreams | D．events after they happen |
From the passage it can be inferred that ____________.
| A．all people have ESP | B．some women or men have ESP |
| C．children have ESP | D．no have ESP |
