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(zhǎng)） 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 ________.
A．a(chǎn)re better than human in seeing and hearing
B．a(chǎn)re as capable as those in Star Wars
C．can pick up objects more quickly than humans
D．sometimes perform wrong actions

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length (5.5 cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.
【小題1】The earliest frogs lived about          million years ago.

A．20
B．30
C．50
D．190
【小題2】      can jump over 2m.
A．The Goliath Frog
B．The Common Wood Frog
C．The Poison Frog
D．The Australian Rocket Frog
【小題3】What will happen to a Common Wood Frog at very low temperature?
A．It will die very soon.
B．It will be an ice frog.
C．It will become dangerous.
D．It will become very small.

Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists (靈學(xué)家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a“sixth sense”really exists, Robert Baker, a psychologist (心理學(xué)家) at the University of Kentucky, did two experiments.
In the first one, Baker sat behind unknowing people in public places and stared(盯著）at the backs of their heads for 5 to 15 minutes. The subjects（受試者）were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker,“I suggest they repeat the experiments and see for themselves.”
【小題1】The aim of the two experiments is to ________.

A．explain when people can have a sixth sense
B．study how people act while being watched in the lab
C．study whether humans can sense when they are stared at
D．prove why humans have a sixth sense
【小題2】The underlined word “outcome” in the last paragraph most probably means ________.
A．valueB．resultC．performanceD．connection
【小題3】In the second experiment, the subjects _________.
A．could tell when they were stared at
B．could tell where they weren’t stared at
C．couldn’t tell who they were stared at or who they stared at
D．couldn’t tell when they were stared at or when they weren’t
【小題4】What can be learned from the passage?
A．People are born with a sixth sense.
B．The experiments support parapsychologists’ idea.
C．The subjects do not have a sixth sense in the experiments.
D．People have a sixth sense in all places.
