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

A desert is a very dry land where there is hardly any rain. In the day, it can be so hot that you could fry an egg on the ground. But during the night it is sometimes so could that water would turn into ice.






Many desserts are covered in sand. But some have mountains, rocks, or lakes that have dried up in the heat. The Great American Dessert has cliffs(悬崖) that have been made into amazing and beautiful shapes by the wind. The Sahara Desert in Africa is mostly sand. The Australian Desert has red sand.
Sometimes it does not rain for a whole year in the desert. But there is water deep under the ground and some plants have roots that go very deep to find it. Other plants have roots that spread out(延伸) a long way so they can suck up the rain as soon as it falls.
One desert plant is the cactus, which has long, spreading roots. The cactus stores water inside its hard skin. This skin protects it from heat and cold.
Camels are a bit like cactus plants! They store water too—inside their bodies. They have special fur which protects them from the sun during the day and keeps them warm at night.
Some other animals live in deserts, too. They have to be very good at seeing and hearing because most of them only come out at night. This is why many desert animals have extra big eyes or ears.
A desert fox has bigger ears than a normal for. A gerbil has huge eye, so that it can see at night. It stays cool in the day by staying underground, like most desert animals.
Some people live in the desert but they always make their homes near an oasis. An oasis is where water comes from an underground river. Near an oasis, people can grow lots of plants and keep animals.
Life is hard in the desert, for people, animals and plants. But desert people like to live there.
A desert is very dry because__________.

A.it is sandy B.there is so little rain
C.the wind is strong D.there is no water deep under the ground

What does the underlined phrase"suck up"in paragraph 3 mean_________?

A.围堵 B.讨好 C.释放 D.吸收

One of the greatest mysteries on Earth is the statues which stand on Easter Island. Easter Island, which was almost uninhabited when it was discovered on Easter Day in 1722 by a Dutch captain, is the most distant island in the world covered with hundreds of giant statues, each weighing several tons and some standing more than 30 feet tall.
Who built these statues and why and how did they get there? Nobody knows the answer for sure.
One theory suggests that Easter Island was first inhabited by Polynesians, who traveled thousands of miles in their canoes(独木舟)in 400 A.D. However, the ocean currents(洋流)which carried them there would not take them back, so that they could not leave.
The statues appear to have been made out of the top edge of the walls of a volcano on the island. Then, it may have been rolled or dragged down to the foot of the volcano(火山). Then, it was stood upright(直立)and ropes were tied around it, which was made to act as a pulley(滑轮). Over a period of months, a statue could be walked for miles down to the ocean. Finally, it was placed in line with other statues, all of them looking towards the center of the island.
This process was difficult. If a statue fell over, it was too heavy to be pulled upright again, so the islanders went back and carved another statue.
The population of Easter Island must have reached 11,000. Later, the resources of the island were used up and people began fighting and eating each other. Work on the statues stopped and the statues were knocked over. When the first Europeans finally arrived on the island, most of these people had died out.
This passage is mainly about ________ .

A.the discovery of Easter Island B.the statues on Easter Island
C.the history of Easter Islanders D.the earliest population on Easter Island

Which of the following correctly tells of the possible working process after a statue was made?
a. It was stood upright and ropes were tied around it.
b. It was walked for miles down to the ocean.
c. It was placed in line with other statues.
d. It was moved to the foot of the volcano.

A.c-d-a-b B.d-b-a-c C.a-c-b-d D.d-a-b-c

It’s not a fact that ________ .

A.Easter Island is the most distant island in the world
B.Easter is the name of a holiday
C.not all the statues were placed in a line
D.the island was once rich in natural resources

The underlined word uninhabited most probably means ________.

Have you ever been in a meeting while someone was making a speech and realized suddenly that your mind was a million miles away? You probably felt sorry and decided to pay attention and never have daydreaming again. Most of us have been told from earliest school days that daydreaming is a waste of time.
L. Giambra, a psychologist(心理学家), says,” On the contrary , daydreaming is quite necessary. Without it, the mind couldn’t do all the thinking that it has to do during a normal day. You can’t possibly do all your thinking with a conscious (神志清醒的)mind. Instead, your unconscious mind is working out problems all the time. Daydreaming may be one way that the unconscious and conscious states (状态)of mind have silent conversations .”
Early psychologists paid no attention to the importance of daydreams or even thought they were harmful. At one time people thought that some psychological illness caused day dreaming. They did not have a better understanding of daydreams until the late 1980s. Eric Klinges, a professor, is the writer of the book Daydreaming. Klinges says, “We know now that daydreaming is one of the main ways that we organize our lives, learn from our experiences, and plan for our futures. Daydreams really are a window on the things that we fear and the things we long for (渴望) in life.”
Daydreams are usually very simple and direct(直接), quite unlike sleep dreams. Sleep dreams may be hard to understand. It’s easier to get a deep understanding of your life by paying close attention to your daydreams than by trying to examine (分析)your sleep dreams carefully. Daydreams help you know the difficult situations(情况)in your life and found out a possible way of dealing with them.
Daydreams cannot be predicted(预言): they move off in unexpected directions which may be creative and full of useful ideas. For many famous artists and scientists, daydreams were and are a main source of creative energy.
The passage is mainly about _______ .

A.winter sleeps B.sleep dreams C.daydreaming D.predictions

The underlined phrase On the contrary  means _________ .

A.总之 B.相反 C.毕竟 D.因此

The writer of this passage thinks daydreams are__________.

A.hard to understand B.important and helpful
C.harmful and unimportant D.the same as sleep dreams

Psychologists now believe that ________.

A.daydreams are usually very simple and can be predicted
B.daydreams are usually difficult to understand
C.daydreams cause some psychological illness
D.daydreams may be creative and full of useful ideas

The writer quoted  (引用 )L. Giambra  and Eric Klinges  to ________.

A.list out two different ideas
B.point out the wrong ideas of early experts
C.support his own ideas
D.report the latest research on daydreams

Happiness is important for everyone. Most people want to be happy but few know how to find happiness. Money and success don’t bring lasting happiness. Happiness depends on ourselves. In other words, we make our own happiness.
Some people believe that if they are wealthy, they will be able to do anything they want, which means happiness. On the other hand, some people believe that holding a high position in the government is happiness. In this way, you have not only money, but also many other things which can’t be bought by money. However, other people believe that having lots of money is not happiness, nor is holding a high position in the government. These people value(重视) their beliefs, or their intelligence, or their health. They think these can make them happy.
Here are a few ways to help you be happier.
The first secret of happiness is to enjoy the simple things in life. Too often, we spend so much time thinking about the future, for example, getting into college or getting a good job, that we don’t enjoy the present. You should enjoy life’s simple pleasures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have close friends usually enjoy happier and healthier lives.
The second secret of happiness is to be active. Many people go dancing or play sports. People can forget about their problems and only think about the activities.
Finally, many people find happiness in helping others. According to studies, people feel good when they volunteer their time to do many meaningful things for other people. If you want to feel happier, do something nice for someone. You can help a friend with his or her studies, go shopping to get food for an old neighbor, or simply help around the house.
Now maybe you know how to find happiness!
The underlined word “wealthy” means “__________” in the article.

A.pleased B.healthy C.excited D.rich

Passage 1  Mobile Phone Madness
How much do you love your mobile phone? A Chinese student had to call 110 for help this week after he got his arm stuck in a toilet trying to rescue(援救) his mobile phone. After dropping his phone in the toilet, he decided to wrap(包,裹) his arm in newspaper in the hopes of keeping clean. But the newspapers became larger in size in the water, and then even his roommates couldn’t help him pull his arm out. So policemen were called and they spent an hour unsticking the stuck student.
Passage 2  Crazy Pet Lovers
How much do you love your pets? Many people in China are famous for how much they love their pets. They dress them up in fashionable clothing and buy them high quality food. But would they spend 7,000 English pounds (68,000 yuan) on a wedding(婚礼) for their pets? And that’s what a couple in Brazil spent on a fancy wedding for their pet Yorkshire terriers( a kind of dog).
Passage 3  Oh, rats!
When something goes wrong, you can often hear Westerners cry “Oh, rats”. But when it comes to Southern China, “Oh, rats!” can mean it’s what you want for dinner. According to a report in China Daily, some restaurants in Guangzhou serve rat meat. But, actually, most of those rats are field mice. What would Mickey Mouse say?
Passage 4  Liar(说谎者), liar
Here’s some news that most women already know. Men tell more lies than women.
