There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. And some do one simple job. When an automatic washing machine is switched on , water pours in. The machine waits until the water is warm enough for washing clothes. It does this by “feedback(反馈)” . Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us . So robots are like human beings in two ways.
They work and they have feedback.
In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done, A person moves the robot’s “arms” and “hands” through each part of the job.
The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive robots are used in scientific research. They do such jobs as handling radioactive materials.

I live in north Celebes which is near Philippines. Since early December 2010 most tropical regions have been frequently hit by rain. Just like my hometown, tropical regions only have two seasons, including the dry season that usually starts from April to September and the wet or rainy season which usually happens from October to March. But, it could be indeterminate. Sometimes the rainy season can come a month earlier or later. It can be prolonged even more than 4 months and so can the dry season. Even during the dry season, rain can occur several times in certain areas.
The prolonged dry season in tropical areas usually causes a lot of losses. It will be very harmful to local farmers, because most of the tropical areas sre regions of the developing countries. Sometimes agricultural and plantation crops will be damaged because of so much dry land and the fact that the river used to flow the water for rice fields are also dry. Rain is very important for plants because rain contains many nutrients that plants are in great need of.
What’s more, if the prolonged rainy season arrives and then floods usually occur in certain areas of low lands. Even for the capital city of Jakarta floods have struck several times during the prolonged rainy season. In addition to floods, the rainy season can cause many diseases. During the dry season, diseases are usually caused by mosquitoes such as dengue fever. While in the rainy season, people who have the weak immune will be more easily attacked by some diseases such as flu, fever, diarrhea, and much more.
If you live in the other places and want to travel to the tropical regions, make sure that you have known much about the season and the effect for these months in which you want to travel as tourists. Only in that way, can you at least prepare to deal with tropical weather.

I want to talk about the economy．Not "the economy" we hear about endlessly in the news each day and in politicians' speeches．I want to talk about the real economy, the one we live in day by day．
Most people aren't particularly interested in "the economy"．"Share prices are flying high; interest rates are soaring; the Dow Jones Index closed sixty-three points down on 8472．35．" We hear this and subconsciously switch off．
Notice that "the economy" is not the same as the economy, "The economy" is what men in suits play with to make vast personal wealth．The economy is where the rest of us live on a daily basis, earning our living, paying our taxes, and purchasing the necessities of life．
We are supposed to be benefiting from all the advantages of a well-off society．So why do we feel tired and stressed? We have no time for anything other than work, which is ridiculous given the number of labor-saving devices in our lives．Our towns become more and more crowded．We poison our air and seas, and our food is full of chemicals．There's something wrong here．If times were truly good, then you may think we'd all feel optimistic about the future．Yet the majority of us are deeply worried．More than 90 percent of us think we are too concerned about ourselves and not concerned enough about future generations．
The term "economic expansion" suggests something desirable, but expansion simply means spending more money．More spending doesn't mean that life is getting better．We all know it often means the opposite - greed, crime, poverty, pollution．More spending merely feeds our whole economic system, which is based on production and consumption．Unless money keeps circulating, the economy breaks down．If we don't keep consuming, the whole system goes into stalemate（僵局）．
How do we break the cycle and make some changes? We need to become far more aware of the results of our actions．We buy clothes that are made in sweat shops by virtual slaves in poor parts of the world．We create mountains of waste．We demand cheap food, mindless of the fact that it totally lacks taste and is produced using chemicals that poison the land．
The consumption culture makes us unaware of the effect of our own behavior．Our main problem is not that we don't know what to do about it．It is gathering the desire to do it．

Not even Dan Brown and his Da Vinci code—breakers(密码破译者)dared deal with the mystery of Mona Lisa，s smile．But Nicu Sebe，a computer expert the University of Amsterdam，the Netherlands，did．He used’emotion recognition’software to process the famous painting and found Mona Lisa happy(83 per cent)and slightly disgusted(厌烦的)(9 per cent)．
Faces show emotions. Psychology，computer science，and engineering researchers are joining forces to teach machines to read expressions．If they succeed，your computer may one day“read”your mood．Machines equipped with emotional skills could also be used in teaching，gaming，mind－reading，etc.
“Mind Reader”，a system developed by Rosalind Picard at MIT(the Massachusetts Institute of Tech’nology)in the US, uses input from a video camera to do real—time analysis of facial expressions. It reports on whether you seem“interested”or“agreeable”or if you’re“confused”．The system can help people recognize others’emotions．Picard says this means we could teach a machine to be as sensitive as a human．In fact，a machine can be even smarter than people since it can tell if a person is lying or just“performing”by analyzing one’s facial movements．
Jeffrey Cohn，a psychologist at the University of Pittsburgh，uses the Facial Action Coding System to recognize human emotions．The system sorts more than 40 action units(AUs)of the face to tell people’s real emotions．He studied a videotape of a criminal who said to be sad about the murder of several family members and tried to pin the blame on someone else．But Cohn saw no real sadness in the woman’s face.
Sadness is a group of AUs that is difficult to do at the same time．You have to pull down the woman’s of your lips while bringing your eyebrows together and raising them．What the woman did was raise her cheeks to make a lip cud(撇嘴)。Her brows stayed smooth．
64．The best title of this passage is“ ________ ”．
A．The emotion on your face                    B．Look at your face
C．Your face tells a story                          D．Telling a lie
65．The missing sentence“This means，even though your mouth lice，your face doesn’t，and the machine will know it all. ”should be put at the end of ___________．
A．Paragraph 2   B．Paragraph 3      C．Paragraph 4     D．Paragraph 5
66．How many facial emotion analyses are mentioned in this passage?
A．Four．               B．Three．              C．Two．         D．One
67．The underlined word“it”refers to________．
A．MIT                                 B．the video camera
C．one’s face emotion            D．the real—time analysis

Pigs are always considered dirty animals because they roll in mud．But in fact they prefer being quite clean．They cover themselves with mud to help stay cool．During cooler weather, they prefer to stay clean．So do elephants,who also cover themselves in dust or mud to keep cool． When they find a place with clean water they will take a bath，using their long noses to give themselves—or each other—a nice shower
Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don`t like to take water baths because water is not warm enough for them．So, instead, they roll around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease
Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any parasites(寄生虫)between the crocodile`s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．
You wouldn`t think fish would need baths．But some undersea parasites live under the fish`s skin．“Cleaner”fish，like the wrasse(隆头鱼)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out parasites and bits of food．
【小题1】The passage is mainly about how animals ．
