Walking Robot Carries a Person
The first walking robot capable of carrying a person unveiled on Friday in Tokyo, Japan. Its creators at Waseda University in Tokyo and the Japanese robotics company
Tmsuk hope their two-legged creation will one day enable wheel-chair users to climb up and down the stairs and assist the movement of heavy goods over uneven ground.
The battery-powered robot, code-named WL-16, is essentially an aluminium chair mounted on two sets of telescopic poles. The poles are bolted to flat plates which act as feet. WL-16 uses 12 actuators (传动装置) to move forwards, backwards and sideways while carrying an adult weighing up to 60 kilograms (130 pounds)。 The robot can adjust its body and walk smoothly even if the person it is carrying shifts in the chair. At present it can only step up or down a few millimeters, but the, team plans to make it capable of dealing with a normal flight of stairs.
I believe this bipedal (两足的) robot, which I prefer to call a two-legged walking chair rather than a wheel-chair, will eventually enable people to go up and down the stairs,“ said Atsuo Takanishi, from Waseda University.
“We have had strong robots for some time but usually they have been manipulators, they have not been geared to carrying people around,” says Ron Arkin, at the Georgia Institute of Technology and robotics consultant for Sony. “But I don’t know how safe and how user-friendly WL-16 is.”
Tmsuk chief executive Yoichi Takamoto argues that bipedal or multi-legged robots will be more useful than so-called “caterpillar (毛毛虫) models” for moving over uneven ground.
WL-16’s normal walking step measures 30 centimetres, but it can stretch its legs to 136 cm apart. The prototype (原型) is currently radio-controlled, but the research team plans to equip it with a stick-like controller for the user in future. Takanishi said it will take “at least two years” to develop the WL-16 prototype into a working model.
Smaller, ground-hugging (紧贴地面行走的) robots have been developed to pass across tricky ground. One maggot-like (像蛆一样的) device uses a magnetic fluid to pulse its way along, while another snake-like robot uses smart software to devise new movement strategies if the landscape affects any one part. One ball-shaped robot even uses a leap-and-bounce approach to travel over rough territory. But none of these are big or strong enough to carry a person too.

Operation Migration If you look up at the sky in
Operation Migration
If you look up at the sky in the early fall in the northern part of North America, you may see groups of birds. These birds are flying south to places where they can find food and warmth for the winter. They are migrating(迁徙). The young birds usually learn to migrate from their parents. They follow their parents south. In one unusual case, however, the young birds are following something very different. These birds are young whooping cranes, and they are following an airplane!
The whooping crane is the largest bird that is native to North America. These birds almost disappeared in the 1800s. By 1941, there were only about 20 cranes alive. In the 1970s, people were worried that these creatures were in danger of disappearing completely. As a result, the United States identified whooping cranes as an endangered species that they needed to protect.
Some researchers tried to help. They began to breed whooping cranes in special parks to increase the number of birds. This plan was successful. There were a lot of new baby birds. As the birds became older, the researchers wanted to return them to nature. However, there was a problem: These young birds did not know how to migrate. They needed human help.
In 2001, some people had a creative idea. They formed an organization called Operation Migration. This group decided to use very light airplanes, instead of birds, to lead the young whooping cranes on their first trip south. They painted each airplane to look like a whooping crane. Even the pilots wore special clothing to make them look like cranes. The cranes began to trust the airplanes, and the plan worked.
Today, planes still lead birds across approximately 1,200 miles (1,931 kilometers), from the United States-Canadian border to the Gulf of Mexico. They leave the birds at different sites. If a trip is successful, the birds can travel on their own in the future. Then, when these birds become parents, they will teach their young to migrate. The people of Operation Migration think this is the only way to maintain the whooping crane population.
Operation Migration works with several other organizations and government institutes. Together, they assist hundreds of cranes each year. However, some experts predict that soon, this won’t be necessary. Thanks to Operation Migration and its partners, the crane population will continue to migrate. Hopefully, they won’t need human help any more.

第三篇Trying to Find a Parther One of the most stri
第三篇Trying to Find a Par ther
One of the most striking findings of a recent poll in the UK is that of the people interviewed ,one in two believes that it is becoming more difficult to meet someone to start a family with,
Why are many finding it increasingly difficult to start and sustain intimate relationships?Does modern life really make it harder to fall in love?Or are we making it harder for ourselves?
It is certainly the case today that contemporary couples benefit in different ways from relationships,Women no longer rely upon partners for economic security or status,A man doesn’t expect his spouse to be in sole charge of running his household and raising his children,
But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence,
In theory,finding a partner should be much simpler these days,Only a few generations ago,your choice of soulmate (心上人) was constrained(限制) by geography,social convention and family tradition,Although it was never explicit,many marriages were essentially arranged,
Now those barriers have been broken down,You can approach a builder or a brain surgeon in any bar in any city on any given evening,When the world is your oyster (牡蛎),you surely have a better chance of finding a pearl,
But it seems that the old conventions have been replaced by an even tighter constraint:the tyranny of choice,
The expectations of partners are inflated(提高) to an unmanageable degree:good looks,impressive salary,kind to grandmother,and right socks,There is no room for error in the first impression,
We think that a relationship can be perfect,If it isn’t,it is disposable,We work to protect ourselves against future heartache and don’t put in the hard emotional labor needed to build a strong relationship,Of course,this is complicated by realities,The cost of housing and child-rearing creates pressure to have a stable income and career before a life partnership,
41,What does the recent poll show?
A,It is getting more difficult for a woman to find her husband,
B,It is getting increasingly difficult to start a familyl,
C,It is getting more difficult for a man to find his wife,
D,It is getting increasingly difficult to develop an intimate relationship with your spouse,
42,Which of the following is NOT true about a contemporary married couple?
A,The wife doesn’t have to raise the children all by herself,
B,The husband doesn’t have to support the family all by himself,
C,The wife is no longer the only person to manage the household,
D,They will receive a large sum of money from the government,
43,Which of the following was NOT a constraint on one’s choice of soulmate in the old days?
A,The health condition of his or her grandmother,
B,The geographical environment,
C,The social convention,
D,The family tradition,
44,Which of the following is NOT expected of a partner according to this passage?
A,Good looks,
B,An impressive career,
C,A high salary,
D,A fine sense of humor,
45,The word“sustain”(paragraph 2)could be best replaced by
A,“reduce”,
B,“shake”,
C,“maintain”,
D,“weaken”,

第二篇 Teaching poetry
第二篇 Teaching poetry
No poem should ever be discussed or “analyzed”, until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it.
All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling “interpretation” of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching can not replace the student and teacher reading it or, best of all, reciting(背诵) it.
I have come to think, in fact, that time spent reading a poem aloud is much more important than “analyzing” it, if there isn’t time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is “ a criticism of life”, and “ a heightening(提升) of life”. It is “an approach to the truth of feeling”, and it “ can save your life”. It also deserves a place in the teaching of language and literature more central than it presently occupies.
I am not saying that every English teacher must teach poetry. Those who don’t like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few thing s about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.
36 To have a better understanding of a poem, one should
A discuss it with others.
B analyze it by oneself.
C copy it down in a notebook
D practise reading it aloud
37 Which of the following is NOT mentioned as a function of poetry?
A Extending your life.
B Saving your life.
C Criticizing life.
D Heightening life.
38 According to the writer, one of the purposes of teaching English is to get students
A to understand life.
B to enjoy poetry.
C to become teachers.
D to become poets
39 What does the last sentence in the third paragraph imply?
A More stress should be laid on the teaching of poetry.
B Poetry is more important than any other subject.
C One cannot enjoy life fully without an understanding of poetry
D Poetry is the foundation of all language and literature courses
40 The phrase “make room” in the last paragraph could be best replaced by
A “build a booth”
B “provide equipment”.
C “leave a certain amount of time”.
D “set aside enough space”.
