Like cats, geckos(壁虎)always land on their feet. If they happen to fall from a wall or leaf they’ve been climbing, a quick move of the tail makes sure that they always land on their feet first, a new study finds.
Geckos are truly built for climbing: their feet have hairy toes that can fix themselves to a wall or other vertical(竖直的)surfaces. However, geckos’ feet can’t always keep hold and they may fall to the ground. When geckos fall or jump off a wall, they always land stomach-side down. Geckos’ long tails become necessary during their falls, the new study shows.
Researchers did an experiment. They placed geckos up-side-down on the underside of a leaf. When they lost their foothold and fell, the geckos pitched (倾斜)their tails for balance. They then rotated(旋转)their tails to make their bodies rotate. As soon as they were right-side up, they stopped rotating. On average, it only took the geckos about a tenth of a second to right themselves so that they would land on their feet.
Cats use a different way to land on their feet after a fall. As their tails don’t have the power like geckos’ tails, cats can’t use them to right themselves. Instead they twist their bodies around mid-air.
Engineers are trying to build a robot that imitates the geckos’ climbing ability. A tail will be fixed to the robot to allow it to keep balance.
54. What do we know about geckos?
A. Their toes make it possible for them to walk on walls.
B. Their tails can fix them to a wall or other vertical surfaces.
C. They often land on their backs when they jump off walls.
D. It takes them a second to right themselves in mid-air.
55. How do cats avoid their injury during a fall?
A. By twisting their bodies.                 B. By fixing their toes to the ground.
C. By using their tails to right themselves.        D. By landing upside-down.
56. Geckos’ special abilities have given engineers some new ideas to _________.
A. allow robots to climb vertical surfaces       
B. reproduce geckos like robots
C. invent robots that can rotate on the ground
D. invent robots that can balance themselves using their tails
57. What is the text mainly talking about?
A. The interesting living habits of geckos.   B. The differences between cats and geckos.
C. Why geckos always land on their feet.      D. How geckos climb up vertical walls.

A farmer grew some vegetables in his garden. One day his wife was ill and he had no money. He had to sell some cabbages and carrots in the market. The next morning he took two baskets of vegetables to town, but it was raining hard that afternoon and there were few people in the street. When his vegetables were sold out, it was dark. He bought some medicine and hurried to his village.
On his way home he saw a person lying on the ground. He placed his baskets on the ground and was going to help the person to get up. At that time he found it was a dead man and there was much blood on his body. He was so afraid that he ran away quickly, without taking his baskets.
The next afternoon the farmer was sent to the police station.

Still seeking a destination for your weekend break? There are some places which are probably a mere wall away from your college.
King’s Art Centre
A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists.
You could attend a class teaching you how to ‘learn from the masters’ or get more creative with paint – free of charge.
The Centre also runs two life drawing classes for which there is a small fee.
The Botanic Garden
The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.
The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.
Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.
The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called ‘Hissing Sid’ is regularly seen lying in the heat of the warm sun.
Byron’s Pool
Many stories surround Lord Byron’s time as a student of Cambridge University. Arriving in 1805, he wrote a letter complaining that it was a place of “mess and drunkenness”. However, it seems as though Byron did manage to pass the time pleasantly enough. I’m not just talking about the pet bear he kept in his rooms. He spent a great deal of time walking in the village.
It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron’s Pool. A couple of miles past Grant Chester in the south Cambridge shire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don’t trust me, then perhaps you’ll take it from Virginia Woolf – over a century after Byron, she reportedly took a trip to swim in the same pool.
As mentioned in the passage, there is a small charge for ____.

A.attending the masters’ class
B.working with local artists
C.learning life drawing
D.seeing an exhibition

“Torch Aloe” and “Venus Flytrap” are ____.

A.common insects
B.impressive plants
C.rarely-seen snakes
D.wildlife-enthusiasts

D.to finish university in 1805

In the passage Byron’s Pool is described as a lake ____.

A.surrounded by fields

Like many new graduates, I left university full of hope for the future but with no real idea of what I wanted to do. My degree, with honors, in English literature had not really prepared me for anything practical. I knew I wanted to make a difference in the world somehow, but I had no idea how to do that. That’s when I learned about the Lighthouse Project.
I started my journey as a Lighthouse Project volunteer by reading as much as I could about the experiences of previous volunteers. I knew it would be a lot of hard work, and that I would be away from my family and friends for a very long time. In short, I did not take my decision to apply for the Lighthouse Project lightly. Neither did my family.
Eventually, however, I won the support of my family, and I sent in all the paperwork needed for the application. After countless interviews and presentations, I managed to stand out among the candidates and survive the test alone. Several months later, I finally received a call asking me to report for the duty. I would be going to a small village near Abuja, Nigeria. Where? What? Nigeria? I had no idea. But I was about to find out.
After completing my training, I was sent to the village that was small and desperately in need of proper accommodation. Though the local villagers were poor, they offered their homes, hearts, and food as if I were their own family. I was asked to lead a small team of local people in building a new schoolhouse. For the next year or so, I taught in that same schoolhouse. But I sometimes think I learned more from my students than they did from me.
Sometime during that period, I realized that all those things that had seemed so strange or unusual to me no longer did, though I did not get anywhere with the local language, and I returned to the United States a different man. The Lighthouse Project had changed my life forever.

I fell in love with England because it was quaint (古雅)—all those little houses, looking terri­bly old-fashioned but nice, like dolls’ houses. I loved the countryside and the pubs, and I loved London. I’ve slightly changed my mind after seventeen years because I think it’s an ugly town now.
Things have changed. For everybody, England meant gentlemen, fair play, and good man­ners. The fair play is going, unfortunately, and so are the gentlemanly attitudes and good man­ners—people shut doors heavily in your face and politeness is disappearing.
I regret that there are so few comfortable meeting places. You’re forced to live indoors. In Paris I go out much more, to restaurants and nightclubs. To meet friends here it usually has to be in a pub, and it can be difficult to go there alone as a woman. The cafes are not terribly nice.
As a woman, I feel unsafe here. I spend a bomb on taxis because I will not take public trans­port after 10 p. m. I used to use it , but now I’m afraid.
The idea of family seems to be more or less non-existent in England. My family is well united and that’s typically French. In Middlesex I had a neighbor who is 82 now. His family only lived two miles away, but I took him to France for Christmas once because he was always alone.
The writer doesn’t like London because she ______.

A.is not used to the life there now
B.has lived there for seventeen years
C.prefers to live in an old-fashioned house
D.has to be polite to everyone she meets there

Where do people usually meet their friends in England?

A.In a cafe. B.In a restaurant.
C.In a nightclub. D.In a pub.

The underlined part “it” (in Para. 4) refers to______.

A.a taxi B.the money
C.a bomb D.public transport

The writer took her neighbors to France for Christmas because he ______.

A.felt lonely in England
B.had never been to France
C.was from a typical French family
D.didn't like the British idea of family

Samuel Osmond is a 19-year-old law student from Cornwall, England. He never studied the piano. However, he can play very difficult musical pieces by musicians such as Chopin and Beethoven just a few minutes after he hears them. He learns a piece of music by listening to it in parts. Then he thinks about the notes in his head. Two years ago, he played his first piece Moonlight Sonata(奏鸣曲)by Beethoven. He surprised everyone around him.
Amazed that he remembered this long and difficult piece of music and played it perfectly, his teachers say Samuel is unbelievable .They say his ability is very rare, but Samuel doesn’t even realize that what he can do is special. Samuel wanted to become a lawyer as it was the wish of his parents, but music teachers told him he should study music instead. Now, he studies law and music.
Samuel can’t understand why everyone is so surprised. “I grew up with music. My mother played the piano and my father played the guitar. About two years ago, I suddenly decided to start playing the piano, without being able to read music and without having any lessons. It comes easily to me ---I hear the notes and can bear them in mind---each and every note,” says Samuel.
Recently, Samuel performed a piece during a special event at his college. The piece had more than a thousand notes. The audience was impressed by his amazing performance. He is now learning a piece that is so difficult that many professional pianists can’t play it. Samuel says confidently,” It’s all about super memory---I guess I have that gift.”
However, Samuel’s ability to remember things doesn’t stop with music. His family says that even when he was a young boy, Samuel heard someone read a story, and then he could retell the story word for word.
Samuel is still only a teenager. He doesn’t know what he wants to do in the future. For now, he is just happy to play beautiful music and continue his studies.
What is special about Samuel Osmond?

A.He has a gift for writing music.
B.He can write down the note he hears.
C.He is a top student at the law school.
D.He can play the musical piece he hears.

B.Samuel planned to be a lawyer rather than a musician.
C.Samuel thinks of himself as a man of great musical ability.
D.Samuel studies law and music on the advice of his teachers.
