It has long been thought that first-born children are more successful than their younger brothers and sisters and often have qualities of being more organized and responsible as well as being eager to be in charge.
But a new study has shown that the elder child’s achievements can help improve their younger siblings’ exam results by helping them to raise their game. For the first time ever, researchers from the
And the data showed that having an older brother or sister improved a child’s learning with the equal effect of spending an extra £670 on the younger sibling’s schooling. One of the study’s authors Birgitta Rabe explained, the older sibling’s achievement may have a direct effect on the younger sibling’s school grades if the older sibling teaches the younger sibling or helps with homework; the younger sibling imitates（模仿） the older sibling, for example in their work style, or tries to be different, for example to avoid competition; the older sibling passes on important information about educational choices or school and teachers to the younger sibling.
The effect is even more noticeable in less well-off families showing poorer children benefit more from a successful older sibling. “We find that the effect is larger for siblings in families relying on free school meals, living in poverty and speaking a language other than English at home. This means that children who live in poverty benefit more from a successful older sibling.”
43．The study is mainly based on the children’s ________.
A. exam results B. work style
C. family background D. educational choices
44．Which of the following is closest in meaning to the underlined word “well-off”?
A. Poor B. Wealthy C. Happy D. Unfortunate
45．What can we conclude from the study?
A. Younger siblings are more successful than first borns.
B. First-born children are as successful as their younger siblings.
C. First-born children are more successful than their younger siblings.
D. The success of first borns has positive effects on their younger siblings.
46．The passage is likely to appear in ________.
A. a newspaper advertisement
B. a high school textbook
C. a science magazine
D. a news report
Harvard researchers have created a tough, low-cost, biodegradable(可生物降解的) material inspired by insects’ hard outer shells. The material’s inventors say it has a number of possible uses and someday could provide a more environmentally friendly alternative to plastic. The material, made from shrimp(虾)shells and proteins produced from silk, is called “shrilk”. It is thin, clear, flexible and strong.
A major benefit of the material is its biodegradability. Plastic’s toughness and flexibility represented a revolution in materials science during the 1950s and 1960s. Decades later, however, plastic’s very durability(耐用性) is raising questions about how appropriate it is for one-time products such as plastic bags, or short-lived consumer goods, used in the home for a few years and then cast into a landfill where they will degrade for centuries. What is the point of making something that lasts 1,000 years?
Shrilk has great potential, the inventors said. Materials from which it is made are plentiful in nature, found in everything ranging from shrimp shells, insect bodies to living plants that makes shrilk low cost, and its mass production possible should it be used for products demanding a lot of material.
Work on shrilk is continuing in the lab. The inventors said the material becomes flexible when wet, so they’re exploring ways to use it in wet environments. They’re also developing simpler production processes, which could be used for non-medical products, like for computer cases and other products inside the home. They’re even exploring combining it with other materials like carbon fibers, to give it new properties.
47．Paragraph 1 of the passage is mainly about shrilk’s ______________.
A. remarkable design B. interesting name
C. major features D. basic elements
48．What has become a problem about plastic?
A. Using it properly B. Producing it cheaply
C. Developing its properties quickly D. Evaluating its contributions fairly
49．According to the inventors, shrilk has great potential partly because _________.
A. it can help plastic degrade B. it can be found in living things
C. it is in great need now D. its raw materials are plentiful in nature
50. Which of the following statements is NOT true according to the passage?
A. The disadvantage of plastic’s durability is obvious.
B. Shrilk can be made from everything in nature.
C. Shrilk is still under research and not put to use.
D. The inventors are optimistic about the new material.

In old times, there was a story about a young athletic boy hungry for success, for whom winning was everything.
One day, the boy was preparing himself for a running competition in a small village. He and two other young boys were to compete. A large crowd had gathered to witness the competition and a wise old man, upon hearing of the little boy, had travelled far to bear witness, too.
The race started. Sure enough, the boy dug deep and showed his determination, strength and power. He came first. The crowd cheered and waved at the boy. The wise man remained still and calm. The little boy, however, felt proud and important.
A second race was called, and two new young challengers came forward to run with the little boy. The little boy finished first once again. The crowd again cheered and waved at the boy. The wise man expressed no opinion.
“Another race, another race!” shouted the little boy. The wise man stepped forward and presented the little boy with two new challengers, a weak old lady and a blind man. “What is this?” quizzed the little boy. “Race!” said the wise man. The race was started and the boy was the only finisher. The little boy raised his arms in delight. The crowd, however, was silent showing no happiness.
“Why don’t they join in my success?” he asked the wise old man. “Race again,” replied the wise man. “This time, all three of you, finish together,” continued the wise man. The little boy thought a little, stood in the middle of the blind man and the weak old lady, and then took the two challengers by the hand. The race began and the little boy walked slowly, ever so slowly, to the finishing line and crossed it. The crowd cheered and waved at the boy. The wise man smiled.

I visited a zoo yesterday, and I was very unhappy and angry about the things what I saw. The large animals were in small cages. The lion was walking to back and forth. It was completely bored. The tiger fell asleep all the afternoon. I saw people feeding the fish. They were throwing rice and meat into the pond, which could kill the fish, but no one tries to stop them. When he had a drink at the zoo restaurant, the waiter served me rude. Outside the restaurant, the rubbish bins were full and rubbish was blowing everywhere. It seems that the zoo doesn’t look after the animals or the visitors very good.
