American middle school students don’t seem to care that they’re worse at maths than their counterparts (同龄人) in China’s Hong Kong and Finland. “I don’t need it,” my student says, “I’m going to be a basketball star.” Or a car mechanic, or a singer.
Middle school students’ maths skills were tested by the International Organization for Economic Co-operation and Development. The United States ranked 28th out of 41 countries tested. After all, when was the last time you used algebra (代数)？
But maths isn’t just about training Americans to become scientists. It has its own value. It helps you see patterns and develops your logic skills, and it teaches you to concentrate and to separate truth from falsehood. Maths helps you make wise financial decisions, so you can avoid false claims from advertisers, politicians and others. It helps you determine risk. For example, after an airplane crash, studies show that people are more likely to drive than to take a plane in spite of the fact that they are much more likely to be killed or injured while driving. Planes are not like criminals who repeat the same crime over and over. One plane is not more likely to crash just because another plane recently did. In fact, the most dangerous time to drive is probably right after a plane crash because so many people are on the road.
It is not possible to really understand science and the scientific method without understanding maths. A rainbow is even more beautiful and amazing when we understand it.
The precision (精确性) of maths helps us think in a very special way. How do we bring the learning of maths back to life? I don’t have the big answer. I try my best to help pupils find answers to some maths problems. When I can get one to say, “Wow, that’s great,” I feel the joy of a small victory.Some American students don’t care about their poor maths results because __________.
| A．maths is useless to most people |
| B．they have no interest in maths |

This text is most probably written by __________.
| A．a student career guide | B．a researcher on students’ problems |

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut he greenhouse gases they send out, which are thought to be responsible for global warming.
Thanks to special bacteria in their stomachs, kangaroo flatulence(肠胃气胀)contains no methane(甲烷)and scientists want to transfer that bacteria to cattle and sheep who produce large quantities of the harmful gas.
While the usual image of greenhouse gas pollution is a billowing smokestack (烟囱) pushing out carbon dioxide, farm animals’ passing wind contribute a surprisingly high percentage of total emissions (排放物)in some countries.
“Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep,” said Athol Kleve, a senior research scientist with the Queensland state government.
“And if you look at another country such as New Zealand, which has got a much higher agricultural base, they're actually up around 50 percent, ” he said.
Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.
But it will take researchers at least three years to isolate (分离) the bacteria, before they can even start to develop a way of transferring it to cattle and sheep.
Another group of scientists, meanwhile, has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.
The idea is controversial (有争议的), but about 20 percent of health-conscious Australians are believed to eat the national symbol already.
“It's low in fat, it’s got high protein levels and it's very clean in the sense that basically it's the free-range (放养的) animal,” said Peter Amp of the University of New South Wales's institute of environmental studies.Scientists intend to put bacteria into cattle and sheep _________.
| A．so that they can make full use of special bacteria |
| B．to help Australian farmers to earn more money |
| C．so that they can protect Australian ecosystem |
| D．to prevent them from sending out harmful gases |
Athol Kleve seems to believe that ________.
| A．cattle and sheep produce more carbon dioxide |
| B．less cattle and sheep are raised in New Zealand |
| C．farm animals are responsible for greenhouse gases |
| D．New Zealand has the most animals in the world |
What do the underlined words “the idea” in paragraph 9 refer to?
| A．Australians should farm fewer cattle and sheep and just eat more kangaroos. |
| B．The bacteria could make the digestive process much more efficient. |
| C．Australians should give kangaroo - style stomachs to cattle and sheep. |
| D．The bacteria could save millions of dollars in feed costs for farmers. |
Which of the statements is the advantage Peter Amp lists about kangaroo?
| A．it is rich in protein | B．it is cheaper than beef |
| C．it is high in fat | D．it is more delicious than sheep |
Last week, President Barack Obama gave a back- to-school speech to students at the Julia R. Masterman Laboratory and Demonstration School in Philadelphia, Pennsylvania. Students in schools across the country also tuned in to watch the President's speech on TV. He stressed the importance of trying new things, working hard and believing in yourself.
While admitting that times are tough for families across the country, Obama reminded students that hard work now can mean big success later. “Nobody gets to write your destiny(命运）but you,” he said. “Your future is in your hands. Your life is what you make of it. And nothing—absolutely nothing—is beyond your reach."
Obama spoke about his own life, and lessons he learned from his mother, who had to remind him to stay focused on his studies. He told students the recipe (诀窍) for success: “Showing up to school on time. Paying attention in class. Doing your homework. Studying for exams. Staying out of trouble. ”
Obama encouraged students to embrace(欣然接受)what makes them different. “We shouldn't be embarrassed by the things that make us different,” he said. “We should be proud of them.”
He also suggested taking advantage of all of the opportunities at your school, and always being open to trying new things. “Just because you’re not the best at something today doesn't mean you can't be tomorrow,” he said. “Even if you don't think of yourself as a math person or as a science person—you can still excel in those subjects if you're willing to make the effort. And you may find out you have talents you’d never dreamed of.”What does Obama mainly want to tell the students in Paragraph 2?
| A．Some families are experiencing a hard time. |
| B．Different people have different destinies. |
| C．They can create their own future. |
| D．Those who don't study hard will achieve nothing. |

Most animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership(伙伴关系) which does good to both of them. You may have noticed some birds sitting on the back of sheep. This is not because they want a ride, but because they find easy food in the parasites(寄生虫）on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.
Sometimes an animal has a plant partner. The relationship develops until the two partners cannot do without each other. This is so in the corals(珊瑚）of the sea. In their skins they have tiny plants which act as “dustman”, taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from light so that they cannot live normally, the corals will die.Some birds like to sit on a sheep because _________.
| A．they can eat its parasites |
| B．they consider the sheep as their shelter |
| C．they enjoy traveling with the sheep |
| D．they find the position most comfortable |
The underlined word “they” in the first paragraph refers to _______.
| A．birds and parasites | B．sheep, birds and parasites |
| C．parasites and sheep | D．birds and sheep |
It can be learnt from the text that the coral depends on the plants for ________.
| A．comfort | B．light | C．oxygen | D．food |
What does the second paragraph mainly discuss?
| A．Some plants depend on each other for food. |
| B．Some animals and plants develop their relationship easily. |
| C．Some animals and plants depend on each other for existence. |
| D．Some animals live better together. |
What’s in name? Well, apparently, our general happiness. Psychologists say that what we are called has a direct connection with our happiness.
Those called Judy and Joshua are the happiest, while Lynn or Ben is likely to be the unhappiest, according to research. Psychologist Dr David Holmes found that this can cause the association(联想) that others make with the name. Hearing the name Judy may make them think of actress Judi Dench or TV presenter Judy Finnigan, and people who are considered good-natured and happy. On the other hand, people think Paulines are unhappy because of the character Pauline Fowler from the TV programme East Enders. The research claims that this association influences the person with the name and so their personality is shaped to fit in. Dr David Holmes said, “This also has some relation with the original meaning of the name, for example, the original meaning of Judy is ‘praised’.”
Certain names also work well in certain aspects of life. In the workplace Richard and Judy are the happiest, while those called Ruth and Carly are the happiest in relationships. At the other end of the scale the unhappiest workers are Stuart and Liz, with the unhappiest in relationships being Frank and Harriet.
Dr Holmes said, “The relation we have with certain names, particularly important namesakes (同名者), also shapes how we see ourselves and so may have an effect on our confidence. Names are like product brands in having a powerful effect on attitudes and should therefore be chosen with care.”
“Other names are connected with being brave, outgoing or serious. Therefore, many celebrities change their names to ones which reflect these characteristic. This, in turn, influences parents when they choose names for their babies,” said Dr Holmes, “while names connected with ordinary people are rarely chosen for their babies.”What’s the main idea of this passage?
| A．How to choose a good name for babies. |
| B．The relation between names and happiness. |
| C．How to have a name connected with celebrities. |
| D．The relation between names and success. |
According to the passage, which of the following names are better?
| A．Joshua and Ben. | B．Pauline and Frank. |
| C．Richard and Stuart. | D．Ruth and Joshua. |
The author may continue the passage with _________.
| A．names and product brands |
| B．famous people’s names |
| C．names and personality |
| D．parents’ choices of baby names |
Which of the following is connected with names according to the passage?
| A．Personality and self-confidence. | B．Self-confidence and position. |
| C．Position and characteristic. | D．Personality and appearance. |
