____you are rotating the sling, the two forces balance each other out and____the stone keeps going round and round. If you____the sling midway, the sling will fly off.

A satellite works in the same way. One of the two____forces acting on the satellite is the force of gravitation. ____force is that which is created by the rotation of the satellite____the earth.

【解析】【1】由于前面提到10,9,8……是火箭發(fā)射前倒計(jì)時(shí)的聲音，所以用“聽起來(lái)像”。

【2】根據(jù)engine“發(fā)動(dòng)機(jī)”判斷，此處為“點(diǎn)火”，所以用hire。fire“雇用”；break“打破”；rush“沖”，都不合語(yǔ)義。

【3】escape“逃脫；脫離”；根據(jù)前面的“給它所必需的能力”判斷，此處為“火箭脫離地球的引力”。

【4】universe, world和stars前面都要加the。space“太空”，前面不加冠詞。

【5】stay up“呆在上面”；put up“舉起”；keep up“保持”；take up“占用”。根據(jù)下文的falling down判斷要選A。

【6】might“或許”，表示“可能性”。此處表示“你或許會(huì)問(wèn)”。dare“敢”；should/ought to“應(yīng)該”，與語(yǔ)義不符。

【7】side“邊上”，top“頂部”；middle“中間”；end“末端”，只能是把石頭“綁在”繩子的末端。

【8】watch“觀看”；notice“注意到”；examine“仔細(xì)檢查”；observe“觀察”。下文提到的是轉(zhuǎn)動(dòng)繩子時(shí)所“注意到”的情況。

【9】隨著繩子的轉(zhuǎn)動(dòng)，繩子伸直，也就自然變得“緊”了。根據(jù)下文的tighten也可看出該答案。

【10】下文解釋的繩子變緊的原因，所以用why。

【11】provide“提供”。provide an answer to...“給……提供了答案”。

【12】根據(jù)stay up(高高在上)看，后面的意思應(yīng)該與此相反，所以填fall down“掉下來(lái)”。

【13】此處指“有兩種力作用在石頭上”。force“力”；power“能力；權(quán)力”；strength“力量”；energy“精力”。

【14】根據(jù)下文的take the stone away from you判斷，另一種是把石頭朝你這邊“拉”的力。drag表示“拖”沉重的東西。

【15】while“當(dāng)……的時(shí)候”，表示動(dòng)作同時(shí)發(fā)性。

【16】therefore“因此”。根據(jù)語(yǔ)義上下文為順接關(guān)系，“兩種力平衡，因此石塊持續(xù)轉(zhuǎn)動(dòng)”。

【17】根據(jù)下文的“繩子會(huì)飛走”，判斷，此處應(yīng)為“松開繩子”，所以用release。

【18】根據(jù)下文看，一種是把石塊拉向你的力，一種是把石塊拉走的力，所以這兩種力是“相反的”。

【19】由于是兩種力，兩者中的“另一個(gè)”要用the other。another表示“三者或三者以上中的另一個(gè)”。

【20】rotation“旋轉(zhuǎn)”，既然是旋轉(zhuǎn)，所以要“圍繞”著地球。

【題目】Australia’s koalas could be wiped out within 30 years unless urgent action is taken to stop the losing in population, according to researchers. They say development, climate change and bushfires have all combined to reduce the number of wild koalas sharply.

The Australian Koala Foundation said a recent survey showed the population could have dropped by more than half in the past six years. Previous estimates put the number of koalas at more than 100,000, but the latest calculations suggest there could now be as few as 43,000.

The foundation collected field data from 1,800 sites and 80,000 trees to calculate the numbers. In one area in northern Queensland estimated to have 20,000 koalas a decade ago, a team of eight people could not find a single animal in four days of searching.

The foundation said besides problems caused by cutting down forests, hotter and drier conditions because of global warming had reduced the nutritional value of their staple food, eucalyptus leaves, leading to poor nutrition for them.

Koalas, which live in the forests in Australia’s east and south, are very fussy (愛(ài)挑剔的) about what types of the leaves they eat.

Foundation chief Deborah Tabart said: “The koalas are missing everywhere we look. It’s really no tree, no me. If you keep cutting down trees you don’t have any koalas.”

She is hoping the new figures will persuade the government’s Threatened Species Steering Committee (TSSC) to list the koala as threatened. But committee chairman Bob Beeton said a decision was not likely recently and the koala’s status as one of the country’s favourite animals would not be a factor. “There’s a number of species which are attractive and people have special feelings towards them. We don’t consider that,” Mr Beeton was reported as saying by the AFP agency.

【1】The writer gives the example of the area in northern Queensland in Paragraph 3 to show that _____.

A. the forests are being damaged heavily

B. the environment is being polluted seriously

C. koalas usually live in wild mountainous areas

D. the number of koalas is dropping quickly

【2】Global warming is an important cause of koalas’ reduction because _____.

A. koalas can hardly stand the hot weather

B. the leaves koalas eat are losing nutritional value

C. koalas cannot get enough water to drink

D. the leaves koalas eat cannot grow in hot weather

【3】According to Bob Beeton, _____.

A. koalas are his favourite animals

B. a decision will be made to protect koalas

C. they needn’t pay special attention to koalas

D. koalas needn’t be protected at all

How to Make Friends at School

Humans are social beings who thrive(興旺) on feeling accepted by other people. This is not different for kids or adults. 【1】 There are so many cliques in school. So, what happens when a child is too shy to find a group of friends? 【2】

Build up confidence. Focus on what you are confident about, whether it would be math, science,track, or chess.Are there any clubs at school associated with these interests?

【3】 .People love to talk some questions about themselves. Just listen and remember points that they make, so you can bring them up at a later time.

Use friendly gestures. Try smiling and laughing a bit when talking to others. This will help loosen you up and make you feel more relaxed.

Give it time. As social skills start to develop in the early pre-teen years, you will find it easier to communicate with others. It will take its natural course.

【題目】閱讀下列短文，從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中，選出最佳選項(xiàng)。

A

There are no signs of little green men on Mars. But new discoveries offer a bit more hope that some form of life existed there in the past --- and perhaps is still there in the present. Methane gas(甲烷) and water have been found on the Red Plane. The presence of both suggests at least the possibility of life.

According to a new report in the journal, Science, the Mars rover, Curiosity, has detected spikes of methane in the Martian atmosphere. This gas is also found in the Earth’s atmosphere, and comes from animal and plant life, as well as from the environment itself. If there’s methane in Mar’s atmosphere, where is it coming from? Scientists aren’t sure. But it marks a big change. In September 2013, Curiosity found almost no traces of methane in the Martian air. Just weeks later, however, the rover picked up a whiff of(一點(diǎn)點(diǎn)) the gas.

The scientists don’t know whether the methane spikes are caused by some form of biological matter or by the geology of the planet. Christopher Chyba, a professor of astrophysics and international affairs at Princeton, says it’s best not to be too hopeful about biology on the Red Planet. “Hopes for biology on Mars have had a way of disappearing once Martian chemistry has been better understood,” he says. “But figuring out what’s responsible for the methane is clearly a key astrobiological objective --- whatever the answer turns out to be.”

The discovery of water on Mars is nothing new. For decades, scientists have had evidence that it flowed across the surface of the planet billions of years ago. But according to another new report in Science, while the surface water on Mars seems to be long gone, there’s a lot more of it left than most of people realize.

This report is also based on findings from Curiosity. Paul Mahaffy, of NASA’s Goddard Space Flight Center in Maryland, led the study. He says there is enough water on Mars “to cover the surface to a depth of about 165 feet.”

It is not easy to reach this water. Most of it is locked up in ice at the planet’s poles.

【1】Why do scientists think there might be life on Mars?

A. Because the Mars rover has detected water on the planet.

B. Because there is evidence that little green men exist on the planet.

C. Because the Mars rover has found some plants on the planet.

D. Because both methane and water have been found on the planet.

【2】What is the attitude of professor Christopher Chyba towards life on Mars?

A. Optimistic B. Negative

C. Neutral D. Indifferent

【3】The water on Mars _______________.

A. still flows on its surface

B. covers the whole planet

C. is locked up in ice at the planet’s poles

D. only existed on it billions of years ago

【4】In which column of a website can we read this text?

A. Culture B. Entertainment

C. Science D. Education
