In most situations, light helps us see. But nowadays humans are using so much that it is in fact a kind of pollution.
When it comes to looking at the night sky, too much light makes it d  小題1:  for us to watch some of life’s most wonderful views: stars, p  小題2:  and even galaxies(星系).
According to scientific research, about 2, 500 stars can be seen by the human eye without u  小題3:  any special equipment(設備). But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. In most big c  小題4:, people cannot see the sky filled with stars like they did in their childhood.
Light pollution affects more than just our view of sky. Research s  小題5:  that lots of nighttime light can harm wildlife, too.
When birds fly to a  小題6:  place over cities, they sometimes get lost by the brightness and fly in circles(圈) u  小題7: they drop from tiredness. Sea turtles need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights.
Too much light at night m  小題8:  even affect human health, but scientists are not sure of that. They are still learning more.
In order to prevent things from going w  小題9:, governments and some organizations are working to reduce light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used only when and where they are r  小題10:  needed.
Hopefully, in the near future, humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed life, too.

試題分析：這篇短文主要介紹了光污染。隨著人類生活的進步，太多的燈光也成為了一種污染。本文詳細的介紹了燈光污染的危害，并提出了相應的建議。
小題1:聯(lián)系下文描述，可知此處指的是讓我們很難看見一些生活中最精彩的景色，結合首字母可知填形容詞difficult，困難的，做賓語補足語。
小題2:聯(lián)系上下文，可知此處指的是行星，星球，故填復數(shù)名詞planets。
小題3:聯(lián)系下文，可知此處指的是用任何特殊的設備。Without是介詞，后面接名詞或者動名詞做賓語，結合首字母可知填動名詞using，用，作賓語。
小題4:聯(lián)系上下文，可知此處指的是大城市，結合首字母可知填復數(shù)名詞cities，城市。
小題5:句意：研究表明夜間的燈光也能傷害野生動物。結合語境可知本句描述的是客觀性動作，故用一般現(xiàn)在時態(tài)。主語research是抽象名詞，不可數(shù)，故謂語動詞用單數(shù)。填：shows，顯示，說明。
小題6:聯(lián)系下文，可知此處指的是當一只鳥越過城市飛到另一個地方時……，結合首字母可知填不定代詞another，多個中的另一個。

點評：首字母一直是英語考試中的難點，得分率比較低。解答此類題型的方法一般就是根據(jù)文章前后句子之間意思推斷出詞義，并結合首字母推斷出所缺單詞，然后根據(jù)該單詞在句子中的句子成分，所起作用，確定單詞詞形，進行適當詞形變化。

閱讀下面短文，根據(jù)短文內(nèi)容回答問題。
What to go on holiday, but don’t have enough money for luxury (豪華的) hotels and expensive trips? Backpacking might be right up your street.
Backpacking is a very cheap kind of travel. European and American students and young adults who may not have all that much money often do it. It is called backpacking because, instead of using a suitcase (手提箱), people put all their things in a large backpack. A backpack sits on your back, and you pack all your clothes inside.
The most popular places for backpacking are Southeast Asia and South America. These countries aren’t very expensive, and are also very hot for most of the year. India and Australia are also very popular. In 2002, over 400,000 backpackers hit Australia. Sometimes, backpacking can be dangerous. A British backpacker was recently shot dead at a beach party in Thailand, and every year similar things happen.
Backpacking, in fact, is much more than a holiday—for young people in Europe, it is seen as a way of learning about the world.
Backpackers often travel alone for many months, as this is seen as more of an adventure and challenge. Beyond finding new words, backpacking, people say, is all about “finding yourself”.
小題1:Is backpacking an expensive kind of travel?
                                                                                    
小題2:Why is it called backpacking?
                                                                                     
小題3:Where are the most popular places for backpacking?
                                                                                  
小題4:How many backpackers traveled to Australia in 2002?
                                                                                
小題5:What do people think of backpacking?

"USA? Britain? Which country is better to study in?" We often hear such discussions. As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world.
It's true that studying abroad can help students develop themselves. Their foreign language  skills will be improved and it may be easier to find jobs．
But there are problems that should be considered．Language is the first．Students must spend a  lot of time 1earning another language．
Students must also leam to live without parents’care and deal with all kinds of things they haven't had to do before，like looking after themselves．There are reports about Chinese students  abroad running into an ocean of difficulties and giving up finally．When they have to take care of  themselves，it is hard for students to study well．
Finally，studying abroad brings a heavy burden(負擔) to most Chinese  parents，the cost of studying abroad is very high .But is it worth it?
We know that there are many famous people who have succeeded in great things through their    hard work in China．Liu Xiang is a good example．Once an American teacher invited him there，but    he refused． He kept training hard with his Chinese teacher. He surprised the world when he won a     gold medal at the Athens Olympic Games . So when you wonder which country is better to study in，think again.
