六、阅读理解
Imagine you are taking a walk on the beautiful beach. Just then, your feet step over something and you hear a crack(噼啪声)—an empty plastic bottle. Things like this are happening more often because of sea rubbish.
Studies show that 80% of all the waste is from the land. The waste is mainly plastics (塑料制品) which are really hard to degrade(降解). So the rubbish will remain there for a long time. Some of the pollution is caused accidentally. For example, about 10, 000 productfilled boxes are lost at sea every year from business ships. Sometimes people just throw them into the water from boats or land as they like. Many large rubbish areas are formed in the North Pacific Ocean.
Thankfully, the situation isn’t ignored (忽视). Groups like the National Oceanic Atmospheric Association(NOAA) are taking action to help clean the sea. Since 2006, 76 projects have cleared out 3, 814 metric tons (公吨) of rubbish from the sea. Methods of rubbish cleaning include using machines to remove(移除) the waste away from the surface of sea water. Besides, special nets are set by the mouths of rivers to stop the rubbish before it reaches the sea. If everyone does his part, sea rubbish seems like a problem that can be solved.
41．The sea waste made of ________ will remain for a long time.
A．paper B．wood
C．plastic D．cotton
42．In the second paragraph we can know ________ are also some of the sea rubbish.
A．special cleaning nets
B．large factory machines
C．passing business boats
D．lost productfilled boxes
43．NOAA is a group that ________.
A．stops people from fishing
B．fights against the sea pollution
C．develops trade in the seafood
D．produces new kinds of plastics
44．In order to ________, some projects are done by the river mouths.
A．prevent the rubbish reaching the sea
B．clean the surface of the dirty sea water
C．build more sea rubbish collecting areas
D．make people care about the environment
45．According to the passage, we can imagine the future of the sea will be ________.
A．terrible B．dark
C．quiet D．hopeful
At 8, 844, 43 meters high, Mount Qomolangma is the tallest mountain on Earth. While it is famous for its beautiful views, parts of the mountain are facing a problem: rubbish. Every year, thousands of visitors throw away tons of rubbish, such as bottles and plastic bags.
According to the UN, over 140 tons of rubbish has been left on the mountain. To reduce rubbish, China is limiting(限制) the number of people who are allowed to climb up the north side of the mountain. Only 300 people will be allowed to climb it, and only during spring.
Local people cleaned the mountain last year, removing rubbish at a height of 5,200 meters. They collected about 8.4 metric tons(公吨) of rubbish。
This year, the local government plans to spend 4 million yuan on a new clean-up activity. The local government is also setting up stations to sort(分类), recycle and break down rubbish collected from the mountain. A group of artists will also try to turn the rubbish into art works. They will show these works of art to remind people not to leave rubbish when climbing the mountain.
46．What problem are parts of Mount Qomolangma facing
A．Air pollution. B．Rubbish. C．Noise. D．Water pollution.
47．How many people will be allowed to climb up the north side of the mountain during spring
A．140. B．5,200 C．4 million. D．300.
48．The underlined word "removing" in Paragraph 3 probably means ____.
A．using up B．making better C．putting on D．taking away
49．The artists will show their art works in order to ____.
A．teach people to make works of art
B．help people to know about Qomolangma
C．encourage people to clean up Qomolangma
D．remind people not to throw rubbish on Qomolangma

【分析】本文介绍了珠穆朗玛峰的污染问题。珠穆朗玛峰面临着一个问题：垃圾。每年，成千上万的游客扔掉成吨的垃圾，如瓶子和塑料袋。为了减少垃圾，中国只允许300人爬山，而且只有在春天。今年，地方政府计划斥资400万元开展新的清理工作。当地政府还设立了分类站，回收和分解从山上收集的垃圾。一群艺术家也会把垃圾变成艺术品。他们将展示这些艺术作品，提醒人们爬山时不要留下垃圾。
46．细节理解题。根据While it is famous for its beautiful views, parts of the mountain are facing a problem: rubbish. 虽然它以美丽的景色而闻名，但山上的一些地方却面临着一个问题：垃圾。可知，珠穆朗玛峰的部分地区面临垃圾问题。故选B。
47．细节理解题。根据To reduce rubbish, China is limiting(限制) the number of people who are allowed to climb up the north side of the mountain. Only 300 people will be allowed to climb it, and only during spring.可知，只有300人可以爬山，只有在春天。故选D。
48．词意猜测题。A. using up用完；B. making better做得更好；C. putting on穿上；D. taking away带走。句子Local people cleaned the mountain last year, removing rubbish at a height of 5,200 meters.的意思是：当地人去年清扫了这座山，清除了5200米高的垃圾。结合语境和所给的选项可知，removing“去除，使消失”的意思。与短语taking away带走。意思相符。故选D。
49．细节理解题。根据A group of artists will also try to turn the rubbish into art works. They will show these works of art to remind people not to leave rubbish when climbing the mountain. 一群艺术家也会把垃圾变成艺术品。他们将展示这些艺术作品，提醒人们爬山时不要留下垃圾。可知，艺术家们将展示他们的艺术作品，以提醒人们不要把垃圾扔到珠穆朗玛峰上。故选D。
50．推理判断题。题干的意思是：这属于什么样的作品？A. A notice. 通知；B. News. 新闻；C. A story.故事；D. An advertisement. 广告。通知，一定要有通知的时间；本文没有时间，因此不属于通知，故排除A；新闻，新闻是关于最近所发生的新鲜而重要的报道或述评；故事，要有：时间、地点、人物、故事的起因、经过和结果，一共六个要素。本文只有地点，也不属于故事，排除C；广告，都应有五个完整的要素，具体是指：广告主、广告经营者和广告发布者、广告媒体、广告信息、消费者公众市场。根据本文的内容，可知本文是一篇重要的报道，不属于广告，应该属于新闻。故选B。
【点睛】词义猜测题是阅读理解中常见的一种题型，所猜测词汇可以是生词，也可以是熟词新义，还可以是人称代词的指代内容。词义猜测题主要考查考生根据上下文推测词义和语义的能力，突出考查对语境的分析和把握能力。常见的猜词法有：(1)利用上下文语境。猜测任何词义都离不开上下文，所以要借助上下文对需要猜测的词或短语进行合乎逻辑的推测。 (2)利用定义或解释性的线索。阅读文章中的有些生词往往在其后会有对该词进行解释说明的短语或句子，利用它们猜词义较容易 (3)利用文章的逻辑关系答题。如并列、对比、因果、转折关系等。这些逻辑关系往往通过一些相应的词或短语表达出来，如but, or, however, so, because等。(4)利用构词法知识答题。熟记一些前缀、后缀所表达的意思，不仅可以扩大词汇量，而且帮助我们猜测词义。第3小题的词义猜测题就是利用第1种解题方法。
51．例文
My name is Li Wen. I am 15 years old. I study at Sunshine Middle School.
The earth is in trouble! We need to take steps to protect the environment. Chinese government has shut up the factories that cause pollution. We use new energy, such as the sun, wind and water.
If I always remember to turn off the lights when I leave a room, I can save a lot of energy. I can save water by turning off the tap when I brush my teeth, and taking shorter showers. It is important for us to take our own shopping bags to the supermarket. I can also recycle empty bottles in my free time.
It is time for us to take action to make a greener world. Let’s do something to make a difference.
