【題目】One day, around Christmas time, fishermen off the west coast of Peru started on their traditional fishing trip. Much to their surprise, there were no fish! They knew immediately what had happened. Tales from years gone by had told them this was the result of El Nino which sometimes stop fishing for many months!

El Nino is a warm current that comes and goes along the west coast of South America. It got its name from fishermen in Peru more than a century ago. Every few years, they noticed a sudden warming in the normally cool Pacific water where they fished. Because this warming often came about around Christmas, they called it El Nino, which is Spanish for the “Christ Child”. Generally, El Nino occurs every three to seven years and lasts only a few weeks to a month or more.

El Nino warms the water it flows through. Because the fish and sea birds need cold water to live, many of them die when El Nino comes through. El Nino also causes both floods and droughts. It is believed that El Nino may have caused the 1993 Mississippi and 1995 California floods. And at the same time, it may have caused droughts in South America, Africa and Australia.

El Nino has occurred thirteen times within the last fifty years, bringing natural disasters to many countries such as Indonesia and Peru. However, El Nino does not often trouble China. During this period China was badly hit by El Nino only once. In 1998, North China had a terrible drought, while South China was troubled by floods.

【1】The underlined word "current" （in Paragraph 2）most probably refers to “______”.

A. water B. wind C. atmosphere D. climate

【2】According to the passage, which of the following is TRUE about El Nino?

A. It happens in November and December.

B. It was named by some Spanish fishermen.

C. It only happens in South America.

D. It lasts a few weeks or more.

【3】If El Nino happens, the following will take place EXCEPT ______.

A. rises in temperature of the sea water

B. diseases spreading around the world

C. floods and droughts

D. death of fish and sea birds

【4】The purpose of this passage is ______.

A. to discuss the prevention of El Nino

B. to explain how El Nino trouble farmers

C. to let us know about El Nino

D. to tell us how to prepare for El Nino

【答案】

【1】A

【2】D

【3】B

【4】C

試題分析：本文是一篇說(shuō)明文，讓人們了解更多關(guān)于El Nino。

【1】A詞義猜測(cè)題。根據(jù)后面that comes and goes along the west coast of South America.m沿著南美西部海灣流動(dòng)。第三段第一句El Nino warms the water it flows through. El Nino使溫暖的水流過(guò)。可推知?jiǎng)澗�單詞的意思最有可能是：水流.故選A。

【2】D細(xì)節(jié)理解題。根據(jù)最后一段最后一句El Nino occurs every three to seven years and lasts only a few weeks to a month or more. El Nino每3到7年發(fā)生一次，持續(xù)幾周到一個(gè)月或更長(zhǎng)時(shí)間。故選D。

【3】B細(xì)節(jié)理解題。第三段第一句El Nino warms the water it flows through. El Nino使溫暖的水流過(guò)，也就是讓海水的溫度升高；排除A；根據(jù)El Nino also causes both floods and droughts. El Nino也帶來(lái)洪水和干旱�？膳懦鼵；根據(jù)Because the fish and sea birds need cold water to live, many of them die when El Nino comes through.魚(yú)和海鳥(niǎo)需要冷水，所以當(dāng)El Nino經(jīng)過(guò)時(shí)他們當(dāng)中很多會(huì)死去的。可排除D。故選B。

【4】C主旨大意題。根據(jù)第三段第一句El Nino warms the water it flows through. El Nino使溫暖的水流過(guò)，也就是讓海水的溫度升高；根據(jù)第三段第三句El Nino also causes both floods and droughts. El Nino也帶來(lái)洪水和干旱；根據(jù)第三段第一、二句Because the fish and sea birds need cold water to live, many of them die when El Nino comes through.魚(yú)和海鳥(niǎo)需要冷水，所以當(dāng)El Nino經(jīng)過(guò)時(shí)他們當(dāng)中很多會(huì)死去的�？v觀全文，介紹El Nino的情況就是為了讓人們了解更多關(guān)于El Nino。故選C。

【名師點(diǎn)撥】

抓住文章主線和關(guān)鍵詞語(yǔ)，歸納文章中心

要注意不是所有的段落都有主題句，有時(shí)主題句暗含在句中。閱讀這樣的文章，就需要自己根據(jù)文章的細(xì)節(jié)來(lái)分析，概括出段落的主題，從而推導(dǎo)出文章的主旨。分析的方法是：先弄清該段落主要講了哪幾方面的內(nèi)容，這些內(nèi)容在邏輯上有什么聯(lián)系，然后加以歸納形成主題。比如第35小題C主旨大意題。根據(jù)第三段第一句El Nino warms the water it flows through. El Nino使溫暖的水流過(guò)，也就是讓海水的溫度升高；根據(jù)第三段第三句El Nino also causes both floods and droughts. El Nino也帶來(lái)洪水和干旱；根據(jù)第三段第一、二句Because the fish and sea birds need cold water to live, many of them die when El Nino comes through.魚(yú)和海鳥(niǎo)需要冷水，所以當(dāng)El Nino經(jīng)過(guò)時(shí)他們當(dāng)中很多會(huì)死去的。縱觀全文，介紹El Nino的情況就是為了讓人們了解更多關(guān)于El Nino。故選C。

It is impossible to know when you might find yourself lost in a forest. If you know what to do, you can survive in a forest without much trouble; but if you are not prepared, survival can be much less likely.

Keep fear at bay

It is completely natural to be afraid when you are faced with a survival situation. 【1】 The more your fear overcomes you, the lower your chances are of survival, as your mind is going to become clouded and panic may set in.

Stay warm

Obviously, the low body temperature is one of the primary dangers you face when you must survive in the forest【2】 Never stop to sleep or quit moving around unless you have appropriate shelter.

Know how to make a fire

Obviously , if you have a lighter or matches, this is not a problem. But if not, you can attempt to use a dry narrow pointed stick and a dry flat piece of wood. 【3】 This requires a great deal of work, but if done correctly, you will succeed.

Make some shelter

【4】 The easiest way to provide protection is to find a fallen tree and cover it with other branches and brush so that you can stay in the natural pit underneath the tree trunk.This is a very important aspect of being able to survive in the forest.

Stay put unless you know exactly where you are

If you can build a stable shelter and start a fire, you can survive in the forest for several days. 【5】 If/span> you know where you are, travel as far as possible during the day while making sure you stop long enough before dark so that you can build another shelter.

A. Soon you will find that it’s not that difficult to survive in the forest.

B. However, if you are going to survive in the forest, you must keep your thoughts clear.

Why is setting goals important? 【1】 Instead of just letting life happen to you, goals allow you to make your life happen.

Successful people imagine how their life should be and set lots of goals. 【2】 It's like having a map to show you where you want to go. Think of it this way. There are two drivers. One has a destination in mind which can be found on a map. She can drive straight there surely without any wasted time of wrong turns. The other driver has no goal, or destination or map. She starts off at the same time from the same place as the first driver, but she drives aimlessly around, never getting anywhere, just using up gas. Which driver do you want to be?

【3】 They decide what they want in life and then get there by making plans and setting goals. Unsuccessful people usually just let life happen by accident. Goals aren't difficult to set and they aren't difficult to reach. 【4】 You are the one who must decide what to achieve and in what direction to aim your life.

【5】 Written goals can be reviewed regularly, and have more power. Like a contract with yourself, they are harder to neglect or forget. Also when you write your goals in a particular way, you are able to make yourself continuously aware of situations that will bring you nearer to your goal.

A．Winners in life set goals and follow them through.

B．Research tells us that when we a goal down we are more likely to achieve it.

C．It's up to you to find out what your goals really are.

D．It's difficult for a driver to reach his destination without a map.

E．By setting goals you are taking control of your life.

F．Because goals can help you do, be, and experience everything you want in life.

G．Because everybody should have a goal in his mind.
