Question

【題目】 Lake Victoria is the largest lake in Africa. It is also the second largest lake in the world. It is an important lake because it is one of the sources for the longest river in the world, the Nile River. Lake Victoria provides a source of water, food, and power for several African countries. Lake Victoria is a big part of African life.

Unfortunately, Lake Victoria has a problem. It is shrinking. There are several power stations at Lake Victoria in Uganda. These are on the Nile River, and besides producing power, they keep the water of the lake at a certain level. For the past forty years, that level has been 11.9 meter. Over the last several years, the water level has dropped by about 2.5 meters. There seem to be several reasons for this drop.

One possible reason is drought (干旱). Drought has been very bad in the area since 2000. Lake Victoria gets all of its water from rain, so the drought means less water in the lake.

However, some environmentalists believe that the real problem is the power plants (factories) on Lake Victoria. Uganda depends on those power plants for most of its power, and they made the power plants larger in 2000. Many people believe the power plants have been taking too much water off Lake Victoria. As a result, they have been asked to use less water until Lake Victoria goes back to its old level.

Whether the low water level is caused by drought or power plants, the result is the same. This is already a poor area of Africa, where many people live a really hard life. People, animals and plants around Lake Victoria will suffer even more from low water levels on the lake. Many people need Lake Victoria for fishing or growing food. Fish need the water to live, and animals need it for water.

【1】Lake Victoria is ________.

A.an important lake in Africa.B.the largest lake in the world.

Answer 1

【答案】

【1】A

【2】C

【3】D

【4】B

【解析】

文章大意：文章主要講述了非洲的水資源短缺問題，雖然烏干達(dá)建造水電站利用維多利亞湖上的水資源，但這并不是造成水資源短缺的唯一問題，所以非洲想要解決這一局面，只有尋找更多得水源。

【1】細(xì)節(jié)理解題。根據(jù)文章第一段中的“Lake Victoria is…… longest river in the world”“維多利亞湖是非洲最大的湖。它也是世界上第二大湖泊。它是一個(gè)重要的湖泊，因?yàn)樗�是世界上最長(zhǎng)河流的源頭之一”可知，維多利亞湖是非洲一個(gè)重要的湖泊，所以A說法是正確的；維多利亞湖是世界上第二大湖，所以B說法是錯(cuò)誤的；根據(jù)第一段中的“Lake Victoria provides a source of water, food, and power for several African countries”“維多利亞湖為幾個(gè)非洲國(guó)家提供水源、食物和能源”可知，維多利亞湖為非洲國(guó)家提供水源、食物和能源，不是美國(guó)，所以C說法是錯(cuò)誤的；維多利亞湖是世界上最長(zhǎng)河流的源頭之一，不是唯一一個(gè)，所以D說法是錯(cuò)誤的，故選A。

【2】詞句猜測(cè)題。根據(jù)文章第二段中的“For the past forty years, that level has been 11.9 meter. Over the last several years, the water level has dropped by about 2.5 meters”“在過去的四十年里，這個(gè)水位已經(jīng)達(dá)到了11.9米，在過去的幾年里，水位下降了大約2.5米”可推知，It is shrinking指的是這條河流在變小，It is becoming larger河變得更大了；It is becoming more beautiful河變得更美了；It is becoming smaller河變得更小了； It is becoming more useful河變得更有用了，故選C。

【3】細(xì)節(jié)理解題。根據(jù)文章第二段中的“For the past forty years, that level has been 11.9 meter. Over the last several years, the water level has dropped by about 2.5 meters”“在過去的四十年里，這個(gè)水位已經(jīng)達(dá)到了11.9米，在過去的幾年里，水位下降了大約2.5米”可知，維多利亞湖現(xiàn)在11.9-2.5=9.4米，故選D。

【4】細(xì)節(jié)理解題。根據(jù)文章最后一段中的“Whether ……the water to live, and animals need it for water”“無論是干旱還是電廠造成的低水位，結(jié)果都是一樣的。這已經(jīng)是非洲的一個(gè)貧困地區(qū)，許多人在那里過著非常艱苦的生活。維多利亞湖周圍的人、動(dòng)物和植物將因湖上的低水位而遭受更大的損失。許多人需要維多利亞湖捕魚或種植食物。魚需要水來生存，動(dòng)物需要水來喝水”可知，圍繞維多利亞湖的問題，解決的最好辦法是尋找更多的水源，故選B。
