Question

   Deserts are areas of the world that are extremely dry. They don't get much rain. Officially a desert is an area that gets less than 10 inches of precipitation (降 雨) a year. Deserts don't necessarily have to be hot. Some of the world's largest deserts are cold deserts located at one of the Earths poles or in a cold area of the world. One thing is for sure,deserts are dry and barren places.

   Antarctic Desert (南極荒漠) 

   This is the world's largest desert and is located at the South Pole. Basically the entire continent of Antarctica is considered a desert because it gets very little precipitation. The Arctic desert covers the North Pole. They are both called polar deserts.

   Sahara Desert 

   The Sahara Desert is the largest non-polar desert in the world. It is located in North Africa,is nearly as large as Europe or the United States. The name Sahara comes from the Arabic word for desert,sahra. Areas of the Sahara Desert look like the classic desert you see in the movies sometimes with giant sand dunes that can get over 500 feet tall!There are oases of life in the Sahara such as the area along the Nile River in Egypt.

   Kalahari Desert 

   The Kalahari Desert is located in Southern Africa. Like many deserts,it has large temperature swings,with temperatures dropping to zero at night and then rising to above 40 degrees C ( 104 degrees F) in the day.

   Mohave Desert 

   The Mohave Desert is located in the Southwest of the United States. It is home to Death Valley,the hottest and lowest spot in the US. Mohave Desert means high desert and is named after the Mohave tribe of Native Americans.

Answer 1

  沙漠是指地面完全被沙所覆蓋、植物非常稀少、雨水稀 少、空氣干燥的荒蕪地區(qū)。本文向我們介紹了南極荒漠、撒 哈拉沙漠、喀拉哈里沙漠和莫哈維沙漠這四大沙漠。

1. A 細(xì)節(jié)理解題。由第二段的 because it gets very little precipitation可知，南極大陸是一個沙漠是因為那里全 年基本上不下雨，由此可知正確答案為A項。

2. C詞義猜測題。由畫線詞后面的that can get over 500 feet tall可知，有500多英尺高的應(yīng)該是沙丘。由此可猜測 dimes在此可與hills相互替換，意為“沙丘”。

3. C細(xì)節(jié)理解題。倒數(shù)第二段提到了“The Kalahari Desert is located in Southern Africa. ”，由此可知嗜拉哈里沙漠 在非洲南部，故正確答案為C項。

4. D細(xì)節(jié)理解題。由最后一段“The Mohave Desert is located. .. It is home to Death Valley." 可知，死亡谷 位于莫哈維沙漠。由此可知正確答案為D項。

5. A推理判斷題。本文主要介紹的是南極荒漠、撒哈拉沙漠、喀拉哈里沙漠和莫哈維沙漠的相關(guān)情況。由此可 推斷本文應(yīng)該摘自地理方面的雜志，故選A項。

necessarily adv.必要地，必需地 barren adj.貧瘠的

consider v.認(rèn)為，把……看作

tribe n.部落

障礙句分析

   Areas of the Sahara Desert look like the classic desert you see in the movies sometimes with giant sand dunes that can get over 500 feet tall!撒哈拉沙漠地區(qū)看起來就像你有時在電影 中看到的那種經(jīng)典沙漠，巨大的沙丘有500多英尺高！

   ... you see in the movies是省略了關(guān)系代詞的定語從 句，修飾desert; look like意為“看起來像”；介詞with意為 “具有，帶有”；“數(shù)字+長度單位+ tall”表示“……高”。
