Question

【題目】 Look at the following. It shows a cross-section (橫截面) of a mountain and the land on each side of it. The sea is on the west side of the mountain.

In January, February and March, warm wet winds blow strongly across the sea towards (朝) the mountain. The winds pick up moisture (濕氣) as they blow across the sea. When clouds reach the mountain, they rise and become cooler. The higher they have to go, the cooler they become. The moisture in the clouds turns to rain. As a result, the clouds drop rain on the west side of the mountain. Some of the clouds pass over the mountain, but there is little rain in them.

In July and August, strong winds blow from G towards the mountain. They pass over a wide desert, where it is always very hot. The winds become hot and dry. They rise when they meet the mountain. They do not form clouds because there is no moisture in the hot air.

The diagram shows why there are wonderful farms on one side of the mountain, but there is a desert on the other side.

【1】Suppose (假設(shè)) it is in the northern part of the Earth, which season is dry?

A.Spring.B.Winter.C.Autumn.D.Summer.

【2】After reading the passage, what is the most important cause of the rain?

A.The mountain.B.The clouds.C.The sea.D.The desert.

【3】Why do NOT the winds from G form clouds?

A.Because there is no moisture in the hot air.

B.Because the winds don't pass over the desert.

C.Because the winds are not strong enough.

D.Because the winds don't reach the mountain.

【4】From the passage we know ________.

A.point G is to the west of point A

B.there is little rain on the east side of the mountain

C.when the winds meet the mountain, they always form clouds

D.the higher the clouds go, the warmer they become

Answer 1

【4】B

【解析】

本文主要通過山脈的橫截面圖的地理知識來介紹我們?yōu)槭裁瓷降囊幻媸歉火埖霓r(nóng)場，而另一面是是沙漠。

【1】推理判斷題。由In July and August, strong winds blow from G towards the mountain. They pass over a wide desert, where it is always very hot. The winds become hot and dry. They rise when they meet the mountain. They do not form clouds because there is no moisture in the hot air. 在七月和八月，強風從G吹向山。他們經(jīng)過一片廣闊的沙漠，那里總是很熱。風變得又熱又干。他們遇到山就起來了。它們不會形成云，因為熱空氣中沒有水分。可以推知夏季氣候炎熱，不會形成云，不會降水，氣候就會干燥。故選D。

【2】細節(jié)理解題。由warm wet winds blow strongly across the sea towards (朝) the mountain. The winds pick up moisture (濕氣) as they blow across the sea. When clouds reach the mountain, they rise and become cooler. The higher they have to go, the cooler they become. The moisture in the clouds turns to rain. As a result, the clouds drop rain on the west side of the mountain. 可以推知降雨是因為云中含有濕氣，而濕氣是由于風吹過海面時會吸收濕氣 ，所以降雨最重要的原因是海洋，故選C。

【3】細節(jié)理解題。由 The winds become hot and dry. They rise when they meet the mountain. They do not form clouds because there is no moisture in the hot air.可知因為熱空氣中沒有水分，它們不會形成云。故選A。

【4】細節(jié)理解題。由As a result, the clouds drop rain on the west side of the mountain. Some of the clouds pass over the mountain, but there is little rain in them.可知云在山的西側(cè)降下了雨。有些云從山上飄過，但很少下雨�？芍�在山的東側(cè)很少降雨，故選B。
