Question

【題目】The rise in temperature is a result of the greenhouse effect (溫室效應). And it helps keep the earth warm enough for people， plants and animals to live on. There are some natural gases like CO2 around the earth. These gases create (產生) something like a blanket around us. The blanket lets in the heat (熱量) of the sun and keeps it near the ground. It is like how a real greenhouse works.

It is important to understand the greenhouse effect. Some of the things we do every day can change the temperature of our earth. If factories， cars， and other things are making lots of new waste gases， the earth will get warmer. In the end， it will become too hot for us to live on.

【1】 The underlined word “it” in the passage means _______.

A. the temperature of the earth

B. what many scientists think

C. the greenhouse effect

D. the gas around the earth

【2】 The blanket around us is made up of _______.

A. wood B. plants C. gases D. sunlight

【3】Which is the best title for the picture?

A. How a Greenhouse Works

B. Planting Flowers in a Greenhouse

C. Why the Heat Gets Trapped

D. The Importance of the Sun

【4】Where is the passage probably taken from?

A. A weather report. B. fashion magazine.

Answer 1

【答案】

【1】C

【2】C

【3】A

【4】D

【解析】

試題分析：短文大意：該文主要介紹了溫度的上升是溫室效應的結果。我們必須能采取措施來控制溫室效應防止地球變暖。

【1】C詞義猜測題。根據(jù)前句The rise in temperature is a result of the greenhouse effect可知it指代的是“溫室效應”，所以選C。

【2】C細節(jié)理解題。根據(jù)第一段中These gases create (產生) something like a blanket around us.可知這些氣體在我們周圍創(chuàng)建了像毯子一樣的東西。所以選C。

【3】A標題歸納題。根據(jù)圖中的文字可知該圖示說明了溫室效應的工作原理，所以選A。

【4】D細節(jié)理解題。根據(jù)該文主要介紹溫室效應可知它最有可能出自于有關環(huán)境的論文，所以選D。
