Question

【題目】 At the beginning of November 2018, the 35th Chinese Antarctic expedition（南極科考隊）set off for the polar（極地的）region. This time, one of their main tasks is to build China’s first permanent（永久的）Antarctic airport, Science and Technology Daily reported.

There are more than 20 airports in Antarctica, according to Global Times. But none of them belongs to China. China’s polar plane Xueying 601 has to take off and land at Russian airports.

The new airport will help Chinese aircraft take off and land in the South Pole. This will make it easier to transport scientific equipment and do research.

In order to be environmentally friendly, the airport will be small, said Sun Bo, the leader of the research team. However, this doesn’t make it easy to build the airport.

The site of the airport is an ice cap, which is a thick layer of ice. It covers the land like a quilt. But this “quilt” is always moving. Scientists have to find the slowest-moving part of the cap. You can hardly notice the movement of the ice in this area.

The next problem is the snow. The snow on the ice cap can be very thick. Also, it is as soft as cotton, which makes it hard to build a runway for airplanes. Scientists have to use a snow blower to get rid of the snow on the top of the cap. Then, they compact the rest of the snow with a road roller-like machine. In this way, the snow will be strong and hard enough to build a runway on the top of the cap.

【1】The main purpose of the 35th Chinese Antarctic expedition is to _________.

A.transport scientific equipmentB.do some research

C.set up a research stationD.build an airport

【2】What is the main idea of the third paragraph?

A.Explaining why we need to explore Antarctica.

B.Explaining where China’s polar planes take off and land.

C.Explaining what the new airport in Antarctica can do.

D.Explaining how other countries build their own airports.

【3】The new airport in Antarctica will be small because _________.

A.there is no more areas in Antarctica

B.the plane is smaller than usual

C.we should try to protect the Antarctic environment

D.the snow is difficult to clear off

【4】The underlined word “compact” in Paragraph 6 refers to _________.

A.壓緊B.鏟除C.凍結D.融化

【5】Which of the following is not the difficulty of building a polar airport according to the passage?

A.The weather changes very often.B.The ice cap is always moving.

C.The snow on the ice cap is thick.D.The snow on the ice cap is soft.

Answer 1

【答案】

【1】D

【2】C

【3】C

【4】A

【5】A

【解析】

本文是一篇說明文。文章介紹了中國將在南極建立第一座永久性機場。

【1】細節(jié)理解題。題干意為：中國第35次南極科考隊的主要目的是________。根據文章第一段最后一句“This time, one of their main tasks is to build China’s first permanent Antarctic airport, Science and Technology Daily reported.”可知，此次科考隊的主要目的之一是建一座永久性南極機場。故選D。

【2】主旨大意題。題干意為：第三段的主要內容是什么？根據文章第三段內容可知，此段重點講了新機場的用途。故選C。

【3】細節(jié)理解題。題干意為南極的新機場將會很小是因為________。根據文章第四段第一句“In order to be environmentally friendly, the airport will be small, said Sun Bo, the leader of the research team.”可知，為了對環(huán)境友好，機場將會很小。故選C。

【4】詞句猜測題。題干意為：第六段劃線單詞“compact”指的是________。根據本段中最后一句“In this way, the snow will be strong and hard enough to build a runway on the top of the cap.”可知，通過這種方法使得雪變得堅硬，足以在上面建一條跑道，由此可推知，此處指用機器將雪壓緊。故選A。

【5】細節(jié)理解題。題干意為：根據這篇文章，下面哪一項不是建立南極機場的困難之處？A項：天氣變化無常；B項：冰蓋總是在移動；C項：冰蓋上的雪很厚；D項：冰蓋上的雪很軟。通讀全文可知，文章沒有提到南極的天氣變化異常。故選A。
