【解析】

【1】句意：重復(fù)使用購(gòu)物袋是減少污染的好方法。

根據(jù)“reduce pollution”減少污染，可知，應(yīng)該是重復(fù)使用購(gòu)物袋，這樣會(huì)減少污染。因此應(yīng)該填：reuse；分析句子的結(jié)構(gòu)可知，本題應(yīng)該是主語(yǔ)的位置；所給的單詞是動(dòng)詞，因此應(yīng)該用其動(dòng)名詞形式。首字母要大寫。故答案為：Reusing。

【2】句意：他們很難找到一個(gè)新的售貨員。

分析句子的結(jié)構(gòu)可知，本題應(yīng)該填一個(gè)名詞；difficult的名詞為difficulty。have difficulty in doing sth.：做某事有困難；又因?yàn)楸绢}的主語(yǔ)是They，因此該題的名詞應(yīng)該用復(fù)數(shù)形式。 故答案為：difficulties。

【3】句意：老師告訴我們需要另外兩個(gè)學(xué)生做圖書管理員。

由語(yǔ)境和所給的單詞可知，應(yīng)該填librarian；由本題的another two students另外兩個(gè)學(xué)生，可知，該題應(yīng)該填名詞的復(fù)數(shù)形式。故答案為：librarians。

【4】句意：這個(gè)文靜的人認(rèn)為在花園里工作是令人滿意的。

單詞satisfy 的形容詞有兩個(gè)：satisfied和satisfying。satisfied形容詞，句子中通常是人做主語(yǔ)；satisfying形容詞，令人滿足的，令人滿意的，通常物做主語(yǔ)。本題的主語(yǔ)是it，因此用形容詞satisfying。故答案為：satisfying。

【5】句意：總統(tǒng)將到墨西哥進(jìn)行為期四天的正式訪問。

由空后面的tour可知，前面應(yīng)該用形容詞來(lái)修飾，office的形容詞為official。official tour：正式訪問。故答案為：official。

【6】句意：熏肉的香味使我垂涎欲滴。

由空后面的smell of bacon（熏肉味）可知，前面應(yīng)該用形容詞來(lái)修飾，please的形容詞為pleasant。再根據(jù)“makes my mouth watering”垂涎欲滴�？芍�，前面應(yīng)該是指熏肉的香味。故答案為：pleasant。

【7】句意：我們學(xué)校的每個(gè)學(xué)生都禮貌地向老師打招呼。

由空前面的greets可知，greets是動(dòng)詞，后面應(yīng)該用副詞來(lái)修飾；polite的副詞為politely。故答案為：politely。

【8】句意：閱讀使我們的頭腦豐富了許多知識(shí)和各種新思想。

分析句子“Reading ________ our mind with a lot of knowledge and various new ideas.”的結(jié)構(gòu)可知，本題缺少謂語(yǔ)。enrich動(dòng)詞，“使富足，使肥沃”的意思。又因?yàn)楸绢}陳述的是一種客觀事實(shí)，因此應(yīng)該用一般現(xiàn)在時(shí)；主語(yǔ)是動(dòng)名詞Reading，因此謂語(yǔ)用三單形式。故答案為：enriches。

【題目】Hyperloop: the train of the future?

We’re going through the Nevada desert, north of Las Vegas, for having a look at what its supporters believe is the future of transport. This is Hyperloop - an attempt to send passengers rushing at 700 miles an hour through a vacuum tube.

Many think that’s impossible, but this project came back last year of virgin America Inc. with Sir Richard Branson becoming chari-man. In this 500-metre test track, they say they have shown that the technology works, though they’ve not yet put any human beings on board. The head of engineering, a space scientist from NASA, sees no reason why people might be frightened.

Anita Sengupta, Head of Engineering, Virgin Hyperloop One

“The Hyperloop is a maglev train in a vacuum system. And so you can also think of it as an aircraft flying at 200,000 feet high so people don’t have any problem flying in aeroplanes and people don’t have any problem going in maglev trains. This is simply joining the two and allows you to be more energy - saving.” The Virgin Hyperloop team have said they could take passengers from London to Edinburgh in 50 minutes or cut the journey between. New York and Boston to under half an hour.

Did you know?

The word ‘maglev’ is a combination（結(jié)合）of the words ‘magnetic’ and ‘levitation’. This is because the system uses magnets to levitate（使浮起）the train. This reduces friction（摩擦力）-- the force that makes it difficult for things to move freely when they are touching each other -- and increases speed. The first maglev train operated in Hamburg, Germany in 1979.

【1】You are likely to see Hyperloop in ________.

A.City of Las VegasB.Nevada DesertC.NASA BaseD.Hamburg, Germany

【2】Hyperloop didn’t get support until ________.

A.human beings were put on boardB.the vacuum tube was completed last year

C.Sir Richard Branson became chairmanD.scientists solved two problems of transport

【3】The underlined word “attempt”can be replaced by “________’.

A.effectB.effortC.eventD.example

【4】A maglev train is fast because it can ________.

A.rise to 200,000 feet highB.rush in a vacuum tube

C.float because of the magnetsD.reduce friction of the air

【5】Which of the following statement is TRUE?

A.Head of the Virgin Hyperloop Team is a space scientist.

B.The first maglev train was invented in the Untied States.

C.Most people have confidence in the Hyperloop project.

D.Hyperloop has sent passengers from New York to Boston.

【6】What is the Hyperloop? The Hyperloop is ________.

A.a vacuum tube testing a maglev train system

B.an aeroplane flying at 700miles an hour
