Washing machines are heavy. That’s 1 there’s an average of 25kg of concrete inside them to stop them moving around when they’re on a spin cycle. And that means they’re not only difficult 2 (move) around in your home, they also cost a lot to transport.

3 all this could be about to change, thanks to a simple 4 (invent) by a team at the UK’s Nottingham Trent University.

Professor Amin hit on the 5 (brilliant) simple idea of replacing some of the concrete with 6sealable plastic container which can be filled with water once the machine is in place. 7 doing this, the weight of a washing machine can 8 (cut) by a third. In the UK alone, this could mean a saving of around 45,000 tonnes (公噸) of carbon dioxide emissions a year when the machines are transported, 9 is really a piece of good news to the environment.

“Everyone thinks the idea must have been thought of before,” says Dylan Knight. “No one can really believe it. But it will definitely work when 10 (put) into use.”

【解析】

這是一篇說明文。主要說明了洗衣機內(nèi)有一塊25公斤重的混凝土保證洗衣機旋轉(zhuǎn)時不亂動,但搬家時搬動洗衣機要花不少運費,最近英國的一個教授發(fā)明了新方法,用可以裝水的容器固定洗衣機的重心,從而解決了洗衣機搬運的問題。

1考查固定句式。句意:這是因為當它們旋轉(zhuǎn)時,里面有一塊25公斤的混凝土來阻止它們亂移動。固定句式that is because…“這是因為……”本句為表語從句,故填because。

2考查固定短語。句意:這意味著它們不僅在你家里很難移動,而且運輸成本也很高。固定短語be difficult to do sth.“做某事很難”,故填to move

3考查連詞。句意:不過,多虧了英國諾丁漢特倫特大學一個研究小組的一項簡單發(fā)明,這一切可能即將改變。結(jié)合上下文語境可知為轉(zhuǎn)折關系,故用but。故填But

4考查名詞。句意同上。結(jié)合上文a simple可知應填單數(shù)名詞。故填invention。

5考查副詞。句意: 阿明教授想出了一個絕妙而簡單的主意,用一個可密封的塑料容器來代替一些混凝土,一旦機器就位,這個塑料容器就可以裝滿水。simple為形容詞需要副詞修飾,故填brilliantly。

6考查冠詞。container為可數(shù)名詞,此處表示泛指“一個容器”,且sealable為輔音音素開頭的單詞,故填a。

7考查介詞。句意:通過這么做,洗衣機的重量可以減少三分之一。結(jié)合句意“通過”以及下文doing可知應填介詞by。故填By。

8考查動詞時態(tài)語態(tài)。句意同上。本句主語與謂語動詞構(gòu)成被動關系,且can后跟動詞原形,故填be cut

9考查定語從句關系詞。句意:僅在英國,這就意味著在運輸機器時,每年可以減少大約45000噸的二氧化碳排放,這對環(huán)境來說真是個好消息。本句為非限定性定語從句修飾上文整個句子,且從句缺少主語,故用關系代詞which。故填which。

10考查省略句。句意:但當投入使用時,它肯定會起作用。在when連詞連接的狀語從句中,常省略跟主句相同的主語和be動詞。從句完整為when (it was)put into use。故填put。

定語從句的關系詞的選擇可考慮以下三點:

(1)一看先行詞的意義,即分清先行詞是指人、指物、時間、地點還是原因(如指物時不能用whowhom,指人時通常不用which)

(2)二看關系詞的句法功能,即分清關系詞是擔任什么句子成分,是作主語還是賓語、是作定語還是狀語等(如作定語通常用whose,有時也用which;作狀語要用when, where, why)

(3)三看定語從句的種類,即分清是限制性定語從句還是非限制性定語從句(thatwhy通常不引導非限制性定語從句)

如第九小題,句意:僅在英國,這就意味著在運輸機器時,每年可以減少大約45000噸的二氧化碳排放,這對環(huán)境來說真是個好消息。本句為非限定性定語從句修飾上文整個句子,且從句缺少主語,故用關系代詞which。故填which。

In two days, it will be Christmas, children all over world 1 (look) forward to this day for weeks. People celebrate Christmas with food, decorations, music and more. But for many people, gift-giving is the most exciting part of the holiday.

Gift-giving reflects the reason 8 people celebrate Christmas. Christians in particular remember the birth of Jesus.
