【题目】阅读下面材料,在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

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 (公吨) 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.”

【答案】

1because

2to move

3But

4invention

5brilliantly

6a

7By

8be cut

9which

10put

【解析】

这是一篇说明文。主要说明了洗衣机内有一块25公斤重的混凝土保证洗衣机旋转时不乱动,但搬家时搬动洗衣机要花不少运费,最近英国的一个教授发明了新方法,用可以装水的容器固定洗衣机的重心,从而解决了洗衣机搬运的问题。

1考查固定句式。句意:这是因为当它们旋转时,里面有一块25公斤的混凝土来阻止它们乱移动。固定句式that is because…“这是因为……”本句为表语从句,故填because

2考查固定短语。句意:这意味着它们不仅在你家里很难移动,而且运输成本也很高。固定短语be difficult to do sth.“做某事很难”,故填to move

3考查连词。句意:不过,多亏了英国诺丁汉特伦特大学一个研究小组的一项简单发明,这一切可能即将改变。结合上下文语境可知为转折关系,故用but。故填But

4考查名词。句意同上。结合上文a simple可知应填单数名词。故填invention

5考查副词。句意: 阿明教授想出了一个绝妙而简单的主意,用一个可密封的塑料容器来代替一些混凝土,一旦机器就位,这个塑料容器就可以装满水。simple为形容词需要副词修饰,故填brilliantly

6考查冠词。container为可数名词,此处表示泛指“一个容器”,且sealable为辅音音素开头的单词,故填a

7考查介词。句意:通过这么做,洗衣机的重量可以减少三分之一。结合句意“通过”以及下文doing可知应填介词by。故填By

8考查动词时态语态。句意同上。本句主语与谓语动词构成被动关系,且can后跟动词原形,故填be cut

9考查定语从句关系词。句意:仅在英国,这就意味着在运输机器时,每年可以减少大约45000吨的二氧化碳排放,这对环境来说真是个好消息。本句为非限定性定语从句修饰上文整个句子,且从句缺少主语,故用关系代词which。故填which

10考查省略句。句意:但当投入使用时,它肯定会起作用。在when连词连接的状语从句中,常省略跟主句相同的主语和be动词。从句完整为when (it was)put into use。故填put

定语从句的关系词的选择可考虑以下三点:

(1)一看先行词的意义,即分清先行词是指人、指物、时间、地点还是原因(如指物时不能用whowhom,指人时通常不用which)

(2)二看关系词的句法功能,即分清关系词是担任什么句子成分,是作主语还是宾语、是作定语还是状语等(如作定语通常用whose,有时也用which;作状语要用when, where, why)

(3)三看定语从句的种类,即分清是限制性定语从句还是非限制性定语从句(thatwhy通常不引导非限制性定语从句)

如第九小题,句意:仅在英国,这就意味着在运输机器时,每年可以减少大约45000吨的二氧化碳排放,这对环境来说真是个好消息。本句为非限定性定语从句修饰上文整个句子,且从句缺少主语,故用关系代词which。故填which

【题目】Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

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.

I have found memories of Christmas shopping with my family as a child. I enjoyed the challenge of keeping my parents’ gifts a secret. It was hard to buy gifts right. 2 their noses without them seeing. Everyone placed 3 (wrap) gifts under the Christmas tree until Christmas morning, 4 we opened them.

Picking a great gift require 5 (know) the person you’re giving it to. You need to know the person’s tastes and find something the person doesn’t already have. This can be quite a big challenge. Often it’s wise to provide a receipt 6 the person needs to exchange the gift.

The best gifts are personal. Many Americans don’t feel money constitutes a good gift 7 it doesn’t require any thought. They prefer something chosen just for the person. If the gift is a high-quality homemade gift, that’s even better.

Gift-giving reflects the reason 8 people celebrate Christmas. Christians in particular remember the birth of Jesus. When he was born, wise men traveled many miles to visit him, 9 (bring) expensive gifts. But the greatest gift wasn’t from the wise man, but from God—the baby Jesus. God gave this gift because everyone needed it. We needed God to forgive our bad actions so that we 10 live forever with him. So on Christmas we give presents to imitate God’s action of giving the perfect gift.
