课时作业42

Ⅰ.完形填空

In my 40s, as a new solo (独自的) traveller, I spent endless time looking around souvenir shops in tourist areas. It never __1__ me that in shops where merchants weren't __2__ big rents, I could save more money. Besides, I didn't give much __3__ for the size of what I was buying, nor did I care that I would have to take the __4__ to carry it around for the duration of my holidays.

I learned and __5__. But I also found that over time, the objects that were __6__ to me changed too. As my tastes matured, my bags got __7__, and so did the time I spent buying cheap goods.

In my 50s I __8__ boxes from around the world. Not ordinary boxes but ones __9__ made by artists. These were small so they __10__ easily into every place of my backpack. The __11__ was delightful—the silver from South Korea, the painted camel bone from Egypt and dozens more took up their __12__ in my house.

Then a __13__ thing happened. My interest in the collection __14__ while my grandchildren's interest in it grew, so a wonderful and new __15__ began. Each time a child came to visit, he or she was __16__ to pick a box. My popularity __17__ increased among the children, and pretty soon my collection had been __18__ among the little people in our family. Each gift was __19__ by a minitravel story explaining where the __20__ was found, who had made it and what that country was like.

本文是一篇记叙文。作者讲述了自己对旅游纪念品的兴趣变化,间接地描述着自己生活的变化。

1.A.counted on C.called on 答案:B

解析:根据第一句话中的“我在旅游地花大量时间逛纪念品店”以及下文中的“for the size of what I was buying”可知,此处表示“我从没有想过在商家不用一直付大笔租金的店买东西(纪念品),那样会省下更多的钱”。故答案为B。dawn on“使开始明白,使渐渐领悟,使开始理解”,符合语境。count on“依靠,指望”;call on“呼吁,短暂访问”;concentrate on“把注意力集中于”。

2.A.lending C.purchasing 答案:D

解析:参见上题解析。rent表示“租金”,故此处应用paying。pay the rent“支付租金”。

3.A.advice C.concern

B.anxiety D.support B.investing D.paying B.dawned on D.concentrated on

答案:C

解析:承接上文中的“It never...money”以及“Besides, I didn't”可判断此处表示“而且我没有怎么关注所买东西的大小,我也不在乎要在整个旅游期间费力带着所买的东西周游”,故选concern“关切,担心”。

4.A.trouble C.chance 答案:A

解析:参见上题解析。take the trouble to do sth.“费力做某事”。 5.A.applied C.judged 答案:B

解析:根据learned和后一句“But I also found that over time, the objects...changed too”可知,作者不断学习和适应(adjusted)。

6.A.accessible C.shiny 答案:B

解析:根据语境和下文中的“As my tastes matured”可知,此处表示“随着时间的推移,吸引我的东西也变了”。所以答案为appealing“吸引人的,信人感兴趣的”。

7.A.smaller C.heavier 答案:A

解析:根据上文中的“As my tastes matured”可知,随着作者兴趣逐渐成熟,作者对纪念品自然就有所选择,所以“我的背包越来越小了,我花在买便宜物品上的时间也越来越少了”。

8.A.designed C.collected 答案:C

解析:表示收集盒子应用collect。 9.A.lovingly C.carelessly 答案:A

解析:本空与ordinary呼应,既然不是普通的,那就应是艺术家精心制作的。lovingly“精心地”符合语境。

10.A.cut C.set 答案:D

解析:这些盒子小巧玲珑,因此很容易装进背包的任意一个地方。表示大小合适,应用fit。

11.A.value

B.pattern B.got D.fitted B.intentionally D.ambitiously B.discovered D.received B.bigger D.smarter B.appealing D.disappointing B.adjusted D.checked B.way D.lead

C.fashion 答案:D

D.variety

解析:根据破折号后面所列举的例子可知,此处应是说明这些盒子丰富多样、令人高兴。 12.A.role C.duty 答案:B

解析:此处表示“还有很多在我的房子里,它们都有各自的一席之地”,故用position。 13.A.strange C.terrible 答案:D

解析:本段描述作者对收藏品的兴趣逐渐消失,而作者的孙辈们对收藏品的兴趣却越来越浓,所以这算是一件有趣的(funny)事。

14.A.grew C.faded 答案:C

解析:根据本段内容以及连词while表转折意义可知,空处应与grew形成对比,应选faded“逐渐消失”。

15.A.routine C.journey 答案:A

解析:根据上文提到作者的孙辈们对作者的收藏品越来越感兴趣和下文中的“Each time a child came to visit, he or she was __16__ to pick a box”可知,一个美妙的新习惯开始了。routine在这里表示“常规,习惯”。

16.A.forbidden C.advocated 答案:B

解析:每当有孩子来,他或她都被允许选一个盒子。 17.A.normally C.fortunately 答案:D

解析:随着孩子们的到来,作者收藏的盒子日益受欢迎,而作者也越来越受欢迎,这是作者感到开心的一点,故选delightfully“令人愉快地”。

18.A.exposed C.divided 答案:C

解析:很快作者的收藏品就被孩子们分完了,所以选divided“分享,分配”。 19.A.accompanied C.described 答案:A

B.clarified D.confirmed B.awarded D.exchanged B.casually D.delightfully B.allowed D.promoted B.hobby D.principle B.changed D.rose B.vital D.funny B.position D.time

解析:根据语境判断,每一份礼物(即盒子)都伴随着一段旅游小故事,解释了它被发现的地方和制作者以及那个国家的情况。accompany用作及物动词,表示“伴随,陪伴,陪同”,符合语境。

20.A.article C.box 答案:C

解析:参见上题解析,应选box。 Ⅱ.七选五

Fabric softener (织物柔顺剂) is a product used in clothes washing in order to make clothes soft. __1__ Many people argued that this was a completely unnecessary product that just polluted our surroundings. However, these days, there's attractive fabric softener that is environmentally friendly.

__2__ For example, it reduces static cling (静电吸附). After using it, socks don't stick to sweaters when they're taken out of the dryer and all who touch you won't receive an electric shock. It also reduces wrinkles in clothes. Some materials will still have to be ironed, but using a little fabric softener will help reduce the amount of wrinkles produced after the materials are washed.

Allergy-prone (易于过敏的) people or those with sensitive skin may have problems, when using fabric softener. The allergic reaction might be due to the chemicals giving the product a kind of fragrance. __3__ There are also organic (有机的) products on the market. If fabric softener simply cannot be used, vinegar can be used to make clothes softer and remove some of the static.

There're different fabric softener products on the market today. __4__ Many people have their favorites, but truthfully, one brand is not necessarily better than another. Choose the brand in your price range with a fragrance you enjoy, or no fragrance at all. Use the “trial and error” to see if one brand works better for your family's needs than another. __5__ The soft feel of your clothes and the removing of static cling are the most important.

A.It was considered to be a great invention. B.There're many benefits of using a fabric softener. C.Once the product was not popular with the public. D.Many busy housekeepers dislike tasks like ironing. E.They come in many different sizes and price ranges. F.You'll find, in most cases, that brand doesn't matter. G.If this is the case, a non-fragrant one might be preferable. 本文是一篇说明文,介绍了织物柔顺剂的作用和种类。

1.C 解析:该项位于段中,与下文Many people argued that...surroundings.形成逻辑上的解释说明关系:下文解释了人们不喜欢柔顺剂的原因。

2.B 解析:该项位于段首,是本段的主旨句。通读本段可知本段主要陈述的是织物柔

B.story D.backpack

顺剂的优点。

3.G 解析:该项位于段中,与下文形成指代关系。该项中的the case指代的是前文提到的内容:过敏是由于柔顺剂中能给织物添加芳香的化学物质。

4.E 解析:该项位于段中,与上文形成逻辑上的指代关系,该项中的they指代上文的different fabric softener products。

5.F 解析:该项位于段中,与上文Use trial...another.形成逻辑上的顺承关系,与下文The soft feel...most important形成转折关系。

Ⅲ.短文改错

On my first day in high school, I meet my deskmate. She was the first person I got to knowing in the school and I counted on her great.

She was warm-hearted and helped me get familiar to the new environment. The quality which impressed me most were her determination. When we worked together, I wanted to give up the task sometimes because I found out it difficult. However, my deskmate always encouraged myself to carry on. At last, we solved all the problem through our efforts. That she taught me still affects me now.

I'm lucky enough to make friends with so nice person. May our friendship last forever.
