In the 1980s, plastic shopping bags were everywhere, but
only a few
1
people realized they were causing serious environmental problems. Most of these bags
were made of
2
thin plastic—they broke easily, and many ended up in rivers or forests, harming wildlife.
Environmentalists
had difficulties in
3
making the public care about this issue. Many shoppers were used to free plastic bags and didn't want to change their habits.
Because of
4
this difficulty, a young designer named Anna came up with an idea:create a reusable shopping bag that was strong, cheap, and attractive.
Anna believed her idea could
stand up
5
and make a difference. She first
carried out
6
a small test in her neighbourhood:she gave 50 cotton bags to local shoppers and asked for feedback. The result was great—90% of shoppers said they would use the bag again. This positive feedback soon
resulted in
7
the mass production of reusable cotton bags.
The first widely used reusable shopping bag
was invented by
8
Anna in 1995. It wasn't just a simple
piece of
9
cloth—it had colourful patterns of flowers and animals, making it popular among all ages.
Today, reusable bags are common in stores around the world. Many shops even
are responsible for
10
encouraging customers to use them, like offering small discounts for bringing their own bags. Anna's story shows that a simple idea, when put into action, can solve big problems.

【分析】
本题为选词填空完成短文题型,解题思路如下:①先明确方框内所有短语的含义、用法及变形规则(如动词的时态、被动语态,介词短语的搭配等);②通读全文,把握每段的语境逻辑(如因果关系、动作先后等);③结合句子的语法结构(如主谓一致、时态要求、固定搭配),筛选恰当短语并调整为正确形式;④最后代入检查,确保短文通顺合理。
【解析】
1. 空1:前文提到20世纪80年代塑料购物袋随处可见,后文转折说明人们意识到环境问题,此处表示“只有少数人”,选短语only a few,符合语境。
2. 空2:句子主语为复数bags,表达“由薄塑料制成”,需用一般过去时的被动语态,故填were made of。
3. 空3:固定搭配have difficulties in doing sth.(做某事有困难),结合上下文过去时态,填had difficulties in。
4. 空4:此处表示“因为这个困难”,后接名词短语this difficulty,用介词短语Because of,符合逻辑。
5. 空5:情态动词could后接动词原形,stand up在此处意为“站得住脚,合理”,符合语境,填stand up。
6. 空6:表示“开展小测试”,短语carry out(实施、开展),结合过去时态,填carried out。
7. 空7:表示“积极反馈导致大规模生产”,短语result in(导致),过去式,填resulted in。
8. 空8:主语为the first widely used reusable shopping bag,是动作invent的承受者,需用一般过去时的被动语态,故填was invented by。
9. 空9:表示“一块布”,短语a piece of,填piece of。
10. 空10:主语为复数shops,表达“负责鼓励顾客”,一般现在时,故填are responsible for。
【答案】
1. only a few 2. were made of 3. had difficulties in 4. Because of 5. stand up 6. carried out 7. resulted in 8. was invented by 9. piece of 10. are responsible for
