解答此类单词拼写题,需先根据中文提示确定对应英文单词,再结合句子结构(如名词单复数、动词形式)判断正确形式:1. 由“all”可知后接可数名词复数,对应“人物”的英文;2. 主语为复数名词“people”,一般现在时中动词用原形,对应“预料;期待”的动词;3. 与前面的“do”并列,需用动词原形,对应“交换”的英文。
【解析】
1. 句意:这本书里所有的人物都容易记住。“人物”的英文是名词character,all后接可数名词复数,故填characters;
2. 句意:这部电影如此受欢迎,以至于人们期待它成为今年最好的电影之一。“预料;期待”的英文是动词expect,主语people为复数,一般现在时中动词用原形,故填expect;
3. 句意:很多国家将有更多做生意的机会,也会交换想法。“交换”的英文是动词exchange,与前面的do并列,需用动词原形,故填exchange。

【分析】
这是一组英语语法填空题,需结合句子结构、固定搭配、时态规则、词形变化等知识点解题。具体思路:1. 根据修饰词(如one hundred、many)判断名词单复数;2. 依据固定搭配(如expect sb to do sth、make a difference)确定非谓语或名词形式;3. 由比较级标志词than确定形容词/副词的比较级;4. 根据时间状语(如yesterday相关)确定动词的过去式;5. 结合祈使句、定语从句的语法规则判断动词形式。
【解析】
4. 空格前为one hundred,后接可数名词复数,故将metre变为复数metres;
5. 固定搭配expect sb to do sth要求此处用动词不定式,故填to look;
6. 固定短语make a difference中需名词,different的名词形式为difference,故填difference;
7. 句中出现比较级标志词than,well的比较级是better,故填better;
8. 空格前为many,后接可数名词复数,similar的名词是similarity,复数为similarities,故填similarities;
9. different后接可数名词复数,故将situation变为situations,填situations;
10. 时间状语为yesterday afternoon,表过去,故用reach的过去式reached;
11. 否定祈使句结构为Don't + 动词原形,故填touch;
12. 时间状语为yesterday's meeting,表过去,故用exchange的过去式exchanged;
13. 定语从句先行词是those(复数),谓语动词用原形,故填care;
14. similar后接名词,personal的名词是personality,此处指多人的性格,用复数personalities,故填personalities;
【答案】
4. metres;5. to look;6. difference;7. better;8. similarities;9. situations;10. reached;11. touch;12. exchanged;13. care;14. personalities

四 任务型阅读
阅读下面材料,从方框中所给的 A—E 五个选项中选出正确选项(其中一项是多余选项),将其序号填入第 20—23 小题,并回答第 24 小题。
Close friends, think alike?
“What! You too? I believed I was the only one.” Have you ever said something like this to someone?
20.
B

It seems that similarity often helps develop friendship. The Greek thinker Aristotle once said, “ People regard friendship as a matter of similarity; they say that we love those who are like ourselves.” 21.
A
Scientists from University of California said friends have similar brains.
The scientists invited university students to take part in a test. Each student watched the same set of videos. At the same time, scientists scanned their brains and recorded their brain activity. According to their scans, friends who watched the same video reacted in similar ways. Similar parts of their brains lit up while watching the videos, especially the parts that were connected with motivation, learning and memory. 22.
E

“Seeing one’s friends have similar brains will reinforce(加强) one’s own values, opinions, and interests,” a scientist named Carolyn Parkinson told Business Insider. 23.
D

Scientists from the University of Leipzig, Germany, found that friendship is also based on how physically close you are to someone. The scientists did a test with first-year college students who they met in class for the first time. In this test, students who sat in neighbouring seats were more likely to become friends.

24. Besides brain similarity and physical closeness mentioned in the passage, what do you think is the most important factor in making friends? Give one example. (Answer within 15 words)

答案

20. B
21. A
22. E
23. D
24. I think trust between each other is the most important.(答案不唯一,言之有理即可)

解析

【分析】
做这类句子还原题,需结合上下文的逻辑关系(承接、转折等)选择选项:
1. 第20空:前文提到“你有没有说过类似‘你也这样?我以为只有我这样’的话?”,B选项承接该对话场景,说明这种情况可能发展成友谊,引出相似性助于友谊的话题,故20选B。
2. 第21空:前文引用亚里士多德的观点,后文提到科学研究,A选项衔接前文观点,说明该想法有科学依据,引出后文研究,故21选A。
3. 第22空:前文讲朋友看视频反应相似,E选项用“However”转折,对比非朋友的不同反应,故22选E。
4. 第23空:前文讲大脑相似是友谊因素,后文讲物理距离的因素,D选项承上启下,说明大脑相似不是唯一因素,故23选D。
5. 第24空:需结合文章提到的交友因素,给出合理的其他因素,言之有理即可。
【解析】
1. 20题:前文的对话场景对应B选项“you may have ended up becoming friends with this person”,符合逻辑,选B。
2. 21题:前文的观点需要科学支撑,A选项“there is some science behind this idea”衔接后文的科学研究,选A。
3. 22题:前文说朋友反应相似,E选项“However, people who weren't friends had different reactions”形成转折对比,选E。
4. 23题:前文讲大脑相似,后文讲物理距离,D选项“not the only thing that can bring friendship”承上启下,选D。
5. 24题:示例答案:I think trust between each other is the most important.(答案不唯一,合理即可)
【答案】
20. B;21. A;22. E;23. D;24. I think trust between each other is the most important.(答案不唯一,言之有理即可)
