高中英语上学期第7周周练题(无答案)

四川省宜宾市一中2018-2019学年高中英语上学期第7周周练题第一部分阅读理解（共两节，满分40分）第一节（共7小题；每小题2分，满分14分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。 A Every one of us has been hurt by others – either by their words or actions. In those moments, you may feel so much anger that you want to hurt the other person too. But we all know that revenge(报复) doesn’t get us anywhere. So, in order to live a happy life, the best way to deal with the problem is, perhaps, as the old saying goes, to “forgive and forget”. The wisdom of this saying has even been proven in scientific studies. “It is well established that learning to forgive others can have positive benefits for one’s physical and mental Health,”Saima Noreen, a scientist at the University of St Andrews, Uk, told the Huffington Post. And now, Noreen and her research team may have found one more reason that you should stick to this principle – forgiving somebody who has hurt you makes it easier for you to forget the unhappy memory, according to their new study. In the study, researchers asked volunteers to read descriptions of 40 different situations that contained bad actions such as stealing, lying and cheating.
