I think it's our duty to protect our environment We should save the water and turn off the light when we leave the room We shouldn't use plastic bags We'd better ride a bike or walk instead of taking a car We should pick up the rubbish and throw it into the dustbin I believe if everyone makes a contribution to the environment, our world will become more and more beautiful

's是表示所有格关系，一般译为 的。

当名词是人名，或表示有生命以及被视为有生命的东西的时候，可以用一个撇号“’”+s（Apostrophe +s）来表示所有格（Possessive Case）关系。有以下几点值得注意：

1) 名词+’s。例如：

John’s property约翰的财产

2) 以-s结尾的名词复数+’。例如：

the workers’ library工人的图书馆

但不以-s结尾的名词复数形式仍须加’s，例如：

the children’s palace 少年宫

3) 以-s结尾的专有名词或普通名词可用’s，也可只用“’”。例如：

Dickens’(s) novels狄更斯的小说

4) 如某物为两人所共有，只需在这两个名词后加“’s”。例如：

Mary and Jane’s car （她俩共有的车）

否则，需要在这两个名词后分别加上“’s”。例如：

Mary’s and Jane’s cars （她俩各自的车）

注表示国家、城市等地方的名词，以及表示时间、距离、度量及金钱等的名词，虽是无生命的，但是也可用以上形式，表示所有或修饰关系。例如：

China’s modernization plan 中国的现代化计划

a two weeks’ holiday 一个两周的假期

a dollar’s worth of apples 一元钱的苹果

选A啊

“in + 一段时间”表示那一段时间之后，固定用法：比如一个小时时候 in an hour

题干中有一个“a”表示是一个单数啊，所以week不用复数形式

's 表示所有格 ，什么什么的 a week's time 一个星期的时间

in a week's time 表示一个星期之后
