课后巩固提升
Ⅰ.1.C 2.D 3.A
4．A population作主语时，谓语动词用单数形式。句意：中国的人口大约是13亿。
5．A
6．D 本句中没有动作的执行者，所以用被动语态；主语是复数，所以be动词用复数，故选D。
7．C 考查little，few，much和many的比较级的用法。根据句意和实际情况，人口变得更多，所以第一空选择larger；而用于种植水稻的土地和水却更少，所以第二空选择less，故选C。
8．D increase to表示“(数量)增加到……”； increase by后接倍数或分数。题干中空线后是具体的数词，故选D。
9．B 当billion, thousand和hundred前有具体数字修饰时，不用复数形式；只有在百位和十位之间用and连接；个位与十位之间用连字符，故选B。
10．C 考查被动语态的用法。句意：12岁以下的孩子们不应该被允许骑共享单车。太危险了。根据语境可知应用allow的被动语态形式，be allowed to do sth.意为“被允许做某事”。故选C。
Ⅱ.1.by the weekend
2．in total
3．second largest
4．covered with
