A.to;withB.with;withC.with;toD.about;with
I'd like to buy my mother a birthday present,____that is cheap and useful.
A.itB.the oneC.oneD.which

Answer 1

C
be familiar with sth,对某物熟悉
be familiar to sb.对某人来说...不熟悉

C
后面的that is cheap and useful是一个定语从句，所以前面缺少一个名词或者代词作定语，我选one,指代前面的a birthday present。
I'd like to buy my mother a birthday present，one that is cheap and useful,意思是，我想买给我妈一件生日礼物，一件价格便宜又很有用的。

Answer 2

c d

Answer 3

C 你熟悉他们使用的MP4 游戏吗？对不起，我对它不熟悉。 be familiar with 熟悉
be familiar to sb.某人对......熟悉
B the one that is cheap and useful.
在这里做a birthday present的同位that is cheap and useful做定语，是定语从句，that是定语从句中的关系代词，修饰the one意思是又便宜又有用的生日礼物。，the 是定冠词，特指。

Answer 4

C

C

Answer 5

1. C; sb be familiar with sth 对某事熟悉; sth be familiar to sb 某事令

2. B; 定语从句，the one特指生日礼物，that引导句子。
