Answer 1

____time, he'll make a first-class tennis player.
A. Having given
B. To give
C. Giving
D. Given
==>选C。
这里的___ time相当于条件从句，时态应该是一般现在时，排除A(相当于完成时)，B(相当于将来时)。这里虽然有被动意义，但不能用D。因为给时间在英语中约定俗成用giving time，而非given time。是个特例，记住就行。

它也并非独立主格：独立主格是指含有主语的独立状语，并非主动被动的问题：
（一）： 独立主格结构的构成：
名词(代词)+现在分词、过去分词；
名词(代词)+形容词；
名词(代词)+副词；
名词(代词)+不定式；
名词(代词) +介词短语构成。
（二） 独立主格结构的特点：
1）独立主格结构的逻辑主语与句子的主语不同，它独立存在。
2）名词或代词与后面的分词，形容词，副词，不定 式，介词等是主谓关系。
3）独立主格结构一般有逗号与主句分开。
举例：
The test finished, we began our holiday.
= When the test was finished, we began our holiday.
考试结束了，我们开始放假。
The president assassinated, the whole country was in deep sorrow.
= After the president was assassinated, the whole country was in deep sorrow.
总统被谋杀了，举国上下沉浸在悲哀之中。
Weather permitting, we are going to visit you tomorrow.
如果天气允许，我们明天去看你。
This done, we went home.
工作完成后，我们才回家。
The meeting gone over, everyone tired to go home earlier.
会议结束后，每个人都想早点回家。
He came into the room, his ears red with cold.
他回到了房子里，耳朵冻坏了。
He came out of the library, a large book under his arm.
他夹着本厚书，走出了图书馆

Answer 2

选D。
____time, he'll make a first-class tennis player.
只要给他时间，他将成为顶级网球手。

这是省略句,完整的是：
=If he is given time, he'll make a fisrt-class tennis player.

如果选B和C，就是主动语态。。意思是：他给别人时间。。
A.也不合适，，后面的主句是将来时，，所以从句用一般现在时的被动语态就可。
