要详细解答过程

Answer 1

1——what's the matter?——there are several types of tv sets__,but i'm at a loss which to buy.
A.to be chosen Bto choosefrom
答案：B
[解析]动词不定式作定语，当其被修饰的词表示不定式动作发生的场所、所借助的工具等时，不定式后需带相应的介词。本题中 TV sets便是 choose发生的场所，意为“从……中选”，故应带介词from.
2——You should have thanked the woman who had helped you before you left.
——I meant__,but when i was leaving i couldn"t find her anywhere.
A.to do B.to C.doing D.dong it
答案：B
[解析]该题考查动词不定式的省略。当动词不定式指代前文中所说的相同动作时，可以将动词省掉而只保留不定符号to, 但当to后为have或be时，have和be均不能省略。本题中不定式代前文所说的 thank，故省略。

Answer 2

B 一定要有from，因为从好多种电视机里挑，choose这里用主动被动都可以。
B 省略了后面的do sth.
meant to do sth, 固定搭配，表示想要做什么来的。
