Answer 1

1.It is of vital importance that a person ___at least both physically and mentallynstrong to be an astronaut.
D.must be
一个人要至少身心强健才能去做宇航员，这一点至关重要。

2.___his speech than the audience began to ask him some difficult questions.
B.No sooner have the speaker finished
考察词组“no sooner…than”，这个结构需要倒装语序，意为“一……就”“刚……便”。句子意为“演讲者刚完成演说，观众便开始向他提出难题。”

3.The old lady ,with her seeing-eye dog ,___seen going along the street every morning.
A.was
考察主谓一致关系，主语The old lady为单数，插入成分with her seeing-eye dog为状语，不影响谓语的数。

4.In ESL teaching ,it is really hard to say which theory is __any of the others put forward so far.
B.obviously superior to
superior to，固定搭配，“比…优越(好)”，不用than。obviously为副词，修饰形容词superior，放在形容词前。

Answer 2

楼上回答基本正确，但第一题应该选A
shall可以表示说话人的语气（命令、威胁等）。
其实D语法当然没有错。
