一道英语题～～帮帮忙～～

1．Fred,who had expected how it would go with his daughter,had a great worry______his mind.
A on B in C with D at
答案为什么是A呢？不是be worry about么？

2 If there were no examinations,we should have____at school.
A the happiest time
B a more happier time
C much happiest time
D a much happier time
（答案是D）

Answer 1

worry是名词，此句中与后面的介词分开，on one‘s mind是固定搭配。
当有些不可数名词有定语修饰，就一定要加a/an，happy是形容词，要用副词much来修饰
