8.The Pengs（一家人） ——be动词用is or are？
算单数还是复数？

Answer 1

1 B what an
what 后面需要加冠词，amazing又是a开头，所以用an
如果是how，则是how amazing the news is
2 D work out a question solve a problem
固定搭配
3 A 对于……来说，这个事情很真，只能用for
for somebody 对于……来说
sth of somebody somebody 的东西 从属关系
to 一般不用， 对于人一般都用for
from somebody 来自…… 如 learn from somebody 从……身上学习
4 B A没有for
并且习惯说法是which to choose 不是 to choose which
一般item只能用which，因为已经确定了是item这种东西，哪一个的意思，what只能用在不确定的东西上，是什么的意思，如what to eat，which country
6 C set out 出发 got up 起床 arrived 到达 started 只能用作 started the journey, 不能单独表出发 went 走 可以表示
7 B amazed 惊奇，只有surprise含吃惊的意思
sb is surprised at sth
sb is surprised to do sth
to one's surprise
in surprise
be surprised that
