[A] which [B] where [C] when [D] that 答案：A D C 我的错误答案：D C B

Answer 1

1.第一题错到D上面，说明问题在于时态的把握。
从前面的“.As
I’ll
be
away
for
at
least
a
year”（我将离开至少一年)看出，时态发生在将来，因此不用having
done而直接doing即可
2.这一空是spend
time
doing
sth.的被动
time
(which
was)
spent
doing
sth.
那么这一空填入动词的-ing形式即可。
你填一个完成时(having
done）进去是没有道理的
如果要用have表达，那么having
a
sunbathe=
sunbathing，
3.这里是when一个特殊的用法，表示在一个事情、状态持续的过程中，突然发生另一件事情，引导的仍是一个时间状语从句。
where引导的一直是地点状语从句，而后面的“我注意到一个年轻人举着"Boston"的牌子”显然不是在形容、描述一个地点，所以排除这个选项
