1.The boss____company I worked in two years ago has____in solving such kind of problem.
C 因为后面有名词company, 所以要选择一个作定语，那么whose. 其次是 experience 不可数 表示 经验，所以用much来修饰。

A.play;taking
used to do 过去常常做某事
be used to doing sth 习惯于做某事


3.____the first day of the school,she met her new teacher____the first time.
C.On;for

在开学的第一天，是个具体的日子，用on
for the first time 是第一次


4.____the whole schoolsafer and more pleasant is an important part of school development.

C.Making

其他三种都不能作主语

D.achieve;please

please sb 使某人高兴
