试题分析：

1. harmful to=do harm to=be bad for对……有害，此处需要一般现在时，故填is harmful to / does harm to / is bad for。

2. in doing sth.成功做某事，根据句意应该用一般过去时，故填succeeded in getting。

3. measures采取措施，根据句意应该用现在完成时，故填has taken measures。

4. contributions to sth/doing sth.为……做贡献，故填contributions to protecting。

5. 借，当在肯定句中与时间段连用时要改为延续性动词keep，根据句意应该用现在完成时，要故填has kept since。
