1. Students are encouraged to take active part in discussion.

Answer 1

1. a改为an；

2. such改为so；

3. them改为which；

4. have found改为have been found；

5. amazing改为amazed。

解析:

1. take an active part in，part前加有形容词，需要一个不定冠词来限制。

2. such改为so，helpful是形容词，需要so来修饰。

3. them改为which，逗号后面部分为非限定性定语从句。

4. have been found，这些新运用肯定不能是自己发现的，而是被发现的。

5. amazed，感到惊奇的。
