1. Students are encouraged to take active part in discussion.
2. The boy is such helpful that we all think highly of him.
3. Elizabeth has many postcards, all of them were bought in London.
4. Since the 1970s many new applications have found for the computer.

Answer 1

1. a改為an；
2. such改為so；
3. them改為which；
4. have found改為have been found；
5. amazing改為amazed。

1. take an active part in，part前加有形容詞，需要一個(gè)不定冠詞來(lái)限制。
2. such改為so，helpful是形容詞，需要so來(lái)修飾。
3. them改為which，逗號(hào)后面部分為非限定性定語(yǔ)從句。
4. have been found，這些新運(yùn)用肯定不能是自己發(fā)現(xiàn)的，而是被發(fā)現(xiàn)的。
5. amazed，感到驚奇的。
