2. about后加it。about是介詞， 后面應(yīng)接名詞、 代詞、 動名詞作賓語�！�

　　 答案及解析

9. go改為come。根據(jù)文章第一句話可知， 此通知發(fā)出者是the Students’ Union。所以要用come而不用go。

8. Those后加who。此處用who引導(dǎo)定語從句。

7. Someone改為Everyone。everyone側(cè)重整體， 指“每個人”； someone側(cè)重個體， 意為“某個人”。

6. 此行無錯。

5. begins改為begin。will后需用動詞原形與will共同構(gòu)成謂語部分。
