4. contains改為contain。主謂一致錯誤。主語programs為復數形式。

1. easier前加is。此處應構成“主語+系動詞+表語”句型。

10. 刪去it。此句中已有賓語your names， 不需用it。

　　 答案及解析

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

8. Those后加who。此處用who引導定語從句。

7. Someone改為Everyone。everyone側重整體， 指“每個人”； someone側重個體， 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共同構成謂語部分。
