　　help＝very helpful "非常有帮助"。

　　10．________(take) according to the instructions, the medicine has no side effect.

　　Ⅱ.单句改错

　　____________________________________________________

　　答案：overlooking→overlooked　overlook与mistakes之间为逻辑上的动宾关系，故应用被动语态。

　　2．In term of education, I first thank all my teachers who have devoted themselves to their profession.

　　_____________________________________________________

　　答案：term→terms　in terms of "就......来说；从......角度"。

　　3．Fortunate, the fire was discovered soon after it had started.

　　_____________________________________________________

　　答案：Fortunate→Fortunately　副词作状语修饰整个句子，故应将fortunate改为fortunately。

　　4．The September 11 attack has condemned by the entire

　　international community.

　　_____________________________________________________

　　答案：has后加been　现在完成时的被动语态的构成：have been＋过去分词。9.11恐怖袭击应是"被谴责"，故应在has后加been。

　　5．When the interview was finished, I was shown in.

　　_____________________________________________________

　　答案：in→out　show sb. in "带某人进来"；show sb. out"带某人出去"。由句意可知后一短语符合语境。
