人教修订版高一英语Unit 16课堂练习4
7（）Tom _____ into the house when no one _____.
A. slipped, was looking B. had slipped, looked
C. slipped , looked D. was slipping , looked
参考答案为A.
译：汤姆在没有注意时,偷偷溜进了房子.
注意到了吗?我将look译成了“注意".
可以有人认为这个look应该为notice, 这个词一般记作“注意”,是吧?
但是其实notice是注意到,和see看到,hear听到一样,是没有进行时态的.
这一题选哪一个都不爽!
我想改一下：Tom slipped into the house without being noticed.
查《美国传统双解》notice只有及物用法：
v.tr.（及物动词）
1.To take notice of; observe:
注意…；发觉：noticed a figure in the doorway.See Synonyms at &b{see} &+{1}注意到门廊上的人影参见 see1
2.To perceive with the mind; detect:
用心观察；侦查：noticed several discrepancies.注意以几处不符
3.To comment on; mention.
评论…；提及
4.To treat with courteous attention.
关注：尊敬地对待
5.To give or file a notice of:
被警告或通知：
noticed the court case for next Tuesday.被通知出席下周二的法庭审理
查《21世纪》有不及物用法,但受限类似于：I don't know的情况一样：
注意,留意,发觉
"Was she there?"- "I didn't ~.".
「她在那裏吗?」「我没有留意」
本题中的notice替换了look,不当.notice没宾语,不用于进行时态.
