【问】It the boat would leave the danger of ice in thechannel. (TOEFL，71.3)

答案为A(应将looks改为seems)。难道it looks as though不是正确的格式吗?

【答】 it looks as if (as though)也是英语的正确用法，只是没有it seems as if(as though)用得那么正式。请看下面的实例：

1. It looks as if it's going to rain. (CCUD)

天好象要下雨。

2. It looks as if we're going to miss the plane. (LASED)

好象我们要赶不上飞机了。

3. It looks as if they are all in a terrible hurry.(Mis)

好象他们非常匆忙。

4. It looks as though we shall have to do the work ourselves. (Wood)

好象我们要自己做这项工作了。
