2. The situation seemed quite encouraging. 3. Your sentence doesn't sound right.
4. She appeared quite touched at the words. 5. It tastes sweet.

句型［主句+as if/as though+从句（主语+虚拟式谓语）］

3. It almost seemed as if the good man were trying to teach us all he knew at this last lesson.
4. …his exposed throat looked as if a halter would have done it good.
[注] 在as if 后面可以直接跟不定式，这是一种间缩的用法，如：He opened his lips as if to say something.
其次，在as if后面的谓语动词也有人用现在时的，如：It looks as if our side is (或were) going to win.
句型［主语+may (+not)+be+表语+虚拟式谓语）］［Perhaps等副词+主语+谓语+其他］
1. It may (not) be true. 2. "This fellow" he thought, "may not be a scamp…"
3. What month is this?-Maybe it's July. 4. Perhaps you are right.
5. Perhaps she is ill. 6. It will probably be fine tomorrow. 7. Possibly it is true.

6. It isn't a very good suggestion, to say the least of it.
[注] 有两个词组容易与as it were混淆，就是as it is, as it was。这两个词组必须用在和它们的时态一致的句中。意思是"照现在的样子"，"照当时的样子"，但都引申译为"事实上"，如：It is impossible to carry out the plan as it is.
