句式链接：

[句式分析]　likely常用于“Sb./Sth.＋be likely to do sth.”句型中，该句型常与“It＋be likely that..”互换。
Sb./Sth. is likely to do... 某人/某事有可能……
It is likely that... 有可能……

　他可能出席会议。
①_________________________________________________
②___________________________________________________
③____________________________________________
④___________________________________________
It is possible for him to attend the meeting.　
It is probable that he will attend the meeting.　
He is likely to attend the meeting.　
It is likely that he will attend the meeting.
易错词语辨析：
likely/possible/probable
likely表示某事很可能发生，与probable意思相近，但主语可以是人也可以是物。常用于“It is likely that...”或“Sb./Sth. be likely to do...”句型中，但不能说“It is likely for sb. to do sth.”。
possible可能性相对小，作表语时，主语不能是人，常用句式为“It is possible for sb. to do sth.”或“It is possible that...”。
probable带有“很可能”的意味，语气比possible强，作表语时不能用人或不定式作主语，常用句式为“It is probable that...”。
4.感叹句
(教材P109)How clever! 多聪明啊！
[句式分析]　本句是一个省略式的感叹句，其完整形式为“How clever you are！”。感叹句句型用来表示说话者的惊异、喜悦、沮丧等情绪。
