6、“发现，查明，了解”，表示经过观察、调查把某事、某物查出、 搞清楚，多用于复杂而不易直接查出的情况。例如：I II try to find out who did this?我要设法弄清楚这是谁干的。（3） look for 作“寻找”解时，指寻找的动作和过程，是延续性动词。I m looking for a place for you to stay.我正在给你找住的地方。（4） discover 多指通过实验、调查、勘探等“发现、找到”未被发掘或认识的事 物。例如：Columbus discovered America.哥伦布发现了美洲。10、辨析:alone, lonelyalone表示

7、“独自一人（或仅几个人）”，多作表语；作后置定语时，表示“只有，仅仅”的意思。例如：The man lives alone.那位老人自己一个人住。Ion ely 既可以作定语也可以作表语；作定语时意思是“孤独的，偏僻的，荒凉的”； 作表语时表示“寂寞的，孤单的”。例如：When his family moved, Mark was Ion ely un til he made new frien ds.马克一家搬家后，在没有交上新朋友前他一直很寂寞。11、 Why dont you？是用来提出邀请、建议或对某人不愿做某事时提出的反问。它并不表示怀疑，而是有肯定的意义。在口语中，常常省略主语和谓

12、 it doesn t rain tomorrow, we ll go for a picnic. 如果明天不下雨，我们将去野餐。If he gets home early this evening, he will cook for us. 如果他今晚回来早，他将为我们做饭。If I am free this weekend, I will play basketball with my friends. 如果这个周末我有空，我将和朋友一起去打篮球。3、 If 在下面句子里的意思是“是否”，引导宾语从句。例如：He doesnt know if he should bring a prese

13、nt.他不知道是否应该带礼物。4、 What if 用来表示询问或提建议。意思是“如果怎么办？”例如：What if aliens should invade the earth?如果外星人侵略怎么办？What if everyone else brings a present?4 / 13如果其他人都带礼物该怎么办？What if I don t know anyone? 如果我谁都不认识该怎么办？(二) would rather do tha n 的用法 (1 ) would ratherdothan =had rather dothan 是固定用法，意为宁可.(也)不愿，与其. 不如.”

14、通常简写为d rather do。(2)在 would ratherthan这个结构中，必须注意前项和后项的对称，即than 所连的词必须与前面的词项在词性和结构上相一致。例如：I d rather have the red one than the green one. 我宁愿买这个红色的，而不是那个绿色的。He d rather play than work.他宁愿玩耍而不愿学习。You would also rather stay at home and read a book than go to a party. 你也会宁愿呆在家里读书而不愿去参加聚会。功能用语及拓展：本单元涉及的功
