辨析 receive accept
1).表示“受到教育/处罚/支持”和“接待客人”时只能用receive;
表示“接受某条件”时只能用accept。
2）.从含义上说，receive只表示“被动地收到”这一事实，但并不一定接受；
accept则表示主观上收到并且接受的意味。 ExamplesI've received his letter.
Tina accepted Tom's flowers,because they are beautiful.
Jim has received an invitation but he doesn't think he'll accept.GrammarsShe asked people if they could help her grandma see the world through pictures.
该句中有一个由if 引导的宾语从句。if 在此意为“是否”，可以与whether互换使用。
eg:I wonder if/whether he will come.
Attention注意：1）宾语从句为否定句时，只用if.
2)以下场合只用whether.
a 从句中含有or not时
b 从句跟在介词后作宾语时。eg:It depends on whether it will be fine.
c 为了强调宾语部分而把从句放在句首时。eg:Whether he will come i am not sure.
d 句中已经含有if 引导的条件句，为避免产生歧义时。eg:He asked me whether i'd move to Xi an if i got the job .
e 用在动词不定式之前时。eg:i don't know whether to go there at once.PractiseFill in the blanks with the correct forms of the words in the box.
