三、语法：
由连词whether或if引导的宾语从句。
核心知识
1．语法：由whether或if引导的宾语从句。
二者均表“是否”，均可用来引导宾语从句，宾语从句要用陈述语序。
e．g： Tom asked me whether/if I liked the twins.
注意：1)if可以引导宾语从句，也可以引导条件状语从句，而whether不可。
e．g： I’ ll go to the park if it doesn’ t rain tomorrow.
2)whether可置于句首，而if则不能。
e．g：Whether he will be back tomorrow remains a question.
3)从句中带有or not时，用whether，不用if.
e．g：I don’ t know whether he will come or not.
4)在动词不定式前只能用whether. 不用if.
Please tell me whether to go or to stay.
2．so it is：表“是的，的确这样”。
so可用来代替上文中的形容词，名词或动词，表赞同。句型为So+主语+助动词、情态动词。
e. g：“It was cold yesterday. ”“So it was
昨天很冷。的确很冷。
注意区分so+助动词+主语表“…也是”。
e. g．：He is a doctor．So is my sister.
3．lonely与alone.
Lonely意为“孤独的”。强调主观感受作形容词，可作表语和定语。
e. g．I feel lonely. 我感到孤独。
He’ s a lonely traveller. 他是个孤独的旅行者。
alone：意为“单独的”强调客观上独自、可作形容词或副词。
e. g．He likes living alone．He doesn’ t feel lonely.
4．get on with：”与…相处”
get on well with sb. 意为“与…相处融洽”。
get on well with．sth. “…进展(顺利)”。
e．g：I’ m getting on well with my classmates.
我和我的同学们相处得很融洽。
How are you getting on with your work?
你的工作进展如何?
5．try on：“试穿”
形式有try on sth和try sth on，当sth是由代词代替时，只能放在try与on中间?
Please try it on. 请试穿一下吧!
6．I can’ t decide which sweater to buy.
我不能决定要买哪件毛衣。
“Which sweater to buy”是decide的宾语。在show．know, tell teach．find out．learn forget．decide等动词后面，常用“疑问代词或副词+不定式”作宾语。
e. g：I don’ t know how to get to the post office.
我不知怎样去邮局。
Can your tell me when to start.
你能告诉我何时出发吗?
