Lisa often help me with my English.Come on, boys. Help yourselves to some juice. Kate couldn’t help crying when she won the match. 0①need做实义动词,有人称和数的变化,意为“需要”,They don’t need our help. Jim’s bike is broken. He needs to buy a new one. ②need做情态动词时长用于否定句和疑问句中,意为“需要,必要”,后接动词原形,此时need无人称和数的变化,可以直接加not构成否定句,也可直接提到句首变为一般疑问句。You needn’t worry about that. Need we finish the work before Saturday?5.come的用法:做不及物动词时,意为“来,来到”,后接动词不定式做状语,come的反义词是go,后接地点名词时,需加介词to;后接地点副词时,则要省略介词to。He comes to school early every day. Please come here before 10:00. 6.buy的用法:做及物动词,意为“买,购买”,后接名词或代词做宾语。I want to buy some apples.buy后接双宾语,即用于buy sb sth或buy sth for sb结构,My mother buys me new clothes every year. = My mother buys new clothes for me every year.7.sell的用法:sell及物动词,意为“出售;销售;卖”固定搭配:= sell sth to sb 意为“卖某物给某人”They are going to sell me their books.=They are going to sell their books to me.
