英语:1.How is it _____he has made such rapid progress?

4个回答

  • 1、这个应该还原一下,我觉得第一个词应该是what,还原之后为:it is what that has made him such rapid progress.这应该是个定语从句.

    2、这道题也用还原法,还原之后为:The guide(they climbed the mountain with whose aid )was a very patient man.括号内是定语从句,修饰guide的,主句是括号外面的.定从中是说她们在导游的帮助下爬山.在某人的帮助下是with one's aid.

    3、offer sth to sb .offer sb sth.offer有主动提供的意思.support sb.with sth.

    4、记住prove证明,没有被动语态,和happen当发生讲一样,它们都是及物动词

    及物动词无被动语态.

    5、我没有分散任何精力或注意力

    1、A:C=2*0.2*2=0.8 D:C=1*0.3*5=1.5 可是KClO3的clo3会点解成氯酸跟离子,到最后还是远远小于0.8的

    2、SO3在标准状况下是固态.
