1.There be 結(jié)構(gòu)
    a.這是英語(yǔ)中常見(jiàn)的一種結(jié)構(gòu)，表示“某地有某物”其含義為“存在有”。
    eg.There are twenty girls in our class.have也解釋為“有”但是與there be有區(qū)別，它的含義是“所有，屬有”，其主語(yǔ)為某人。eg.I have a nice watch.
    b.There be 結(jié)構(gòu)中的be動(dòng)詞要和后面所跟名詞保持一致。

    劃⑴How many rivers are there near our school?
    ⑵What’s near our school?
    d.there be 結(jié)構(gòu)的一般將來(lái)時(shí)，同學(xué)們較難掌握，其正確形式為：there is going to be

    a.So+be(助動(dòng)詞，情態(tài)動(dòng)詞)+主語(yǔ)。表示某人也是如此。
    eg.Mike has bought some foreign stamps.
