There be句型意思是“某處有（存在）某人或某物”,其具體的結(jié)構(gòu)：
（1）There is a / an +可數(shù)名詞的單數(shù) + 地點(diǎn)狀語(yǔ)。
eg：There is a photo on the wall.
（2）There is + (some)+不可數(shù)名詞 + 地點(diǎn)狀語(yǔ)。
eg：There is some water on the table.
（3）There are +可數(shù)名詞的復(fù)數(shù) + 地點(diǎn)狀語(yǔ)。
eg：There are many books on the desk.
（4）There be句型有幾個(gè)并列主語(yǔ),此時(shí)be動(dòng)詞采取“就近原則”,與靠近的名詞的數(shù)一致。
eg：There are two books and a pen on the desk.
There is a pen and two books on the desk.
Grammar
It's running fast.
句子中running是動(dòng)詞run雙寫(xiě)n變成的現(xiàn)在分詞形式,此句子是現(xiàn)在進(jìn)行時(shí)的結(jié)構(gòu),表示“……正在做某事”，由“主語(yǔ)+be+動(dòng)詞的ing形式”構(gòu)成,be動(dòng)詞根據(jù)主語(yǔ)的變化而變化,即I am；He / She / It is ；We / You / They are + 動(dòng)詞的ing形式。
