The Brownshave a new baby. It's cute. (2)用来表示时间、天气、距离等,如, It'stwelve o'clock now. It's finetoday. (3)用作引导词,代替由不定式,ing形式或从句表示的真正的主语或宾语,如, It's nogood telling him that. It'snecessary for you to do so. (4)用在强调结构中,构成强调句式:It is/was +被强调部分+that/who/whom +句子其余部分,可强调除谓语以外的句子其他成分,如, It wasthis morning that I saw him in the street. It was Iwho saw him in the street this morning. It was inthe street that I saw him this morning. It was himwhom I saw in the street this morning. 2、there be句型 英语表示某时某处或某物时,常用there be句型,这是一种倒装结构,如, There area lot of students playing on the ground. There isgoing to be a test this afternoon. 当主语有两个或两个以上时,动词be常和最近的那个主语取得一致,如, There is apen and three pencils in the pencil-box. Thereisn't a desk, a bench and three chairs in the room. There arelots of people like it, aren't there? there be句型,谓语动词除be之外,还可用其他表示存在,位置移动等意义的不及物动词或词组,如exist, stand, lie, enter, come, happen to be,appear to be等,如, Therestands a house at the foot of the hill. there be句型表示“存在”而have表“有”、“拥有”,所以there be中be不能换成have,但当have表示事物的特征时,可用“主语+have”结构替换there be 句型,如: There arefive doors in the house. The househas five doors. there be 的其它句型: 1、There must be a meeting in the office. 2、There have been great changes since 1979. 3、There being no bus, we had to walk home. I.例题 例1____that he went to sleep. A It wasuntil midnight B That was until midnight C It wasnot until midnight D That was not until midnight 解析:该题答案为C。强调until结构时,要将否定词not移到until前。又如:He didn't leave until twelve 改为It was notuntil twelve that he left. 例2Thereare a lot of students ____ in the class room. A talk Btalking C talked D to talk 解析:该题正确答案为B。There be句型为倒装句,可换为A lot of students aretalking in the class room. 又如:There is a lot of noiseheard out in the street. |
