新概念2,23课,问问
1.(It) is a pity that he could not come .
2.(There )is a bus that leaves in ten minutes.
3.(There )were some men digging up the roap outside my house.
4.Look at those clouds.I think (there) will be a thunderstorm.
5.(It )is unusual for hum to be late.
6.(It) has been very cold this year.
7.(There) has been no news of him .
8.I am sure( it) will be fine tomorrow.
9.After dinner (there) will be a long discussion on politics
10..When will (it) be convenient for you to come?
it和there用法,以及区别,会加钱!
1.It is a pity that he could not come.
这里it是强调句一部分.
强调句的结构:it is +强调成分+that +其它成分;
强调句特点一:去掉it is ...that 表达意思仍然完整;
强调句特点二:强调谁,就把谁放到it is和that 之间,其它成分放在后面;
该句子强调的是宾语,如果还原成普通句,He could not come a pity.
第2.3.7.9 句 都是 there be 句型.
1.there be句型的含义:表示某个地方有某人或某物,俗称“有木有”句型;
2.there be 句型的特点:本质是个倒装句,句子的主语在后面;
如,there is a bus...其实正装语序是 a bus is there...;
3.there be 句型中的be的意义:be动词有人称和时态的变化;
如,2.there is a bus 表示现在那有一辆巴士,十分钟后会开走.
一辆巴士,描述现在的一般情况,be动词变成is;
再如,9.after dinner there will be a long discussion...
晚饭以后,将会有一场关于政策的长时间的讨论.描述将来的情况,be动词变成will be;
3.it 在英语中用法十分广泛,除了上述的强调句外,还可以表示时间,天气以及一些抽象概念;
如,It has been very cold this year,今年一直都很冷.(表示天气);
再如,When will it be convenient for you to come?你什么时来方便呢?(表示时间)
4.It is unusual for him to be late.这里it 是形式主语,指代真正的主语 to be late ;
it 作形式主语的使用时机:主语过长,防止句子头重脚轻,英文句子的“尾重”原则;
还原成非形式主语句,To be late is unusual for him.意思都为,他很少迟到;
