高中英语语法：It的完整用法精讲 it可用作人称代词、指示代词、先行词及引导词等。 1. 人称代词it，是第三人称单数中性，代表前文已提到过的一件事物。如： 1）That vase is valuable. It's more than 200 years old. 那个花瓶很珍贵，它有200多年的历史。 2）I love swimming. It keeps me fit. 我喜欢游泳，它能使我保持健康。 当说话者不清楚或无必要知道说话对象的性别时，也可用it来表示。如： 3）It's a lovely baby. Is it a boy or a girl? 宝宝真可爱，是男孩还是女孩？ it可用来指代团体。如： 4）The committee has met and it has rejected the proposal. 委员会已开过会，拒绝了这项建议。 it用以代替指示代词this, that.如： 5）--- What's this? --- It's a pen. —这是什么？—是一支钢笔。 6）--- Whose book is that? --- It's Mike's. —那是谁的书？—是迈克的。 2. 指示代词it，常用以指人。如： 7）Go and see who it is. 去看看是谁。 8）--- Who is making such a noise? —是谁发出这样的吵闹声？ --- It must be the children. —一定是孩子们。 3.虚义it无指代性，常用作没有具体意义的主语，出现于表示天气、气候、温度、时间、地点、距离等意义的句子中。如： 9）It is half past three now. 现在是三点半钟。 10）It is six miles to the nearest hospital from here. 这里离最近的医院也有六英里。 11）It was very cold; it snowed and grew dark. 天气很冷；天下着雪，渐渐地变黑了。 it也常用来表示一般的笼统的情况。如： 12）It's awful—I've got so much work I don't know where to start. 糟透了——我有这么多工作要做我不知从何开始。 13）How is it going with you? 你近况如何？ 14）Take it easy. 不要紧张。 it也常用于下列结构： 15）It looks as if the college is very small. 看起来这个学院很小。 16）It seems as though our plan will be perfect. 似乎我们的计划很完善。 17）It's my turn. 该轮到我了。 it也常用于某些习惯用语中作宾语，各该习惯用语有具体意义，但it并无具体意义。如：cab it 乘车catch it 受责，受罚come it 尽自己分内come it strong 做得过分walk it 步行make it 办成take it out of somebody 拿某人出气 4. 先行词it. it充当形式主语或形式宾语，本身无意义，只起一种先行引导的作用，先行词不重读。后面的真正主语或真正宾语通常是不定式结构、-ing分词结构或名词性从句。 （1）用作形式主语

In the centre of the main road into the town, he placed 33 very large stone. Then he 34 (hide ) behind a tree and waited. Soon an old man came along with his cow.“Who put this stone in the centre of the road?” said the old man, but he did not try to remove the stone. Instead, with some difficulty he passed around the stone and continued on his way. 35 man came along and did the same thing; then another came ,and another. All of them complained about the stone but not tried to remove 36 . Late in the afternoon a young man came along. He saw the stone, 37 (say) to himself: “The night 38 (be) very dark. Some neighbors will come along later in the dark and will fall against the stone.” Then he began to move the stone. He pushed and pulled with all his 39 (strong) to move it. How great was his surprise at last! 40 the stone, he found a bag of money. 二· Crying marriage? 31 (surprise), isn’t it?

It is very much 35 same in different places of the province. According to elderly people, every bride had to cry at the wedding. 36 , the bride’s neighbors would look down upon 37 as a poorly cultivated girl and she would become the laughingstock of the village. In fact, there were cases 38 which the bride was beaten by her mother for not crying at the wedding ceremony. In a word, crying at wedding is a 39 by custom to set off the happiness of the wedding through falsely sorrowful words. However, in the 40 (arrange) marriages of the old days of China, there were indeed quite a lot of brides who cried over their unsatisfactory marriage and even their miserable life. 三 In order to know a foreign language thoroughly, four things are neccessary.

B success 名词，保留远动词含义"成功"是不可数名词;如用来代替具体的人(成功者)或具体的事(成功的事情(东西))是可数名词。故排除C,D;A中how是副词，如改成how great a success就是正确的。 3. B 抽象名词不特指时，前不用冠词。 4. D 如将A项中was, since改成is, since是正确的;即从句中谓语先发生。如用B项，是强调句，而强调句前后两个谓语动词在时间上必须一致(a);被强调部分能还回原句中(b)，即因为句中was declared是过去时, B项中is改成was;因为句中was declared是非延续性动词，在years后加上ago将"一段" 时间变成"一点"就是正确的。C项前后时间不一致。 5. C whichever已失去疑问含义，等于 anything that，表示强调; 而 which topic中 which保留疑问含义，译成"哪一个题目"，不符合句义。而A和D中缺少连词。

高一英语语法填空专项练习 （一） 第二节语法填空（共10小题，每小题1.5分，满分15分） Do you ever wonder why you yawn? Why do you open your mouth wide and take a deep breath? Well, a scientist at the University of Maryland is searching for the answer. Professor Robert Provine has been studying yawning for the past two years. But he says he still does not know 31 people yawn. In fact, no one seems to know much about it. Professor Provine’s students have helped him find out more about yawning. They agreed to 32 (watch) while sitting alone in small rooms. In the rooms, they watched television programs, or pictures of people yawning. Or they just sat and 33 (think) about yawning. Students also kept records of when they yawned throughout the day. The professor says he has learned 34 number of things from these experiments. He says yawning seems linked in some way to sleeping. His students yawned most just before sleeping or 35 waking from sleep. He also found that people yawn much when they are __36 (bore ) or not interested in what they are doing. Now, Professor Provine is planning future experiments to help him find the purpose of yawning. He said there is some evidence 37 yawning is linked to 38 (excite). Yawning is common among runners 39 (wait) to begin a race. It is also common among people waiting to make a speech. Professor Provine says he is most interested in learning why seeing someone yawn makes others yawn as well. He says almost anything connected with yawning can make people yawn. As a matter of fact, I found 40 yawning a lot as I prepared this report. I wonder if hearing it can make you yawn. If it does, excuse me, if you did yawn, write and tell me. 答案：31.why 32.be watched 33.thought 34.a 35.after 36. bored 37.that 38.excitement 39.waiting 40.myself （二） 第二节语法填空（共10小题; 每小题1.5分，满分15分） Traditional Chinese culture places much emphasis（重视）on food.

One day as Swift was busy with his writing, 2 boy rushed into his room, knocked some books out of 3 place, threw his parcel on the desk and said, “My mistress(女主人) has sent you two of 4 rabbits.” Swift turned 5 and said, “My boy, that is not the 6 to deliver your parcel.

It’s not only the law, but it’s an agreement we have, and we trust 10 to honor it: we don’t go through red lights. Like most of us, I’m ready to be stopped from doing something bad by the social agreement that disapproves of it than by any law against it. 三 Did you know that in the mountains it can start to snow in August? It snows through the fall and winter. 1 , in spring, when all that snow melts, water falls down the mountainsides. Streams(溪流) form and come 2 to form rivers. Let’s follow one of the rivers in Utah. The Bear River begins nearly 13,000 feet 3 in the mountains. It ends only 90 miles 4 , but it will have dropped about 9,000 feet first! The most surprising thing about this river is where 5 ends.
