高二下学期英语期末知识点梳理

1)whether和if常用来引导宾语从句,这时两者的含义区别很小,一般可通用。例如:①I don't know whether/if they will come to help us. 我不知道他们是否来协助我们。②I am not sure

whether/if I'll have time to go with you. 我很难说我们是否有

时间跟你们一起去。上面两句无区别。

但是,当whether与or not连成一个词组时,whether不可换用if。例如:③I don't know whether or not they will come for our help. 我不知道他们是否要来求我们支援。【注意】若whether和or not不连在一起,在口语中能够用if取代whether,当然也能够用whether。例如:④I am not certain if/whether the train will arrive on time. 我没有把握火车是否准时到达。⑤I don't care

if/whether your car breaks down or not. 我不在乎您的车是否是

会出故障。

此外,还有三种情况值得注意:

(1)在介词后面只能用whether,不能用if。例如:①This depends upon whether we are determined to do it. 这件事要看我们是否有

决心去做。②It depends on whether he is ready. 这件事要看他

是否有准备。③I am not intereste d in whether you'll come or not. 你来不来我不感兴趣。④We haven't settled the question

of whether we'll renew our supplies of coal for factory. 是否

要为我们工厂补充一些煤,这个问题我们还没有决定。 (2)在动词不

定式之前,只能用whether,不能用if。例如:①He doesn't know whether to stay or not. 他不能知道是否要留下来。②She

doesn't knows whether to get married now or wait. 是否现在结

婚或是等待她不知道。 (3)在及物运动discuss后的宾语从句中,只

能用whether,不能用if。例如:①We discussed whether we should make a change in our plan. 我们讨论了是不是要对我们的

计划作一些修改。②We were discussing whether we should

discuss the business with them. 我们正在讨论我们是否要和他们

谈这个生意。

2)引导主语从句时,只能用whether,不能用if。例如:①It is unknown whether he will come. 他是否来还不知道。②Whether

the news is true remains a question. 这个消息是否真实仍然是个

问题。

3)引导表语从句时,只能用whether,不能用if。例如:①What we want to know is whether he will come to speak to us tomorrow. 我们想知道的是他明天是否来给我们讲话。②The question is whether they can take our advice. 问题是他们是否能接受我们的

意见。4)引导同位语从句时,常用whether。例如:①The question whether we'll build another lecture buil你到底想说什么 hasn't been settled. 是否要另建一幢教学楼的问题还未决定。②The question whether he'll come is unknown. 他是否来的问题还不知道。

5)能够用来引导一个否定的宾语从句,whether则不能用来引导否定

的宾语从句,因为它表示正反两方面的选择意义比较强。例如:

①Tell me if it is not going to rain, please. 请告诉我明天是

否不会下雨。②He considered if he shouldn't tell her the secret. 他考虑他是否不该告诉她这个秘密。

6)if除引导宾语从句外,还能够引导条件状语从句,作“是否”解。在容易引起混淆产生歧义的情况下,就不可用if,而须用whether。

例如:①Please let me know if you intend to come.这个句子有

两种解释: A:“请让我们知道你是否想来。” B:“如果你打算来,请让我们知道。” 第一种解释是把if引导的从句看作宾语从句,把

动词know视为及物动词(vt.);第二种解释是把if引导的从句当作条

件状语从句,把动词know看作不及物动词(vi.)。在口语中,我们能

够通过语调来表示两者的区别;但是,在书面语中,无上下文(如一张

便条上写着这句话),那就含混不清了。如果我们想表达的第一种含义,就得用whether来改写第一句。①Please let me know whether you intend to come. 又如:②Let me know whether he has left for Shanghai. 告诉我他是否已经去上海了。③Let me know if he has left for Shanghai. 如果他去上海,请告诉我一声。此外,whether

还能够引导让步状语从句,作“无论、不管”解。

His art and talent were recognized by almost no one. He suffered from a mental illness that led him to cut off part of his left ear in 1888 and to shoot himself two years later. But after his death, he achieved world fame. Today, Dutch artist Vincent van Gogh is recognized as one of the leading artists of all time. Now, 150 years after his birth on March 30, 1853, Zundert, the town of his birth, has made 2003 “The van Gogh Year” in his honor. And the van Gogh Museum in Amsterdam, home to the biggest collection of his masterpieces, is marking the anniversary with exhibitions throughout the year. The museum draws around 1.3 million visitors every year. Some people enjoy the art and then learn about his life. Others are first interested in his life, which then helps them understand his art. Van Gogh was the son of a pastor(牧师). He left school when he was just 15. By the age of 27, he had already tried many jobs including an art gallery salesman and a French teacher. Finally in 1880, he decided to begin his studies in art. Van Gogh is famed for his ability to put his own emotions into his paintings and show his feelings about a scene. His style is marked by short, broad brush strokes(笔画).“Instead of trying to reproduce exactly what I have before my eyes, I use color more freely, in order to express myself more forcibly,” he w rote in a letter to his brother in 1888. Van Gogh sold only one painting during his short life. He relied heavily on the support from his brother, an art dealer who lived in Paris. But now his works are sold for millions of dollars. His portrait of Dr. Gacher sold for $89.5 million in 1990. It is the highest price ever paid for a painting. “I think his paintings are powerful and the brilliant colors in them are attractive to people,” said a Van Gogh’s fan. 1. All through his life, Van Gogh . A. depended on his brother B. worked hard on art studies C. was not recognized by people D. expressed himself in paintings 2.Van Gogh killed himself because of .

Earthquake safety is very important and there is more to it than just keeping buildings from falling down. So if your home is in an earthquake area, you should prepare carefully before the earthquake comes. First, make sure you buy a house which is earthquake safe. All pipes should be fixed to the wall and all walls should be especially thick and strong. You also have to make sure that there are bolts underneath your house. They are one of the most important ways of protecting a house. Make sure the building has no broken windows and is well repaired. Second, look at the objects in your house. Those in the living room, which are the most likely to hurt us, are computers, televisions and lamps. They can be tied to tables or stuck to them so they won’t easily move around. The kitchen, which is also very dangerous, must have strong doors on all the cupboards. This is the place where

Alternative Press. D. Sound & Vision. B I dropped out of college after my freshman year. Three years later, I quit a dead-end job and returned college. I saw school as my way out. But I quickly found myself facing the same roadblocks that had caused me to quit before: I was confused with college-level algebra and a heavy workload of reading and writing assignment. Moreover, I was unsure of my career direction. I was ready to drop out again. Then a smartly-dressed woman walked confidently to the front of my English composition class. “Look at you! Look at each and every one of you,” she said. “You’re here to change your lives for the better. And you’re going to make it!” I can’t remember the rest of the speech, but it changed the course of my college career and my life. Mrs. Smith didn’t know me from any of the other 40 faces in her classroom, but I felt she speaking directly to me. Having trouble keeping up with the workload? Break it down into small pieces, and set up a schedule that suits you. If college algebra is too difficult, drop back to introductory college math. As for English composit ion, she gave us writing assignments we could relate to. “Go for the best, kid. You’re worth it,” she’d say. I graduated from that college and went on to get my bachelor’s degrees. Today, as a college instructor, each fall when I stand in front of a new class, I think of Mrs. Smith and how much teachers can affect their students. She couldn’t have known it when she gave that pep talk, but she made a huge difference in my life. 4. Why did the author want to quit school again? A. He wanted to return to hid former job. B. He decided on his future career. C. The academic pressure seemed unbearable. D. Many changes took place in his life. 5. How did Mrs. Smith help the author? A. She made him feel relaxed. B. She helped him with algebra. C. She talked to him directly. D. She brought him courage and faith. 6. What can we infer about the author?
