Unit 3语法篇_理解并掌握常见连词及表示原因连词的用法1. 常见连词(and, but, or, so)的用法 (1) and“和，而且，又”，表示并列关系。例如： I woke up and got out of bed. 我醒了就起床了。 (2) but“但是”表示转折关系。例如： I got up early but I still missed the first bus. 我起得很早，但仍然错过了早班车。 (3) or“或者；否则”。例如： Hurry up, or you will be late. 快点儿，否则你就要迟到了。 (4) so“所以”，表示因果关系。例如： I heard some noise outside, so I went out of the room to see why.我听见外面有些声音，所以走出房间去看看是怎么回事。2. because, since, as, for表示原因的区别 because, since, as 都是表示“原因”的从属连词，引导原因状语从句；而“for”也表示原因，引导的是并列句。语气由强至弱一次为：because, since, as, for。 (1) because表示直接原因，它所指的原因一般是听话人所不知道的，语气最强。常用来回答why的提问，一般放在主句之后，也可以单独存在。例如： -Why are you late? 你为什么迟到了？- Because I missed the early bus. 因为我错过了早班车。 (2) since侧重主句，从句表示显然的或者已为人所知的理由，常译为“因为，既然”，语气比because稍弱，通常置于句首，表示含有一种勉强语气的原因。例如： Since everybody is here, lets begin. 既然大家都在这里，我们开始吧。 (3) as是常用词，它表示的原因是双方已知的事实或显而易见的原因，或者理由不是很重要；比since语气弱，没有since正式，常译为“由于，鉴于”。从句说明原因，主句说明结果，主从句并重。例如： As I was not ready, they went without me. 由于我没有准备好，他们没有带我去。 (4) for表明附加或推断的理由，其后的分句不能放句首，语气最弱。例如： It mush have rained last night, for the ground is wet. 昨晚一定下了雨，因为地面是湿的。3. 其他常见连词 (1)if 如果，表示条件，引导条件状语从句。 unless, 除非，如果不=ifnot。例如： If it doesnt rain tomorrow, we will go to the park.(前半句可改为Unless it rains tomorrow) 如果明天不下雨，我们就会去公园。 (2)although虽然，尽管，引导让步状语从句。不与but连用。例如： Although no man agreed with him, he held on his views. 尽管没人赞同他的观点，他还是坚持自己的看法。1.

These stories often have a lesson to teach, too. Here are the stories of some everyday household inventions.Canned Food and the Can OpenerGet It Right!Peter Durand invented canned food in 1810, but there was a problem. Durand didn't have a good way to open the cans. In 1858, Ezra Warner invented a can opener. It used a piece of metal to cut and remove the top from the can, but it was difficult to use. Finally, in 1870, William Lyman added a wheel to the can opener. The metal went around the top of the can and removed it easily. Finally, people were able to open cans without a lot of work. Canned food was soon popular.Frozen FoodA Little Good Luck Can Help!Clarence Birdseye had the chance to go on a trip to如e Arctic. When people there caught fish, they put the fish in a container (容器) of ice to freeze it quickly. When people cooked the fish later, it was still good! This gave Birdseye an idea. He thought people could also have this kind of food at home. In 1926, Birdseye invented frozen food. People were able to store food in freezers for a long time.Air ConditioningOne Answer to Two Problems!Printing companies make books, so they use a lot of paper. Sometimes, changes in the weather can hurt the paper. In 1902, Willis Carrier invented air conditioning to control the temperature inside his printing company. This saved the paper. People soon realized other benefits of air conditioning. They started to air condition their homes in the summer. Carrier's invention changed the world!1. When was canned food invented? A. In 1810.          B. In 1870. C. In 1902.          D. In 1926.2. After the trip to the Arctic, Clarence Birdseye invented _. A. canned food             B. can openers C. frozen food           D. air conditioning3. Changes in weather _ in Willis Carrier's company. A. helped to keep food           B. hurt printing paper C. caused health problems        D. made rooms comfortable4. According to the passage, which of the following may lead to inventions? A. People's needs.             B. Public support. C. Modern technology.          D. Practical suggestions.BLooking for an original way to raise money for charity? Has your school run out of clever and fun ideas? Dont give up. There are several ways to support your favorite charity and enjoy yourselves at the same time.How about holding a bean bath competition? “How does this help?” you may ask yourselves. Well, its very simple really- you agree to sit in a bath full of baked beans, then for every minute you stay in it, people pay money! The longer you stay in the bath, the more money you collect for the charity your school has chosen! Its extremely messy, but its good fun! Just a piece of advice, though. Let your parents know what youre doing. Wear old clothes because theyre going to need washing after the competition!Heres another idea that we used at my school: organize a car wash. Everybody who has a car sooner or later washes it or has it washed. So why dont you and your classmates do the job? The money the car owners pay for having their cars washed will go towards your charity. When we did it, we had an amazing time! At first, some of us were worried about getting wet or dirty and its true. But we also had fun, and at the end of the day it was really worth it! On the other hand, if you dont feel like getting wet or messy, but have some musical talent, how about organizing a street concert? Street musicians can make a lot of money and so can you if youve got the talent and courage it takes to play in front of an audience. You just need to find a suitable place (make sure youre allowed to play music in that public place), practise for a few hours with your friends first, and give it a try!I hope all these ideas have helped you a bit, and if youve got any other great suggestions, we would love to hear them. We can publish them, so other people can use them, too. Good luck!5. Holding a bean bath competition, you would_. A. ask yourselves many questions B. sit in a bath full of baked beans C. put on old clothes after the bath D. ask your parents to wash the clothes6. What did the writer think of the car wash? A. He thought they could have fun. B. He was upset about getting wet. C. He thought many students were too worried. D. He thought it was an easy way to collect money.7.
