They shouldnt argue. 他们不应该争吵。（五）重点语法： 情态动词should的用法 should是情态动词，它的基本用法是必须和其他动词一起构成谓语。情态动词没有人称和数的变化，意为“应该”。 should（应当，应该）用于所有人称，表示劝告或建议。 eg. You should wait a little more. 你应该再多等一会儿。 - I have a very bad cold.我感冒很厉害。 - You should li

5、e down and have a rest.你应该躺下，多喝水。 在这个单元中我们还学到用“could”表示建议，这时could不是can的过去式，而表示比should更加委婉的建议。 - I need some money to pay for the summer camp. - You should/ could borrow some money from your brother.（六）知识点讲解： 1. I dont have enough money. 我没有足够的钱。 enough：adj.充足的、充分的，在句子中可作定语修饰名词，也可作表语。 eg. Do you have

6、 enough time? Six pieces of paper will be enough. 2. I argued with my best friend.我与我最好的朋友吵架了。 argue with sb.意为“与争吵，争论” eg. He often argue with his classmates. 3. My clothes are out of style. 我的衣服过时了。 be out of style / fashion表示“过时”“不合乎时尚” 反义词是“be in fashion”表示“合乎时尚” eg. He is aways in fashion. The

7、sofa is out of style, and I dont like it. 4. Maybe you should call him up. （1）maybe是副词，用来表示推测，译为“也许，或许，大概”。 eg. Maybe you are right. Maybe they will go out for a walk. maybe不同于may be。maybe是一个词，是副词，may be是情态动词may加上动词原形be，意为“或许”，后接形容词、名词、代词等。 eg. It may be true. He may be the man we are looking for. （

8、2）call up sb.打电话给某人 eg. I called up Zhang Hong at eight oclock. 原句中him为代词，所以放在call和up之间，不能说成call up him。 eg. Ill call her up this afternoon. Could you ask him to call me, please.在这个句子中，省略up。 5. I dont want to surprise him. 我不想使他惊讶。 在这句话中surprise是个行为动词，可以说成“surprise sb.”，表示“使惊讶”。 eg. The news surpris

9、es us greatly. surprised adj.惊讶的 surprising adj.令人惊讶的 eg. Im surprised to hear the news. Its a surprising gift, and I love it. 6. No, he doesnt have any money, either. 不，他也没有钱。 either的用法：用作副词，用在否定句或否定词组后加强语气，表示“也”，“而且”。 eg. He doesnt like singing, and he doesnt like dancing, either. either用作代词时，常表示“

10、两者之中任何一个”，常与短语连用或用作宾语。 eg. Either of them will agree with you. I dont like either of the books. 7. I need to get some money to pay for summer camp. 我需要一些钱支付夏令营。 （1）need是个情态动词，也可以是行为动词。 当它是情态动词时，后边直接加行为动词，表示“需要”，但need作情态动词时一般不用于肯定句。它一般用于否定句和疑问句中，例如： You need not meet him.你不必见他。 Need I repeat it?我有必要重

11、复它吗？ 对上一句的简略回答为：Yes, you need. No, you neednt. 此外情态动词must提问时，否定回答时为No, . neednt。 例如：Must he finish the homework now? Yes, he must. No, he neednt. 当need作行为动词时，同其他行为动词一样对待，need后加不定式为“need to do”。 例如：I need to finish the work. 变为疑问句时，不能像它作情态动词时直接提前，而要加助动词do/ does/ did等，例如： He needs to write many words.

12、 改成一般问句：Does he need to write many words? 他需要写许多字吗？ Yes, he does. No, he doesnt. （2）（sb.）pay（money）for sth.为而付款 （sb.）spend（money）on sth在上花多少钱 （sth.）cost sb.（money）什么东西值多少钱 这三个短语都是表示付款。但pay, spend指的是“人”，主语为人，而cost指的是“物”，主语为“物”。 例如说他昨天花10元买了一本书。用以上三个短语分别为： He paid 10 yuan for the book yesterday. He sp

13、ent 10 yuan on the book yesterday. The book cost him 10 yuan yesterday. 注意以上三个动词的动词过去式 paypaid spend spent costcost 以上三个例句的翻译为： 他昨天为这本书付了10元钱。 他昨天花了10元钱（买）这本书。 这本书花了他10元钱。（七）课文解析SB 3aDear Mary, I have a problem, and I need your help. I always thought I was popular at school. But I just found out tha

14、t my friends were planning a birthday party for my best friend, and they didnt invite me. Everyone else in my class was invited except me, and I dont know why. I cant think what I did wrong. Im very upset and dont know what to do. What do you think? Can you help me? Yours, Lonely Kid 1. But I just f

15、ound out that my friends were planning a birthday party for my best friend. 但是我刚刚发现我的朋友们已在为我最好的朋友计划一个生日聚会。 found是find过去式 find out意为“找出”，“发现”，“查出（真相）” find和find out都有发现的意思，二者的语义差别是：find往往指凭一时的直接感觉或偶然发现，而find out则需经一番努力后发现出来，有“查明，弄清”的意思。 eg. He found a bag on the chair. Please find out when the train

16、will leave. “were planning”过去进行时，过去进行时主要表示过去某个时刻或某一阶段正在进行的动作。 eg. What were you doing at nine last night? It was raining hard when I left my office. 过去进行时动词变化（现在分词） eg. When I was cleaning the windows, my brother was sleeping. 2. Everyone else in my class was invited except me, and I dont know why.

17、else修饰不定代词（something, everything, somebody, anybody等），疑问代词（who, which, whom等）和疑问副词（when, where等），要用在这些词后面，译为“别的”。 eg. What else can you do? Is there anything else you dont you. except是介词，表示“除了”，“除了我”译为“except me”。except强调“除去”（后边跟的人或物不包含在里边）。 eg. Except Li Ming, there are forty-five students in the c

18、lass. The class went to the aquarium except me. 3. I dont know what to do. 我不知道做什么？ What to do是疑问句加不定式结构，在句中做宾语，这种结构经常放在tell, show, teach, forget, find out等词后作宾语。 eg. I forgot what to do next. The teacher showed us what to do with it.（八）阅读解析 Life for Cathy Taylors three children is very busy. Their
