Both Sam and Tom can play the drums, but Sam plays them better than Tom. 萨姆和汤姆都会打鼓，但是萨姆比汤姆打得要好一些。 both (1) 表示“两者都”， both用在含有be动词的句中，应放在be动词的后面；用在含有行为动词的句中，应放在行为动词的前面， (2) bothand表示“两者都”，both.and在句中连接并列成分，如主语、谓语、表语、宾语等，位置比较灵活。 E.g. Both New York and London have traffic problems. (连接主语) The secretary both speaks and writes Spanish.(连接谓语)【考例】My parents _ doctors. A. both are B. all are C. are all D. are both 拓展：all表示“三者或三者以上全都”的意思，every指三个以上的人或物(含三个)，each指两个以上的人或物(含两个)。 练习：用all,both,every,each填空 1) My brothers and I are _l at school. 2) _ student may have one book. 3) _Tom and Jim are my good friends. 4) Three students are flying kites,they are_ in Class 1. 1. Tara works as hard as Tina. 塔拉学习和蒂娜一样努力。 as.as意为“与一样”，as.as中间接形容词或副词的原级。其否定结构not as/so.as意为“不如”。 E.g. He is as tall as his father. 他和他爸爸一样高。 Tom gets up as early as Jim. 汤姆起得和吉姆一样早。 Lucy isnt as outgoing as Mary. 露西不如玛丽外向。 注意：(1) 其否定式为not as/so +adj./adv. +as。 E.g. This dictionary is not as/so useful as you think. (2) 若有修饰成分，如twice, three times, half, a quarter等，则须置于第一个as之前。 E.g. Your bag is twice as expensive as mine. 你的包比我的贵一倍。 3. You can tell that Lisa really wanted to win, though. 不过，你能看得出来，丽萨确实想赢。 win此处用作不及物动词，意为“赢；获胜”；win还可用作及物动词，意为“赢得；在中获胜”，此时其后的宾语为比赛的项目、奖品或战争等。 E.g. He won the first prize. Who won the race？ 辨析：win与beat win表示“赢得；获胜”，用作及物动词时，其宾语为比赛的项目、奖品或战争等。 E.g. We won the basketball game. beat表示“打赢；战胜”，用于比赛时，其宾语为所战胜的对手。 E.g. Li Lei beat all the runners in the 100-metre race. (2) though此处作副词，意为“不过；可是；然而”，通常用于句末，前面用逗号与句子隔开。 E.g. Jim said that he would come; he didnt, though. 拓展：though作连词，意为“虽然；尽管”，相当于although。 E.g. Though he has no money, he lives very happily. 注意：although/though与but不能同时出现在一个句子中。 E.g. Though he has no money, he lives very happily. =He has no money, but he lives very happily. 2. But the most important thing is to learn something new and have fun. 但是最重要的是学到一些新东西并获得乐趣。 (1) the most important意为“最重要的”，是important的最高级形式。 important的比较级为more important，形容词的最高级形式前必须有定冠词the。 E.g. I think English is the most important of all the subjects. The most important thing is to work hard. (2) have fun意为“获得乐趣；玩得高兴”。 E.g. Its a good place to have fun
