Paris is one of the biggest cities in the world. 5.选择疑问句，A，B or C？,一、忌不同类事物进行比较。 他的电脑比我的便宜。 误：His computer is cheaper than I. 正：His computer is cheaper than mine. 析：在比较级的句子中，相比较的双方必须是同类事物，否则会造成歧义。这里mine=my computer。,比较级使用禁忌,误：The population of China is larger than India. 正： The population of China is larger than that(=the population) of India.中国的人口比印度的人口多。 误：The students of Class Two study harder than Class One. 正：The students of Class Two study harder than those of Class One. 二班的学生比一班的学生读书用功。 误：In winter it is colder in Beijing than Shanghai. 正：In winter, it is colder in Beijing than in Shanghai. 冬天北京比上海冷。,二、忌自己与自己进行比较。 1. 比尔比他班上的其他男孩都高。 误：Bill is taller than any boy in his class. 正：Bill is taller than any other boy in his class. 正：Bill is taller than the other boys in his class. 析：在比较级的句子中，同一类人或物在同一范围内进行比较，要把自己排除在比较范围之外。,2. 玛丽歌唱得比班里的任何一个男孩都好。 误：Mary sings better than any other boy in her class. 正：Mary sings better than any boy in her class. 析：在比较级的句子中，主语和范围之外的人或事进行比较时用“any + 单数名词“。又如： Shanghai is larger than any city in Japan. （上海比日本的任何一个城市都要大。） 但是： Shanghai is larger than any other city in China. （上海比中国任何一个其他城市都大。）,三、忌错用修饰词。 吉姆比他妹妹大得多。 误：Jim is very older than his sister. 正：Jim is much older than his sister. 析：比较级前面常用much, a little, far, even（更），a lot, still（更）等副词来修饰，表示程度，不可用very, too, quite等词来修饰。,四、忌错用表示范围的介词。 李玲在我们班年龄最小。 误：Li Ling is the youngest of our class. 正：Li Ling is the youngest in our class. 析：表示范围的短语有 1）in + ones/the + n. 在里 2）of + the + 数词 + 名词复数 在几个中 3）of + all + the +名词复数 在所有的中 如：Tom writes best of the three boys. 在这三个男孩中，汤姆写字最好。,五、忌错用主格宾格。 下面两句话中，than后面一句用I， 一句用me,两者都可以。 He is taller than I. 他比我长得高。 He is taller than me. (多用于口语中) 但是有些句子中，用主格和宾格时意义不同。例如： I like the boy better than her.我喜欢那个男孩胜于喜欢她。 I like the boy better than she.我比她更喜欢那个男孩。 Mr Smith likes his friend better than his wife. 史密斯先生比他的妻子更喜欢他的朋友。(也可理解为：史密斯先生喜欢他的朋友胜过喜欢自己的妻子) 如果把省略的部分写出来，便可避免歧义： Mr Smith likes his friend better than he likes his wife. 史密斯先生喜欢他的朋友胜过喜欢自己的妻子。,六、几种句型的转换 同一个意思往往可以用不同的句型来表达。例如： Jack is taller than Jill. 杰克比吉尔长得高。 =Jill is shorter than Jack.吉尔长得比杰克矮。 Jill is less tall than Jack. =Jill is not as tall as Jack. 吉尔长得不如杰克高。 This book is less interesting than that one. =This book is not as interesting as that one. 这本书不如那本有趣。 Bill is the tallest boy in his class. =Bill is taller than any other boy in his class. =Bill is taller than the other boys in his class. =Nobody is taller than Bill in his class.,一、词汇,1、The flowers are very _.
