abit和alittle区别.docx

a bit和a little都作"一点儿"讲,但用法不同 1)a bit和a little在肯定句中修饰动词、形容词、副词和比较级时可以互换,表示"一点儿"的意思例如: The speaker spoke up a bit/a little so as to make himself heard more clearly. 演讲者把嗓门提高了一点儿,以便使别人听得更清楚 2)a bit和a little在否定句中的意思恰恰相反,not a bit相当于"not at all"(一点儿都不);not a little相当于"very(much)"或"extremely"(很、非常)例如: She is not a bit tired.(=She is not tired at all.)她一点都不累 3)a little可以直接作定语修饰名词,而a bit则要在后面加of构成短语才能作定语,两者都只能修饰不可数名词例如: There is a little/a bit of food left for lunch. 午饭只能吃剩下的一点食品了 4)a bit of的另一种形式是bits of,a little则没有这种变体。

例如:Besides this,he used part of an old army wireless set,and some bits of wood.除此之外,他还利用了一部分旧的军用无线电发报机的一部分零件和一些木片 so as to 和in order to的汉语意思应该是一样的“为的是，为了”它们的英语功能也是一样的，都可以用来引导目的状语它们的不同之处就在于so as to 不能用于句子的开头，在句子开头只能用in order to. 另外， 1.in order to 一般用in order that加从句来替换；而so as to 一般用so that加从句来替换in order that 可以在句首，so that和so as to 一样不能在句首 2.当这两个短语后的不定式动词的逻辑主语和句子的主语一致时，“in order to , so as to +不定式”可以简化为“不定式” In order to get to school on time,he got up earlier.这个句子可以表达为下列几种方式：In order that he could get to school on time,.... He got up earlier in order to get to school on time. He got up earlier in order that he could get to school on time. He got up earlier so as to get to school on time. He got up earlier so that he could get to school on time. To get to school on time, he got up earlier. （这种不定式有时可以表示目的以外的状语）1、 not only…but also…的用法 用于连接两个表示并列关系的成分，着重强调后者，其意为“不仅……而且……”;其中的also有时可以省略。
