擔(dān)當(dāng)be supposed to 與不定式的一般形式搭配時(shí)往往表示不同的意義.例如:
Why are you driving so fast in this area? You are supposed to know the speed to know the speed limit. (你應(yīng)該曉得速度限制)

句子成分(members of the sentence)
英語(yǔ)的句子由主語(yǔ)部分與謂語(yǔ)部分組成。具體地講，主要有下列六種句子成分：
1)主語(yǔ)(subject)它是句子所要說(shuō)明的人或事物，是一句的主體。如I study English(我學(xué)習(xí)英語(yǔ))中的I。
2)謂語(yǔ)動(dòng)詞(predicate verb)它是說(shuō)明主語(yǔ)的動(dòng)作或狀態(tài)的，如I study English中的study。
3)表語(yǔ)(predicative)它是放在連系動(dòng)詞之后表示主語(yǔ)的身分或特征的，如I am a student(我是一個(gè)學(xué)生)中的student;Our classroom is clean(我們的教室很干凈)中的clean。
4)賓語(yǔ)(object)它是表示及物動(dòng)詞動(dòng)作的對(duì)象的，如I study English中的English。介詞后面的名詞或代詞，叫做介詞的賓語(yǔ)，如They don't work on Sunday(他們星期天不工作)中的Sunday，就是介詞on的賓語(yǔ)。
5)定語(yǔ)(attribute)它是限定或修飾名詞或代詞用的，如He likes to drink co1d milk(他喜歡喝冷牛奶)中的co1d。
6)狀語(yǔ)(adverbial)它是修飾動(dòng)詞、形容詞、副詞用的，如He works hard(他努力工作)中的hard。
