解答 答案选C
can 可以,能,可能;must 一定,必须;may 可以,可能;would愿意;将要;会.根据要 achieve my goal(实现目标),所以选must必须.故选C.
点评 有时must的否定形式也是考查的重点.
1.must的否定形式mustn't,表示禁止,意思是"不能,不许";
例如:You mustn't waste time any longer.你不能再浪费时间了.
2.由must引导的疑问句,肯定回答用must或have to,否定回答用needn't或don't have to意思是"不必".
例如:A:Must I go back home before 10 o'clock?我必须在10点以前回家吗?
B:Yes,you must/have to.是的,必须.No,you needn'/don't have to.不,你不必.
