问题解答:

我来补答
B
首先不允许,是因为能力不够.所以C和D用much显然不合适
enough + 形容词 ,enough要放在形容词之后.所以,A不对
16岁不允许开车因为在那个年龄人们还不够严肃认真(16岁不知道后果.不知道负责人)
再问: 帮我补个enough 的所有用法,谢谢~
再答: 1. 用作名词,表示“足够(的数目或数量),没有复数形式,但根据情况可表示复数意义。如: Enough has been said about this subject. 关于这个问题已说得够多了。 Enough were present to constitute a quorum. 出席的人数够法定人数。 2. 用作形容词,通常修饰复数名词或不可数名词,可放在被修饰名词之前或之后(但以前置为多见)。如: He has enough money to buy a car. 他有足够的钱买辆汽车。 We have time enough to get to the airport. 我们来得及赶到机场。 【注】有时与某些具有形容词意味的名词连用,此时 enough 必须后置,且该名词通常不用冠词。如: I was fool [=foolish] enough to accept his offer. 我接受他的提议真是太傻了。 3. 用作副词,可用来修饰形容词、副词、动词等,此时总是放在被修饰语之后。如: He didn’t practise enough. 他练习得不够(from www.et777.cn)。 She isn’t good enough for [=to pass] the exam. 她的功课还不够好,还考不及格。 I don’t know him well enough to ask him for help. 我和他不够熟,不能请他帮忙。 其后可接不定式或介词 for, 但一般不接that-从句。如: 在这条河里游泳水够深吗? 正:Is the river deep enough to swim in? 正:Is the river deep enough for swimming in? 误:Is the river deep enough that people can swim in? 在口语中,出于客气和礼貌,人们常用类似于下面这样的句型: Would you be kind enough to open the window? (=Would you be so kind as to open the window?) 请你打开窗户好吗? 4. 在通常情况下,enough 不能用作表语,除非其主语是代词或是那些具有(或暗示有)数量意义的名词。如: That’s enough. 够了(from www.et777.cn)。 One such dictionary is enough. 这样的词典一本就够了。 Six bottles of wine will be enough. 六瓶葡萄酒就够了。 比较下面的正误句子: 误:The beer isn’t enough. 啤酒不够。 正:There isn’t enough beer. 啤酒不够。 误:Was the time enough? 时间够吗? 正:Did you have enough time? 你们时间够吗?
