希望老师能说出原因
解题思路: 见过程
解题过程:
1.填out, come out 是固定词组,意思是出版,发行。
2.选B. 考点是enough 的用法,enough 这里是名词,意思是我吃饱了。
enough一词在英语中既可放在被修饰的词之前,又可放在被修饰的词之后。因此很多同学觉得enough 很难理解。其实这涉及到enough的词性问题。请看下面几个例句:
1. He is not old enough to go to school. 他年龄太小,不能去上学。
2. But there were not enough people to pick them. 但是没有足够的人采摘它们。
3. Six bottles of wine will be enough. 六瓶葡萄酒就够了。
要想搞清楚上面3个句子中enough的词性及含义,得先掌握它的用法规律。
enough作副词用时,意为“充分地;足够地”,通常要把它放在所修饰的形容词、副词或动词的后面,常与不定式或介词for连用。如:
1. You don't practise enough at the piano. 你钢琴弹奏练习得不够。
2. Is the river deep enough for swimming? 河水够深来游泳吗?
enough作形容词,意为“充足的;足够的”,在句中可作定语或表语。作定语时,一般放在它所修饰的名词前面。如:
1. I have enough money to buy a colour TV set. 我有足够的钱买台彩电。
2. Fifteen minutes is enough time for you to have a coffee. 15分钟够你喝杯咖啡了。
enough也可作名词用,意为“充分;足够”。如:
I have had enough, thank you. 谢谢你,我吃饱了。
看了以上有关enough的用法,不难发现:在例句1中,enough是副词,作状语,用来修饰形容词old;而在句2中,enough是形容词,作定语,修饰名词people;句3中enough 是名词。
最终答案:略
