1 C
What a great help it is
what +名词 +it is 表感叹
错误答案原因:
A How后加形容词表感叹 eg.How great sth.is!
B What 后加名词许由a 或 an引领
D great由辅音开头,前应用a 而不是an
2 D
till 直到……(时间)为止
前需加持续性动作

C
D

1C 2D
1.great help 是名词要用what引导,然后可数的help要加a
2。这个翻译比较顺

1.C
强调句what+a/an+n.+it is
how+adj.+it is
2.D
直到 才
didn't+短暂性动词+till
延续性动词+till

C A

关于第一题,告诉你我的密诀。只要记住两个感叹就行:what a pity和how fast!可见,WHAT+a或者an跟的是名词,HOW后面是动词,没有A或者AN。
第二个注意后面的TILL,前面就用带延续性的。

1、B不可数名词help要用what,并且不能用a或an
2、D考till与until的区别,动词要选延续性动词,肯定语态,until要用短暂性动词,要用否定语态

英语中感叹句的构成和用法
感叹句一般是用来表示说话时的喜悦、惊讶等情感。英语感叹句常用"what"和"how"引导,"what"和"how"与所修饰的词置于句首,其它部分用陈述句语序。
一、 由"what"引导的感叹句:"what"意为"多么"用作定语,修饰名词(被强调部分),单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词...

英语中感叹句的构成和用法
感叹句一般是用来表示说话时的喜悦、惊讶等情感。英语感叹句常用"what"和"how"引导,"what"和"how"与所修饰的词置于句首,其它部分用陈述句语序。
一、 由"what"引导的感叹句:"what"意为"多么"用作定语,修饰名词(被强调部分),单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是:
what+(a/an)+adj.+n.+主语+谓语+(it is).
如:
① What a clever girl she is!
多么聪明的姑娘呀!
② What an interesting story it is!
多么有趣的故事呀!
③ What good children they are!
他们是多么好的孩子呀!
④ What beautiful flowers they are!
多么漂亮的花呀!
⑤ What delicious food it is!
多么有味的食物呀!
⑥ What heavy snow it is!
多么大的雪呀!
二、由"how"引导的感叹句:"how"意为"多么",用作状语,修饰形容词或副词(被强调部分)。如果修饰形容词,则句中的谓语动词用系动词;如果how修饰副词,则句中的谓语动词用行为动词,这类句子的结构形式是:
How+adj.(adv.)+主语+谓语+(it is).
如:① How cold it is today!
今天多么冷呀!
② How nice the pictures are!
多么漂亮的图画呀!
③ How happy they look!
他们显得多么高兴呀!
④ How well she sings!
她唱得多好呀!
⑤ How hard they are working now!
他们干得多么起劲呀!
三、在表示同一意义时,英语感叹既可用"what"引导,也可用"how"引导。如:
① What a hot day it is!
How hot the day is !
多么热的天气呀!
② What tall buildings they are!
How tall the buildings are!
多么高的楼房呀!
③ What bad weather it is!
How bad the weather is!
多么糟糕的天气呀!
④ What bright sunshine it is!
How bright the sunshine is!
多么明亮的阳光呀!
四、感叹句在表示激动强烈的感情时,口语中常常采用省略句,其后面的主语和谓语往往略去不讲。
如:① What a fine day!
多么晴朗的天呀!
② What an honest boy!
多么诚实的孩子呀!
③ What red apples!
多么红的苹果呀!
④ How cool!
好凉快呀!
⑤ How wonderful!
精彩极了!
