题目分析:
本题的意思是:乙二醇,作为混有同样体积的水的化合物,通常作为汽车防冻剂使用,在低达华氏30度的时候才有效。
选项分析:
A选项:Correct. 本选项在语法和逻辑上均是正确的。
B选项:在语意上,as…as…和so…as…是相同的。只不过,so…as…通常用于否定句而不是肯定句中
C选项:在比较温度高低时,我们不能说as low temperatures as,只能说temperatures as low as。这是因为,如果将low和temperatures放在一起,那么在语意上就直接变成了“低温”,而不是温度低到什么地步的意思了。
D选项:温度只分高低(high/low),不分多少(few)。
E选项:温度只分高低(high/low),不分大小(little)。
1.固定搭配as...as,B错,so...as一般用在否定句中。
2.句意推理,at后面应该接名词,CDE错
B选项:在语意上,as…as…和so…as…是相同的。只不过,so…as…通常用于否定句而不是肯定句中
C选项:在比较温度高低时,我们不能说as low temperatures as,只能说temperatures as low as。这是因为,如果将low和temperatures放在一起,那么在语意上就直接变成了“低温”,而不是温度低到什么地步的意思了。
"As ___ NOUN as" is only allowed if ___ = "much", "many", "few", or "little".
E.g., Manual High has as many students as Male High.
(not) so much as
so...as 和as...as 意思一致
只不过so...as...一般用于否定句中
原来是 负三十度,,做题的时候以为是dash,,,我就说这道题怎么回事,,,
the most concrete reason is that \"at\" is a preposition. prepositions must be followed by nouns; \"as low...\" is not a noun. (by contrast, note that \"temperatures\" -- which follows \"at\" in the correct answer -- is a noun.)
so...as 和as...as 意思一致
只不过so...as...一般用于否定句中
如 (not否定)so much as
as much as
B选项:在语意上,as…as…和so…as…是相同的。只不过,so…as…通常用于否定句而不是肯定句中
so as 只用于否定句中
错选C-low和temperatures放在一起,那么在语意上就直接变成了“低温”
另外划线的部分前面有个at,需要给这个at加个名词,构成介宾短语,只能是A
在语意上,as…as…和so…as…是相同的。只不过,so…as…通常用于否定句而不是肯定句中
as...a s
介词+名词,不可以接句子
few little 不能修饰问题 排除de
so as 只用于否定句中 排除b
at后面缺少名词排除c
