英语语法C
1,This year we will produce______ grain than we did last year.
A,ten percent more B,more ten percent
C,ten percent much more D,much more ten percent
四个选项里面这些百分之几跟比较级连用 ,这是什么用法啊?
2,It is _______ to travel by air than by sea.
A,much exciting B,much more excited
C,a lot more exciting D,a lot more excitted
这是比较级的什么用法没见过
求用排除法一一进行解析

1.选C.只能按照正确的结构去排除其他选项了,如果要用排除法的话.百分比+much+more的结构
2.选 C.A,明显不是比较级错误；V－ing用来修饰物,表示事物的性质或者特点； B.D里面excited都是过去分词,只能用来修饰人,表示人的心理特点,这里指的是交通方式让人兴奋,必须用V-ing.所以BD都错.
另外,比较级前面可以加诸如little,much,a lot等副词来修饰比较的程度,little+比较级表示更...一点,much或者a lot表示更.得多.
