偶打不出来下划线,所以四个选项都用括号给括起来了.

Answer 1

1,B 改成 knowledge,很明显,a knowledge of ,固定词组,有……的能力,况且,understanding不可数,并且,前面应该是an
2,C 改成 are,主语是 magnificent mountains 和 coastal scenery,两者以上,当然是复数
3,C 改成 tursted,因为整句句子都是一般过去时态,sold,trusted,took
4,B 改成 working,因为by是介词,后面加动名词,构成介宾结构
5,B 改成 on,比较的对象一样,都是rely on sth,只不过后面省略了rely,rely on是固定词组,依赖
6,D 改成 arting,因为devote to doing 是固定词组,on是介词,所以后面跟动名词,构成介宾
7,B 改成 Alberta is believed,去掉当中的it,因为这是被动语态,不需要有it
8,C 改成 maintainings,因为all 后面加名词,并且是复数
9,D 改成 degrees centigrade,因为48大于1,所以用复数
10,D 改成 towards,单词错了
