我想问 第一题的4个选项中各有什麼分别?第二题 为什麼选A?第三题为什麼选D 第四题为什麼不是选C (答案是D)
第四题答案是B...打错

Answer 1

第一题：
两岁的英语表达方法,其一是two years old,其二是two-year old.题目的四个选项中只有B和D事对的,而这两者的区别在于two years old 只可以做表语,意思是两岁,如 I am two years old.而two-year-old只可以做定语,意思是两岁的,如 I am a two-year-old boy.但两者不可以互换.因而本题中,合适的答案应该是B.
第二题：
这里相当于一个固定搭配：it is difficult to do sth,the weather在此用指示代词代替就是it.
第三题：
必须弄清楚后面的seemed才是真正的谓语,如果选A B C的话就是把sing当做句子的谓语了,这在语法上是行不通的.singing的成分是后置定语,在此相当于The birds which are singing in the trees...
看一个例句：
The lady standing over there is our English teacher.
（里面的standing over there在此相当于who is standing over there）
第四题：
这道题如果选C的话后面的the road to the harbour is blocked中的is就应该是was了（从句时态的前后一致原则）.
