判断以下英语句子的正误，原因?

1.对。 would you please do sth,
feed my fish 喂鱼
while I am out 当我外出的时候

2.第二句应该是陈述句。
句子是对的。
The radio says （that）it will be snow tomorrow.

3.还是对的。
planted是过去分词作后置定语。
实际上是they are the trees (which were) planted last year.

(1)正确.
(2)错误.应改为:The radio says it will be snowy tomorrow.
(3)错误.应改为:These are the trees planted last year.
