以下句子是否正确，如果错，错在哪里。谢谢

1.I telephoned to the school this morning.
改: I telephoned the school this morning.

2.He shave at seven o'clock last morning.

既然是“昨天早上”那么是过去式了 用"he shave" 不当```况且即便是现在试 也得是"he shaves" 还有我们一般不说"last morning" 用 "yesterday morning

改: He shaved at seven o'clock yesterday morning.

3.She boiled some potatoes for lunch at noon.
这句话grammar上没什么问题````逻辑上么````你已经说了土豆是做lunch的``就不用说"at noon"了``因为"lunch"已经表明了时间 而且你煮土豆嘛````这样说不怎么好```因为外国人不煮土豆``：
改：She cooked some potatoes for lunch.

1.I telephoned to the school this morning.[没错]
2.He shave at seven o'clock last morning.[shave --- shaved]
3.She boiled some potatoes for lunch at noon.[boiled -- cooked]

第二句明显shave时态不对。。第一三句粗看不错。。就是不太舒服。。大概是用法问题

1.telephoned the school
2.shave--shaved
3.boiled--boils

K~
1 I called the school this morning. 我早上打过电话给学校了
2 He shaved at seven
