英语题,急判断下列句子是否正确,不正确的请改正.1.The door keeps opened.____________

以下是我的解析：
1.The door keeps open.【open 即可表状态 不能用opened】
2.Jack is trying to help me.【没有try to doing 此处根据意思是 try to do 努力做某事】
3.I have found my watch since a week ago./ I found my watch a week ago /
I have found my watch for a week .【since 用于完成时 有三种改法 建议选择改动最小的】
4..His parents heard the bad news on the radio.【telephone radio 等都用介词 on】
5.Did you buy a car last month?【did does do 等等在疑问句中 后面跟动词原形】
6.It’s worth reading the book.【be worth doing 固定词组】
7.The house has cost ￡100,000.【cost是不规则动词,过去式和过去分词跟原形一样】
8.The sun rises in the morning.【没有具体时间 所以表示这类自然真理等用一般现在时】
9.The moon rose at 7o’clock last night.【因为这句有了时间7：00 还有昨晚 所以一般过时】
10.Tom hasn′t decided yet ./ Tom cannot decide【否定句不用already 用 yet 也可去掉】
如果您满意我的答案

1.The door keeps open (open 本身就是形容词：打开的 keep+形容词：保持一种状态）
2.Jack is trying to help me. （try to do sth：试着做某事）
3.I found my watch a week ago. （前面是过去式，用过去的时间）
4.His parents he...

都有问题

1.The door keeps opened.
The door is kept opened.
2.Jack is trying to helping me.
Jack is trying to help me.
3.I found my watch since a week.
I have found my watch since last week....

opened 改成 open 2 helping 改成 help 3 since 改成 after 4 in 改成 from 5 bought 改成 buy 6 worth 改成worthwhile 7 正确 8 rise 9 rose 10 already 改成 yet
