some times we gave dinner in the restaurant .哪里错了?

更正一楼答案,保证准确率!
1.some times 改成 sometimes
some times 意思是“有几次”,而sometimes意思是“有时”
2.watch 改成 watching 或 to watch（第一个改法更佳）
like doing sth 类似于 like to do sth,意思是“喜欢做某事”
3.去掉be
前面的is本来就是be动词,所以后面的be多余
4.watches 改成 watch
句子为一般现在时,而主语the twins为第三人称复数不是单数,所以谓语动词不能用单数形式watches,改成原形watch即可

gave-give
watch-watching
is去掉
watches-watch

Sometimes we have dinner in the restaurant.
some times 是指几次 sometimes是指有时候 有一定的区别
He does not like watching TV at home.
只有like dong sth. 或者 like to do sth. 两者都是喜欢做某事的意思 没有like do sth.
