1.Tell him to come to my office.
让他来我办公室一下.
你的:Tell him to come into my office英语中没有这个用法,语法正确不一定就有人说,如果用中文翻译就是:让他进我办公室里面来(不要在外面,外面冷)
2.We climbed up to the top of the mountain.我们爬到山顶.
你的:We climbed on the top of the mountain.也是语法正确
我们在山顶上爬,你觉得逻辑没有问题吗?
3.Please bring the cup into the kitchen for me.
请帮我把杯子拿到厨房.
你的:Please bring the cup in the kitchen for me.
请帮我把厨房的杯子拿来.也是语法没有错误,但可能与实际情况不答吧,一般bring要接to之类的方向词,而in则是位置,不是方向
