Make sure he’s warm. 确保他不受凉。 make sure的意思是“确保，保证”。如： Make sure you turn off all the lights before you go out. 在出门之前一定要把所有的灯都关掉。 I think I locked the door, but I’ll go hack and check, just to make sure. 我觉得我锁上门了，但我还是要回去看看，确认一下。 4. That’s such good advice that you could be a doctor, 这个建议非常好，你都可以当医生了！ such... that...这个句型表达“如此……以至于……”的意思，such后面接名词，名词前可以有形容词修饰。如果只有形容词或副词，则要使用so...that...这一句型。如: It is such a tiny kitchen that only one person can cook in it. 这个厨房很小，只能容下 一个人在里面做饭。 They are such nice people that we all like them. 他们人很好，我们都喜欢他们。 He urn so weak that he could hardly stand up. 他很虚弱，几乎站不起来。 Everything happened so quickly that I hadn’t time to think. 一切发生得太快 了，我都 没有时间思考。 5.

Can it be your brother? 是谁送来的礼物啊？ 会是你哥哥吗？ （询问 可能性） It must be your brother. I saw him in your room just now. 肯定是你哥哥，我刚才看见他在 你的房间里。 （语气强烈，表示非常肯定） It cant be my brother.
