It runs a register of environmental causes of cancer which runs from Group 1, where the evidence is convincing, to Group 4, where there's no risk. Since 1991, coffee has been in category 2B reflecting a possible link to cancer. Now it's switched to category 3, which means there no conclusive evidence of a cancer risk. The review concludes very hot beverages probably do cause cancer. Experts have urgedpeople to let their drinks cool down for a few minutes. 词汇表reclassify 把……再次分级别 review 审查,研究 register 册子 convincing 有说服力的 reflecting 显示出,反映出 conclusive 确定的,确凿的 beverages 饮料 urged 敦促,利权

P: Thanks for going skiing with me today, Yang Chen. Y: Of course, Patrick! 我也喜欢滑雪。而且啊,seeing you crash and burn sounds like a lot of fun. P: Thanks. But before we go, I should tell you some safety rules. Skiing can be dangerous if you don't know what you're doing. For example, an avalanche could kill you. Y: 你是说雪崩? P: Exactly. Actually, you can use the word 'avalanche' any time there is a lot of something. For example, the politician received an avalanche of criticism when it was revealed he had taken bribes. Y: 就是说很多人批评他。可是Patrick, 这里只是一个小山坡 不可能发生雪崩。 P: Alright, maybe not. But you can fall and get hurt too if you don't know what you're doing. Whoa! Did you see that little kid crash? That was a total yard sale! Y: Patrick! 小孩儿摔倒了你干嘛幸灾乐祸。 P: But you said its funny to watch some people crash and burn. Y: I said watching you crash and burn. 你刚才为什么说 it was a total yard sale? P: Well if you have a bad crash, and all your equipment gets spread out in the snow, it looks like you're having *a yard sale. Y: Aha, I get it. 因为摔得很惨, 滑雪的家伙摊了一地,好像卖旧货一样。Very funny. P: As funny as watching me crash? Y: Mmm, I don't know. Let's find out. P: All right. Here I go? Y: Hi, can I buy that? P: I'm not selling anything! Y: My apology. I thought you are having* a yard sale.
