A.寒潮、洪澇是影響我國長江流域的重要天氣災害

B.臺風是冬春季節(jié)影響我國南部沿海地區(qū)的一種重要的氣象災害

D.干旱是我國夏秋季節(jié)發(fā)生頻繁、損失嚴重的氣象災害

【答案】A

【解析】

本題主要考查我國自然災害的分布。

我國是一個自然災害頻發(fā)的國家,寒潮主要發(fā)生在我國大部分地區(qū)的冬季,是我國北方地區(qū)、西部地區(qū)、長江流域等地區(qū)重要的氣象災害,洪澇是影響我國長江流域的重要天氣災害,所以A正確;臺風是夏秋季節(jié)影響我國南部沿海地區(qū)的一種重要的氣象災害,所以B錯誤;寒潮、沙塵暴對我國北方地區(qū)和西北地區(qū)造成的危害最大,所以C錯誤;干旱是對中國農業(yè)生產影響最大、最常見且分布范圍最廣的一種自然災害,夏秋季節(jié)降水多,干旱發(fā)生的少,所以D錯誤。故選A

【題目】 The salted fish is a kind of popular food in the south of China. It is delicious and adds a salty flavor to other dishes. But eating too much salted fish can give you cancer. We can see it clearly on the list of cancercausing foods, which was recently published by the China Food and Drug Administration(中國食品藥品監(jiān)督管理局)

The salted fish is produced with a large amount of salt, which later turns into nitrites(亞硝酸鹽). When nitrites reach our stomach, they turn into another kind of chemical that can cause cancer.

So does this mean we can't eat salted fish anymore?

“People don't need to worry too much. Cancer is concerned with how often you eat certain foods and how much of them you eat,” Huang said. If you really like eating salted fish, you can eat a small amount once or twice a month. Meanwhile, you should also eat more fruit and vegetables that are rich in vitamin C, as this can help to prevent the formation of nitrites.

In fact, there are many foods that we often eat that are thought to cause cancer, such as pickles(咸菜), areca palms(檳榔) and so on.

Although these foods may bring cancer, it doesn't mean a person will get cancer just from eating them. Cancer is caused by many different factors, such as one's genes, environment, lifestyle and eating habits. As long as one has a balanced diet, he doesn't need to avoid cancercausing foods entirely.
