【答案】B

【解析】

依据我国部分河流的特征来解答此题．

我国的长江有“黄金水道”“之称．长江古代时称“大江”或者“江”，发源于青藏高原的唐古拉山主峰各拉丹东的沱沱河，自西向东流经了11个省份，自上海东流入东海，长江长有6300公里，只次于非洲的尼罗河与南美洲的亚马孙河，居世界第三位，为中国的第一大河，流域的总面积为180多万平方公里，大约占全国总面积的五分之一；长江江阔水深，为我国南方之交通大动脉，当前长江的干支流的通航里程已达到9.6万公里，可以绕地球两圈半；年货运量大约占全国河流总运输量之70%，万吨巨轮可从长江上溯至南京，5000吨级的轮船可以开到武汉，3000吨级的可直至重庆．长江流域也拥有4亿亩肥沃的耕地，我国有3亿多人口生活于这儿，世界上还有哪一条江河能够哺育如此众多的人口，故以“黄金水道”称之，实在是当之无愧．故选B．

【题目】 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(中国食品药品监督管理局)．

The salted fish is produced with a large amount of salt, which later turns into nitrites(亚硝酸盐). 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(槟榔) 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.
