【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.

1題完成句子；2～3題簡略回答問題；4題找出并寫下全文的主題句；5題將文中畫線句子譯成漢語。

【1】The salted fish ________ lots of salt, which is delicious and has a salty flavor.

【2】What can be helpful to you if you eat the salted fish?
