【解析】
【1】由題目可知,該外國游客在短短的時(shí)間時(shí)感受了四季變化,說明他乘坐的路線是南北走向的鐵路線,東西走向的鐵路線可以感覺干濕狀況的差異,不能感受四季變化,以上四條鐵路線中,只有京哈-京廣符合題意,故選C。
【2】由題目可知,該游客在短短的時(shí)間里感受到四季的變化,說明此季節(jié)我國南北氣溫差異大,只有在冬季時(shí)才能體會到,其他季節(jié)我國南北溫差小,故選D。
【3】由題目可知,該游客在短短的時(shí)間里感受四季變化,并且十分奇怪,說明該游客的家鄉(xiāng)四季變化小,以上四個(gè)國家,美國四季變化大,冰島、埃及和新加坡的四季變化小,可以判斷該游客最不可能來自美國,故選A。
【4】由題意可知,該游客在不登高的情況下,短短十幾天感受四季的變化,這是由于我國南北跨緯度廣,冬季時(shí)南北氣溫差異大,與地形、海陸、洋流因素?zé)o關(guān),故選B。
本題考查我國南北氣候差異大的特點(diǎn)及原因。

【題目】 The salted fish is a 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 make you suffer from cancer more easily. 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, many foods that we often eat 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 because of eating them. Cancer is caused by many different factors, such as one's genes, environment, lifestyles and eating habits. As long as one has a balanced diet, he doesn't need to avoid cancercausing foods entirely.
說明:21題完成句子;22~23題簡略回答問題;24題找出并寫下全文的主題句;25題將文中畫線句子譯成漢語。
【1】The salted fish ________________ lots of salt, which later turns into nitrites.

________________________________________________________________________
【3】How many factors that may cause cancer are mentioned in this passage?
