Question

【題目】閱讀理解

Bad breath, or halitosis(口臭)， can be a serious problem.
Bad breath is caused by some germs(細菌) that grow in the month. When you don't brush in a right way, germs will leave between your teeth and make your breath smell bad. Certain foods, especially ones like garlic and onions can cause bad breath. Smoking can also make bad breath.
Some people say that mouthwash(漱口水) will make bad breath go away, but it isn't true. It only stops bad breath for a short time.
Some people also say that if you brush your teeth, you will not have bad breath. But the truth is that most people only brush their teeth for 30 to 45 seconds. It just doesn't work. To clean all your teeth, you should brush for at least 2 minutes and at least twice a day. Remember to b rush your tongue, too—germs love to stay there.
If you do brush properly, but your bad breath still exists, visit your dentist for cleanings. You may have a medical problem like germ disease.
If you don't want to have bad breath, make sure you're taking care of your teeth and month well.

【解析】文章大意：這篇短文給我們介紹了口臭的原因以及如何防止口臭，短文中的作者給我們糾正了人們的一些錯誤做法，講解了正確的做法。
（1）細節(jié)理解題。根據(jù)短文第一段中Bad breath is caused by some germs(細菌) that grow in the month …Certain foods, especially ones like garlic and onions can cause bad breath. Smoking can also make bad breath可知，口腔里的一些細菌、某些食物，還有吸煙都可以導致口臭。故選A。
（2）詞義猜測題。根據(jù)Certain foods, especially ones like garlic and onions can cause bad breath可知，garlic應該跟后面的名詞onions是同一類的食物，能導致口臭，因此在這四個選項中B選項大蒜是可以導致口臭的，故garlic的意思是大蒜，故選B。
（3）細節(jié)理解題。根據(jù)短文中But the truth is that most people only brush their teeth for 30 to 45 seconds可知，大多數(shù)人刷牙的時間是30到45秒鐘。故選C。
（4）細節(jié)理解題。根據(jù)短文中To clean all your teeth, you should brush for at least 2 minutes and at least twice a day.可知，想要清潔牙齒，我們刷牙的時間應該在至少兩分鐘，一天至少兩次。故選B。
（5）推理判斷題。根據(jù)短文中If you do brush properly, but your bad breath still exists, visit your dentist for cleanings. You may have a medical problem like germ disease可知，如果適當刷牙，你的口臭仍然存在，這可能是有醫(yī)學問題，由此可知B是正確的。根據(jù)短文中Some people say that mouthwash(漱口水) will make bad breath go away, but it isn't true. It only stops bad breath for a short time可知A不對；根據(jù)Remember to brush your tongue, too—germs love to stay there可知C不對；根據(jù)If you do brush properly, but your bad breath still exists, visit your dentist for cleanings可知D不對。故選B。
