Do you know mint(薄荷)? It may be added into summer drinks to let us feel cool. Mint plays an important role in our daily life. It keeps our breath fresh and gives food and drinks a kind of fresh smell. But why is this little plant so popular with people?

Mint is found almost everywhere in the world, except in South America and Antarctica. There are 600 varieties of the plant, but a lot of them are so similar that even scientists have trouble telling the differences among them. What we have known for thousands of years, however, is that eating mint is good for our body health.

For starters, if people’s stomachs are not very comfortable, mint can be used to relieve(缓解) that uncomfortable feeling in people’s stomachs. That’s because of the acid(酸) that it contains. What’s more, if you have a common cold, drinking mint tea can reduce your sore throat.

While mint is safe to eat and used to treat people, it has its disadvantages. First of all, eating too much mint can be harmful. If you’re taking it for any health condition, don’t use it too much. Also, mint oil should not be used on the faces of children. This could cause breathing problems.

文章大意:本文主要讲述了动物有各自打招呼的方式,并介绍了黑猩猩、长颈鹿和海豚这三种动物打招呼的方式。

【推荐3】How do you greet your friends? People from different cultures may have different answers: shaking hands, nodding, kissing...But have you ever wondered how animals “say hello” to others?

We know how similar chimpanzees (黑猩猩) are to humans. It’s no surprise that their greetings are also close to ours. Chimpanzees usually greet each other with a hand touch, a hug or sometimes a kiss. Some of them can also communicate through simple sign language (手语).

Some animals seldom make loud sounds, for example, giraffes. Male giraffes often use their necks to greet each other. Their necks can reach up to two meters. When two giraffes meet, they may “shake” their necks and rub (摩擦) them against each other. This is to feel how strong and tall the other is.

Dolphins greet one another with whistles (哨叫声). They can hear other dolphins from many kilometers away. Every dolphin has a different whistle. It tells information about the dolphin, such as its age and health. When two groups of dolphins meet, they each choose a member of the other group to “talk” to. The two groups can then join up and travel together.

1. According to the text, chimpanzees may greet each other ________.
A.by saying “hello”B.by touching hands
C.through a real languageD.through a simple sound
2. What can we know about giraffes?
A.Giraffes often communicate mainly through loud sounds.
B.Giraffes greet each other by rubbing their noses together.
