On the level of everyday usage a myth is a false story or belief. A myth is something that is not correct, but many people believe. There are a lot of myths about the human brain.

One of the biggest myths is that we only use 10 percent of our brains. The next part of the myth is that if we can learn to use the rest of our brains, then we’ll be much smarter. People say this all the time, but it’s absolutely not true! The truth is that although we don’t know everything about the human brain, we know that each part of it has an important function (功能). Modern scientists think the “10 percent myth” ridiculous (荒謬的).

The other most popular myth is about being “right brained” or “l(fā)eft brained”. According to this myth, people who use the right side of their brains are more artistic and creative. People who use the left side of their brains are better at math and science. This is as popular as the 10 percent myth, and it’s also wrong. In 2013, a study at an American university examined the right brain and left brain myth. According to the study, we use both sides of our brains equally (相等地).

It’s true that we use different parts of our brains for different things. We use our left side for language more, and our right side when we need to pay attention. But there is no evidence (證據(jù)) that creative people use the right side more, or that scientific people use the left side more.

We’ve talked about myths, so let’s look at a few interesting facts about the brain. First of all, the brain feels no pain. Second, about 75 percent of the brain is made of water. It’s also the fattest organ in your body. Here’s another interesting fact about the brain. Around the time you turn 18 years old, it stops growing.

1.What do modern scientists think of “10 percent myth” of the brain?

2.What does the underlined word “This” in Paragraph 3 refer to?

3.May Robert, who is learning English, use the right brain more or the left brain more?

4.According to the facts mentioned in the passage, when does the brain stop growing?

5.What is the passage mainly about?

Is there a connection between music and language? According to recent studies, the answer is yes: Music helps develop certain language abilities in the brain.

A study from Northwestern University shows that playing a musical instrument can improve a person's hearing ability. As a part of the study, two groups of people listened to a person talking in a noisy room. The people in the first group were musicians, while those in the second group had no musical training. The musicians were found to be able to hear the talking person more clearly.

Musicians hear better, says study leader Nina Kraus, because they learn to pay attention to certain sounds. For example, when the violinists play in an orchestra（管弦樂隊）, they must listen closely to what they are playing and ignore(忽視)the other sounds. In this way, musicians can hear certain sounds better, even in a room with lots of noise.

Gotfried Schlaug, a doctor at Harvard Medical School, works with stroke(中風(fēng))patients.

Because of their illness, these people cannot say their names, addresses, or other information normally However, they can till sing. Dr. Schlaug was surprised to find singing words helped his patients finally speak. Why does this work? Schlaug isn't sure. Music seems to be able to make different parts of the brain active, including the bad parts. In some way, this helps patients use those parts of the brain again.

So music is not only enjoyable, but also good for us in many other ways. Playing an instrument or singing, says Nina Kraus, can help us do better in school and keep our brain sharp as we get older.

1.What were the people in the first group asked to do in the study of Northwestern University?

A.Listen to different kinds of music. B.Make some noise in an empty room.

C.Give the second group musical training. D.Find out what the talking person was saying.

2.The writer uses the example of violinists in Paragraph 3 to explain________.

A.how musicians play in an orchestra B.how musicians ignore certain sounds

C.why musicians have better hearing ability D.why musicians are not afraid of loud noise

3.Gottfried Schlaug helps his stroke patients speak by________.

A.playing music for them B.getting them to sing words

C.teaching them to play instruments D.joining the bad parts of their brain

4.What is the main purpose of the passage?

A.To introduce different ways of playing music.

B.To give some advice about making our brain active.

C.To show the relationship between music and language abilities.

D.To share the results of recent studies on treating stroke patients.

It’s been nearly 40 years since I became a member of the navy (海軍). You may be wondering how I have won so many honors as a commander-in-chief (最高統(tǒng)帥). In fact, it all began from the half a year’s basic training, which I will never forget. The training included midnight swims in the cold water, days without_________and long painful runs in the soft sand. I always felt cold, wet, hungry and painful.

The training also needed to find those who could_________in an environment of stress, mess, failure and hardships. To me, the basic training was a lifetime of challenges that lasted six months. And today, I’d like to talk about one little thing.

Every morning in the training, my instructors (教官) would appear in our rooms. The first thing they did was to_______our beds. The corners would be square if we did it right. The covers would be pulled tight, and the pillow would be centered just under the headboard.

It was a difficult task. But every morning we were required to make our beds_________. It seemed a little funny, but the wisdom of this simple act has been proved to me many times over.

If you make your bed every morning, you will have completed the first task of the day. It will bring you a small_________of success, and it will encourage you to do another task, and another and another. And by the end of the day, one task completed will have turned into many tasks completed. Making your bed will prove the fact. If you can’t do the_________things right, you will hardly be able to do the big things right.

Changing the world can happen anywhere and anyone can do it. I can make sure that it doesn’t matter whether I ever _______ a day in uniform (制服,軍服). Even now, I still start my day with making the bed to perfection. So if you have an awful day by accident, you will come home to a bed that is made—that you made—and a made bed gives you encouragement that tomorrow will be better.

In general, if you want to change the world,_________off by making your bed. I hope all of you will have a brighter future!
