1. 2.

People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性癡呆癥), according to a recent study. 3. Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.

LakeLander ·2 hours ago

Today, a man talked very loud on his phone on a train between Malvern and Reading, making many passengers upset. I wonder how he would react if I were to read my newspaper out loud on the train. I have never had the courage to do it, though.

Why not give it a try? Perhaps you should take lessons on a musical instrument. The late musician Dennis Brian is said to have asked a fellow train passenger to turn off his radio. When his request was refused, he took out his French horn(號(hào)) and started to practice.

Angie O’Edema ·42 minutes ago

I don’t see how musical instruments can help improve manners in public. Don’t do to others what you wouldn’t like to be done to yourself. Once, a passenger next to me talked out loud on his mobile phone. I left my seat quietly, giving him some privacy to finish his conversation. He realized this and apologized to me. When his phone rang again later, he left his seat to answer it. You see, a bit of respect and cooperation can do the job better.

Now Hear This

What do former American president Bill Clinton and rock musician Pete Townshend have in common? Both men have hearing damage from exposure to loud music, and both now wear hearing aids as a consequence. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.

Temporary hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.

"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says a physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.

What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分貝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.

The facts are pretty frightening. But are rock bands turning down the volume? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather. "I wouldn't have it any other way. And neither would the real fans of rock. "

Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "

Levels of Common Noises

Normal conversation 50 — 65 dB

Food blender 88 dB

Jet plane flying above a person standing outside 103 dB

Rock band during a concert 110 — 140 dB

1.From Paragraph 1, we can learn that .

A. loud music is a major cause of hearing loss

B. famous people tend to have hearing problems

C. teenagers should stay away from school bands

D. the problem of hearing damage is widely known

2.In Paragraph 3, the underlined word "recondition" means .

A. not to be seen

B. to fill with sound

C. to become larger in size

D. to make good again

3.The purpose of the chart at the end of the article is to show .

A. a list of harmful sounds

B. the effect of rock concerts

C. the noise levels of familiar sounds

D. relationship between daily activities and hearing loss

4.Which of the following statements will Dr. Sam Levine probably agree?

A. When your ears feel warm, your hair cells are dead.

B. Drummer Andrew Sather gives good advice.

C. Many are taking the risk of losing hearing.

D. Doctors know how to cure hearing loss.

At thirteen, I was diagnosed（診所） with kind of attention disorder. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not.

In my first literature class, Mrs.Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said,”Mrs.Smith, you see, the doctor said I have attention problems. I might not be able to do it.”

She glanced down at me through her glasses, “you are no different from your classmates, young man.”

I tried, but I didn’t finish the reading when the bell rang. I had to take it home.

In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn’t get much education. But Louis didn’t give up. Instead, he invented a reading system of raised dots（點(diǎn)）, which opened up a whole new world of knowledge to the blind.

Wasn’t I the “blind” in my class, being made to learn like the “sighted” students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?

I didn’t expect anything when I handled in my paper to Mrs.Smith, so it was quite a surprise when it came back to me the next day- with an ”A” on it. At the bottom of the paper were these words:”See what you can do when you keep trying?”

1.The author didn’t finish the reading in class because.

A. He was new to the class

B. He was tried of literature

C. He had an attention disorder

D. He wanted to take the task home

2.What do we know about Louis Braille from the passage?

A. He had good sight

B. He made a great invention.

C. He gave up reading

D. He learned a lot from school

3.What was Mrs.Smith’s attitude to the author at the end of the story?

A. Angry B. Impatient

C. Sympathetic D. Encouraging

4.What is the main idea of the passage?

A. The disabled should be treated with respect.

B.A teacher can open up a new world to students.

C. One can find his way out of difficulties with efforts.

D. Everyone needs a hand when faced with challenges.

In 2012, the Tower of London welcomed two new inhabitants: a pair of ravens(烏鴉) named Jubilee and Grip． Their arrival celebrated the bicentenary(二百周年) of Charles Dickens’s birth． This Grip was the third of the Tower ravens to be named after the novelist’s own pet bird．One of his predecessors（前輩） was resident during World War Two; he and his mate Mabel were the only ravens to survive a bombing attack on the Tower．

Dickens’s Grip, who had an impressive vocabulary, appears as a character in the author’s fifth novel, Barnaby Rudge． On 28 January 1841, Dickens wrote to his friend George Cattermole: “my notion is to have [Barnaby] always in company with a pet raven, who is immeasurably more knowing than himself． To this end I have been studying my bird, and think I could make a very distinctive character of him．”

Unfortunately, just a few weeks after Dickens wrote that letter, Grip died, probably as a result of having stolen and eaten paint some months earlier． The bird had developed a strange habit – tearing sections off painted surfaces (including the family's carriage) and even drinking a quantity of white paint out of a tin． Dickens mourned his loss and wrote a humorous letter to his friend, the illustrator Daniel Maclise, about the raven’s death．

He related how, when Grip began to show signs of sickness, the vet was called and “administered a powerful dose of castor(蓖麻) oil”． Initially this seemed to have a positive effect and the author was thrilled to see Grip restored to his usual personality when he bit the coachman (who was used to the raven and took it in good humor)． The following morning, Grip was able to eat “some warm porridge”, but his recovery was short lived．

As Dickens wrote to Maclise, “On the clock striking twelve he appeared slightly upset, but soon recovered, walking twice or thrice along the coach-house, stopped to bark, exclaimed ‘Hello old girl’ (his favorite expression) and died．He behaved throughout with a decent manner, which cannot be too much admired．The children seem rather glad of it． He bit their ankles． But that was play．”

1.Which of the following is right about Dickens’s pet Grip?

A． he liked painting a lot．

B． he could speak English fluently．

C． he was quite ill before his death．

D． he and Mabel survived a bombing attack．

2.Why did Dickens study his bird Grip?

A． Because the bird was very strange looking．

B． Because Dickens liked the bird immeasurably．

C． Because Barnaby needs a companion who was always with him．

D． Because Dickens wanted to base one character of his novel on him．

3.What caused the death of Dickens’s Grip?

A． His old age．

B． His strange diet．

C． The killing of the coachman．

D． His bad habit of biting people．

4.Which of the following can be the best title of the passage?

A． A bird in a novel．

B． The writer’s bird．

C． The death of a bird．

D． Dickens and his bird
