Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

● Schedule yearly exams. 1. Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

● Protect against UV rays (紫外線). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. 2.

● Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. 3.Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

●4. As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (維生素) C and E help protect eyesight and promote eye health.

● Practice safe wear and care of contact lenses (隱形眼鏡). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. 5. Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

A. Eat your greens.

B. Eye care should begin early in life.

C. They can properly protect your eyes.

D. Stay in good shape by taking more vitamins.

E. Parents usually don’t care about their own eyesight.

F. Always follow the doctor’s advice for appropriate wear.

G. This frequent eye activity increases the risk for eye tiredness.

Buckingham Palace has a history that dates back over 500 years and has changed hands on numerous occasions, however, much of the building that remains standing today is from the original structure built in the early 1700's.

In the beginning Buckingham Palace was originally known as Buckingham House. However, in 1762 George III liked the house so much that he bought it for 28,000 and renamed it "The Queen's House". The reason for this was down to the fact that he bought the house to give to his wife Charlotte. Shortly after he did this, work soon began in order to remodel the house with the help of Sir William Chambers. This trend then continued with the accession of George IV in 1820 when he decided to reconstruct the house but he still used it for the same purpose that his father did.

One of the biggest physical changes to the house occurred several years later when the king had a change of mind. It was in 1826 that King George IV set about transforming the house into what it is known today, Buckingham Palace. He did this with the help of an architect known as John Nash.

The work that Nash carried out involved doubling the size of the main block through adding a new suite of rooms on the garden side facing the west. He then faced this with mellow Bath stone, which reflected the French neo-classical influence favored by George IV. Many of the rooms that Nash added still remain pretty much unchanged today.

The palace as it stands today acts as not only the London residence of Her Majesty the Queen but also the administrative headquarters of the Royal Household. It is in fact one of the few working royal palaces that remain in the world today. The state rooms are extensively used by the Queen as well as members of the royal family as a way of receiving and entertaining guests on state, ceremonial and official occasions.

1.George IV reconstructed Buckingham House probably to .

A. please his own wife

B. satisfy his son

C. sell at a good price

D. honor his old father

2.One of the biggest changes to Buckingham Palace took place in .

A. 1762 B. 1820 C. 1826 D. 1829

3.The last paragraph mainly tells us

A. how important Buckingham Palace is today

B. what Buckingham Palace is like today

C. some information of royal palaces in the world

D. how Buckingham Palace is used today

The Owl Count

Annie slept in the front of the seat with her father drove through the darkness. “We’re almost there!” Dad announced cheerfully. “Soon we’ll be observing and counting owls at the state park.” Yawning, Annie nodded and smiled. The time was 4:30 a.m. Looking out into the darkness, Annie remembered learning in school that most owls are active at night, when they hunt for food. During the day they sleep in hard-to-find spots.

“Dad, why do you need to count owls?” she asked. “It’s important for the scientists to have current information about bird populations,” he explained. “We want to know which birds have decreased in number and whether any new kinds of birds are coming into a certain area. You and I will write down the kinds of birds that we see today and keep a record of how many times we see each kind. Then we’ll send out a report to a scientific organization that is collecting about birds from people all over the country.”

Dad pulled into the parking lot of the state park. Then, with flashing in hand, they began their hike into the woods. Annie zipped up her coat and tried to keep from trembling. She had not expected the morning to be so cold. Luckily her gloves were in her pocket.

Suddenly Annie’s father stopped and gestured for her to be still. Obeying, Annie did not take another step. She thought she heard a low crying up head. “That’s certainly a screech owl,” her father whispered. “Let’s get a look at it.” After looking more closely, Annie could see that it was a small owl. Sensing danger, the owl narrowed its eyes and pulled its feathers tightly against its body. Annie carefully wrote down in her notebook that they had seen a screech owl.

Walking a little farther, they came to a tall oak tree. “This looks like a perfect spot to attract owls,” Dad said, “I’m going to play a recording of common call of the barred owl. Maybe we can get one to answer.’ Annie could hardly believe her ear. The recorded call sounded as if the bird were asking, “Who cooks for you?” Moments later Annie thought she heard a return call in the distance. She held her breath and waited. Suddenly a huge bird landed very quietly on a branch above them.

Annie had long forgotten how cold it was. She stood in wonder, shining her flashlight on the bird and studying it carefully. The barred owl was nearly two feet tall. Grey feathers surrounded its dark eyes. The bird did not stay long, but it did not matter. Annie would never forget the image of the powerful barred owl.

1.Why did Annie and her father go to the state park?

A. To take a hike in the woods.

B. To record the call of barred owl.

C. To collect information about birds.

D. To protect the environment for wildlife.

2.In paragraph 4, why did Annie’s father stop her suddenly?

A. He noticed a screech owl.

B. He heard somebody crying.

C. He sensed they were in danger.

D. He reminded her to take down note.

3.How did Annie feel when she saw the barred owl?

A. Bored B. Amazed C. Frightened D. Relaxed

Thirty-two people watched Kitty Genovese being killed right beneath their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one’s fellow man?

Not so, say scientists John Barley and Bib Fatane. These men went beyond the headlines to seek the reasons why people didn’t act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency.

Suppose you see a middle-aged man fall to the side-walk. Is he having a heart attack? Is he in a coma from diabetes(糖尿病)? Or is he about to sleep off a drunk?

Is the smoke coming into the room from a leak in the air conditioning? Is it steam pipes? Or is it really smoke from a fire? It’s not always easy to tell if you are faced with a real emergency.

Second, and more important, the person faced with an emergency must feel personally responsible. He must feel that he must help, or the person won’t get the help he needs.

The researchers found that a lot depends on how many people are around. They had college students in to be tested. Some came alone. Some came with one or two others. And some came in large groups. The receptionist started them off on the tests. Then she went into the next room. A curtain divided the testing room and the room into which she went. Soon the students heard a scream, the noise of file cabinets falling and a cry for help. All of this had been pre-recorded on a tape-recorder.

Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.

In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn’t. They do not feel any direct responsibility.

Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were emotional, they sweated, they had trembling hands. They felt the other person’s trouble. But they did not act. They were in a group. Their actions were shaped by the actions of those they were with.

1. The purpose of this passage is ____________.

A. to explain why people fail to act in emergencies

B. to explain when people will act in emergencies

C. to explain what people will do in emergencies

D. to explain how people feel in emergencies

2.The researchers have conducted an experiment to prove that people will act in emergencies when ____________.

A. they are in pairs B. they are in groups

C. they are alone D. they are with their friends

3. The main reason why people fail to act when they stay together is that ____________.

A. they are afraid of emergencies

B. they are unwilling to get themselves involved

C. others will act if they themselves hesitate

D. they do not have any direct responsibility for those who need help

4.The author suggests that ____________.

A. we shouldn’t blame a person if he fails to act in emergencies

B. a person must feel guilty if he fails to help

C. people should be responsible for themselves in emergencies

D. when you are in trouble, people will help you anyway
