We all know that if we want to keep our body in good shape we have to do physical exercise regularly as well as be careful with what we eat. What we tend to forget is that this goes for our eyes as well. Medical science confirms that a diet rich in carotenoids (类胡萝卜素) can help maintain good vision(维持好视力) and prevent against a number of eye diseases. Here's some advice about how to choose the right diet to keep your eyes healthy.
— Eat orange food. Fruits and vegetables with orange flesh are rich in carotenoids. In addition to carrots,oranges,pumpkins and sweet potatoes are also available. All of these contain high levels of carotenoids,which help to maintain good vision.
— Include dark green vegetables,such as spinach (菠菜) and broccoli (西兰花) in your diet, to act as natural sunglasses. Recent scientific studies have shown that these vegetables can help block (阻挡) the damaging UV radiation(紫外线辐射)from the sun's rays.
— Prevent some eye diseases with orange juice, yellow corn, whole milk, nuts and leafy vegetables. These foods are good sources of vitamins A, C, D and E. All of these are necessary to good eye health.
— Increase your intake of omega¬3 with some sea fish, and some other seafood. Omega-3 helps build cell walls and is especially beneficial to keeping eyes healthy .It also helps regulate the eye's internal pressure and helps the eye dry up excess fluid.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风)within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.The text mainly discusses the relationship between.
A.heart problems and air quality |
B.heart problems and exercising |
C.heart problems and smoking |
D.heart problems and fatty food |
The underlined word “modest” in Paragraph 3 most probably means.
A.relatively high | B.extremely low |
C.relatively low | D.extremely high |
What can we learn from the text?
A.Eating fatty food has immediate effects on your heart. |
B.The EPA conducted many studies on air quality. |
C.Moderate air quality is more harmful than smoking, |
D.Stricter regulations on pollutants should be made. |
The author’s purpose of writing the text is most likely to.
A.inform | B.persuade | C.describe | D.entertain |
Three Boys and a Dad
Brad closed the door slowly as Sue left home to visit her mother. Expecting a whole day to relax, he was thinking whether to read the newspaper or watch his favourite TV talk show on his first day off in months. “This will be like a walk in the park,” he’d told his wife. “I’ll look after the kids, and you can go visit your mom.”
Things started well, but just after eight o’clock, his three little “good kids”—Mike, Randy, and Alex—came down the stairs in their night clothes and shouted “breakfast, daddy.” When food had not appeared within thirty seconds, Randy began using his spoon on Alex’s head as if it were a drum. Alex started to shout loudly in time to the beat(节拍). Mike chanted “Where’s my toast, where’s my toast” in the background. Brad realized his newspaper would have to wait for a few seconds.
Life became worse after breakfast. Mike wore Randy’s underwear on his head. Randy locked himself in the bathroom, while Alex shouted again because he was going to wet his pants. Nobody could find clean socks, although they were before their very eyes. Someone named “Not Me” had spilled a whole glass of orange juice into the basket of clean clothes. Brad knew the talk show had already started.
By ten o’clock, things were out of control. Alex was wondering why the fish in the jar refused his bread and butter. Mike was trying to show off his talent by decorating the kitchen wall with his colour pencils. Randy, thankfully, appeared to be reading quietly in the family room,but closer examination showed that he was eating apple jam straight from the bottle with his hands. Brad realised that the talk show was over and reading would be impossible.
At exactly 11:17, Brad called the daycare centre (日托所).“I suddenly have to go into work and my wife’s away. Can I bring the boys over in a few minutes?” The answer was obviously “yes” because Brad was smiling.When his wife left home. Brad expected to.
A.go out for a walk in the park |

Which of the following did Randy do?
A.Drawing on the wall | B.Eating apple jam |
C.Feeding the fish. | D.Reading in a room |

What brings a nation together? Of the four choices — shared values, language, history, and religion, it’s shared values. In our latest poll (民意调査), seven out of 16 countries chose values as the greatest factor (因索)bringing a nation together, and six preferred language. Both choices scored high in the poll, suggesting that our values and how we express them are closely linked Still, history was not forgotten in some countries, particularly in Mexico and Russia. Even Canada and the United States chose national histories as the second-most important factor uniting their people. The biggest surprise? Not one country picked religion as its top choice.
Respect your elders In most countries, the oldest generation considered values more important to a nation than did those who are under 45 years old. |
Do you speak Canadian? Language scored lower in Canada than in all other countries polled, perhaps because the country speaks two official languages, French and English. |
Church and state Most people polled do not connect their religious beliefs to their national pride. Religion ranked last in 13 countries — with France scoring it at 1%, the lowest of all. |
According to the poll, what was the most important factor in bringing a nation together?
A.Language. | B.Values. | C.History. | D.Religion. |
In which country did language score the lowest in their national pride?
A.Canada. | B.Mexico. | C.France. | D.America. |

阅读下面短文,并根据短文后的要求答题(请注意问题后的字数要求)。
[1]If you are worried about things and are under a lot of stress at work or school,then you are prob-ably not sleeping well. Worry can keep you awake,tossing and turning in bed until the early hours of the morning when you eventually fall asleep. When you wake up,you don't feel refreshed,but tired and worn out and unable to face a new day.
[2] Dr. Henry Winkle,in a recent newspaper article entitled Stress and Sleep,indicates that .Dr. Winkle says,“The more we worry,the less we sleep,the more we are unable to deal with stress. If we can find a way to get a good night's sleep,”he adds,“we can often find the energy to deal with what's worrying us.”
[3]So,what is a good night's sleep? Research shows that the amount of sleep which people need in order to keep healthy varies a lot. Seven hours is about the average amount,though strangely enough,sleeping longer often gives you a headache instead of making you feel more refreshed.
[4]Dr. Winkle believes that preparing for sleeping is important. People who work late should try to give themselves a short break and do something restful before going to bed. This could be watching TV or listening to music. Doing some exercise earlier in the day should help you to feel physically as well as mentally tired. A bedtime drink can also help,but coffee or tea should be avoided as they contain caffeine and will keep you awake.
[5] “When you put the light out,” Dr. Winkle says,“concentrate on relaxing your muscles,working slowly up from your feet,and you 'll be asleep before you know it.”What is the main idea of the text? (no more than 5 words)
Complete the following statement with words from Paragraph 2. ( no more than 3 words)
People shouldn't go to sleep immediately but shouldafter working late in the night.Point out the disadvantage of drinking coffee and tea before going to bed. (no more than 6 words)
Fill in the blank in Paragraph 2 with proper words. (no more than 10 words)
What does the word “it” (Line2,Paragraph5) probably refer to? (no more than 3 words)
In a few years,you might be able to speak Chinese,Korean,Japanese,French,and English-and all at the same time. This sounds incredible,but Alex Waibel,a computer science professor at US's Car-negie Mellon University (CMU) and Germany's University of Karlsruhe,announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other.
One application,called Lecture Translation,can easily translate a speech from one language into an-other. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Us-ers also have to be trained how to use the programme.
Another machine can send translations of a speech to different listeners depending on what languagethey speak. “It is like having a simultaneous translator right next to you but without disturbing the person next to you,”Waibel said
Prefer to read? So- called Translation Glasses transcribe(转录) the translations on a tiny liquid-crystal display(LCD) screen.
Then there's the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech.The electrodes could be replaced with wireless chips implanted in a person's face,according to research-ers.
During a demonstration held last Thursday in CMU's Pittsburgh campus,a Chinese student named Sang Jun had 11 tiny electrodes attached to the muscles of his cheeks,neck and throat. Then he mouthed-without speaking aloud- a few words in Mandarin(普通话) to the audience. A few seconds later,the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: “Let me introduce our new prototype.”
This particular instrument,when fully developed,might allow anyone to speak in any number of lan-guages or,as Waibel put it,“to switch your mouth to a foreign language”. “The idea behind the universi-ty's prototypes is to create'good enough' bridges for cross- cultural exchanges that are becoming more common in the world,”Waibel said.
With spontaneous(自发的) translators,foreign drivers in Germany could listen to traffic warnings on the radio; tourists in China could read all the signs and talk with local people;leaders of different coun-tries could have secret talks without any interpreters there.What can't be learned from the text?
A.The spontaneous translators will help us a lot. |
B.There is no Muscle Translator in the world now. |
C.Muscle Translators can translate what you think into speech if you just move your mouth. |
D.A lecture translation can translate what you said into other languages easily. |
What does the underlined word mean?
A.happening at at the same time. | B.happening by itself. |
C.similar in size. | D.Similar in quality. |
What's the final destination of inventing the language translators?
A.To make cultural exchanges between different countries easier. |
B.To help students learn foreign languages more easily. |
C.To make people live in foreign countries more comfortably. |
D.To help people learn more foreign languages in the future. |
What can be inferred from the seventh paragraph?
A.The translator is so good that it can translate any language into the very language you need. |
B.The translator is becoming more and more common in the world as a bridge. |
C.With the help of the translator,you only need to open your mouth when you want to say something without saying the exact words at all. |
D.The translator needs to be improved before being put into market. |
Where can we probably find this passage?
A.A newspaper. | B.A magazine on science. |
C.A fairy tale. | D.A scientific fantasy book. |
