【题目】How to Improve Eyesight Naturally

Eyes are important for everybody. You must take care and try everything in your hand to keep them in good condition. Here are some of the tips to improve your eyesight naturally.

1

Strain is known to be a factor in many health conditions and eyestrain is no exception. Try meditation, yoga or other methods of stress relief to improve your vision and overall health.

Try palming.

Sit upright in a comfortable chair.2 Cup your hands so that there is no pressure on your eyes. Let your fingers rest across your forehead. There should be no light entering your eyes. Palming should be done for a period of 5 to 10 minutes to start. Palming should be relaxing. It may help to do palming in a darkened room.

Avoid sugar as much as possible.

3 It will unpleasantly affect your eyesight, which affects the eyes by producing a larger amount of insulin (胰岛素) in the blood. Therefore you shouldn’t be having much fruit juice or something that contains a lot of sugar.

Exercise your eyes.

The only exercise most eyes get is that daily rubbing we give them when we’re tired or suffering from eyestrain. But eye exercises are actually good for your eyes and can improve your vision.4 Blink as fast as you can for a few seconds then close your eyes tightly, open and repeat. Do this exercise 3 to 4 times daily.

Eat healthy.

You probably hear that statement all the time but eating the right foods are necessary to good health.5 Foods that are high in fiber, vitamin C, D and beta carotene as well as other vitamins and minerals can help improve your vision. Here are a few foods that can be beneficial to good vision: carrots, eggs, blueberries, spinach, kale, grapes, and fresh garlic.

A. Reduce eyestrain.

B. Keep your eyes moist.

C. Sugar is your eyes’s worst enemy.

D. Give your eyes a workout with the following exercise.

E. You may not be aware that your diet affects your vision but it does.

【题目】We talk about people being “colour-blind” but very few of us are. Even those who describe themselves as colour-blind are normally just colour lack. A strongly, colour-blind person will still be able to tell 20 different colours, compared to the 100 or so that normal-sighted people see.

Pingelap, a tiny island in the Pacific, is a beautiful spot but one that has a’ genetic trouble. It is known as Colour-blind Island because so many people who live on this remote island can only sec in black and white.

Not being able to see in colour is bad enough. But one is lander, Herrol, who’s a fisherman, also struggles in full sunlight because all he sees is a painful burnt-out image. “I find it difficult to go outside in the sun,” he says, “because when it’s sunny I cannot see to do my work.”

But if being truly colour-blind is rare, why is it that around 10% of the population of Pingelap live in a totally black and white world?

Well,we know that in 1780 the population of Pingelap was all but wiped out by a tsunami (海啸). As few as 20 people survived, one of whom was the king. It’s believed he had a genetic fault that causes colour-blindness and he passed this fault on to his many generations.

There is one advantage. Herrol can see well, really well, in the dark. So when it gets dark, Herrol and his friends get in their boats and hunt flying fish. They hang up flaming torches and the fish are attracted to the flames. “This type of fishing is fun,” Herrol says, “especially if we catch plenty. So even though it’s hard work we enjoy it.”

1What is Pingelap famous as?

A. A tiny island.

B. A beautiful island.

C. A mentally troubled island.

D. A colour-blind island.

2What .can we infer about Herrol?

A. He may stay at home when it’s sunny.

B. He is interested in burnt-out images.

C. He likes taking photos very much.

D. He doesn’t live in Pingelap any more.

3Why are about one-tenth of people in Pingelap seriously colour-blind?

A. Because Pingelap often suffers from tsunamis.

B. Because the king had an unlucky marriage.

C. Because the king’s genetic fault played a role.

D. Because the king made a serious mistake.

4What would be the best title for the text?

A. The island of colour-blindness.

B. The disadvantage of Herrol.

C. The history of Pingelap.

D. The advantage of colour-blindness.

【题目】 As William Shakespeare is to literature in English, so is the poet Du Fu to the Chinese literary tradition. “We have Dante, Shakespeare and Du Fu. These poets create the very values by which poetry is judged,” said Harvard Professor Stephen Owen in Du Fu, China’s Greatest Poet, a new BBC documentary(纪录片) broadcast on April 7.

Aimed at introducing the charm and beauty of traditional Chinese literature to viewers around the globe, the documentary invited famous British actor Ian McKellen, who played the wizard(巫师) Gandalf in the film series The Lord of the Rings, to read 15 of Du’s poems that have been translated into English.

The one-hour film talks about the poet’s life experiences in detail. Born in 712, Du lived under the government of the Tang Emperor Xuanzong (713-756), a time marked by extraordinary prosperity(繁荣), inclusiveness (包容) and cultural achievement. However, as the An Lushan Rebellion of 755 broke out in the country, Du, the former civil servant(文职人员) at the Tang court, had to take his family on the road as refugees(难民), and put up with starvation and suffering. Through ups and downs, the poet never stopped writing and about 1,500 poems have been kept over the ages.

“Chinese people really value the recording of history and Du is better than anyone at reflecting(反映) history in his poetry. That’s because historical events are mirrored in his own life and spiritual journey,” Zeng Xiangbo, a professor of ancient Chinese literature at Renmin University of China, told China Daily.

Even though he never held a high position in the government, Du still cared about common people. For example, in the poem My Cottage Unroofed By Autumn Gales , he wrote that “Could I get mansions covering ten thousand miles, I’d house all scholars poor and make them beam with smiles. ” “That’s why he was honored as a Poet Sage by later generations. A difficult life and his spirit of concern about the world helped him create so many masterpieces,” Shi Wenxue, a cultural critic based in Beijing, told the Global Times.

1According to Para.2, we know Ian McKellen is___________.

A.a narrator in the documentaryB.a big fan of Du Fu

C.the director of the documentaryD.a British wizard

2Why Du Fu is so valuable a poet in the mind of Chinese people?

A.Because he experienced the ups and downs of Tang Dynasty.

B.Because he never stopped and wrote about 1,500 poems.

C.Because his poems are completely kept over the ages.

D.Because his poetry is a good reflection of history.

3The poem mentioned in the last paragraph is intended to _________.

A.explain Du Fu’s position in the government

B.show Du Fu’s concern about ordinary people

C.tell the readers what a difficult life Du Fu lived

D.show Du Fu’s intelligence in writing a poem

4What is the passage mainly about?

A.Du Fu’s works gain popularity home and abroad.

B.Chinese literature becomes a hit in the UK.

C.China’s Poet Sage appears on the screen in the UK.

D.British people fall in love with Chinese poetry.

In South Korea smartphone cases come with rings fixed on the back 1 (prevent) clumsy owners from dropping them. This makes people look like they are married to their phones.

Walk around the streets of Seoul, and there is 5 real risk of bumping into people 6 eyes are glued to their smartphone screens. According to the statistics, around 370 traffic accidents annually 7 (cause) by pedestrians using smartphones.

The government initially tried to fight the “smombie” (手机僵尸) phenomenon by distributing hundreds of stickers (贴纸) around cities, 8 (beg) people to “be safe” and look up.

【题目】Directions: After reading the passage below, fill in the blanks with the proper forms of the given worlds to make the passage coherent and grammatically correct.

Having nothing to write about is, perhaps, the greatest fear of a student about to begin an essay for an IELTS or TOEFL test. However, critical thinking isn’t such a difficult skill to master. In fact, many of you will have already used this valuable skill in your life.

Suppose one of your friends recommends a movie by saying ,“It’s a really wonderful movie and definitely worth 1 (watch).”,Instead of simply taking the recommendation, you may ask the question“Why is it wonderful?”By doing this you are thinking critically. A more professional term to define this process 2 (call) identifying ambiguity, which is regarded as the key stage in thinking critically.

Let’s look at following examples from IELTS Writing Task.

Detailed description of crimes on newspaper and TV have consequence for society, so this kind of information should be restricted in the media. To what extend do you agree or disagree with this statement.

To think critically, the fist thing 3 (consider) isn’t whether you agree or not. You should instead try to clarify the words “detailed description of crimes” by asking yourself 4 these details might be. Then you should come up with a list like this :

1.Investigating the target victim before the crime

2.Measures to avoid 5 (track)by the police

3.Bloody crime scenes.....

After that ,it won’t be hard for us to groups these details, leading eventually to two paragraphs: some disclosure of information may allow people to protect themselves from crime. However,it is not appropriate for many other details 6 (release)to the general public.

Practice identifying ambiguity when you write the essay.Your work will definitely leave a good impression on your teachers.
