8 . There are 8.8 million blind people in India. In fact, there are 36 million blind people worldwide and a quarter of them are in India; however, many cases of blindness in India are curable. The poor in India have limited access to primary eye healthcare and often do not eat foods rich in micronutrients, like vitamins and minerals, which play an important role in maintaining good eye health.

Many people worldwide are not even aware that they may have a vision (视力) problem simply because they do not get their eyes tested every year with a doctor, who tests for the functioning of the eye muscles (肌肉), as well as common diseases like night blindness. This exam is strongly recommended by experts because some changes in vision, which the patient may take longer to notice, can be found easily in this way.

Certain simple changes in diet and lifestyle can ensure better eye health for you. These include drinking plenty-of water, not smoking, and eating brightly colored and leafy fruit and vegetables. Wearing sunglasses protects your eyes from the sun, which damages otherwise healthy eyes. Learn about your family's eye disease history, and be on the lookout for any problem about your vision. Make sure that you see a doctor immediately for early intervention(干预) if you see any of these signs of worsening eye health.

            If you or a loved one needs to cure blindness or other eye diseases, turn to a crowdfunding (众筹) platform. A group of eye health caregivers have fundraised with crowdfunding platform Impact Guru to raise money to perform operations on the eyes of blind women in south Asia. Running an online fundraiser enables both doctors and patients to find a way out of the dark. If you want eye care to develop, start a fundraiser today.
1. Why are there so many blind people in India?

2. What does the author suggest in Paragraph 2?

A．Examining your eyes annually.

3. Which of the following may do harm to your eyes?

A．Smoking a lot.	B．Wearing sunglasses.
C．Drinking much water.	D．Watching brightly-colored pictures.

4. What does the author want to show in the last paragraph?

A．How to start a fundraiser online.

B．The importance of raising money.

C．The role of crowdfunding in eye care.

D．What should be done to raise money.

9 . One in five people carry a “smart gene” variant (变体) linked to long lifespan, bigger forebrains and enhanced mental ability, researchers have found.

“We’ve known for a long time that people lose cognitive (认知) abilities as they age, but now we’re beginning to understand that factors like KLOTHO can give people a boost in aging. Genetic variation in KLOTHO could help us predict brain health and find ways to protect people from the diseases that happen to us as we grow old, like Alzheimer’s disease (老年痴呆症),” said senior author, Dena Dubal of University of California.

The KLOTHO gene affects a protein found in the kidneys and the brain that regulates many different body processes. About one in five people carry a single copy of the variant, known as KL-VS, which boosts levels of the protein and is associated with a longer lifespan and improved heart and kidney function. A small minority, 3% of the population, has two copies, which is linked to a shorter lifespan.

In the new study scientists scanned the brains of 422 men and women aged 53 and over who were also tested for the KLOTHO gene. They found that participants with a single copy of the gene variant also had a larger brain region known as RDLPFC, which is especially likely to shrink with age. Loss of neurons in this area may be one reason why older people are sometimes easily distracted and find it difficult to do more than one task at the same time.

Researcher Dr Jennifer Yokoyama said, “The brain region enhanced by genetic variation in KLOTHO is vulnerable (脆弱的) in aging and some mental disease. In this case, bigger size means better function. It will be important to determine whether the structure increase associated with carrying one copy of KL-VS can offset the cognitive shortage caused by disease.”

People who have one copy of a variant KL-VS tend to live longer and have lower chances of suffering a stroke (中风),whereas people who have two copies may live shorter lives and have a higher risk of stroke.

1. What can we learn from the second paragraph?

A．People’s cognitive abilities do not decline if people have KLOTHO.

B．With the clear understanding of KLOTHO, Alzheimer’s disease can be cured now.

C．Genetic variation in KLOTHO could be helpful in treating mental disease in elderly people.

D．Genetic variation in KLOTHO could lead people to suffer from Alzheimer’s disease.

2. If a person carries two copies of the gene variant, he/she may _______.

A．have better kidney funtciton

B．have a shorter lifespan

C．have a higher level of the protein in his/her body

D．suffer from some cognitive disease

3. The reason why older people’s attention is easily distracted may be that _______.

A．they have fewer neurons in the RDLPEC

B．their brain region is too large

C．they have two copies of the gene variant

D．they have more neurons in the RDLPEC

4. What does the underlined word “offset” in Paragraph 5 probably mean?

A．Prevent.

B．Balance.

C．Keep.

D．Promote.
