Easy Ways to Keep Your Brain Sharp

Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing.  1. Read on for some techniques worth trying.

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.

2. Go for a walk

Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain. 4.

3. Learn something new

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time. 5.Or go dancing with your friends.

A. Focus on the future.

B. This can be especially harmful to the aged.

C. It should be something like learning gardening.

D. So take a few minutes each day to do some reading.

E. But don't worry if your schedule isn't filled with life-changing events.

F. Luckily, research shows there is a lot you can do to avoid those moments.

G. In other words, when you take care of your body, you take care of your brain.

If you believe in thermometers（溫度計）,you should believe in global warming. And if you believe in eating fries with your burger, you should worry more about carbon emissions.

It won't happen overnight, but as the planet's climate changes, the growth cycles of main crops will all be heavily affected .Here are three of the crops that might not beat the heat.

The potato actually needs a great deal of beauty rest to develop properly. “They need a cool nighttime temperature in order to start growing the tuber, the part that we eat,” Nelson says.

Temperature and altitude are two primary concerns in coffee growth, and farmers are stuck between a rock and a hard place. “We know that coffee grows in a certain temperature range,” Nelson says. “They've been moving up the mountains, but at some paint you run out of mountains to move up.” Higher-grade strains of Arabica coffee in Central American regions are at particular risk due to the need for lower growing temperature, especially since diseases and pests are also becoming more of a factor as temperatures rise.

Even if you're looking at the direct effects of temperature alone, rice is in trouble. “As nighttime temperatures go up ,the rice is going to have a problem flowering and won't make as many seeds,” Nelson says. In addition to this direct heat consequence, rising sea levels will flood many rice fields and destroy water salinity levels, while droughts will lower production, raise prices, and further shame westerners who are too clumsy with chopsticks to be able to clear their plates once a new grain is adopted.

1.What is the closest meaning to the underlined word “emissions” in Paragraph 1?

A. Mixture. B. Pollution.

C. Going down. D. Letting off.

2.What does the potatoes' development need according to Nelson?

A. Enough water and salt. B. Cool temperature at night.

C. Much sunshine and fresh air. D. Sudden rise of the temperature.

3.The rice is difficult to flower, probably because______.

A. sea levels go up suddenly B. the temperature rises at night

C. many seeds can't be produced D. both temperature and altitude rise

4.What is the best title for the text?

A. How Does Global Warming Affect Westerners

B. How Does The Cool Temperature Affect Ride

C. What Is The Real Reason For Crops' Growth

D. Three Crops That Won't Survive Minor Climate Changes

Andrew Garud,his exercise physiologist（生理學家）,told him,“You are where you are.The pace would be slow; the pain would be real.But as long as you are alive,you have the ability to get better.

After three months of working with Garud,Kraus wanted to see if he could stand.He could.Then he took three steps,sat down and cried like a baby.

科目：高中英語 來源：26省2018屆高三”超級全能生”高考全國卷9月聯(lián)考（乙卷）英語試卷 題型：閱讀理解

Feifei,an 11-year-old boy from Xuzhou,Jiangsu Province,suffered from a sudden acute eye disease which has almost led to blindness.The disease was caused by excessive（過度的）eye fatigue（疲勞）during the winter vacation, during which he played computer games for continuous 10 days and nights.

Many youngsters in China nowadays are increasingly addicted to computer games and other electronic products. This is followed by a series of health problems,with the most typical case being myopia,or nearsightedness.

According to the latest research report released by the World Health Organization (WHO),the myopia rate among Chinese teenagers ranks first in the world—70 percent of high school and college students.The rate is nearly 40 percent in primary school students,while it is only 10 percent for their peers in the United States.

There are at least 10 million people in China with severe myopia,and they are likely to get pathological（病理性的）myopia in middle age.Pathological myopia can't be treated with glasses or surgery,and it is one of the biggest factors that lead to blindness,Xu Xun,director of the ophthalmology（眼科學）department at Shanghai General Hospital,pointed out.

Experts explain that two major factors lead to the high rate of myopia among Chinese people.One is high academic pressure,and the other one is excessive use of electronic devices over a long period of time.Genetics,on the other hand,are not the main reason,as only 20 percent of Chinese people had myopia in the 1960s.

"Teenagers are now faced with severe academic pressure,which means they often study without natural light. This increases their risk of becoming nearsighted,"Xu said.

Experts suggest that youngsters maintain a proper balance between study and rest so as to protect their eyesight, and parents should play an active role in the process.

1.Why does the author mention Feifei's experience in the first paragraph?

A. To advise people to protect their eyes.

B. To introduce the topic of nearsightedness.

C. To inform people of the cause of blindness.

D. To show that Feifei developed an eye disease.

2.What can be learnt from the passage?

A. Nearsightedness may cause other health problems.

B. There are more nearsighted students in the United States.

C. 70 percent Chinese students in primary school are nearsighted.

D. Pathological myopia is most likely to cause blindness.

3.Which of the following can be a main reason for myopia?

A. Genetics factors.

B. Low academic pressure.

C. Overuse of electronic devices.

D. Reading in natural light.

4.What will be probably discussed in the following paragraph?

A. The significance of protecting eyesight.

B. Youngsters’ bad behavior leading to myopia.

C. The relationship between youngsters and their parents.

D. Parents’ role in helping youngsters protect thew eyesight.
