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 (早老性痴呆症), 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.
On a stormy day last August, Tim heard some shouting. Looking out to the sea carefully, he saw a couple of kids in a rowboat were being pulled out to sea.
Two 12-year-old boys, Christian and Jack, rowed out a boat to search for a football. Once they'd rowed beyond the calm waters, a beach umbrella tied to the boat caught the wind and pulled the boat into open water. The pair panicked and tried to row back to shore. But they were no match for it and the boat was out of control.
Tim knew it would soon be swallowed by the waves.
"Everything went quiet in my head," Tim recalls(回忆). "I was trying to figure out how to swim to the boys in a straight line."
Tim took off his clothes and jumped into the water. Every 500 yards or so, he raised his head to judge his progress. "At one point, I considered turning back," he says. "I wondered if I was putting my life at risk." After 30 minutes of struggling, he was close enough to yell to the boys, "Take down the umbrella!"
Christian made much effort to take down the umbrella. Then Tim was able to catch up and climb aboard the boat. He took over rowing, but the waves were almost too strong for him.
"Let's aim for the pier(码头)," Jack said. Tim turned the boat toward it. Soon afterward, waves crashed over the boat, and it began to sink. "Can you guys swim?" he cried. "A little bit," the boys said.
Once they were in the water, Tim decided it would be safer and faster for him to pull the boys toward the pier. Christian and Jack were wearing life jackets and floated on their backs. Tim swan toward land as water washed over the boys' faces.
“Are we almost there?" they asked again and again. "Yes," Tim told them each time.
After 30minutes, they reached the pier.
1.Why did the two boys go to the sea?
A. To go boat rowing.
B. To get back their football.
C. To swim in the open water.
D. To test the umbrella as a sail.
2. What does “it” in Paragraph 2 refer to?
A. The beach. B. The water.
C. The wind. D. The boat.
3.How can the two boys finally reach the pier?
A. They swam to the pier all by themselves.
B. They were dragged to the pier by Tim.
C. They were washed to the pier by the waves.
D. They were carried to the pier by Tim on his back.
The morning had been a disaster. My tooth was aching, and I’d been in an argument with a friend. Her words still hurt: “The trouble with you is that you won’t put yourself in my place. Can’t you see things from my point of view?” I shook my head stubbornly—and felt the ache in my tooth. I’d thought I could hold out till my dentist came back from holiday, but the pain was really unbearable. I started calling the dentists in the phone book, but no one could see me immediately. Finally, at about lunchtime, I got lucky.
“If you come by right now,” the receptionist said, “the dentist will fit you in.”
I took my purse and keys and rushed to my car. But suddenly I began to doubt about the dentist. What kind of dentist would be so eager to treat someone at such short time? Why wasn’t he as busy as the others?
In the dentist’s office, I sat down and looked around. I saw nothing but the bare walls and I became even more worried. The assistant noticed my nervousness and placed her warm hand over my ice-cold one.
When I told her my fears, she laughed and said, “Don’t worry. The dentist is very good.”
“How long do I have to wait for him?” I asked impatiently.
“Come on, he is coming. Just lie down and relax. And enjoy the artwork,” the assistant said.
“The artwork?” I was puzzled.
The chair went back, suddenly I smiled. There was a beautiful picture, right where I could enjoy it: on the ceiling. How considerate the dentist was! At that moment, I began to understand what my friend meant by her words.
What a relief！

Bicycle Safety

Theft Prevention Always securely lock your bicycle to a bicycle rack — even if you are only away for a minute. Register your bike with the University Department of Public Safety. It's fast, easy, and free. Registration permanently records your serial number, which is useful in the possible recovery of the bike stolen.
Equipment
Brakes Make sure that they are in good working order and adjusted properly.
Helmet A necessity, make sure your helmet meets current safety standards and fits properly.
Lights Always have a front headlight — visible at least 500 feet in front of the bike. A taillight is a good idea.

Passage 1
The Information Highway is the road that links computer users to a large number of on-line services: the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowded road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.
Passage 2
