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.

When it comes to making sure our food is safe, we are often advised to wash vegetables and fruits before eating. This has been a good method recommended by food safety experts. However, is this way of cleaning also useful for raw meat? No! The US Departement of Agriculture hs been warning people against washing raw meat before cooking , as it can do more harm than good to our health. Then, why do people want to wash raw meat? Here are some answers.

Some people complain that the unpleasant smell coming from the chicken forces them to wash it.Well, this might never happen if you have bought it from a reliable source. Also, many people say that it helps to get rid of the sliminess(粘連) of the store-bought chicken. And others just want to remove the bacteria from it. But the idea that washing meat helps to clean the chicken is only partly true. This is because some of the bacteria remain firm on the surface, though the meat has been washed several times.

In fact, the surface of the chicken is often polluted with a lot of bacteria. So, when you wash the meat under the tap, it can lead to the bacteria being removed from the meat’s surface, and spreading all over the kitchen. These small infected(受到污染的)water drops can move as far as half a meter. So if you have kept any ready-to-serve dishes on your kitchen top, they are likely to get polluted, and may cause food poisoning if they are eaten.

Of course, if you are really serious about food safety, make sure that the chicken is cooked in a proper way. Eating undercooked meat is another common cause of food poisoning. Bacteria can be killed by the heat of above 70℃. This is the best way to get the bacteria present on raw meat destroyed.

In conclusion, food safety is important but that doesn’t mean that you have to wash raw meat with running water, which carries a lot of health risks.

What would it be like to walk on Mars? If you could build the highest building in the world，what would it look like? Do you dream of being the next J. K. Rowling? This summer, you can experience all of these things, and more. All you need is an Internet connection and your imagination.

A recent study by the Kaiser Family Foundation found that kids spend an average of 1 hour and 29 minutes online each day. Many kids like to use that time to chat with friends, play games or check e?mails. But the next time you get on the Web, try exploring the world instead. “With the Internet，you can go back 11,000 years in time，or go 11,000 kilometers across the planet.” said Russell, Web search expert of Google. “The whole scope of history and the world is open to you.”

There is a wealth of information to be found online. For example, if your family is going on vacation somewhere, do a quick online search on the area before you even get in the car. “What's the background of the place; what's the history？” says Russell. “I like to tell my kids, ‘Whenever you have a question, whenever you have a doubt, search it out.’”

Ready to launch a virtual journey of your own? Here are a few starting points to get you thinking and to help you on your way. You can invite your parents along for the ride, too. Always ask for permission before downloading programs and software onto your computer. And check with a parent or an adult before visiting any new Web site.

Navigate the world in 3?D with Google Earth. Begin in outer space and zoom (快速移動) into the streets of any city, from Hong Kong to San Francisco. Or visit ancient monuments, watch the changing rainforests over time, and dive underwater to explore tropical reef.

With the Moon in Google Earth tool, you can walk in Neil Armstrong's famous footsteps. Take a guided tour of the moon's surface with Armstrong's fellow shuttle mate astronaut Buzz Aldrin.

When you're exploring that part of the solar system, hop on over to the Red Planet with Google Mars. There, you can move very quickly around the surface and see images from the Mars Rovers.

科目：高中英語 來源：2015年廣東茂名高三模擬考試英語試卷（解析版） 題型：閱讀理解

My family moved from Taiwan to a small town in central Georgia，where my dad got a visa for his family and a job． I had just learned English，and from what little I could gather from my classmates，Santa Claus would come down one’s chimney（煙囪） and put toys in one’s stocking on Christmas Eve! What a great country，I thought．After I looked up “stocking” in my Chinese-English dictionary，I knew what I had to do．

On that fateful night，after everyone went to bed，I took my longest，cleanest knee sock and attached it to a nail already on the mantel(壁爐)．Obviously，the previous owners of this house were no strangers to this Santa character．

I woke up before everyone else on Christmas Day and ran to the fireplace．To make a sob story short，I was hit with the reality of an empty sock and the biggest lie ever told． I burst into tears，quickly took down the sock，and stuffed it in the back of a drawer．Santa was dead．

Every December since then，the topic of Christmas memories would unavoidably come up，and I would amuse my friends with my poor-little-me story．I had to make it as funny as possible，or else I would cry．

How could I know that Santa was just late? Nine years ago，on Christmas Eve，an older man with a white beard and a red cap knocked on my front door．He said，“I’ve been looking for you for twenty-five years．” He handed me a bulging red stocking，winked，and left．On top of the stocking was a card． It read: “For Becky—I may have missed you in the second grade，but you’ve always lived in my heart．Santa．”

Through tear-blurred eyes，I recognized the handwriting of Jill，a friend I had met just two months before．I later discovered that the older man was her father．Jill had seen the hurt little girl underneath the thirty-something woman and decided to do something about it．

So now I believe that Santa is real．I don’t mean the twinkle-eyed character of children’s mythology(神話) or the creation of American holiday marketers．Those Santas annoy and sadden me．I believe in the Santa Claus that live inside good and thoughtful people．This Santa does not return to the North Pole after a crazy delivery but lives each day purposefully，really listens to friends，and then plans deliberate acts of kindness．

1.What does the underlined part “what I had to do” in Paragraph 1 refer to?

A． Waiting for Santa Claus．

B． Putting a stocking on the mantel．

C． Asking for gifts from her parents．

D． Looking up “stocking” in the dictionary

2.It can be inferred from the passage that the author’s parents ____．

A． didn’t love their child at all

B． didn’t know the previous owners of the house

C． didn’t know much about Christmas tradition

D． didn’t have enough money to buy the author Christmas presents

3.When the author told her friends about the story，she felt ______in her heart．

A． proud B． amusing C． hate D． regret

4.By writing the passage，the author speaks highly of ________

A． friendship

B． parenting

C． religion

D． culture

5.The author of the passage is probably ________．

A． a teenager

B． a primary school student

C． a middle-aged woman

D． a native American
