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.

Last Friday we have a discussion about whether it is the only way out for senior students to go to college. Views vary from person to person.

The majority of us consider this very necessary to go to college. They think it can be widen their knowledge and improve their qualities. Only in this way can they find better jobs before graduation. Very few students think it no use go to university, because the tuition is too high for their family to afford. What’s more, it’s rather hard for college graduates to seek satisfied jobs. Thirty percents of the students, however, believe “All roads lead Rome.” Therefore, it doesn’t make some difference whether they go to college or not.

In my opinion, we can better themselves through college education so that we can serve society better in the future.

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.

A great loss—Shirley Temple dies at 85

February 12，2014

BY DERRIK J．LANG，Associated Press

Shirley Temple Black，who died on February 10th at age 85，wasn’t just a child star．She was THE child star—the sweet little girl whose shining smile helped illumine some of the darkest days the US has known during the Great Depression．

It’s hard today to imagine the super star Shirley was once “America’s Little Darling”．She sang and danced her way to the top of the box office in such films as Bright Eyes，Curly Top and Heidi．By 1940，she had appeared in 43 films．Temple teamed with Bill Robison in four movies，and their dance on the stairs in The Little Colonel is still a legendary film moment．

In the 1930s，her name on a movie introduction assured（保證）a packed house．She inspired dolls，dresses，dishes—even a drink（alcohol-free，of course）．

US President Franklind． Roosevelt once famously said that “as long as our country has Shirley Temple，we will be all right．”

Unlike so many of today’s child stars，Temple didn’t end up with her name appearing across the headlines for bad behaviors．Instead of getting her photos on front pages or struggling with drugs and alcohol，Temple went on to a second career in diplomacy（外交），including presidential appointments as ambassador to Ghana．

She surprised a lot of people who doubted her with her grace，knowledge and eagerness to serve．In fact，her career in public service（20 years）was longer than her career in movies（19）．The role she valued most，however，was as wife，mother，grandmother and great-grandmother．

The world has lost a treasured Hollywood legend． But her movies will allow that little dynamic figure to continue charming audiences for a very long time．

1.The word “illumine” in Paragraph 1 means _______．

A． shorten B． sweeten

C． strengthen D． brighten

2.Temple，as a child movie star，can best be described as _______．

A． sweet and lively

B． gentle and kind

C． smart and knowledgeable

D． shy and attractive

3.What part did she regard as the most important in her life？

A． A top movie star．

B． A businesswoman．

C． Her family role．

D． Her diplomacy career．

4.Where does this passage possibly come from？

A． A biography B． A newspaper

C． A magazine D． A poster
