You are sitting on the desk. A teacher is writing on the blackboard. Kids are yelling in the playground outside. A book falls off the desk next to you. Suddenly, the teacher hands you a pop quiz.

Don’t panic! 1. You’re in a “virtual（虛擬的）classroom”. Everything you see and hear is coming to you through a computer-operated display that you’re wearing on your head like a pair of very big glasses. Wearing this kind of virtual-reality equipment, you can find yourself sitting in a classroom, touring a famous museum, wandering across a strange landscape, flying into space, or playing with a cartoon character. 2. Virtual-reality equipment that delivers images and sounds directly to your eyes and ears makes these fake worlds seem lifelike.

Unlike the classroom, the technology is real. It’s a type of technology that uses computer programs to imitate real world situation. 3. Movie directors and video game producers have been using computers for years to create ever more realistic special effects. Some companies are now building three-dimensional（三維）fantasy worlds in which players, linked by computer networks, appear to meet and go on explorations together.

4. They see virtual reality technology as a useful tool for learning more about why people act as they do. It could help psychologists deter identify and come up with solutions for behaviors problems, for example.

“We’ve spent the last 100 years looking for certain laws in how people interact with the real world,” says psychologist Albert. “ 5. This is psychologist’s dream.”

A. You aren’t actually in school.

B. This technology has been used in many fields.

C. Some psychologists are also getting into the act.

D. Grown-ups, too, stand a chance of benefiting from this technology.

E. As part of one classic test, you watch letters flashed on a computer screen.

F. You don’t have to leave your room to experience all that mentioned above.

G. Now, we’ve got a powerful tool that lets us create worlds and see how people perform.

The weather is getting hotter and you’ll be getting thirstier playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you pour down your throat. Something that looks cool may not be good for your health.

There are plenty of so-called energy drinks on the market. Most of them have an attractive colour and cool name. Their nutrition list also contains various things from vitamins to ginseng. Sounds great!

Caffeine raises your heartbeat. Because of this, the International Olympic Committee has limited their use. The amount of caffeine in most energy drinks is at least as high as in a strong cup of coffee or strong tea.

The First Rule of Finance is to live within your means by spending no more than 80% of your take-home pay．If you take home $ 100 per week, spend no more than $80．

But ever look at what people spend their money on? I have relatives and friends deeply in debt, spending $ 12 for every $ 10 they earn instead of the $ 8 you know they should be spending．When I see them, they're proud of their new whatever．"What do you think of my new truck?" asked one from the driver's seat．"Do you like my new shoes?" asked another on high heels．"Check out my new big screen．" said a third while holding the remote in his living room．We've all heard people fishing for compliments on their new toys．

Every one of them was proud of what they'd financed．They seem to have bought it for the purpose of being proud, of showing off, of keeping up with the Joneses．"Look at my new …?"is everybody's favorite phrase, even when the object in question isn't theirs at all and won't be new when they've finally paid for it, if they ever do．

They're proud of being stupid．They think it's cool to drive the financed car, wear the financed shoes, and watch the financed TV, but to smart people, whose opinions are the only ones we should respect, these people look dumb as rocks．

The Joneses, nine times out of 10, are financially stupid．That's why they have all that stuff on borrowed money．Why try to copy them? Worse, why try to impress them? Copy and impress smart people, the ones who own their stuff．If you want to impress smart people, debt is the last way to go about it．Trying to impress a money-smart person by going into debt is like trying to impress Olympic swimming champion Michael Phelps by drowning in a pool．Michael Phelps is impressed by good swimming and a money-smart person by good money management．

1.According to the author, the "new toys" in Paragraph 2 are examples of______.

A. symbol of wealth B. unnecessary purchases

C. impressive stuff D. things available

2.The underlined words "smart people" in Paragraph 4 refer to people ______.

A. having high IQs B. earning enough money

科目：高中英語 來源：湖北省武漢市武昌區(qū)2017屆高三5月調(diào)研考試英語試卷 題型：閱讀理解

Nothing succeeds like success, as every parent of a straight-A student knows, but trying to highlight academic excellence by telling your child, "You're so smart," may be counterproductive（負效的）. Telling kids they're smart strengthens the idea that intelligence is a genetic gift rather than a skill that can be developed.

In a recent study, researchers at Michigan State University looked at 123 children who were about 7. The team assessed the children to determine whether they had a "growth mindset（思維模式）" (believing that you can work harder to get smarter), or a "fixed mindset"(believing that your intelligence is unable to change). They then asked the children to complete a fast-paced computer accuracy task while their brain activity was recorded. In the task, children played a game, helping a zookeeper capture escaped animals by pressing the space bar when an animal showed up in their screen—unless it was a group of three chimps. During the recording, researchers noted that brain activity spiked within a half-second after making a mistake, as children became aware of their error and paid closer attention to what went wrong. The larger the brain response, the more the children focused on the error.

Based on the data they collected, the researchers concluded that children with a "growth mindset" were much more likely to have a larger brain response after making a mistake, and in turn were more likely to improve their performance by paying closer attention to the task after making an error.

For parents, the lessons are clear: don't pay compliments(贊揚) that suggest that intelligence is fixed. If a child hands you an A+ test, don't say, "You're so smart!" Instead say, "Wow, that studying really paid off!" Note the effort, not the intelligence. Second, focus on using errors to work together and learn. "Many parents and teachers shy away from addressing a child's mistakes, telling them "It's OK. You'll get it next time." without giving them the opportunity to figure out what went wrong." Dr. Schroder says. Here are additional ways you can help enhance your child's education.

1.What can learn about children's mindset from the study?

A. Children are born with a fixed or growth mindset.

B. Children with a fixed mindset pay no attention to mistakes.

C. Children with a growth mindset are more likely to make progress.

D. Children with a growth mindset can catch more animals in the game.

2.Which of the following has the closest meaning with the underlined word in Paragraph 2?

A. started B. stopped

C. paused D. rose

3.What should parents say to children's performance according to the passage?

A. "You are so clever!" for excellence.

B. "It's not good enough." for excellence.

C. "You can benefit from it." for a mistake.

D. "It's OK. Forget about it." for a mistake.

4.What would be the best title for the passage?

A. Never Call Your Kid Smart

B. Always Be Strict with Your Kid

C. How to Communicate with Your Kid

D. How to Comment on Your Kid's Performance
