If you’re looking to buy a gift for your children, why not keep up with the trend and get the best hoverboard?
What is a Hoverboard?
A hoverboard is a two-wheeled personal transportation device. It’s electrical, portable and became highly popular in 2015 in reference to a popular 1980’s movie. Typically, this self-balancing device operates like a powered skateboard.
How Does a Hoverboard Work?
The device may have many designs, but the mechanism itself isn’t complicated. Basically, a standard hoverboard contains:
•Battery: stores the electrical power. Almost all hoverboards use a high-watt lithium-ion battery.
•Gyroscope (one for each wheel): allows riders to tilt (倾斜) the hoverboard while maintaining balance and adjusting their direction.
•Motor (one in each wheel): provides the power to the wheels to keep the rider balanced and upright.
•Logic board: functions as the hoverboard brain. It processes data — your speed, tilt, etc. — and sends information to the motors. This unit controls the power of the board so riders can adjust their speed.
All the above components work together to control the power and tilt of the hoverboards so the rider is balanced, upright and moving at a controlled speed.
Why Buy a Hoverboard?
Undoubtedly, hoverboards are cool. You’ve probably seen kids riding one around the house. They’re a phenomenon and everybody wants in. So, why deny your kids and prevent them from being part of this trend?
Where is a hoverboard legal?
Despite their wild popularity, hoverboards have yet to become “street-legal”. Currently, some places prohibit anyone under 16 from using these devices, and hoverboards are banned in academic institutions and public places, like campus buildings, parks, shopping malls and subway stations. Some places have also put speed limits on the devices and restricted their use to bike paths. However, open areas — including your yard — are free of these restrictions.
1.The logic board of a hoverboard can ______.
A.store electricity
B.power the wheels
C.send information to the riders
D.receive data and give command
2.According to the passage, a hoverboard can be used ______.
A.on campus B.in parks
C.on bike paths D.in shopping malls
3.What is the main purpose of this passage?
A.To evaluate a gift’s quality.
B.To recommend a gift choice.
C.To compare new hoverboard models.
D.To clarify functions of the latest hoverboards.

You are careful with your money: you collect all kinds of coupons; look for group-buy deals if you eat out; you don't buy clothes unless in a sale. Does all this make you a wise consumer?
Let's do the math first: you walk into a coffee shop and see two deals for a cup of coffee. The first deal offers 33 percent extra coffee. The second takes 33 percent off the regular price. What's the better deal? Well, they are about the same, you'd think. And you'd be wrong. The deals appear to be equal, but in fact, they are different. Here's the math: Let's say the standard coffee is 10 yuan and let's divide the amount of coffee into three portions(部分). That makes about 3.3 yuan per portion, The first deal gets you 4 portions for 10 yuan (2.5 yuan per portion) and the second gets you 3 portions of coffee for 6.6 yuan (2.2 yuan per portion) and is therefore a better deal.
In a new study published by the Journal of Marketing, participants were asked the same question, and most of them chose the first deal, the Atlantic website reported. Why? Because getting something extra for free feels better than getting the same for less. The applications of this view into consumer psychology(心理) are huge. Instead of offering direct discounts, shops offer larger sizes or free samples.
According to the study, the reason why these marketing tricks work is that consumers don't really know how much anything should cost, so we rely on parts of our brains that aren't strictly quantitative.
There are some traps we should be aware of when shopping. First of all, we are heavily influenced by the first number. Suppose you are shopping in Hong Kong. You walk into Hermes, and you see a 100,000 yuan bag. "That's crazy." You shake your head and leave. The next shop is Gucci, a handbag here costs 25,000 yuan. The price is still high, but compared to the 100,000 yuan price tag you just committed to your memory, this is a steal. Stores often use the price difference to set consumers' expectation.
Another trap we often fall to Is that we are not really sure what things are worth. And so we use clues(暗示) to tell us what we ought to pay for them. US economist Dan Ariely has done an experiment to prove this. According to the Atlantic, Ariely pretended he was giving a lecture on poetry. He told one group of students that the tickets cost money and another group that they would be paid to attend. Then he informed both groups that thelecture was free. The first group was anxious to attend, believing they were getting something of value for free. The second group mostly declined, believing they were being forced to volunteer for the same event without reward.
What's a lecture on poetry by an economist worth? The students had no idea. That's the point. Do we really know what a shirt is worth ? What about a cup of coffee? What's the worth of a life insurance.policy? Who knows? Most of us don't. As a result, our shopping brain uses only what is knowable: visual(祝觉的) clues, invited emotions, comparisons, and a sense of bargain. We are not stupid. We are just easily influenced.
1.The first paragraph of the passage is intended to________
A.ask a question B.introduce a topic
C.give some examples D.describe a phenomenon
2.The writer takes the math for example in Paragraph 2 to show. _.
A.consumers usually fall into marketing traps
B.consumers' expectation is difficult to predict
C.consumers' purchasing power is always changing
D.consumers rely on their own judgment when shopping
3.What consumer psychology is mentioned in the passage?
A.The first number has little influence on which item should be bought.
B.Consumers never use visual clues to decide how much should be paid.
C.Getting something extra for free is better than getting the same for less.
D.Consumers never rely on parts of the brains that aren't strictly quantitative.
4.According to the passage, shops use the following tricks to make more profits EXCEPT.
A.showing price differences B.offering larger sizes
C.providing free samples D.giving direct discounts
5.What can we know from US economist Dan Ariely's experiment?
A.Ariely's free lecture enjoyed popularity among students.
B.The students actually didn't know what the lecture was worth.
C.The second group was willing to be volunteers without reward.
D.The first group was eager to find out the value of Ariely's lecture.

Why you shouldn’t punish your kids for lying
Getting your children to stop lying is challenging. There are many influences (TV, movies, video games and some great books) in which lies are common. Children see parents lie to others, if only to be polite. Most parents add to that with tales about the lives and activities of Santa Claus or the Tooth Fairy, or to lessen fears. 1.
The most common reactions to children who lie are explaining why it is wrong and punishment. 2. Here are three better tools supported by research to use instead.
PRAISE: You could ask your child to say something that happened at school that is true. When your child obeys, praise him enthusiastically. Be specific: 3. and give your child a hug or a high five. Aim for one or two interactions (互动) like this a day. If you happen to “catch” your child in a lie, say something like, “That is not true and could get you in trouble outside of the home.”
MODEL: Explicitly tell the truth. This could be about something that happened when you were a child or something that happened during the day. It need not be dramatic. Another option is to play a game at dinner. Each person tells one thing that was true that day. Again, give a little praise to the child who normally lies if she plays along.
DECREASE PUNISHMENT AND MORALIZING: They are unlikely to change behavior or develop the conduct you want.4. Rather, use very mild punishment (light scolding, short loss of privilege, a brief time-out). More severe punishments (shouting, taking away something for a week, hitting) are not more effective in actually changing the frequency of lying.
5. Usually they can be dropped by then. It is unlikely that lying will be completely removed, but with the right encouragement, k can be dramatically lessened.
A. It is not what that is, but about practice.
B. As ways of changing behavior, these are ineffective.
C. That does not mean ignoring, lying or letting it go.
D. “That was great! You told me what happened just like I asked. Wow!”
E. Try these procedures for two to three weeks and see where you are.
F. “You did a good job, but what you said was not what I’d like to know!”
G. Parents do this out of love, but for some children, lying can become a problem.
