Ten-year-old Lena Draper decided to reach out...

Ten-year-old Lena Draper decided to reach out to the Marion Police Department on Facebook after getting stuck on the maths questions. Instead of ignoring her request, Ohio officer Lieutenant B. J. Gruber did his best to lend a hand.

Lena informed the policeman that she was stuck on the problem(8+29)×15. He quickly responded: ”Do the numbers in the parentheses(括号) first so in fact it would be 37×15.”

After settling the first question, Lieutenant Gruber was given a more difficult task. Lena asked him for the answer to (90+27)+(29+15)×2. The confident officer responded with what he believed to be the correct answer, advising: ”Take the answer from the first parentheses plus the answer from the second parentheses and multiply that answer by two. Work left to right doing the work in parentheses first.”

But embarrassingly, Facebook users were quick to notice that his maths solving didn’t quite add up. To solve the problem, you must actually add the numbers in the second parentheses and multiply the answer by two, before adding the numbers in the first set of brackets.

Lena’s mum Molly said, ”I didn’t believe her at first. I thought it was pretty funny. I was happy, but not surprised that they responded so quickly. They are wonderful with their communication with the community.”

After Lieutenant Gruber was told about the mistake, he joked: “Hoping it is truly the thought that counts since obviously I can’t! Especially since the answer was wrong, it was very nice for Molly to recognize our attempt to help her daughter with some maths homework.”

It’s not the first time that adults have been left feeling trapped by a maths assignment aimed at kids.

Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?

To see whether babies know objects are solid. T. Bower designed a method for projecting an optical illusion (视觉影像) of a hanging ball. His plan was to first give babies a real ball, one they could be expected to show surprise in their faces and movements. All the 16 to 24-week-old babies tested were surprised when they reached for the illusion and found that the ball was not there.

Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land (想像中的地方)?

Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to re-appear. If the experiment took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted (替换) a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week-old babies did not seem to notice the switch (更换). Thus, the 16-week-old babies seemed to have a sense of “something permanence,” while the 22-week-old babies had a sense of object permanence related to a particular object.

1.The passage is mainly about ______.

2.. In Paragraph 3, “object permanence” means that when out of sight, “object ______”.

3.. What did Bower use in his experiments?

4. Which of the following statements is true?

You’re out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why? The answer may not be as simple as you think.

Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words to how they carry themselves while taking orders to the bill’s total.

“Studies before have shown that mimicry (模仿) brings into positive feelings for the mimicker,” wrote Rick van Baaren, a social psychology professor. “These studies show that people who are being mimicked become more generous toward the person who mimics them.”

So Rick van Baren divided 59 waiters into two groups. He requested that half serve with a phrase such as, “Coming up!” Those in the other half were instructed to repeat the orders and preferences back to the customers. Rick van Baaren then compared their take-home(实得收入). The results were clear---it pays to mimic your customer. The copycat waiters earned almost double the amount of tips to the other group.

Leonard Green and Joel Myerson, psychologists at Washington University in St. Louis, found the generosity of a tipper may be limited by his bill. After research on the 1,000 tips left for waiters, cab drivers, hair stylists, they found tip percentages in these three areas dropped as customers’ bills went up.

“That’s also a point of tipping,” Green says. “You have to give a little extra to the cab driver for being there to pick you up and something to the waiter for being there to serve you. If they weren’t there you’d never get any service. So part of the idea of a tip is for just being there.”

1.According to the passage, a customer gives the cab driver a tip for ____.

A. driver’s politeness   B. being there    C. driver’s attitudes   D. driver’s mimicry

2.According to the passage, which of the following will be likely to show the right change of the tip percentages for the three areas researched?

3.According to the passage, we know the writer seems to _________.

A. oppose Mr. Green’s idea about tipping

B. support the opinions of Mr. Green and Rick van Baaren about tipping

C. give his generous tip to the waiters very often

D. think part of Mr. Green’s explanation is reasonable
