Jack Ma's net worth increased $2.8bn overnight as Alibaba forecast sales growth that topped every analyst's estimate, despite the fact that China's economy is slowing down.

    Mr. Ma, aged 52 this year, is now the richest person in Asia and 14^th wealthiest in the world, according to the Bloomberg Billionaires Index. His net worth has climbed $8.5bn this year to $（4）8bn.

    The latest surge came after China's largest e-commerce company forecast 45 to 49 percent revenue(收入) growth in the year ending March, demonstrating how investments beyond online shopping are paying off. Shares in Alibaba, where Mr. Ma is chairman, rose 13 percent to a record high.

    Alibaba and Tencent, which dominate online shopping and social media, respectively have ventured(冒险) deeper into new areas from cloud computing services to streaming music and video as the country's economy slows. Alibaba is capturing more digital advertising spending by incorporating(合并) social elements such as video in its shopping sites.

    Alibaba is holding meetings with investors this week. On Friday, the former English teacher said he wasn't going to discuss corporate forecasts. He took the stage instead to describe how his company had become effectively the world's 22^nd largest economy—just after Argentina—in terms of transaction(交易) by never fearing to think big. Mr. Ma, who said Alibaba revises 10-year plans annually, foresaw the company becoming the fifth-largest eventually by 2036 by serving a burgeoning Chinese middle classes, taking advantage of global trade and making use of its valuable data.

    Ma's comments about the evolution of data-driven technology echoed Masayoshi Son, Chairman of Japan's SoftBank. SoftBank—Alibaba's largest shareholder—has invested billions in companies such as ARM with the intention of staking out a leading position in the future Internet of Things.

    “The Internet of Things is going to be big because in the past, machines drink electricity,” Mr. Ma told investors. “In the next 20 years, machines will drink data. In the future, no company, no country, no business can survive without data.”

请回答：

People on a college campus were more likely to give money to the March of Dimes if they were asked for a donation by a disabled woman in a wheelchair than if asked by a nondisabled woman. In another 1 , subway riders in New York saw a man carrying a stick stumble（绊脚） and fall to the floor. Sometimes the victim had a large red birthmark on his2; sometimes he did not. In this situation, the victim was more likely to 3 aid if his face was spotless than if he had an unattractive birthmark. In 4 these and other research findings, two themes are 5 : we are more willing to help people we like for some reason and people we think6assistance.

In some situations, those who are physically attractive are more likely to receive aid. 7 , in a field study researchers placed a completed application to graduate school in a telephone box at the airport. The application was ready to be 8 , but had apparently been "lost". The photo attached to the application was sometimes that of a very 9 person and sometimes that of a less attractive person. The measure of helping was whether the individual who found the envelope actually mailed it or not. Results showed that people were more likely to 10 the application if the person in the photo was physically attractive.

The degree of 11 between the potential helper and the person in need is also important. For example, people are more likely to help a stranger who is from the same country rather than a foreigner. In one study, shoppers on a busy street in Scotland were more likely to help a person wearing a(n) 12 T-shirt than a person wearing a T-shirt printed with offensive words.

Whether a person receives help depends in part on the "worth" of the case. For example, shoppers in a supermarket were more likely to give someone. 13 to buy milk rather than to buy cookies, probably because milk is thought more essential for 14 than cookies. Passengers on a New York subway were more likely to help a man who fell to the ground if he appeared to be 15 rather than drunk.
