5、rector of linguistics in the English Department at George Mason University in Fairfax, Virginia. He says students in his beginning phonetics class are mostly interested in teaching English as a second language. They wanted to study how non-native speakers pronounce different sounds. So we sent the s
6、tudents out to record non-native speakers, and we compared those speakers to each other and to native speakers of English,” said Steven Weinberger. Professor Weinberger wrote a paragraph for all of the speakers to read. The paragraph uses common words but contains almost all of the sounds used in En
7、glish. Here is that sixty-nine-word paragraph: “Please call Stella. Ask her to bring these things with her from the store: Six spoons of fresh snow peas, five thick slabs of blue cheese, and maybe a snack for her brother Bob. We also need a small plastic snake and a big toy frog for the kids. She ca
8、n scoop these things into three red bags, and we will go meet her Wednesday at the train station.” In 1999, Professor Weinberger put the recordings online. The Speech Accent Archive is for anyone who wants to compare and analyze the accents of different English speakers. Some people think the archiv
9、e would be better if it included natural speech-people talking freely, not just reading the same words. Professor Weinberger recognizes the strengths and weaknesses of his site. Professor Weinberger says the site gets a million visits a month and would like more people to send in theirown samples of
10、 the sixty-nine-word paragraph. Steven Weinberger said, Right now we only have samples from about 350 languages, including English. You know, there are 6, 000 languages in the world today, so we need lots more. Thats why the archive work will never be finished.1.Why did Professor Weinberger let his

Even whe
15、n her daughter and son asked her to move to San Antonio to help their children, she politely refused . Only after a year of friendly discussion did Ms Gaf finally say yes. That was four years ago. Today all three generations regard the move to a success, giving them a closer relationship than they w
16、ould have had in separate cities.No statistics show the number of grandparents like Garza who are moving closer to the children and grandchildren. Yet there is evidence suggesting that the trend is growing. Even President Obamas mother-in-law, Marian Robinson, has agreed to leave Chicago and into th
17、e White House to help care for her granddaughters. According to a study grandparents com. 83 percent of the people said Mrs. Robinson s decision will influence the grandparents in the American family. Two-thirds believe more families will follow the example of Obamas family. “in the 1960s we were al
18、l a little wild and couldnt get away from home far enough fast enough to prove we could do it on our own,” says Christine Crosby, publisher of grate magazine for grandparents .“We now realize how important family is and how important to be near them, especially when youre raining children.” Moving i
19、s not for everyone. Almost every grandparent wants to be with his or her grandchildren and is willing to make sacrifices, but sometimes it is wiser to say no and visit frequently instead. Having your grandchildren far away is hard, especially knowing your adult child is struggling, but giving up the

23、money on time-saving services reduces stress and boosts (增进) happiness, according to a new research, but shockingly, few of us do it. Whillans, a professor at HBS said, “Buying time helps to protect us from the stress in our lives caused by time pressure, and the feeling that we don t have enough mi
24、nutes in the day to complete our tasks. The effect was clearest in the Canadian experiment, in which 60 working adults were given $40 to spend in two different ways. One weekend, they were told to spend the money on a material purchasea gift for themselves. The next weekend, they were instructed to
25、spend the $40 on anything that saved them time, from paying the neighbors kid to run errands (跑腿) to taking a Uber instead of a bus. “On the day they made the time-saving purchase, they felt happier, in a better mood, and lower feelings of time stress than on the day they bought a material purchase”
26、 said Whillans. The biggest surprise to the researchers was how few people would spend money on time-saving services. When they asked 98 working adults how they would spend a “windfall” of $40, only two percent named a purchase that would save them time. “One reason, said Whillans, “is that were ver
27、y bad at remembering how much we hate doing certain tasks once the suffering has passed. That makes us less likely to take active steps to avoid that over burdened feeling in the future.” But another possible cause is good old-fashioned guilt. “If you feel guilty about getting someone to clean your house for you, then you might get less happiness from outsourcing that task,” said Whillans, or you might just be less likely to spend your money in that way. 1.In
