"Welcome to the U. S. A.! Major Credit cards accepted!"
By the millions they are coming no longer the tired, the poor, the wretched mass longing for a better living. These are the wealthy. "We don't have a budget," says a biologist from Brazil, as she walks with two companions through New York City's South Street. "We just use our credit cards."
The U. S. has long been one of the world's most popular tourist destinations, but this year has been exceptional. First there was the World Cup, which drew thousands from every comer of the globe; then came the weakening of the U. S. dollar against major currencies. Now the U. S. still the world's superpower, can also claim to be the world's bargain electronics to fashion clothes to tennis rackets. Nobody undersells America Bottom retail prices --anywhere from 30% to 70% lower than those in Europe and Asia-have attracted some 47 million visitors, who are expected to leave behind $79 billion in 1994.
That's up from $74 billion the year before.
True, not everyone comes just for bargains. There remains an undeniable fascination in the rest of the world with all things American, nourished by Hollywood films and U. S. television series. But shopping in the U. S. A. is proving irresistible. Every week thousands arrive with empty suitcases ready to be filled; some even rent an additional hotel room to hold their purchases. The buying binge has become as important as watching Old Faithful Fountains erupt in Yellow Stone Park or sunbathing on a beach in Florida.
The U. S. has come at last to appreciate what other countries learned long ago: the pouring in of foreign tourists may not always be convenient, but it does put money in the bank. And with a trade deficit at about $130 billion and growing for the past 12 months, the U. S. needs all the deposits it can get. Compared with American tourists abroad, visitors to the U. S. stay longer and spend more money at each stop; an average of 12. 2 nights and $1624 a traveler versus the Americans' four nights and $298.
The vast majority of us spend our entire lives pulled down by gravity. Then there are astronauts.
This small population of space travelers has given researchers a rare look at what happens to the human body when it's able to spend large amounts of time outside the downward pull of the Earth. This week, a study on one of the largest groups of astronauts yet —34 participants—was published in The New England Journal of Medicine.
In the new study, a team of international radiologists supported by NASA looked at MRIs of the brains of astronauts before and after their trips to space. The scientists found that upon returning to Earth, many of the astronauts' brains had become repositioned inside their skulls, floating higher than before. In addition, the space between certain brain areas appeared to have shrunk. The changes were more common in astronauts who took longer trips into space.
The team characterized astronaut trips as short (an average of less than 14 days) or long (an average of about 165 days). Radiologists who didn't know each astronaut's duration(持续时间)in space compared MRIs from before and after their trips.
Of the 34 total astronauts involved in the study, 18 took long trips to space—spending most of that time on the International Space Station —and of those, 17 returned to Earth with smaller areas between the frontal lobe(脑前额叶)and parietal lobe(顶叶). The same area of the brain also shrank for three of the 16 astronauts who took shorter trips with the US Space Shuttle Program. The researchers also found that 12 of the ISS astronauts and six of the space-shuttle astronauts returned home with their brains sitting slightly higher in their skulls than before.
It's not clear what, if anything, these brain changes mean for the health of space travelers. In general, it appears the human body tolerates space travel fairly well: the time astronauts have spent in zero-gravity environments so far doesn't seem to have had any strong or long-lasting effects.

Last Monday, we hold a monitor election during our class meeting. Two students in our class took part the event. They are Liu Dong and Wang Hong, all of whom are the top students in our grade. Before the election, they each gave a briefly presentation about their plan after become the monitor. At the last, the winner turned out to be Wang Hong, who gained 28 votes when Liu Dong gained 15. Obviously, we thought Wang Hong's plan a good one. In the end, we gave Wang Hong a big hand but congratulated her. I expect that our class will be better under his leadership.

The Chinese traditional festival I like best
There are many traditional festivals in China.
Currently offered by some famous universities, MOOCs are attractive to people who do not have the financial resources to meet the growing costs of university education, or who do not have formal qualifications. They also allow participants to study at their own pace.
The potential for MOOCs to deliver education is obviously vast—they could be considered as a huge step forwards in widening participation. They also have the potential to provide a unique window on universities that offer popular and valuable courses, they may attract some participants to register for formal fee-paying programmes at the same or other universities and are likely to promote new ways of on-line education.
However, it is still very early days for MOOCs. The quality of the education provision is highly variable, with many courses offering only recordings of lectures, and delivery is particularly difficult in some special fields that require practical classes, research projects or extensive library access. Besides, wider engagement with participants requires very considerable resource. Even limited feedback or examination becomes a major task if there are several thousand students in the class.
Considering the challenges, some people argue MOOCs will soon evaporate (蒸发). But they certainly provide good opportunity for widening higher education, are a means of raising awareness of universities to audiences of tens or hundreds of thousands, and are well worthy of serious consideration.

Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually bemore than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.
I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost allof them felt angry towards pedestrians who crossed streets carelessly. The joke wasn't only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because ofthe funny joke and because of the happiness experienced as a result of the psychological support they got.
The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh atit louder than if you weren't jealous of him.
In short, we don't laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All Iwant to explain is that if your joke supports a person's emotions, he will certainly like it a lot.
B . China, which takes pride in inventions in ancient times, has once again demonstrated its (able) to change the world with its “new four great inventions”: high-speed railways, electronic payments, (share) bicycles and online shopping. The “new four great inventions” are all related China's high-tech innovation(创新), which has improved the quality of people's lives. “My wallet is no longer in use. I can buy and eat anything I want simply with a tap of my phone,” said Lin Jinlong,overseas Chinese student from Cambodia, (add) that “even pancake sellers are using Alipay (mobile payment). We can also order food at home, which is super convenient. If I (be) at home in Cambodia, I would have to go outdoors.”
The bikes themselves are not new, but the operating model of bike-sharing is based on satellite navigation system, mobile payment, big data and other high technologies. It is (increase) clear that China is innovating and no longer copying Western ideas. This is partly because China skipped over the PC age and went directly to mobile. China has the (large) mobile use in the world.
In terms of the “new four great inventions”, Charlie Dai, principal analyst of American market research company Forrester, said, “These products and services (improve) the customer experience so far, improving national and global economy at the same time”.
