Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which form different cultures. One important particular side of every culture is how its people deal with time. Time is not very important in nonindustrial societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such nonindustrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar ,but by saying that an event takes place before or after some other event . Frequently such a society measures day in terms of"sleeps"of longer periods in terms of"moons".Some cultures, such as the Eakinos of Greenland measure seasons according to the migration of certain animals. Some cultures which do not have a written language or keep written records have developed interesting ways of"telling time".For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed-upon time has arrived and the event can take place. In contrast ,exactly correct measurement of time is very important in modern, industrialized societies. This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently(well, quickly and without waste),for example, all of the workers must work at the same time. YCTherefore, they must know what time to start... By saying"Humans are social animals", the author means_. A) they live all over the world B) they are different from other animals C) they live in one place, district or country, considered as a whole D) they are divided into many groups

Reseachers at the University of Kansas say that people can accurately juage 90 percent of a stranger's personality simply by looking at the person's shoes."Shoes convey useful information about their wearers,''the authors wrote in the new study published in the Journal of Research in Personality. Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone's shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study's participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire. Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,"practical and functional'' shoes were generally worn by more "pleasant" people,while ankle boots were more linked with ''aggressive'' personalities.The strangest of all may be that those who wore' 'uncomfortable looking" shoes tend to have "calm" personalities.And if you have several pairs of new shoes or take extreme care of them,you may suffer from "attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal types wearing "shabbier and less expensive" shoes. The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities. The participants were asked to A) provide pictures of their shoes B) look at pictures of different shoes C) design a personality questionnaire D) hand in their commonly worn shoes

Q: Hong Kong, a city of seven million--and growing fast. By the year 2050 Hong Kong's population will almost double. Where will these people live? There's only one place to go--up. Fast forward 50 years.This is the tallest man-made structure on the planet. Its name:Millennium Tower. It would stand twice as tall as anything built before. Over 60 thousand people would live or work here. Millennium's designers think it represents the best solution for the coming population explosion. It would cost ten billion dollars and consume more building materials than any single nation could produce. David Nelson, one of Millennium's key designers, said:"It would be a massive project and a world project. But to actually realize it, resources would have to come from all over the globe. The challenge and the motivation for doing it would be to realize one of the world's largest and most complex construction projects." Millennium would be more complex than anything ever built. So its builders won't know for sure the building is safe until it's up, and they can't afford to make an error. Massive earthquakes have brought down entire cities in this part of the world. Can Millennium's designers make it immune to these quakes of the earth? For Millennium, like all the other buildings, safety is just one concern among many. It will need to be a home, one that welcomes people in. Getting people into the building and making sure they have a great experience well be what makes Millennium successful, but how to do it? For the design team, the secret was to bring all the elements of city life within. Cafes and restaurants, theatres and stores would provide entertainment. Health clubs, even schools and medical clinics would also serve the towers' residents. Millennium's designers have proven something. Things that seem impossible today, might just become reality tomorrow. The engineering problems have, for the most part, already been solved. Our achievements are limited only by our imaginations. What is TRUE about the project? A) It will be completed in the year 2050. B) It can accommodate all the residents in Hong Kong. C) It is designed by designers from all over the globe. D) It has to be strong enough to stand earthquakes.
A: D
*Question*
Showering typically sends water down the drain, but a new space-age shower could change that. The design, inspired by NASA, saves water and money. Astronauts have no choice but to recycle the water they use in space. _ This futuristic shower comes from Orbital Systems, a Swedish advanced technology company. Its CEO, Mehrdad Mahdjoubi, invented the product. "The shower of the future is a water-recycling shower, thus enabling water savings up to 90 percent, energy savings up to 80 percent, at the same time increasing comfort and hygiene. The water is being collected in the drain, it's being analyzed, purified and then pumped back up to the shower head. So what is so special about the purification technology? Well, it's based on a patented purification capsule system that makes sure that the water is always crystal clear," he explained. Mahdjoubi was inspired by a project between NASA and Sweden's Lund University to come up with designs for a mission to Mars. He adapted the closed-loop system that allows astronauts to re-use shower water again and again. The product already has been tested in Sweden, where it saved up to 100,000 liters of water over four months. Based on those results, Mahdjoubi is confident his company can distribute the shower system worldwide. "Our market is anyone who takes a shower, actually, and the biggest benefit it gives is to the market segment where the water consumption is the highest, such as bathing establishments, gyms, sports centers. Also, private households where the water consumption and the prices are high," said Mahdjoubi. The "out of this world" design has won several business and innovation Why does the author write the passage? A) To introduce a new technology B) To find a way to save energy C) To promote a new product D) To seek for investment
