On the arrival of the graduation season, a large number of students will leave their colleges and get busy finding jobs. However, it seems not all students will be in a hurry to get to work. According to a survey online in May, about 9.8 percent of the 93,420 graduates surveyed said they wouldn't begin working right after graduation. This phenomenon is called "delayed employment".

    One reason why the graduates don't start their careers immediately is that they want a job related to their personal interests, and they are unwilling to give in and take jobs they don't like. "Looking for the right career is like looking for Mr. Right. Maybe I could have found a job or two, but I don't want to just make a living or be stuck in a specific position,” said Shen Yu, who graduated in 2014 but didn't look for a job right away.

    Another reason is to avoid the fierce competition of the job market.Statistics provided by the Ministry of Education show the number of the new university graduates will reach 7.95 million this year. Meanwhile, only 26.7 percent of the new graduates have signed contracts(合同) with employers, 8.7 percent down from the previous year.

    And some Chinese college students have chosen to travel or volunteer instead of finding jobs. For example, Chen Nuan, who will graduate from the Shanghai Institute of Visual Arts this summer, has planned to tour Europe immediately after graduation. "As the old Chinese saying goes,traveling thousands of miles is better than reading thousands of books,"she told China Daily.

    However, no matter what you choose after graduation, make full use of the first few years—this is when people develop soft skills such as punctuality and teamwork. The first 10 years are essential, which shapes careers in the long term.

    From July to October every year, about a quarter of the world's blue whales feed in the Pacific Ocean off the coast of California. But the whales currently face a major threat in their favorite feeding area. Ships carrying cargo (货物）sail in the same area at the same time. All too often, the whales' paths and the ships' travel lines overlap (重叠), and a ship will hit a whale.

    According to a new study, these ship strikes have become a serious threat to the overall population of the world's blue whales. Only about 10,000 of the creatures still exist worldwide. Blue whales are the largest known animals ever to live on Earth. Even so, if hit by a container ship, a blue whale will likely die from its injuries.

    In 2007 alone, large ships killed five blue whales in the waters off San Francisco and Los Angeles, California. The National Oceanic and Atmospheric Administration (NOAA) says that because there are so few whales already, losing three to five from the California whale population every year is a significant loss. “The estimated population of blue whales in this part of the Pacific is 2,500”, says Sean Hastings, a NOAA analyst. “So every whale counts toward this species moving off the endangered-species list.”

    Now, marine scientists must figure out how to protect the whales from the giant container ships. One very simple program is already under way in the Santa Barbara Channel, a waterway that separates mainland California from the nearby Channel Islands.

    The Channel Islands National Marine Sanctuary has asked large container ships passing through the area to voluntarily slow down. Sailing slower will allow the ships‟ crew (船员）more time to change course before hitting a whale.

    Several of the world's largest shipping lines are set to participate in the new program. For every ship that passes through the Santa Barbara Channel at or below the reduced speed of 12 knots (海里/小时）, the company that owns the ship will be paid $2,500.

    Scientists in Britain have managed to teach bumblebees(大黄蜂) to pull strings to get to food and then pass on what they have learned to others in their colony(群体)—showing a high level of intelligence despite their tiny brains.

    Researchers at Queen Mary University of London said the experiments, often used to test the intelligence of apes (猿) and birds, showed for the first time that some insects are up to the task, and can also pass skills on through several generations.

    The findings add to the evidence suggesting the ability for “culture spread” — the ability to learn and pass on knowledge and skills — may not be exclusive to humans.

    In the research, published in the journal PLOS Biology on Tuesday, the scientists were able to train 23 out of a group of 40 bees to pull strings with their legs and feet.

    The strings were attached to discs — or artificial “flowers” — containing food at their center but placed under a transparent screen. The bees, spotting the food beneath the screen, learned to pull the “flowers” out by pulling the string with their legs and feet to be able to get to it.

    From another group of bees given the chance to solve the task without any training, only two of 110 were successful.

    Another group of bees was then allowed to observe the trained bees pulling the strings, and 60 percent of them successfully learned the skill. Finally, trained bees were put in colonies, and the scientists found the technique spread successfully to a majority of the colony's worker bees.

    Lars Chittka, a Queen Mary University professor who guided the project, said the team is interested in figuring out the brain processes behind the bees' learning and teaching skills.

    The health of millions could be at risk because supplies of medicinal plants are being used up. These plants are used to make traditional medicine, including drugs to fight cancer. “The loss of medicinal plants is a quiet disaster,” says Sara Oldfield, secretary general of the NGO Botanic Gardens Conservation International.

    Most people worldwide rely on herbal (药草制的) medicines which are got mostly from wild plants. But some 15,000 of the 50,000 medicinal species are under threat of dying out, according to report from the international conservation group Plantlife. Shortages have been reported in China, India, Kenya, Nepal, Tanzania and Uganda.

    Over-harvesting does the most harm, though pollution and competition from invasive species (入侵物种) and habitat destruction all contribute. Businessmen generally harvest medicinal plants, not caring about sustainability (可持续性),” the Plantlife report says, “damage is serious partly because they have no idea about it. but it is mainly because such collection is unorganized” Medicinal trees at risk include the Himalayan yew (紫衫) and the African cherry, which are used to treat some cancers.

    The solution, says the report's author, Alan Hamilton, is to encourage local people to protect these plants. Ten projects studied by Plantlife in India, Pakistan, China, Nepal, Uganda and Kenya showed this method can succeed. In Uganda, the project has kept a sustainable supply of low-cost cancer treatments, and in China a public-run medicinal plant project has been created for the first time.”

    “Improving health, earning an income and keeping cultural traditions are important in encouraging people to protect medicinal plants,” says Hamilton, “You have to pay attention to what people are interested in.”

    Ghillean Prance, the former director of the Royal Botanic Gardens at Kew in London, agrees that medicinal plants are in need of protection. “Not nearly enough is being done,” he told New Scientist. “We are destroying the very plants that are of most use to us.”

    American college students are becoming more adventuresome as they study abroad, showing less interests in English-speaking destinations such as Great Britain and Australia and more in such countries as China, India, Argentina and Brazil.

    Britain remained the most popular study destination in 2005, according to annual figures from the Institute of International Education, followed by Italy, Spain and France. But the number of American students studying in Britain and Australia descended a little, even as the number of American students abroad rose by 8%. The growth came in non-English speaking European countries and in Asia. China is now the eighth most popular destination for American students, attracting nearly 6,400 in 2005, up 35% from the number of the year before. Argentina and India saw increases of more than 50%.

    Allan Goodman, president of the Institute of International Education, said that a range of factors contributed to the trend, from growing awareness of globalization after the terrorist attacks on September 11, 2001, to programs such as former President Bush's National Security Language Initiative, which trains soldiers, intelligence officers and diplomats in foreign languages. “What Americans are doing is waking up and discovering there's a world out there,” he said.

    Other figures showed the flow of students in the opposite direction, from foreign countries into American universities. The institute found that international enrollment (入学) in American higher education remained steady at about 565,000. The figures are of keen interest to universities, which depend on foreign students for teaching and research help, and to policy-makers, who consider it important, as future foreign leaders may be familiar with the United States. The year of 2005 saw big increases in students from South Korea, Mexico and Taiwan of China. India sends the most students and China is No.2. Other countries that show large percentage increases in the number of students sent to the US include Nepal and Vietnam, while Japan, Turkey and Malaysia saw declines. About 58% of international students in the US come from Asia.

    We are all busy talking about and using the Internet, but how many of us know the history of the Internet?

    Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.

    At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" the Internet more convenient.

    Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.

    The Internet has now become one of the most important parts of people's life.
