Some unwelcome visitors from North America have been turning up in the waters off the coast of Great Britain.

    North American lobsters (龙虾) have been found in the North Sea (between Great Britain and Northwest Europe), far from their own habitat. The lobsters usually live along the eastern coast of Canada and the United States.

    It is impossible that the lobsters could have made the 5,600-kilometre journey on their own. They were probably brought to Britain and then got away from containers. Some of the lobsters that were caught had elastic bands (松紧带) holding their legs shut, like lobsters that are kept in containers in stores or restaurants.

    Many may have been “set free” from some ships passing through the area. Sometimes passengers order a live lobster from a tank in the dining room and then ask the waiter to throw it overboard instead of cooking it.

    According to official records, 26 North American lobsters have been caught in waters off Great Britain since 1988. However, it is believed many more have been found but not reported.

    It is against the law to let North American lobsters come into British waters. If they settle down in European waters, it would be bad for the local lobsters. The two live in the same place and eat the same food. But North American lobsters are larger, stronger and more aggressive (好斗的) than European lobsters, and they produce young more quickly.

    As a result, they could take food and space away from the local lobsters, and from other types of shellfish that live in the same area. These lobsters may also carry diseases that could harm the local lobsters.

    After a year of examining many studies concerning whether homework is effective, NYC P. S. Elementary School decided that math worksheets and essay assignments were actually a waste of time. In February, Principal Jane Hsu sent a letter to parents stating that the Pre-K(学前班) through fifth grade students wouldn't be given any traditional homework to encourage kids to free time for reading, playing outside, or doing activities they enjoy.

    “The negative effects of homework have been well established.” Hsu wrote in a note to parents. “They include, children's frustration and exhaustion, lack of time for other activities and family time and, sadly for many, loss of interest in learning.”

    Some parents, however, disagree with the policy change, believing that a lack of focus will cause children to fall behind. Homework has been part of education from the beginning, and has increased in amount in recent years.

    Hsu's advice that children should read and spend time with their families has upset some parents to the point of considering pulling their children out of the school. This group feels that homework gives children a goal to work toward. Others feel so strongly about the importance of homework that they have begun giving their own homework to their children.

    An Australian Childhood Foundation survey finds that 71% of Australian parents feel they don't spend enough quality time with their children mainly because of the time spent running the household or the time spent helping with homework. Education experts in Australia are saying that parents should stop helping. Doing so will give kids more independence, give parents more free time, and help reduce the number of arguments caused by homework in the family.

    While some research suggests that homework has little academic benefit for elementary students, other researches show homework can help kids develop independence, and confidence. It can also contribute to a sense of belonging or control over their lives. When parents try to help their children with homework, the assistance can take away that feeling and can also make working parents more tired.

    In today's world of smart phones and notebook computers, most people have at least one time-telling thing with them. Since these digital products are so common, is time running out for the 500-year-old watch? According to some consumers, the answer is yes. New Jersey teenager Charlie Wollman says a watch is “an extra piece of equipment with no necessary function.” Many young adults think so and use their smart phones to tell time. It is said that fewer young people wear watches today than ten years ago. As a result, some people say that the watch industry is at a crossroads.

    However, watchmakers optimistically say that watches regain popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality watch that doesn't just keep good time. Fifty years ago, watchmakers took pride in their products' accuracy. But in recent years, the watch industry has changed itself into an accessory(附属的) business. And today, the image a watch communicates has become more important than the time it tells.

    “Complications” — features that go beyond simple timekeeping — are an important part of a watch's image. Today's watches offer lots of features that meet almost any personality. These features include compasses, USB drivers, and even other functions .

    Creativity also plays a key role in designing today's watches. For example, Japanese watchmaker Tokyoflash makes watches that don't even look like watches. The company's popular Shinshoku model uses different color lights to tell time. It looks more like a fashionable bracelet(手镯) than a watch.

    Whether a watch communicates fashion sense, or creative talent of a love sports, consumers want their watches to stand out. Nowadays, everyone has the same kind of gadget(配件) in their bags, so people want to make a statement with what' s on their wrists. Will this interest in wrist fashion last? Only time will tell!

    Facebook founder Mark Zuckerberg took out full-page ads in British and American newspapers on Sunday to apologize for the Cambridge Analytica scandal（丑闻）, admitting the quiz app built by a university researcher that leaked（泄漏）Facebook data of millions of people was a “betrayal of trust”.

    Since the scandal broke, the public has become more aware and concerned about how their online behavior may be used for purposes to which they have not agreed. It emphasizes the urgent need for better protection of personal information.

    To better protect personal data privacy（隐私）, targeted laws are needed. More effective cooperation should be carried out to protect people's privacy online as soon as possible.

    Countries, such as the United States and China in particular, which are global leaders in the use of big data should accelerate legislation（立法）on how it can be collected and for what purposes it can be used.

    At the same time, a closer watch should be kept on the world's major internet companies, such as Apple, Facebook, Amazon, Google, Microsoft, Alibaba, Tencent and Baidu to ensure they do not acquire unnecessary personal information or misuse the information they obtain. Despite the huge challenge such personal data protection may pose to their established profit-making models, these companies should know that the more powerful they are, the bigger responsibilities they shoulder.

    Strengthened efforts for personal privacy protection do not mean that big data must not be used, but that it is used appropriately. Big data is like a mountain or gold, and overemphasis on its security at the expense of its use will undoubtedly waste a valuable resource. The key problem is how to promote its use while guaranteeing people's privacy to be protected.

Comparing college entrance exams, there are different needs for admission. The national college entrance examination, or gaokao, is known as the most competitive test for Chinese students. Do students in other countries also need to take a standardized test to get into university?

South Korea holds the College Scholastic Ability Test（CSAT） in November each year. The CSAT plays an important role in the country's education. On test day, bus and subway frequency increases to make sure that students can get to the test sites in time.

Japan is trying to reform its standardized national college entrance exam. In January 2022, Common Test for University Admissions took the place of the National Center Test for University Admissions, which had been adopted since 1990. The new exam aims to put emphasis on the ability of students to discover and solve problems by themselves.

The American College Test（ACT） and Scholastic Assessment Test（SAT） are the two main college entrance exams taken by students in the US. While SAT tests a student's ability to learn, the ACT tests a student's educational development. Both tests normally take place seven times throughout the year. Students can retake the exams for a better score.

In the UK, there's no standardized test for college admission. Instead, each college has their own admission criteria. These criteria often onlyinclude submission of transcripts（成绩单） and participation in an interview. Yet, there are subject-specific exams used by some colleges.
