In cities with rent control, the city government sets the maximum rent that a landlord (房东) can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartment. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city.

    Some experts argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

    Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.

    Economic theory predicts the results of economic decision, such as decisions about farm production, rent control, and the minimum wage. The predictions may be corrected only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.

    Kettle's Yard, Cambridge

    This modern-art gallery in a Victorian house was founded in the 1950s by Tate Jim and reopened in February following a two-year redevelopment by Jamie Fobert Architects, the team behind the 2017 Tate Steves extension. This means a new cafe, a four-floor education wing and improved gallery space that can accommodate more visitors. The gallery's permanent collection includes works by Joan Miró, Henry Moore and Barbara Hepworth.

    Being Brunel, Bristol

    To celebrate the life and work of famous civil engineer Isambard Kingdom Brunei, Being Brunei will open in March on Bristol's harbourside. The museum will include a range of interactive and entertaining exhibits, including talking portraits of his friends and family and personal possessions, including an 1821 school report. It is a good place for families to strengthen connections.

    Royal Academy of Arts, London

    The RA reopens on 19 May for its 250th anniversary, following a £50m renovation (翻新) with a gallery and expanded exhibition programme. These will include three day-lit galleries, which will host exhibitions with a focus on contemporary art and architecture. The grand frontwall of the Burlington Gardens building has also been restored—possibly the first time it's had a proper clean in its 150 year history.

    V&A, Dundee

    One of the most significant new openings of the year will be Scotland's first design museum and also the first V&A anywhere outside of London on 15 September. The museum building sits on the river Tay. It will celebrate Scottish design and objects in its collection.

    The Ig Nobel Prizes praise research that makes you laugh and then think. The winners are allowed to make a one-minute speech with time kept by an eight-year-old! Every year, in Harvard's Sanders Theatre, people watch the winners step forward to accept their prizes. These are physically handed out by real Nobel laureates (获得者). Let's have a look at some of them.

    The Empty Bladder (膀胱) Experiment

    Four researchers at Georgia Institute of Technology found that animals above 3 kg empty their bladders in about 21 seconds. What is the purpose of this study? The researchers hope this will help solve urinary (泌尿的) problems in animals.

    The Science of Eggs

    A team of Australian scientists managed to get hard-boiled egg whites to become raw again. While it sounds silly, this research could have a serious influence on cancer (癌症) research.

    The Fascination with Animals

    Charles Foster and Thomas Thwaites from the UK shared the 2016 Ig Nobel Prize in Biology. Thomas chose to live like a goat and wrote about his experience in "GoatMan: How I Took a Holiday from Being Human". Charles, on the other hand, spent some time in the wild, trying out the lives of many animals. He felt it gave him a chance to explore the world around us with more of our senses.

    Colors & Horseflies

    A team from Hungary, Spain, Sweden and Switzerland won the 2016 Ig Nobel Prize in Physics. They studied why horseflies have less interest in white-haired horses. The team used handmade horses covered in glue. They found that dark colors attracted more flies because of how sunlight reflected (反射) off them. To the food searchers, it was a sign of food. This finding could explain the white coats of zebras too.

    Many languages are disappearing and languages such as English, Spanish and Chinese are increasingly taking over. Yet Maori promises to have a rosy future given that New Zealanders are showing great enthusiasm for speaking this local language.

    A "Maori renaissance (复兴)" blossomed in the 1970s as language activists championed their cause and Maori fought for greater political power. But until 2013, just 3.7 percent of New Zealanders spoke the language fluently, and many predicted it would soon die out. Now New Zealand's government is erasing prejudice and struggling to increase the percent of population who can speak basic Maori by 2040 to 20. Prime Minister Jacinda Ardem said last month that her newborn daughter would learn both Maori and English. "It's an official language, so why should we dismiss its universal availability and its much more common use?" said Ms. Ardem, adding that she also planned to study the language. Grassroots are also spreading it by word of mouth Answering the phone with the greeting "kiaora" (hello) or ending an email withunga mihi' (thanks) has become a fashion. Maori is gradually becoming part of New Zealand's mainstream popular culture.

    Ajit Kumar Samah, a famous professor in Auckland University, published a book—Coniagious: why Maori catches on, where he introduces readers to the popularity of Maori and expresses his great anxiety for the lack of teachers who have the competence to teach the Maori language.

    People are not on the same wavelength, however. Suggestions on officially replacing English-language place names with traditional Maori ones have been rejected. So when a police car was designed using Maori, it was condemned by some as ridiculous because of the higher Maori rates of arrest and imprisonment.

    Perhaps you have heard a lot about the Internet, but what is it, do you know? The Internet is a network. It uses the telephone to join millions of computers together around the world.

    Maybe that doesn't sound very interesting. But when you've joined to the Internet, there are lots of things you can do. You can send e-mails to your friends, and they can get them in a few seconds. You can also do with all kinds of information on the World Wide Web (WWW).

    There are many different kinds of computers now. They all can be joined to the Internet. Most of them are small machines sitting on people's desks at home, but there are still many others in schools, offices or large companies. These computers are owned by people and companies, but no one really owns the Internet itself.

    There are lots of places for you to go into the Internet. For example, your school may have the Internet, you can use it during lessons or free time. Libraries often have computers joined to the Internet, you are welcome to use it at any time.

    Thanks to the Internet, the world is becoming smaller and smaller. It is possible for you to work at home with a computer in front, getting and sending the information you need. You can buy or sell whatever you want by the Internet. But do you know 98% of the information on the Internet is in English? So what will English be like tomorrow?
