    It's a sadness shared by many business start-ups: why did my company fail, while so many others seem to be profiting from the “golden age of entrepreneurship (创业精神）”？

    Some people argue that opportunities and good fortune are the secrets to success. But Innovation Works CEO Kaifu Lee believes that entrepreneurs need to have certain qualities to help them face the difficulties of starting a business. At a recent LinkedIn conference, Lee mentioned some of these qualities.

    “Even though we're now in a golden period for innovation and start-ups, not everyone is meant to be an entrepre- neur. Entrepreneurs share the same qualities — they are confident, communicative and focused. They don't fear losing, and they are good at learning,”he said.

    Lee explained that he often meets young people who are irresolute about setting up a business.“ If that's the case for you then don't do so,” he said at the conference. The bottom line, he said, is that entrepreneurs should be determined and passionate.

    Passion is vital to entrepreneurs since it typically relates to self-motivation, according to Li Jun, 26, founder of Wuhan Lushenglin Plant Wall Co Ltd. “Entrepreneurs often need to work around the clock. It's easier for people to put up with the difficult schedule if they're passionate about what they're doing,” he said.

    Entrepreneurs are also generally thought of as risk-takers. But Yu Xiuhong, general secretary of the Bright China foundation, warns that young entrepreneurs should not take too many risks. “Successful entrepreneurs rarely take risks blindly or jump at opportunities others avoid. Before launching a business, it's advisable to do market research, evaluate yourself and your opponents,” she said.

    Also she advises that young people thoroughly calculate their expenses in advance. Take Li Dongjin as an example, 35-year-old long-term entrepreneur disappeared a week ago after his O2O car washing company failed disastrously. He had gotten an initial investment of 5 million yuan but wasted it all on allowance and publicity.

    You may be surprised to learn that English gets 30 to 45 percent of its words from French. The reason goes back to the year 1066, when Norman forces invaded（入侵）what is now Britain. The Normans were from northern France and spoke French. During the Norman occupation, French became the language of England's rulers and wealthy class. This lasted for more than 300 years. Other people in England continued to speak English during this period.

    Over time, the two languages combined and shared words. Some researchers believe that about 10,000 French words eventually entered the English language. However, although English took many French words, their meanings have not always stayed the same. Sometimes the differences in meanings can be very important, and lead to funny or strange situations if the words are used in the wrong way.

    Take, for example, the French word college. In English, college can often be used in place of the word university, or sometimes as a school within a university. However, in French, college actually means “middle school”, or the level of schooling for students in grades five or six through eight.

    There are many other similar words in the two languages with completely different meanings. In English, the word chat is a verb which means “to talk casually”; but in French, the word chat is the word for an animal: a cat.

    If an English speaker says someone is jolly, that means they are cheerful or friendly. But in French, jolie means someone is good-looking or pleasant to look at. In any case, both are nice things to say to someone.

    If you are interested in studying at an American university, you have to take the Test of English as a Foreign Language. The test is widely known as the TOEFL. It is the most widely used language exam for American universities.

    There are two major kinds of the TOEFL test. The first is the IBT, or Internet-based Test. It is offered in most of the world and accepted by nearly every university and scholarship program in the United States. The other kind of the test is called the Paper-based Test or PBT. The PBT is less costly to take and does not require use of the Internet.

    But how to get started with TOEFL? Here are some tips.

⒈Plan ahead —It takes a long time to improve your TOEFL score. Do not expect a big lift in your test results after two weeks. You will have to spend a lot of time and energy.

⒉Master the basics first —You should have to be good at basic English before you take the test. If you score below 500 on the PBT or 70 on the IBT, study for a few months and come back to the TOEFL later.

⒊Get a study guide — It is easy to find study guides for the IBT. Pearson, Barron's, ETS, and Kaplan all produce quality materials. Take a practice test once or twice a month. The best study guides will have explanations in the answer key.

⒋Use outside resources — Remember, you are learning a language, not a test. You can improve your TOEFL score by making English part of your daily life. Some simple ways are listening to English speakers, watching movies and reading newspapers. Some others are reading English textbooks, sending and reading text messages in English, and writing online in English.

    The best way to do well on the TOEFL is to know English well. The real goal of the test is to measure how well a student can communicate in English-speaking classroom.

    Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures（核心体温）in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity（湿度）.

    In very cold climates, there is a constant danger of developing hypothermia（低体温）, which is a life threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9—15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.

    In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life threatening hyperthermia typically starts in humans when their temperatures rise to 40.6—41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.
