How to Manage Your Phone's Data Use

    Smart phones give you access to a wealth of information and media, but most networks put a limit on the amount of data you can use each month. A typical phone contract includes a data allowance of between 500MB and 10GB per month. {#blank#}1{#/blank#} You see, your usage can mount up surprisingly quickly – watching a film on the phone is about 700MB in SD, an hour of streaming TV is around 500MB or 60-140MB for the same of radio, chatting on Skype for an hour is around 40MB. {#blank#}2{#/blank#}

    If possible, wait until you can connect to free Wi-Fi before using your phone's data features.

    When you are on the road, use your car's GPS, not your phone, to find the way. {#blank#}3{#/blank#} But maps are preloaded in a GPS, making this free to use.

    {#blank#}4{#/blank#} Many of these are funded by ads that pop up on your screen. Every ad has to download through your network, using up your data allowance.

    If you regularly need to use a lot of data on your phone, consider a data-compressing(压缩) app, such as Onavo(www.onavo.com). {#blank#}5{#/blank#} So you use less of your monthly allowance. You may have to subscribe to such compression services, so you'll need to weigh up whether it's worth the cost.

    In colleges around the country, most students are also workers.

    The reality of college can be pretty different from the images presented in movies and television. Instead of the students who wake up late, party all the time, and study only before exams, many colleges are full of students with pressing schedules of not just classes and activities, but real jobs, too.

This isn't a temporary phenomenon. The share of working students has been on the rise since the 1970s, and one-fifth of students work all year round. About one-quarter of those who work while attending school have both a full-course load and a full-time job. The arrangement can help pay for tuition (学费) and living costs, obviously. And there's value in it beyond the direct cause: such jobs can also be critical for developing important professional and social skills that make it easier to land a job after graduation. With many employers looking for students with already-developed skill sets, on-the-job training while in college can be the best way to ensure a job later on.

But it's not all upside. Even full-time work may not completely cover the cost of tuition and living expenses. The study notes that if a student worked a full-time job at the federal minimum wage, they would earn just over $15,000 each year, certainly not enough to pay for tuition, room, and board at many colleges without some serious financial aid. That means that though they're sacrificing time away from the classroom, many working students will still graduate with at least some debt. And working full time can reduce the chance that students will graduate at all, by cutting into the time available for studying and attending classes.

There is little reward for attending but not finishing college. Students who wind up leaving school because of difficulty in managing work and class are likely to find themselves stuck in some of the same jobs they might have gotten if they hadn't gone at all. The difficulty of working too much while in school can create a cycle that pushes students further into debt without receiving any of the financial or career benefits.

    Harvard University in the United States has been ranked as the university with the best “reputation” in the world.

    The Times Higher Education magazine has listed 200 top universities all over the world based on how they are regarded by a group of international college teachers. That is to say, the list measures how universities are regarded, rather than how they actually performed.

    “A subjective, word-of-mouth (口碑的) quality such as “reputation” has genuine economic value for universities,” said Simon Marginson, professor of higher education at the University of Melbourne in Australia.

    “Reputation is not just an impression, though it might not be as reliable as performance by objective indicators (客观指标),” said Prof Marginson.

    Based on the views of 13,000 college teachers around the world, it confirms the power of the big US universities, which dominate this list. Seven of the top 10 are US universities, headed by Harvard and Massachusetts Institute of Technology (MIT). Furthermore, 14 of the top 20 are from the US. Cambridge is the highest ranking UK university in the list, in third place, with Oxford ranked as sixth.

    “For students applying to university, reputation might be hard to quantify, but was an important part of the attractiveness,” said the president of Cambridge University's students' union, Rahul Mansigani.

    “Reputation makes a huge difference. If there is an idea that somewhere is great, it will get lots of good people applying whether it's true or not. Factors such as a sense of history and the presence of outstanding college teachers were part of the reputation of Cambridge,” he said.

    In general, people talk about two groups of colors: warm colors and cool colors. Researchers in psychology think that there are also two groups of people: people who prefer warm colors and people who prefer cool colors.

    The warm colors are red, orange and yellow. Where there are warm colors and a lot of light, people usually want to be active. People think that red, for example, is exciting. Sociable people, those who like to be with others, like red. The cool colors are green, blue and violet. These colors, unlike warm colors, are relaxing. Where there are cool colors, people are usually quiet. People who like to spend time alone often prefer blue.

    Red may be exciting, but one researcher says that time seems to pass more slowly in a room with warm colors than in a room with cool colors. He suggests that a warm color, such as red or orange is a good color for a living room or restaurant. People who are talking or eating do not want time to pass quickly. Cool colors are better for offices or factories if the people who are working there want time to pass quickly.

    Researchers do not know why people think some colors are warm and other colors are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue, and violet are cool. Perhaps warm colors remind people of warm days and the cool colors remind them of cool days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.

Dear Mom and Dad,

    I'm afraid I have some very bad news for you. I have been very naughty and the school master is very angry with me. She is going to write to you. You must come and take me away from here. She does not want me in the school any longer. The trouble started last night when I was smoking a cigarette in bed. As I was smoking, I heard footsteps coming towards the room .I did not want a teacher to catch me smoking, so I threw the cigarette away. Unfortunately, the cigarette fell into the waste--paper basket. It caught fire.

    There was a curtain near the waste --paper basket. It caught fire too. Soon the whole room was burning. The master phoned the fire brigade. The school is a long way from the town and before the fire brigade arrived, the whole school was on fire. The master said that the fire was all my fault and I must pay for the damage. She will send you a bill for about a million dollars.

    I'm very sorry for this.

    Much love

Sarah

    Eating chips, chocolates and cakes may damage a child's intelligence, according to researchers at Bristol University. Their study suggests a link between diet high in processed(加工的) food and a slightly lower IQ. Writing in the journal of Epidemiology and Community health, they suggest poor nutrition may affect brain development.

    The eating habits of 3,966 children taking part in the Avon Longitudinal Study of Parents and Children were recorded at the ages of three, four, seven and eight and a half. The researchers said three types of diet appeared: processed diet which was high in fat, sugar and fast food, traditional diet of meat, potatoes and vegetables, and healthy diet of salads, fruit and fish. The children all took IQ tests when they were eight and a half.

    The researchers found a link between IQ and diet, even after taking into consideration other factors such as the mother's level of education and social class. Diet high in processed food at the age of three was linked to a slightly lower IQ at the age of eight and a half, suggesting early eating habits have a long-term influence. Dr Pauline Emmett, who carried out the study at Bristol University, said, “Brain development is much faster in early life, and it's when it does most of its growing.”

    Although the relationship between diet and IQ was very strong, the influence was quite small. Processed food was linked with IQs only a few points lower. Experts in the field said the results had shown common sense was right. Fiona Ford, spokesperson for the British Dietetic Association, said, “It's well worth looking at the long-term influence of diet, for everyone's familiar with the short term. The research agrees with the type of advice we already know, but that's not always enough. Sometimes a society has to help a person change; we need to educate more young parents about healthy eating.”
