What will our future look like? People have always been wondering about this question. Go on reading this text and you will know what will happen in the next fifty years.

    How can we know what the future will look like? To be able to understand the future, you must know the past. What has taken us to where we are today and what has changed along the way? The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago. Will this change in the next 150 years? No.

    What inventions have really made a difference in the last 150 years? In the past years, the inventions that have affected most people around the world for everyday living are the telephone, electricity, radio, television, computer, the car and the ability to communicate through the Internet. Then we of course have a lot of inventions that have made life easier, like new medicine, faster transports etc. In general, human beings have been working hard in the last 150 years to make the inventions so that they will be able to get control of the time and the world. Since there is still much to do in this area, this will be the focus at least for the next 150 years.

    Why do we need to predict the future? Predicting the future is important for two reasons: first we need to start to think about what kind of what kind of future we would like for ourselves and to pass on to the next generation, and then we need to know what decisions we need to make today that will give the best result in the future.

    Enough sleep is important to health. The amount of sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups. Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgement to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day's work.

    Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation (放松).

    Ability (能力) to sleep lies largely in habit. The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance (避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.

    A bath at bedtime, neither hot nor cool but of body temperature may be helpful to sleep. Sleep-producing drug (药) should never be taken except when suggested by a doctor.

    A primary school in Jinhua, Zhejiang Province has announced it no longer requires parents to sign their children's homework, which was aimed at getting parents to supervise(监督) their children after school. China Youth Daily comments: Putting an end to the requirement that parents sign off on the homework of their children eases the burden on many parents, as otherwise they would have to do primary school homework after a hard day's work. But there are worries that if parents stop having to sign off on their children's homework, the children will not get good grades.

    However, the most effective way for children to study is to develop their willingness to learn and do their own studies. When doing homework, students practice and hopefully apply what they have learned. It is true that teachers are supposed to check students' homework and identify their mistakes. But some parents correct their children's mistakes by themselves when signing off on it.

    It is the duty of students to do their homework, be responsible for their studies and correct their mistakes. Parents' supervising their homework, checking their answers and dealing with the harder problems will only make children less aware of their mistakes and encourage them to wait for their parents' help when they face any problems.

    Children have to manage their own learning and develop the ability to study by themselves, as competence will not be achieved if a student simply repeats strict tasks in which he is assisted in school by teachers and at home by parents.

    A delayed satisfaction experiment conducted by Walter Mischel in the 1960s proved that children with better self-discipline(自律) performed better in their studies and interpersonal relationships.

    There is little doubt that parents' supervision can make children's homework better. But it does not give children the chance to practice their ability to solve problems independently.

    THREE years ago Jenny Salgado, a Dominican shop assistant, moved to Highland town, a neighborhood of Baltimore. When she arrived the shop she works in, it was one of only a few Spanish businesses. Now there are many more. "It's good now if you speak Spanish," she smiles.

    Baltimore has been losing people for 60 years. To address this, its mayor, Stephanie Rawlings-Blake, wants to make it the most immigrant-friendly city in the world. Its libraries provide Spanish-language exercise classes. To help those with no papers, the city is introducing micro-loans (小额贷款) which require no credit checks; city police would no longer routinely check the immigration status of citizens or enforce any federal immigration law unless required to. The then governor, Martin O'Malley made it possible for illegal immigrants to get driving licenses.

    Such welcoming policies are spreading. Such cities as Cleveland, Dayton and Philadelphia all eagerly try to please immigrants. Rick Snyder, the governor of Michigan, has asked the federal government to offer 50,000 visas to people who agree to live in Detroit. His administration has made it easier for skilled migrants to get professional licenses.

    When a city's population falls, both tax receipts and services fall. Half-deserted neighborhoods breed (滋生) crime, driving yet more people to leave. No city has escaped this death circle without attracting new residents, says Steve Tobocman of Global Detroit.

    Several studies suggest that when immigrants arrive, crime goes down, schools improve and shops open up. In Detroit, immigrants living near the tiny separate city of Hamtramck have formed local watches to guard against thieves. Their neighborhoods are not just safer; they are also among the only places where it is as easy to buy fresh vegetables as drugs and alcohol.

    But attracting new immigrants to the cities which most need them is hard, argues Audrey Singer of the Brookings Institution. They care about the same things as everyone else: safe streets, good schools and jobs. Cities which have lost population for decades struggle with all of these.
