There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to another. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move quickly (although your eye-lids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep.
A good title for this passage is______.

The Victorian Age, eminently represented by Dickens and Thackeray, was mostly regarded as
That does not mean it hasn't generated discussion. Several members of the Parliament opposed the measure as un-Asian. Others who acknowledged the problem of the elderly poor believed it a disproportionate response. Still others believe it will subvert relations within the family; cynics dubbed it the "Sue Your Son" law.
Those who say that the bill does not promote filial responsibility, of course, are right. It has nothing to do with filial responsibility. It kicks in where filial responsibility fails. The law cannot legislate filial responsibility any more than it can legislate love. All the law can do is to provide a safety net where this morality proves insufficient. Singapore needs this bill not to replace morality, but to Provide incentives to shore it up.
Like many other developed nations, Singapore faces the problems of an increasing proportion of people over 60 years of age. Demography is inexorable. In 1980, 7.2% of the population was in this bracket. By the turn of the century, that figure will grow to 11%. By 2030, the proportion is projected to be 26%. The problem is not old age per se. It is that the ratio of economically active people to economically inactive people will decline.
But no amount of government exhortation or paternalism will completely eliminate the problem of old people who have insufficient means to make ends meet. Some people will fall through the holes in any safety net.
Traditionally, a person's insurance against poverty in his old age was his family. This is not a revolutionary concept. Nor is it uniquely Asian. Care and support for one's parents is a universal value shared by all civilized societies.
The problem in Singapore is that the moral obligation to look after one's parents is unenforceable. A father can be compelled by law to maintain his children. A husband can be forced to support his wife. But, until now, a son or daughter had no legal obligation to support his or her parents.
In 1989, an advisory council .was set up to look into the problems of the aged. Its report stated with a tinge of complacency that 95% of those who did not have their own income were receiving cash contributions from relations. But what of the 5% who aren't getting relatives' support？ They have several options: (a) get a job and work until they die; (b) apply for public assistance (you have to be destitute to apply); or (c) starve 'quietly. None of these options is socially acceptable. And what if this 5% figure grows, as it is likely to do, as society ages.'？
The Maintenance of Parents Bill was put forth to encourage the traditional virtues that have so far kept Asian nations from some of the breakdowns encountered in other affluent societies. This legislation will allow a person to apply to the court for maintenance from any or all of his children. The court would have the discretion to refuse to make an order if it is unjust.
Those who deride the proposal for opening up the courts to family lawsuits miss the point. Only in extreme cases would any parent take his child to court. If it does indeed become law, the bill's effect would be far more subtle.
First, it will reaffirm the notion that it is each individual's -- not society's -- responsibility to look after his parents. Singapore is still conservative enough that most people will not object to this idea. It reinforces the traditional values and it doesn't hurt a society now and then to remind itself of its core values.
Second, and more important, it will make those who are inclined to shirk their responsibilities think twice. Until now, if a person asked family elders, cler
If I don't______them______I should probably forget all about them.
All that we really need to plot out the future of our universe are a few good measurements. This does not mean that we can sit down today and outline the future course of the universe with anything like certainty. There are still too many things we don't know about the way the universe is put together. But we do know exacdy what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it. Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard(调车场). All of the switches(转辙器) are set before the train arrives, so that its path is completely determined. Some switches we can see, others we cannot. There is no ambiguity if we can see the setting of a switch; we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we______.
