Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.

An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.

However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.

In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible?

Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents—today’s grandparents—would have called their children more often if the means and cost of doing so had not been a barrier.

Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.

Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

Our body clock, or natural body rhythm, influences our energy and alertness. Paying attention to it can help us choose the suitable time of the day when we best perform specific tasks.

The reality, however, is that most of us organize the time around work demands, school deadlines, commuting or social events. Doing whatever the body feels like doing is a luxury in today’s fast-paced modern society.

But that doesn’t mean it isn’t worth trying. Obeying our body clock has significant health benefits. Disrupting our natural body rhythm, on the other hand, has been linked to problems such as depression, obesity, or headache, says Steve Key, a biology professor.

When the body clock can synchronize (使…同步) the rhythms of its natural processes, it “gives us an advantage in daily life”, says Key.

According to him, when it comes to cognitive (认知的) work, most adults perform best in the late morning. As our body temperature starts to rise just before awakening in the morning and continues to increase until midday, our memory, alertness and concentration gradually improve.

However, he adds, our ability to concentrate typically starts to decrease soon thereafter. Most of us are more easily distracted (分心) between noon and 4 pm.

Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm, making that a good time for a nap.

Surprisingly, tiredness may increase our creative powers. For most adults, problems that require open-ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning.

When choosing a time of the day to exercise, paying attention to your body clock can improve results. Physical performance is usually best from about 3 to 6 pm, says Michael Smolensky, a professor of biomedical engineering.

Of course, not everyone’s body clock is the same, making it even harder to synchronize natural rhythms with daily plans.

1.If we know our natural body rhythm well, we can ______.

A. find out the suitable time to do specific tasks

A. Our alertness is influenced by our natural body rhythm.

B. Doing whatever your body feels like is very difficult in our modern society.

C. Obeying our body clock is good for our health.

D. Disrupting our natural body rhythm can lead to obesity.

3.Inspiration to solve a difficult problem will most probably come to us______.

A. when we get up in the morning

B. when we are tired in the evening

C. when we are full of energy in the late morning

D. when we are asleep at night

4. Which of the following can be the suitable title for the passage?

A. What is natural body rhythm?

B. Natural body rhythm is good for us.

C. natural body rhythm and health

D. The latest research about natural body rhythm.

Last summer I went through a training program and became a literacy volunteer. The training I received, though excellent, didn't tell me how it was to work with a real student, however. When I began to discover what other people’s lives were like because they could not read, I realized the true importance of reading.

My first student Marie was a 44-year-old single mother of three children. In the first lesson, I found out she walked two miles to the nearest supermarket twice a week because she didn't know which bus to take. When I told her I would get her a bus schedule, she told me it would not help because she couldn't read it. She said she also had difficulty once she got to the supermarket because she couldn't always remember what she needed. Also, she could only recognize items by sight, so if the product had a different label, she would not recognize it as the product she wanted.

As we worked together, learning how to read built Marie’s self-confidence. She began to make rapid progress and was even able to take the bus to the supermarket. After this successful trip, she reported how self-confident she felt. At the end of the program, she began helping her youngest son, Tony, a shy first grader, with his reading. I found that helping Marie to build her self-confidence was more rewarding than anything I had ever done before.

As a literacy volunteer, I learned a great deal about teaching and helping others. In fact, I may have learned more from the experience than Marie did.
