Researchers in a new field of science called chronobiology are studying the body’s natural rhythms, or patterns, to
find out just what makes people sleepy. Chronobiologists have learned that a person’s temperature, blood pressure, and
hormone levels go up and down in a regular pattern that repeats itself every twenty-four hours. The daily cycle of body
temperature affects how a person feels at different times during the day. For most people, body temperature begins to
drop in the early evening. This slows other bodily functions and makes you feel drowsy. Around daybreak, body
temperature rises and you begin to feel more alert.
Many chronobiologists now think that the time of day a person gets drug treatment for cancer affects the success o f
treatment. Other studies are revealing that we do different types of work better at different times of the day. Physical
coordination, for example, peaks during the afternoon. And some studies show that eight to nine hours of sleep every
night might not be necessary. Frequent naps might work just as well or even better. Findings such as these are helping
people to organize their lives so that they work with their natural rhythms rather than against them.
43 What do chronobiologists study?
The best time for people to get treatment. How our body reacts to temperature.
How our body works and why people feel sleepy. Efficient ways to improve our health.

Body temperature varies from day to day.
When body temperature decreases, our energy level also goes down.
The change of temperature has little to do with our bodily functions.
For most people, body temperature drops to the lowest in the early morning.
45 What does the word “drowsy” mean?
Sober Vigorous Hungry Sleepy
46 What advice will a chronobiologist give to doctors?
Studying their patients’ body patterns before giving drug treatment.
Sufficient sleep has a better healing effect than drugs.
Taking a nap before prescribing drugs.
Treatment carried out around daybreak is usually more effective.

Many single-child parents face a dilemma: whether or not to have a second child. Because there are no other
children in the family for an only child to associate with, he or she might feel lonely at times. Besides, it is often reported
that an only child may be more spoiled than one with siblings. A single child will not easily learn to negotiate with others,
leaving the child less capable of interacting well with people his or her own age.
However, for some single-child parents, particularly those with busy careers, the pressures of devoting time and
energy to a second child can seem too overwhelming. For other parents, the financial burden of having a second child
may be the prime consideration.
Advocates of single-child families argue that there are advantages for both the child and the parents. With just one
child, there is less potential for family arguments arising from favoritism. Moreover, the parents can give, and the child
can receive, more quality time and attention. This often leads to increased self-esteem and confidence.
Unfortunately, there is no simple answer to the question. The circumstances affecting each set of parents are unique,
and what is appropriate for one family may not be for another.
47 What is this passage mainly about?
The challenges parents face in child-raising. The pros and cons of having a second child.
Parents’ roles in children’s development. The growing concern about the declining birthrate.
48 Which of the following is NOT a reason why parents do not want a second child?
They have demanding jobs. They have low self-esteem.
They have a heavy economic burden. They don’t have enough time and energy.
49 Based on the passage, what would the writer probably agree on?
An only child is a naughty child.
Parents should have at least two children.
To have a second child or not is not a simple decision to be made.
Career women can afford to raise a second child.
50 What does the word “sibling” mean in the first paragraph?
A brother or sister A father or mother A nephew or niece An uncle or aunt
