During the hours when you labor through your work you may say that you're "hot." That's tree. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak. comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: "Get up, John! You'll be late for work again!" The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.
You can't change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you're sleepy in the evening but feel you must stay up late anyway. Counteract (对抗) your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in day, rise before your usual hour. This won' t change your cycle, but you'll get up steam (鼓起干劲) and work better at your low point.
Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on the edge of the bed a minute before petting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.
If a person finds getting up early a problem, most probably ______.
A．he is a lazy person
B．he refuses to follow his own energy cycle
C．he is not sure when his energy is low
D．he is at his peak in the afternoon or evening

The fork was an ancient agricultural tool, but for centuries no one thought of eating with it. Not until the eleventh century, when a young lady from Constantinpole brought her fork to Italy, did the custom reach Europe.
By the fifteenth century the use of the fork was widespread in Italy. The English explanation was that Italians were averse to rating food touched with fingers, "Seeing all men's fingers are not alike clean." English travelers kept their friends in stitches while describing this ridiculous Italian custom.
Anyone who used a fork to eat with was laughed at in England for the next hundred years. Men who used forks were thought to be sissies, and women who used them were called show - offs and overnice. Not until the late 1600's did using a fork become a common custom.
The custom of eating with a fork was ______ .
A．brought to Europe from America
B．begun when forks were invented
C．brought to Europe from Asia
D．invented by Italians
