阅读下列短文,从每题所给的四个选项中(A、B、C和 D)中,选出最佳选项,并在答题卡上将该项涂黑。
A
Most of us feel upset if we miss just one meal, and if we try to go without food for 12 hours we would really be uncomfortable. But there are some people who seem able to “fast” for very long periods.
Various records are claimed for long fast, but in most cases there is no medical proof and so the records are doubtful. One South African woman claimed that she lived for 102 days on nothinig but water and soda water.
There are great differences among living things in the ability to survive without food. For example , a tick(扁虱), which lives on animals, may survive a whole year. Warm-blooded animals use up their stores of food in the body more quickly.
In fact, the smaller and more active the animal, the more quickly it uses up its reserves. A small bird starves to death in about five days, a dog in about twenty. In general, we can say that a warm-blooded creature will die when it has lost about half its normal weight.
This matter of weight is important. Man and other creatures live in a state of metabolic equiplibrium(新陈代谢的平衡)which means maintaining the body weight once a certain point has been reached. This regulation of body weight is done by thirst, hunger, and appetite.
When your blood lacks nutritional materials, this registers(记录)in the hunger center of the brain and you feel “hungry”. The body is crying out for any kind of fuel(food). And it is our appetite that sees to it hat we chooose a mixed diet, which is the kind the body needs.
【小题1】According to this passage, a man will die _________.

A.when a certain point in losing weight has been reached.
B.when his blood lacks nutritional material
C.when his normal weight is lost
D.when he goes without food for more than 12 hours
【小题2】The word “fast” in Paragraph 1 can best be replaced by ________.
A.eat no foodB.live merely on water and soda water
C.live on nothingD.remains alive for a long time without food
【小题3】A tick can survive much longer than a bird because ________.
A.a tick lives on animalsB.a tick is much smaller
C.a bird is more activeD.both B and C
【小题4】A person feels hungry _________.
A.if he doesn’t choose a mixed diet
B.because his body cries out for food
C.when soemthing is wrong with regulation of body weight
D.if there are not enough nutritional in his blood
【小题5】From the passage we can infer that the author ________.
A.believes the South African woman very firmly
B.does not believe the South African woman at all
C.is not certain whether the South African woman’s claim was true.
D.is doubtful whether there was such a South African woman
