Head injuries are often fatal, or of sufficient severity to require the hospitalization of victims. But there is a large group of people who sustain head injuries which can go undetected through ordinary medical examination. These are the people who seemingly recover from their injuries but still suffer subtle intellectual and behavioural effects that may seriously impair their ability to work and interact normally with other people. They are the victims of what experts call a “silent epidemic”. Some never lost consciousness and others never even suffered a direct blow to the head, yet brain damage occurred.
参考答案和解析
正确答案:
头部受伤往往会造成死亡或者重伤,需要让病人住院治疗。但是有许多人虽然头部受伤,医院的常规检查却发现不了。这些人受伤以后似乎得到了恢复,但是他们在智力或行为方面仍然有不易察觉的后遗症,这会严重影响他们的工作能力和与他人进行正常交往的能力。专家管这种人患的病叫做“不声不响的流行病”。有的人根本没有失去知觉,有的人甚至头部根本没有受到直接的撞击,然而脑子却受了伤。

Passage Five

Many superstitious people are afraid of black cats. They believe that black cats have a strange power. If a black cat crosses their path, they think they will have bad luck.

Black cats haven't always had such a bad reputation. Long ago, the Egyptians thought that black cats were holy animals. They even worshipped them. Pasht was an Egyptian goddess who had a woman's body and a cat's head. Because the Egyptians had so much respect for black cats, they often buried the sacred creatures with great ceremony. Mummies of cats have often been found in ancient cemetery ruins. To keep the cats company after they died, mice were sometimes buried beside them.

Feelings about black cats have always been strong. People have thought they were either very good or very bad. The people of Europe, in the Middle Ages, believed black cats were the evil friends of witches and the Devil. Witches were said to have the power to change themselves into black cats. People believed that you could not tell whether a black cat was just a cat, or whether it was a witch disguising herself as she plotted some evil scheme. The brain of a black cat was thought to be a main ingredient in witch's brew.

Unlike their ancestors of the Middle Ages, Englishmen today consider black cats to be good luck charms. Fishermen's wives often keep a black cat around so that their husbands will be protected when they are out at sea.

A. woman's head and a cat's body

第5题:

设有指针head指向的带表头结点的单链表,现将指针p指向的结点插入表中,使之成为第一个结点,其操作是______其中p^.next、head^.next分别表示p、head所指结点的链域。

A.p^.next:=head^.next; head^.next:=p

B.p^.next:=head^.next; head:=p

C.p^.next:=head; head:=p

D.head^.next:=head; p:=head


正确答案:A
解析:注意本链表是带表头附加结点的,因此表头结点的指针head^.next将指针为p的结点插入表头,即将原表头结点指针head^.next赋值给p所指向结点的链域p^.next,然后把p赋值给表头附加结点的链域head^.next。也就是两步撮作:p^.next:=head^.next;head^.next:=p。答案为选项A。
