问题 单项选择题 B型题

癌前病变()

A.乳腺导管内癌

B.结肠腺瘤性息肉病

C.胃中分化腺癌侵及黏膜下层

D.卵巢交界性黏液性囊腺瘤

E.子宫颈重度非典型增生

答案

参考答案:B

解析:原位癌指的是异型增生的细胞在形态和生物学特性上与癌细胞相同,并累及上皮的全层,但没有突破基底膜向下浸润;如果癌细胞突破基底膜向深层浸润,则为浸润性癌;上皮内瘤变用来描述上皮从非典型增生到原位癌这一连续的过程,临床上将重度非典型增生和原位癌统称为上皮内瘤变Ⅲ级;交界性肿瘤指的是某些组织类型的肿瘤(如卵巢浆液性肿瘤),除了有典型的良性肿瘤(如卵巢浆液性 * * 状囊腺瘤)和恶性肿瘤(如卵巢浆液性 * * 状囊腺癌)之分,还存在一些组织形态和生物学行为介于两者之间的肿瘤,如卵巢交界性黏液性囊腺瘤。

完形填空
One summer several years ago, my family was enjoying a barbecue on the beach. After the barbecue, my father-in-law invited me to go fishing.  Fishing was his hobby, but I   36  went fishing. We walked a little way along the beach and reached a rock by the shore, and I    37   the hook into the sea from there.  Frankly speaking, I am a (n)   38  person, and although I had not felt a tug (猛拽) on the line, I reeled up the hook after five minutes or so. I had caught    39 . It was a starfish. It trembled uneasily when I   40  the hook from its ugly mouth. I threw the starfish back into the sea. After another five minutes I caught another starfish and I threw it back again.
After a while, I caught yet another starfish. That was  41  time, and this time I really got angry. I hit the starfish on the rock   42  throwing it into the sea. I was not in the   43  to continue fishing any more.
When I was   44  the fishing tools, I noticed a little girl looking at the starfish on the rock. We   45  looks with each other. The little girl spoke to me in a   46  voice. “Sir, would you mind if I   47  the starfish back into the sea?”“Not at all,” I replied. “"But you know, there are too many starfish in the sea, and they eat many shellfish.   48 , they look so ugly. I don't like them.”
“I understand,” said the little girl. “But if the starfish cannot get back to the sea, it will be   49  by the sun and die. My dead grandfather once told me that there are no living creatures that have no right to exist in the world. God   50  every creature because it was needed by nature. Poisonous snakes, spiders, and starfish were born into this world with a certain   51  for their existence.”
“All right, dear, please throw the starfish back into the sea,” I said to the little girl, feeling   52 . The girl picked up the starfish and gently put it into the sea, and she  53  at me and said, “Thank you, sir.”
Many people like "cute" creatures such as dogs, cats, and rabbits, while they tend to dislike “ugly” creatures such as snakes, spiders, and starfish.  However, the “cuteness” and “ugliness” of things are decided   54  only on one’s personal opinions. There are no living creatures that have no  55  in the world-- this is what I learned from the little girl.
