　　(2009年东北三校第一次联考)My son was badly hurt in a fire. After he __1__from a series of treatments, the doctors told him they would not do any operation for six months __2__it took long for the skin to stop shrinking(收缩). So, he had to return to college with a visible 10­inch__3__on his face.

　　I said to my son，"Keaton, __4__will pay any more attention to your scar __5__you do. If it does not bother you, it will not bother __6__. "He took my advice to heart and returned to school with his head __7__high-glad he was alive.

　　__8__，everyone has scars and shortcomings. Some of you may spend much time thinking that people would like you better，__9__you looked different, or dressed differently, or could have a different and newer __10__.

　　But you see, like Keaton's scar, people will only judge you by your looks, or your __11__，or your car, if you are judging yourself by these same false __12__.

　　One of my friends in college was very __13__. At first, when people met him, they noticed his __14__for about 10 seconds. This man felt __15__about himself and spent most of his time __16__about other people's comfort and welfare. __17__， people ignored his looks. What people __18__was his kindness and his concern for them. He didn't act in an ugly way so people didn't treat him as an ugly man.

　　Therefore, concentrate on what you value __19__yourself, because if you can see that beautiful person, everyone you are in contact with will see the same __20__.

　　1. A. cured　　　B. recovered　　C. improved　　D. returned

　　解析：选B。上一句提到儿子在一次大火中被严重烧伤，由此可知此处应用recover，表示经过一系列治疗，他"康复"了。假如选择A项，应变成被动形式。

　　2. A. because B. though C. until D. before

　　解析：选A。本句的前半部分提到医生告诉他六个月内不能再做手术，后半部分解释的是其中的原因，所以空格处表示的是因果关系。

　　3. A. cut B. wound C. injury D. scar

解析：选D。由于暂时无法进行手术，他的脸上有一道十英寸长的清晰可见的"伤疤"。下一段前半部分中的scar也是线索提示。cut表示"伤口"；wound多用来表示刀伤或枪伤；injury多指(对躯体的)伤害，损伤。
