问题 单项选择题

属于免疫性溶血性贫血的疾病是()

A.蚕豆病

B.地中海贫血

C.冷凝集素综合征

D.阵发性睡眠性血红蛋白尿症

E.遗传性球形红细胞增多症

答案

参考答案:C

解析:蚕豆病是由于红细胞酶缺陷所致;地中海贫血是由于珠蛋白合成障碍所致;阵发性睡眠性血红蛋白尿是一种后天获得性造血干细胞基因突变引起的红细胞膜缺陷所致;遗传性球形红细胞增多症是由于先天性红细胞膜缺陷所致;只有冷凝集素综合征是由于机体感染某些病原体后产生自身抗体,大多为Ig型(即冷凝素),这些抗体牢固结合于红细胞上,通过激活补体,最终导致溶血。

阅读下面的文章,回答14~17题。

蜘    蛛

         (1)那是一个夏日的午后,一场不算小的雨使走廊与小园子立刻呈现出一幅肮脏不堪的样子。    

         (2)我提了一桶水,正想冲洗一下走廊,突然,在靠墙的地方,我发现了一只蜘蛛。它挺着鼓鼓的肚皮,正十分吃力地从污染着泥水的地面上朝着干燥的地方爬。看到蜘蛛,我本能地有一种厌恶的感觉,便抬起脚来,想把它踩死。

         (3)我之所以讨厌蜘蛛,是因为无论在什么地方,它都会张起网来捕捉小虫。大小蛛网上挂着小虫的残骸。无论是怎样整洁的房子,一有了蛛网,就会令人生厌,令人觉得这个屋子里的主人不勤于打扫。因此,每当我拿了扫帚,或是竹竿,清理隐藏在角落里的蛛网时,总是生气地想把它们赶尽杀绝。    

         (4)我抬起脚来,心想,这一回,这只落难的蜘蛛是死定了;而它自己似乎也知道自己正面临生死关头。它略一迟疑,便拼命地挣扎着,艰难地向墙角里爬。    

         (5)不知是一种什么意念,我抬起的脚竟没有踩下去。我看到它那样惊恐,那样吃力地爬着,顿然萌生了恻隐之心。我很快地挪开了脚,怔怔地注视着它,对于自己想弄死它的念头,反而感到不安起来。    

         (6)我从小就喜欢小动物,平时,连一只小蚂蚁都不愿随便加以伤害,何况是一只正在困难中挣扎的蜘蛛呢?

         (7)它奋斗的意志,是那样坚韧。单凭这一点,我便不该有伤害它的心理。无论如何,蜘蛛也是大自然中的一分子。虽然它不受人们的重视,可是它也应该有生存下去的权利,不是吗?它到处结网,原是和我们人类一样,只是为了经营生活,我怎能够对它心存厌恶呢?于是我找到一根竹竿,把它从地面挑起来,送到干燥的地方。它安静地爬走了。我静静地看它爬走的背影,那神态,使我心中感到无比的舒坦。    

        (8)雨过天晴,空气特别新鲜。晚霞映照着我的屋子,走廊上洒满淡淡的金黄。我怀着满心的喜悦,站在走廊上欣赏这难得的傍晚景致。

        (9)突然,我抬起头来,看到屋檐下又新结了一个网。蛛网在夕阳的光辉映照下,是那样明显:那织着多角形的网,由疏而密;有着鼓鼓肚皮的蜘蛛,坐在中央,它偶尔动弹一下,蛛网便在夕阳中微微晃动,显示出那是一个多么安逸而优美的处所。   

         (10)我凝神注视着蛛网,心中想着,不知道这只蜘蛛是不是就是我本来想要弄死的那一只?如果是,那它真是够幸运了。它原该死在我的脚下,却由于我一时的怜悯,使它得以逃生。也就因为这个缘故,我现在对于蜘蛛,反而会用欣赏的眼光来看它。其实,蜘蛛织的网,点缀在屋檐下,只要你肯用另一种眼光,从某种角度去欣赏,它将会是一幅最原始而且优美的图画呢。

         (11)不知道为什么,我以前只看到蜘蛛令我讨厌的一面,从没有发现它也有可爱的一面呢。它那不屈不挠的精神,那巧妙地织成的网,在满天晚霞的衬托下,是多么动人啊!大自然里隐藏着纯洁和恩惠,我竟然都把它给忽略了。直到这一刻,我才深深地领悟到:原来,太阳、风雨、草叶、昆虫……全都是造物者为了愉悦我们而安排和使其存在的,问题只是看我们持什么样的心情和角度去欣赏,如何去发现和爱惜它罢了。

14.请用恰当的词语描述作者对蜘蛛感情变化的过程。

   厌恶--              --理解--                

15.若将选文第(7)段中划线句改为“我不能够对它心存厌恶”表达效果有什么不同?   

 答:                                                                                                                                         

16.请阅读选文(5)-(7)段内容,用文中语句回答作者认为不该伤害它的原因。

(1)选文第(5)段中“我”看到它                                          。    

(2)选文第(7)段中“它”                                              

17.文章第(10)段中“只要你肯用另一种眼光,从某种角度去欣赏,它将会是一幅最原始而且优美的图画呢。”请你仿照下面的示例,在所提供的自然物中,选择一种,从不同的角度写出自己的看法。

     I find some of the ways in which Chinese parents show love for their children rather surprising.

Obviously there are some pretty big differences between our behaviors and theirs in this respect. Most

Chinese children seem to get whatever they want, from ice creams, sweets and toys to endless attention

from the adults around them. Is this a sort of spoiling or love? I wonder.

     Most westerners would think it is a sort of spoiling rather than love. We think love means educating

your children and bringing them up to lead an independent life. That includes learning to accept the fact

that he can't get everything he wants. As an adult, he will not always get the quite expensive car he hunts

for; she will not always manage to acquire the beautiful dress she longs for. So we try to teach our

children early to cope with the disappointment of not getting what they want.

     I find too much such kind of love for the children can actually spoil them. To my surprise, it seems that

the life of a Chinese child is rather hard. Without doubt, the child is the very center of a whole circle of

adults, but on the other hand he or she is also expected to start studying according to adults' wishes.

Many children of my son's age take piano lessons, painting classes and even English lessons. It looks as

if Chinese adults think that just playing without learning anything is a waste of time. So in this respect our

children appear spoiled, just because they are allowed to play. But without this sort of play how can

western children develop such free and rich imaginations? In fact the connection between this imagination

and the creativity is so important in the children's future life.

1. In which way do most Chinese children seem to be spoiled?

A. They can be supported by their parents

B. They can play whenever they want

C. They need not behave themselves

D. Their demand can always be satisfied

2. In the author's opinion, the life of a Chinese child is         .

A. rather hard                    

B. rather easy        

C. independent                    

D. colorful

3. The author thinks western children appear spoiled because         .

A. they can manage time by themselves  

B. they can have the freedom to play

C. they can take piano lessons          

D. they may have expensive toys

4. The best title of the passage could be         .

A. Chinese children's early education  

B. How to develop kids' imagination
