阅读理解。
  邻居的小孩安静,是个盲童。
  春天早晨到来以后,小区的绿地上花繁叶茂,桃花开了,月季花开了,浓郁的花香吸引着安静。
  昨天早晨,我在草地上做徒手操,安静在花树丛中__________,因为常常在花香中_________,她走得很__________,没有一点磕磕绊绊的感觉。
  终于,她在一株月季花前停了下来。
  安静是个细腻的女孩子。我们用眼睛看到浅绿深红的世界,安静用心来感受和理解。安静的面前,同样是一个层次浓淡有致的春天。我相信,她的没有视觉的世界,和我们一样丰富,甚至可能有比我们更丰富的地方。
  安静极缓极缓地伸出她的手。在花香的引导下,她的手,极其准确地伸向一朵沾满露珠的月季花。我几乎要喊出声来了,因为那朵月季花上,正停着一只蝴蝶。
  安静的手指悄然合拢,竟然拢住了那只蝴蝶。真是一个奇迹,睁着眼睛的蝴蝶被这个盲女神秘的灵性抓住。蝴蝶在安静的手指间扑腾,安静的脸上充满了惊讶。
  我静静地站在一旁,看着安静,我仿佛看见了她多姿多彩的内心世界。一瞬眼,我深深地感动着。
  安静细细地感觉着春光。许久,她张开手指,蝴蝶扑闪着翅膀飞离,安静仰起头来,在用心灵张望
  安静的心上,此刻一定划过一条美丽的弧线,蝴蝶在她八岁的人生之旅上划出了一道极其优美的飞行曲线。
  我没有惊动安静。谁都有生活的权利,谁都可以创造自我的缤纷世界。安静在这个清香袅袅的早晨,无言地告诉我这样的道理。
1.从下面的括号里选出最恰当的词填在句子相应的横线上。
  安静在花树丛中________(A.穿梭;B.穿行),因为常常在花香中________(A.流连;B.徘徊),她走得很________(A.顺畅;B.平稳),没有一点磕磕绊绊的感觉。

[ 英语 ] 阅读理解。     Sally was a student. It was going t

阅读理解。

    Sally was a student. It was going to be her mother's birthday. She wanted to buy her a present that
would be nice and useful but not expensive. A week before her mother's birthday, she went shopping
after a quick and simple lunch. When she had been looking for half an hour, she found a shop that was
selling cheap umbrellas (伞), and decided to take a black one, since her mother had lost hers the month
before.
    She thought, "You could carry that when you are wearing clothes of any color." So she decided to
buy a lovely black umbrella and took it back to school with her until her classes had finished.
    On her way back home in the train that evening, she felt hungry because she had such a small lunch
that she went along to the buffet car (餐车) for another sandwich and cup of coffee. She had left the
black umbrella above her seat in the compartment (车厢), but when she got back, it had gone! When
she had left the compartment, there had been no other passengers (乘客) in it, but now there were three.
    Sally began to cry when she saw that the umbrella was no longer there. The other passengers felt very
sorry for her and asked what the matter was. She told them that the black umbrella she had bought for
her mother was gone, and that she had to get out at the next station. After the three other passengers
heard it, they asked her for her mother's address so that they could sent the umbrella to her if someone
had taken it by mistake and brought it back after Sally had got out of the train.
    The next week, Sally heard from her mother. It said, "Thank you very much for your lovely presents,
but why did you send me three black umbrellas?"

    of any color?" [    ]
A. You can carry it when you are wearing any clothes.
B. Any color of your clothes will be all right.
C. The umbrella will be OK for your clothes in any colors.
D. You can take any clothes that you like to wear.
2. What does the story infer (推断)? [    ]
A. Her mother would write to her if she didn't receive the presents.
B. The three umbrella were sent by the girl.
C. Only four people had ever been to the compartment.
D. Nobody brought the umbrella back.
3. How many umbrellas did Sally's mother get at last?[    ]
A. No.
B. Only one.
C. Three.
D. Four.
4. The best name of the story is ______. [    ]
A. A Lucky Girl
B. The Missing Umbrella
C. A Happy Mother
D. Mother's Present
5. What does the writer want to tell us? [    ]
A. You should take care of your things when you are traveling.
B. Show your love to others, and they will bring you love.
C. Children should often come back to see their parents.
D. It's no use crying when you are in trouble.
