【題目】請閱讀下列短文，從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中，選出最佳選項(xiàng)。
A
It was unusually quiet in the emergency room on December 25. I didn't think there would be any patients, sighing about having to work on Christmas. Just then five people showed up at my desk, a pale woman and four small children.
“Are you all sick?” I asked doubtfully.
“Yes.” she said weakly and lowered her head.
But when it came to descriptions of their presenting problems, things got a little puzzling. Two of the children had headaches, but the headaches weren't accompanied by the normal body language of holding the head or trying to keep it still. Two children had earaches, but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to produce it.
Something was wrong, but I didn’t say anything but explained that it might be a little while before a doctor saw her. She responded. “Take your time; it's warm here.”
I checked the chart after the admitting clerk had finished registering the family. No address---they were homeless. The waiting room was warm.
I looked out at the family sitting close to each other by the Christmas tree. The little one was pointing at the television and the oldest one was looking at the decorations on the Christmas tree.
I went back to the nurses' station and mentioned we had a homeless family in the waiting room. The nurses, complaining about working on Christmas, turned to sympathy for a family just trying to get warm on Christmas. The team went into action, much as we do when there's a medical emergency. Only this one was a Christmas emergency.
We were all offered a free meal in the hospital cafeteria on Christmas Day, so we fetched that meal and prepared a large meal for our Christmas guests. Our team worked to meet the needs of a family who just wanted to be warm on Christmas Day.
Later, as the family walked to the door to leave, the four-year-old came running back, gave me a hug and whispered, “Thanks for being our angels today.”
（1）From the descriptions of the family's presenting problems, the writer learned that ______.
A.one of the children had a language problem
B.the mother caught a bad cold
C.they were pretending to be sick
D.they got all infectious disease
（2）The author made sure that the family were homeless by _____.
A.asking them some questions
B.listening to their descriptions of problems
C.observing their abnormal body language
D.checking their registered information
（3）What kind of person do you think the writer is?
A.Careful and warmhearted.
B.Hardworking and outgoing.
C.Serious and experienced.
D.Loving and forgiving.
（4）Which of the following is the best title of this passage?
A.Christmas Guests
B.A Homeless Family
C.Beautiful Angels
D.Christmas Emergency

【題目】閱讀下面短文，從每篇短文后所給各題的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。
A
Outside her cottage, old Mrs. Taylor was hanging out laundry on a wire line, unaware that some children were hiding in a nearby tree watching her every move. They were determined to find out if she really was a witch.（女巫）
They watched nervously as she took a broomstick(長柄掃帚）to sweep the dirt from her stone steps. But much to their disappointment, she didn't get on the broomstick and fly off. The old lady only looked up when her hen began to make sounds loudly —signaling that she had laid an egg in the nest on the top of the haystack.(干草堆).
The old lady put aside her broomstick and walked to the haystack, followed by Michael, a black cat she had rescued from a fox trap. With only three legs, it was hard for Michael to keep up with his mistress. The cat was proof for the children that only a witch would own a black cat with three legs! Crawling further along the branches, they could clearly see the haystack.
Mrs. Taylor was standing on a wooden box with the new-laid egg in one hand. Placing the egg in her pocket, she readied herself to climb down. Then, without warning, the box broke under her and she crashed to the ground. The children were in horror.
“Should we go and help her?” asked Mia.
“What if it's a trick?” replied Patrick. “She probably knows we're here. Witches know things like that!”
After thinking for a while, Julia said “Anyway, we should go and check whether she is all right.”
Approaching prudently, they could see a wound on the old lady's forehead. She had knocked her head on a stone and was unconscious.
“Go and get Dad,” Mia yelled to her brothers. “Tell him about the accident.”
The boys didn't need another excuse to leave. They ran as fast as they could for help, hoping that Mrs. Taylor would not regain consciousness and turn the girls into frogs.
Later, in the hospital, the old lady smiled her thanks. “I was so lucky that you lovely children happened to be passing when 1 fell. I must have yelled quite loudly.”
The children exchanged guilty glances, but were very pleased that she was not a witch after all!
（1）Mrs. Taylor stopped sweeping when _______.
A.her doorstep became very clean
B.she heard the hen making sounds loudly
C.she noticed the children in the tree
D.her cat Michael managed to get her attention
（2）Why was Patrick not willing to help Mrs. Taylor when she fell?
A.He thought that she could be cheating them.
B.He was afraid of the three-legged black cat.
C.He did not think that she was hurt in the fall.
D.He knew he and the others shouldn't have been in her tree.
（3）Which of the definitions is closest in meaning to the underlined word “prudently” ?
A.Slowly.
B.Hurriedly.
C.Carefully.
D.Quietly.
（4）Which of these old sayings best summaries the lesson from story?
A.Make hey while the sun shines.
B.Never judge a book by its cover.
C.A bird in the hand is worth two in the bush.
D.People in glasshouses shouldn’t throw stones.
