A
It was time for Mr. Rocco to shut up shop when I hurried into the florist’s.“Now, what is it that you want?” Mr. Rocco turned to me. “I want the most beautiful flower:you have.”I replied,“And j ust how much do you have to pay for this most beautiful flower?”I held out a wet hand showing a quarter and dime.He nodded,and then showed me a plant on the counter “I can give you this one for 35 cents.”he said.“A w, gee,”I protested,“it looks like a weed!” About l 8 inches high,the plant,was in a small pot covered with faded red paper.“Now trust me, boy---I promise that tomorrow morning when you get up,you will find your most beautiful flower.”said Mr. Rocco.I knew him to be a good honest man,so I agreed to take it.
It was almost midnight when I arrived home. Morn was seriously sick and using the front bedroom.I looked in to see if she was asleep,and then quietly tiptoed in and set the plant on the table beside her bed.I wanted her to be surprised when she woke on Mother’s Day.The next morning,I dressed and hurried downstairs.The sun was shining through kitchen window as I looked into,Mom’s room. She motioned for me to come in,then glanced over at the table where the plant was.Holy mackerel! There were three big yellow trumpet-shaped blooms..It was just like Mr. Rocco said---the most beautiful flower I ever saw! When I looked at Mom,she was smiling as tears streamed down her cheeks.She held out her hand for me to come near, then pulled me close and hugged till it hurt.Then,remembering her contagious condition and that she wasn’t supposed to touch me,she quickly let me go.

Teach Your Child to Wonder
Children start out as natural scientists,instinctively(本能地)eager to investigate the world around them.Helping them enjoy science call be easy, there’s no need for a lot of scientific terms or expensive lab equipment.You only have:to share your children’s curiosity.Firstly, listen to their questions.I once visited a classroom of seven-year-olds to talk about science as a career.The children asked me "textbook questions" about schooling,salary and whether I like my job.When I finished answering,we sat facing one another in silence.Finally I said,“Now that we’ve finished with your lists, do you have questions of your own about science?”
After a long pause.a boy raised his hand,“Have your ever seen a grasshopper(蚱蜢)eat? When I try eating leaves like that,I get stomachache.Why?”
This began a series of questions that lasted nearly two hours.
Secondly, give them time to think.Studies over the past three decades have shown that,after asking a question,adults typically wait only one second or less for a response, no time for a child to think. When adults increase their “wait time” to three seconds or more,children respond with more logical,complete and creative answers.Thirdly, watch your language.Once you have a child engaged in a science discussion,don’t,jump in with “That’s right” or “Very good”.These words work well when it comes to encouraging good behavior.But in talking about science, quick praise can signal that discussion is over. Instead,keep things going by saying,“That's interesting”or “I’d never thought of it that way before,”or coming up with more questions or ideas.
Never urge a child to “Think”.It doesn’t make sense,children are always thinking, without your telling them to.What’s more,this can turn a conversation into a performance.The child will try to find the answer you want,in as few words as possible,so he will be a smaller target for your disapproval.
Lastly, show, don’t tell. Real-life impressions of nature are far more impressive than any lesson children can gain from a book or a television program.Let children look at their fingertips (指尖)through a magnifying glass,and they’ll understand why your want them to wash before dinner.Rather than saying that water evaporates(蒸发掉),set a pot of water to boil and let them watch the water level drop.
41.According to the passage,children are natural scientists,to simulate(激发)their
interest, the important things for adults to do is .
A.to let them see the world around
B.to share their children’ curiosity
C.to explain difficult phrases about science
D.to supply their children with lab devices
42.In the last sentence of the first paragraph,the word lists could best be replaced by A.any questions B.exercise items
C.questions from textbooks D.any number of questions
43.According to the passage,the children call answer questions in more logical,complete and creative way if adults
A.1et them respond quickly
B.wait for one or two seconds after a question
C.tell them what to think
D.are patient enough when their children answer questions
44.In which of the following paragraph(s) does the author tell us what to say to encourage children in a science discussion?
A.Second and third.B.Fourth and fifth.
C.Fifth and sixth.D.Seventh.
45.The author mentions all of the following techniques for adults to share with their children’s curiosity except that adults should
A.tell their children stories instead of reciting facts
B.offer their children the chance to see things for themselves
C.Wait at least for three seconds after a question
D.encourage their children to ask questions of their own
C
Statuses(身份,地位)are marvelous human inventions that enable us to get along with one another and to determine where we “f it”in society.As we go about our everyday lives,we mentally attempt to place people in terms of their statuses.For example,we must judge whether the person in the library is a reader or a librarian, whether the telephone caller is a friend or a salesman,whether the unfamiliar person on our property is a thief or a meter reader, and so on.
The statuses we assume(承担)often vary with the people we encounter, and change throughout life.Most of us can, at very high speed,assume the statuses that various situations require. Much of social interaction consists of identifying and selecting among appropriate statuses and allowing other people to assume their statuses in relation to us.This means that we fit our actions to those of other people,based on a constant mental process of appraisal and interpretation. Although some of us find the task more difficult than others,most of us perform it rather effortlessly.
A status has been compared to ready-made clothes. Within certain limits the buyer can choose style and fabric. But an American is not free to choose the costume(服装)of a Chinese peasant or that of a Hindu prince.We must choose from among me clothing presented by our society.Further more,our choice is limited to a size that will fit, as well as by our pocketbook(钱包).Having made a choice within these limits,we can have certain alterations(改动)made,but apart from minor adjustments. we tend to be
limited to what,the stores have on their racks.Statuses too come ready made, and the range of choice among them is limited.
46.In the first paragraph the writer tells us that statuses can help us
A.determine whether a person is fit for a certain job
B.behave appropriately in relation to other people
C.protect ourselves in unfamiliar situations
D.make friends with other people
47.According to the writer, people often assume different stat uses
A.in order to identify themselves with others
B.in order to better identify others
C.as their mental processes change
D.as the situation changes
48.The word “appraisal”(Line 5,Para.2)most probably means
A.involvement B.appreciation C.judgment D.presentation 49.In the last sentence of the second paragraph,the pronoun “it” refers to “”A.fitting our actions to those of other people appropriately
B.identification of other people’s statuses
C.selecting one’s own statuses
D.constant mental process
50.By saying that “an American is not free to choose the costume of a Chinese peasant or that of a Hindu prince”(Lines2-3,Para.3),the writer means
A.different people have different styles of clothes
B.ready-made clothes may need alterations
C.statuses come ready made just like clothes
D.our choice of statuses is limited

The school principal said that he supported Ms.Smith l00%. He said that Virginia was an excellent student who would have no problem getting into the best universities even with a C in cooking.“She won’t have any difficulty finding a great university, but she might have problems finding a husband,” he laughed.“She’d better look for a mail who likes to eat out a lot.”

第三部分
第一节阅读表达(共5小题,每小题2分,满分l0分)
阅读下面的短文,请根据短文后的要求答题(请注意问题后的字数要求)
A long car journey can be a nightmare for everyone,whether they are adults or children,passengers or drivers.The driver at least has something that he or she needs to concentrate on but for the other occupants of the car, the journey can be boring,uncomfortable,and can make you feel sick. More over, passengers who suffer during car journeys can cause stress and anxiety to the driver, who may therefore lose concentration and cause all accident.
With this problem in mind,doctors and child psychiatrists have recommended a series of things to do and not do to make these journeys less stressful.
◆Surveys suggest that a major cause of arguments on car journeys is what to listen to,and evidence shows that drivers operate better if they are listening to something of their own choice.This means that,especially when different generations are traveling,
everyone except the driver who wants to listen to music should be equipped with their own source of music or radio.
◆By far the most successful strategy, especially if there are children in the car, is to turn the journey into a fun task of some kind.For example,children can be issued with an illustrated(带有插图的) worksheet,offering them the chance to tick off things that they see---a blue motorway road sign, for example,or a particular kind of tree.
◆It is of course important to have sufficient provisions(储备物)for the trip,with water on the top of the list.However doctors are now warning parents against giving their children fast food items and fizzy(起泡的)drinks,the kind of things that cause hyperactivity and can create tension and problems.
56.What is the main idea of this passage?(No more than 10 words)
57.What makes the passengers in a long car journey feel worse than the driver according to the passage?(No more than 10 words)
58.Why should the passengers who Want to listen to music be equipped with their own source of music or radio?(No more than l5 words)
59.Please explain the underlined phrase “tick off’ in English.(No more than 5 words) 60.If you are in charge of a trip and traveling in a car with some kids,what will you do to make the journey less stressful?(No more than 20 words)
