18．Although most of them have no doubt ________he will win the match，I still wonder________  he has been well prepared．（　　）
A．if； thatB．that； whetherC．that； thatD．whether； if

分析 雖然他們大多數(shù)人毫無(wú)疑問(wèn)地相信他會(huì)贏得這場(chǎng)比賽，但是我仍然想知道他是否已經(jīng)做好了充足的準(zhǔn)備．

解答 答案B．
分析句子結(jié)構(gòu)可知，讓步狀語(yǔ)從句中"Although most of them have no doubt ________he will win the match"有同位語(yǔ)從句"There is no doubt that…..是毫無(wú)疑問(wèn)的"，"doubt"用于否定句中只能用連詞"that"引導(dǎo)，因此排除A和D項(xiàng)；主語(yǔ)中動(dòng)詞"wonder"后為賓語(yǔ)從句，根據(jù)語(yǔ)境可知，從句中意思應(yīng)為"是否"，用"whether/if"來(lái)引導(dǎo)，排除C項(xiàng)；因此B項(xiàng)符合語(yǔ)境，故選B．

點(diǎn)評(píng) 本題考查名詞性從句．解答此類(lèi)題目首先要讀懂句意和分析句子結(jié)構(gòu)，其次判斷是名詞性從句中的哪一種從句，然后再分析從句中的成分，如果從句中缺成分且不指代人時(shí)一般用what．

8．John Blanchard stood up from the bench，straightened his Army uniform，and studied the crowd of people making their way through Grand Central Station．He looked for the girl whose heart he knew，but whose face he didn't，the girl with the rose．
His interest in her had begun thirteen months before in a Florida library．Taking a book off the shelf he found himself intrigued[1]，not with the words of the book，but with the notes penciled in the margin．The soft handwriting reflected a thoughtful soul and insightful mind．In the front of the book，he discovered the previous owner's name，Miss Hollis Maynell．With time and effort he located her address．She lived in New York City．He wrote her a letter introducing himself and inviting her to correspond．The next day he was shipped overseas for service in World War II．
    During the next year and one month the two grew to know each other through the mail．Each letter was a seed falling on a fertile heart．A romance was starting Blanchard requested a photograph，but she refused．She felt that if he really cared，it wouldn't matter what she looked like．
When the day finally came for him to return from Europe，they scheduled their first meeting-7：00 PM at the Grand Central Station in New York．"You'll recognize me，"she wrote，"by the red rose I'll be wearing on my lapel[1]．"So at 7：00 he was in the station looking for a girl whose heart he loved，but whose face he'd never seen．
    I'll let Mr．Blanchard tell you what happened：A young woman was coming toward me，her figure long and slim．Her blonde hair lay back in curls from her delicate ears； her eyes were blue as flowers．Her lips and chin had a gentle firmness，and in her pale green suit she was like springtime come alive．I started her，entirely forgetting to notice that she was not wearing a rose．As I moved，a small，attractive smile curved her lips．"Going my way，sailor？"she murmured．
    Almost uncontrollably I made one step closer to her，and then I saw Hollis Maynell．She was standing almost directly behind the girl．A woman well past 40，she had graying hair tucked under a worn hat．She was more than plump，her thick-ankled feet thrust into low-heeled shoes．The girl in the green suit was walking quickly away．I felt as though I was split in two，so keen was my desire to follow her，and yet so deep was my longing for the woman whose spirit had truly companioned me and upheld my own．
    And there she stood．Her pale，plump face was gentle and sensible，her gray eyes had a warm and kindly twinkle．I did not hesitate．My fingers gripped the small worn blue leather copy of the book that was to identify me to her．
This would not be love，but it would be something precious，something perhaps even better than love，a friendship for which I had been and must ever be grateful．I squared my shoulders and saluted and held out the book to the woman，even though while I spoke I felt choked by the bitterness of my disappointment．"I'm Lieutenant John Blanchard，and you must be Miss Maynell．I am so glad you could meet me； may I take you to dinner？"
　　The woman's face broadened into a tolerant smile．"I don't know what this is about，son，"she answered，"but the young lady in the green suit who just went by，she begged me to wear this rose on my coat．And she said if you were to ask me out to dinner，I should go and tell you that she is waiting for you in the big restaurant across the street．She said it was some kind of test!"
    It's not difficult to understand and admire Miss Maynell's wisdom． The true nature of a heart is seen in its response to the unattractive．"Tell me whom you love，"Houssaye wrote，"And I will tell you who you are．"
55． How did John Blanchard get to know Miss Hollis Maynell？C
A． They lived in the same city．
B． They were both interested in literature．
C． John knew Hollis's name from a library book．
D． John came across Hollis in a Florida library．
56． Hollis refused to send Blanchard a photo becauseC．
A． she was only a middle-aged woman
B． she wasn't confident about her appearance
C． she thought true love is beyond appearance
D． she had never taken any photo before they knew
57． How could Blanchard recognize Hollis？A
A． She would be wearing a rose on her coat．
B． She would be holding a book in her hand．
C． She would be standing behind a young girl．
D． She would be wearing a scarf around her neck．
58． What was the real Miss Hollis Maynell like？D
A． She was a plump woman with graying hair．
B． She was a slightly fat girl，with blonde hair．
C． She was a middle-aged woman in her forties．
D． She was a young，pretty girl wearing a green suit．
59． When Blanchard went over to greet the woman，he wasB．
A． satisfied and confident            
B．disappointed but well-behaved
C． annoyed and bad-mannered         
D．shocked but inspired
60． Which of the following can be the best title for the passage？A
A．A Test of Love                        B．The Symbol of Rose
C． Love is blind                        D．Don't Judge a Book by its Cover．

Don't overcrowd （把…塞滿(mǎn)） the shot．
Don't try and put too much in a single picture．Zoom in（放大鏡頭） on its front edge or focus（56）on a key area，such as an egg yolk or a steak's pink center，but not so close （57）that a viewer won't be able to tell what it is．

1．Not all vegetables need lots of sunshine．Mark Hoffman and his wife，Guia，own a bed-and-breakfast guesthouse in rural Kempton，Illinois．They often serve their guests produce fresh from the garden．
The Hoffmans have been growing food and flowers for twenty-five years．For almost ten of those years，Mr．Hoffman has been experimenting and working with shade plantings．He says visitors to his website-greenhousebed．com-often ask how to plant in shade spaces．He said，"The bottom line here is that most plants will produce more in full sun．But if you do not have full sun，there are other options．"
For example，he grows tomatoes near oak trees．Oak trees can produce a lot of shade．But Mr．Hoffman says his tomato plants grow as long as they get five hours a day of direct sunshine，especially morning sun．Not only does this go against the traditional advice that tomatoes need six，eight，even twelve hours a day of full sun，it also shows how plants and trees roots can share nutrients and water．Mr．Hoffman also planted asparagus（蘆筍） around a tree at its drip line，the area below the outer limit of the branches．So when it rains，all the rain drips down right on the asparagus．
The Hoffmans'website includes a list of vegetables，flowers and herbs that have produced acceptably for them in partial shade．Mr．Hoffman says plants with wider leaves seem to do better in shady environments．He also found that his potatoes did better in partial shade than in full sun．
Moving them out of the sun helped control an insect problem with leaf hoppers．Mr．Hoffman does not use pesticides （農(nóng)藥）．Instead，he planted the potatoes at the drip line，especially on the east side of the tree．The potatoes get morning sun，but they are shaded during the hottest part of the day．Leaf hoppers dislike shade，and the hottest part of the day is when they do the worst of their damage．
Time of day，brightness of the sun，shadows from trees，walls and buildings，these all influence how much sunlight falls or does not fall on plants．And extension agent Curtis Swift at Colorado State University says people interested in shade planting should also remember something else．The term"shade"can describe different amounts of darkness．He says it can even mean different things in different parts of the world．

46．What's the author's purpose of writing the passageC？
A．To present a kind of eco-friendly lifestyle．
B．To recommend an approach to managing a website．
C．To show vegetables can be planted in the shade．
D．To introduce Mark Hoffman and his family．
47．What can we infer from the second paragraphC？
A．Food and flowers produce more in the shade．
B．Food growing in the shade contains more nutrients．
C．Sun can affect the production of some plants．
D．Food growing in the shade is the best choice for most plants．
48．By using asparagus as an example，the author wants to explain thatB．
A．a(chǎn)sparagus prefers to grow in the shade
B．how plants and tree roots share water
C．vegetables grow better in partial shade
D．how leaves gain sunshine under the tree
49．The underlined words"leaf hoppers"in Para.5may be a kind ofC．
A．plants         
B．pesticides         
C．insects         
D．potatoes
50．According to the passage，Curtis Swift may think thatA．
A．people should consider specific situation while planting vegetables in shade
B．some special rules related to shade plantings should be remembered
C．different parts of the world should plant different kinds of vegetables in shade
D．shade planting is influenced by different kinds of soil condition．

18．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  bodies 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 in  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 huddled （擠） by the Christmas tree．The littlest one  was watching TV．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 Christmas，turned to compassion  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．But 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 banquet （盛宴） 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．"

56．From the descriptions of the family's presenting problems the author learned thatD．
A．one of the children had a language problem
B．only one of the children had bitter earaches

19．Too much eating．Too many unhealthy foods．Too many advertisements for food．Too little activity．Different explanations are offered for America's weight problem-a problem increasingly shared by other countries．Almost one-fifth of American children and teenagers are overweight．
Schools have been urged to increase physical education，an important tool for public health．And many have．Yet now comes a study showing an increase in the number of injuries in"phys ed"class．Injuries increased one hundred fifty percent between nineteen ninety-seven and two thousand seven．
The study involved injuries treated in hospital emergency departments．Only two percent were serious．
The researchers did not try to identify the causes of the increase，but they have some theories．
Lara McKenzie from Ohio State University was the lead researcher．She says one possibility is a decrease in the number of school nurses during the period they studied．For example，a two thousand four study showed that the number of school nurses nationally failed to meet federal guidelines．Schools without a nurse on duty may be more likely to send an injured child to a hospital．
Another possible reason for more injuries is a change in the traditional idea of physical education．This"New P．E．"expands the kinds of sports that are taught．But activities that some schools offer now，like rock climbing and skateboarding，can also expand the risks，says Cheryl Richardson．She is with the National Association for Sport and Physical Education．
Also，she says not all states require P．E．teachers to be specially trained．Untrained teachers could be less likely to recognize unsafe conditions．
Cheryl Richardson also points to one of the study's findings-that injuries are often the result of contact with a person or a structure．This tells her that the teachers were not giving each student enough space to move around safely．
Six activities produced seventy percent of all injuries：running，basketball，football，volleyball，soccer and gymnastics．
The researchers say larger class sizes are another possible reason for the increase in injuries．Larger classes can mean less supervision．The National Association for Sport and Physical Education says twenty to thirty students in a P．E．class should be the limit．
（Note：Answer the questions or complete the statements in NO MORE THAN TEN WORDS）

78．Many schools deal with the problem that more children are overweight byincreasing physical education．
79．What's the result of expanding the kinds of sports taught in school？The risks of getting injured increase/expand．．
80．P．E．teachers without special training are more likely toneglect unsafe conditions．
81．After reading the passage，could you give at least two suggestions to an American school on how to reduce injuries in"phys ed"classes？Increasing the number of school nurses； avoiding high risk activities．
