    15．The population of China      to many times what it was in 1949，and most of its population      farmers．（　　）
    A．have grown； areB．have grown； isC．has grown； isD．has grown； are

    分析 中国的人口已经增加到949年的很多倍，并且当时大部分人口是农民．

    解答 答案 D 考查主谓一致：population作主语时谓语动词一般用单数，象第一个空就是单数，但若前面有分数或百分数修饰时，若其后跟的是系表结构，且表语为复数，谓语动词要用复数．第二个空有most of修饰，而且表语是复数，所以be动词是复数，选D．

    点评 在英语中，句子的主语和谓语动词要保持数上的一致关系，叫主谓一致．这种关系通常要遵循下面三条原则：1．语法一致原则．句子的主语是单数形式，谓语动词要用单数形式；主语是复数形式，谓语动词用复数形式2．意义一致原则即谓语动词该用单数还是复数取决于主语所表达的内容在含义是单数意义还是复数意义．3．邻近原则谓语动词该用单数还是复数形式，取决于最邻近它的名词、代词或其它词的数．这题考查的是population作主语时谓语的用法．

    5．It was a winter morning，just a couple of weeks before Christmas．While most people were warming up their cars，Trevor，my husband，had to get up early to ride his bike four kilometers away from home to work．On arrival，he parked his bike outside the back door as he usually does．After putting in 10hours of labor，he returned to find his bike gone．
    The bike，a black Kona 18speed，was our only transport．Trevor used it to get to work，putting in 60-hour weeks to support his young family．And the bike was also used to get groceries（食品杂货），saving us from having to walk long distances from where we live．
    I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story．Shortly after that，several people in our area offered to help．One wonderful stranger even bought a bike，and then called my husband to pick it up．Once again my husband had a way to get to and from his job．It really is an honor that a complete stranger would go out of their way for someone they have never met before．
    People say that a smile can be passed from one person to another，but acts of kindness from strangers are even more so．This experience has had a spreading effect on our lives because it strengthened our faith in humanity．And it has influenced us to be more mindful of ways we，too，can share with others．No matter how big or how small，an act of kindness shows that someone cares．And the results can be everlasting．

    56．Why was the bike so important to the couple？C
    A．The man's job was bike racing．
    B．It was their only possession．
    C．They used it for work and daily life．
    D．It was a nice Kona 18speed．
    57．We can infer from the text thatD．
    A．the couple worked 60hours a week．
    B．people were busy before Christmas
    C．the stranger brought over the bike
    D．life was hard for the young family．
    58．How did people get to know the couple's problem？B
    A．From radio broadcasts．    B．From a newspaper．
    C．From TV news．             D．From a stranger．
    59．What do the couple learn from their experience？D
    A．Strangers are usually of little help．
    B．One should take care of their bike．
    C．News reports make people famous．
    D．An act of kindness can mean a lot．

    3．Once Dr．Mellinkoff invited me to join him at the hospital to discuss interesting cases with his students．The case at hand was a Guatemalan man，aged 34，who had a fever and many other medical problems．His condition was not improving，and there was not much hope he would live．
    Dr．Mellinkoff asked to see the patient．He introduced himself in Spanish and，in a very gentle voice，asked how he felt．The patient smiled and said everything was all right．Then the doctor asked if he was able to eat．The patient said that he had no desire to eat．
    "Are you getting food you like？"
    The patient said nothing．
    "Do you get the kind of food you have at home？"
    The answer was no．
    The doctor put his hand on the man's shoulder and his voice was very soft．
    "If you had food that you liked，would you eat it？"
    "Yes，yes．"the patient said．
    The change in the patient's appearance couldn't have been more obvious．Nothing was said，but it was easy to tell that a message had been sent and had also been received．
    Later，the doctor asked why the Guatemalan man wasn't getting food he could eat．One of the students said，"We all know how difficult it is to get the kitchen to make special meals．"
    "Suppose，"the doctor replied，"you felt a certain medicine was absolutely necessary but that our hospital didn't carry it，would you accept defeat or would you insist the hospital meet your request？"
    "I would probably insist，"the student said．
    "Very well，"the doctor said．"You might want to try the same method in the kitchen．It won't be easy，but I can help you．Meanwhile，let's get some food inside this man as fast as possible，and stay with it．Or he'll be killed by hunger．By the way，there must be someone among you who can speak Spanish．If we want to make real progress，we need to be able to talk with him．"
    Three weeks later，Dr．Mellinkoff told me that the Guatemalan man had left the hospital under his own power．It takes more than medicine to help sick people； you also have to talk to them and make them comfortable．
    55．The patient had no desire to eat becauseB，
    A．he was not hungry                
    B．he was not satisfied with the food
    C．he was given special meals               
    D．he was seriously ill
    56．According to the passage，we can conclude thatA．
    A．the patient was from another country．
    B．the patient's illness was caused by hunger
    C．Dr．Mellinkoff performed an operation on the patient
    D．the hospital failed to provide the right medicine for the patient
    57．Which of the following words can be used to describe Dr．Mellinkoff？D
    A．Cold   B．Curious．C．Confident．D．Considerate．
    58．What do you think Dr．Mellinkoff wanted to tell his students in this case？A
    A．Doctors should know their patients'real problems．
    B．Doctors should be able to speak foreign languages．
    C．Doctors should try to improve their medical skills．
    D．Doctors should give more medicine to patients．

     Amiya Olden remembers well the day she graduated from Denby High sch001．She handed her diploma to her mother，who read it to her．"Then when someone asked me to read it，I could remember the things she read，and I knew what I had to say，"recalled Amiya Olden．"When we would go out to restaurants with my aunts，and that，S when I really would get upset．1 would see words on the menu but I couldn，t read!"
     But don‘t feel sorry for herI She changed her life by reaching a point where shel d read enough．Two summers ago，she took charge of her life when she walked into Pro Literacy Detroit to improve her reading．Nineteen months ago，she was reading at a second-grade level；now at a fifth-grade level．

    20．Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time？When you select your career，there's whole lot more to it than assessing your skills and matching them with a particular position．If you ignore your personality，it will hurt you long-term regardless of your skills or the job's pay．There are several areas of your personality that you need to consider to help you find a good job．Here are a few of those main areas：
    1）Do you prefer working alone or with other people？
    There are isolating（使孤立） jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy．Most people are not extremes in either direction but do have a tendency that they prefer．There are also positions that are sometimes a combination of the two，which may be best for someone in the middle who adapts easily to either situation．
    2）How do you handle change？
    Most jobs these days have some elements of change to them，but some are more than others．If you need stability in your life，you may need a job where the changes don't happen so often．Other people would be bored of the same daily routine．
    3）Do you enjoy working with computers？
    I do see this as a kind of personality characteristic．There are people who are happy to spend more than 40 hours a week on a computer，while there are others who need a lot of human interaction throughout the day．Again，these are extremes and you'll likely find a lot of positions somewhere in the middle as well．
    4）What type of work environment do you enjoy？
    This can range from being in a large building with a lot of people you won't know immediately to a smaller setting where you'll get to know almost all the people there fairly quickly．
    5）How do you like to get paid？
    Some people are motivated by the pay they get，while others feel too stressed to be like that．The variety of payment designs in the sales industry is a typical example for this．
    Anyway，these are a great starting point for you．I've seen it over and over again with people that they make more money over time when they do something they love．It may take you a little longer，but making a move to do what you have a passion for can change the course of your life for the better．
    49．This passage mainly talks about the importance ofB．
    A．different jobs                                  
    B．personalities
    C．personal skills

    B．Interactive jobs make people shy easily．
    C．Extreme people tend to work with others．
    D．Almost everyone has a tendency in jobs．
    51．What is the missing word about a job search in the following chart？C
    A．Design              B．Skills                C．Cooperation        D．Hobbies

    7．Wouldn't it be great if you could just look up at the sky and read the weather forecast right away？
    Well，you CAN．The forecast is written in clouds．If you can read that writing，you can tell something about the atmosphere．With some practice，you can become a pretty good weather forecaster．Who knows，you might even do as well as meteorologists （气象学家）．
    Meteorologists use much more information than just the appearance of the clouds to make their forecast．They collect data from all over the world．Then they put it into powerful，high-speed computers．
    This does give meteorologists an advantage，because they can track weather patterns as they move from west to east across the country．
    But you have an advantage，too．You have your brains．You can look at the sky and get your data directly．A meteorologist uses a computer forecast that's several hours old to make a local forecast．
    What are you seeing when you look at a cloud？"A picture of what moisture （水气） is doing in the atmosphere，"says meteorologist Peter Leavit．There's moisture throughout the atmosphere．Most of the time you don't see it，because it's in the form of an invisible gas called water vapor．
        Sometimes，the temperature of the air gets cold enough to cause the water vapor to change to liquid water．That's called condensation，and we see it happen all the time，for example，when humid air from the shower hits the cold glass of a mirror．When enough water vapor condenses，droplets form in the air．These droplets scatter light．A cloud is seen．
    Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come．Changes in clouds show changes in the atmosphere．
    You should begin to notice patterns．Certain clouds，fol1owing each other in order，can signal an approaching storm．But don't take our word for it； see for yourself．
    53．According to the passage，ordinary people can tell the weather becauseD．
    A．they can look up at the sky                         
    B．they can read weather writings
    C．information is stored in computers              
    D．clouds signal the weather to come
    54．Your advantage in weather forecast is thatC．
    A．you can keep weather patterns in mind．
    B．you have more powerful computers at home
    C．your brain works as well as a high-speed computer
    D．meteorologists give their data to you as soon as they get them
    55．A cloud is formed whenA．
    A．there are droplets in the air                        
    B．light is scattered
    C．moisture exists in the form of invisible gas  
    D．water vapor changes to liquid water
    56．This passage mainly tells us about howD．
    A．to become a weather forecaster                   
    B．to collect data directly
    C．to be an assistant to a meteorologist             
    D．to keep an eye on the weather．

    5．People living more than three thousand meters above sea level find it difficult to raise vegetables all year long．People living in the highlands of Peru and Bolivia，for example，cannot grow vegetables outdoors during the months of May through September．It is very cold in the highlands at that time of year．If traditional farming methods are used，vegetables will not survive．
    However，there is another way to grow vegetables throughout the year in cold areas．It is a method of gardening developed by a private agency called World Neighbors．The method uses"hot houses"built below ground．A hot house is a building covered with plastic or glass in which vegetables or flowers are grown．The traditional hot house is built above ground．
    The air temperature is cold in the highlands of Peru and Bolivia during the winter．But，the winter sun is hot．So，World Neighbors advises farmers there to build hot houses below ground．The design is simple．The material does not cost much．Here is how World Neighbors says to build it：Dig a hole two and one-half meters wide and six meters long．Make it about two meters deep．Build wall with a door in one end of the hole．Dig steps from the ground down to the door．
    Now，build a wall along the top edge of the hole．Make it about one-half meters tall．Earth bricks work fine．Build two shorter walls on the ends．These will be uneven； one side will be as high as the existing wall．The other side will be at ground level．Leave a small opening in each of these sloping walls．This prevents the hot house from becoming too hot．Now，make the roof．Build a wood frame．Cover it with clear plastic．Connect it to the brick walls．
    The underground hot house we have described is large enough for two raised vegetable beds．Each is one meter wide and six meters long．Each is seeded and watered just as if it were in a garden above ground．
    The dirt walls protect the growing plants from the cold．The clear plastic roof permits the sun's heat to enter．At night，the roof should be covered with straw．This helps prevent cold air from entering．An under ground hot house this size will provide enough vegetables for one family．Groups needing more vegetables can make it bigger．

    66．If you lived in Peru，youC．
    A．should raise the special kinds of vegetables that can endure cold
    B．could not plant at all
    C．had to work out some new unusual plans
    D．would not have many vegetables to eat
    67．To our surprise，the"hot houses"invented by World Neighbors areB．
    A．covered with a transparent plastic ceiling
    B．built under ground
    C．quite small
    D．hotter than traditional ones
    68．The hot house can be kept warm by usingD．
    A．a big oven
    B．an electricity heater
    C．the heat of the earth's interior
    D．the sun shine
    69．The measure to prevent the hot house from becoming too hot is toB．
    A．make the roof sloped
    B．dig holes on the walls
    C．make the wall not vertical
    D．make the walls shorter than the ground level
    70．According to the passage，the method suggested by World Neighbors isD．
    A．new and difficult     B．uneasy to explain
    C．at trial step         D．simple and practical．
