课时分层作业(七)Ⅰ.阅读理解AWhile most high school students spend most of their time worrying about who likes who，and different relationships between their classmates，I choose to focus on my school lessons and sports.When I was young，my mother encouraged me to develop and keep friendship with boys in order to build strong relationships.But she told me not to risk a good friendship with a boy with the title of boyfriends.It's indeed a wise choice to stay friends with those of the opposite sex(异性)．In my opinion，even though some high school relationships might continue after graduation，the probability of them lasting much longer is so slim(微小的)that there really is not a point to it.Firstly you have to think about such a question－whether it is possible to hurt both of you，or even hurt both of your future husbands or wives.My second point is that you still can date(约会)if you hope marriage could possibly follow.Except this，there really is not any other reason for dating.Some students desire relationships for a chance to be romantic.While these are nice to have，there are many more important things at this point in our lives.The titles of boyfriend and girlfriend put too much stress(重点) on a relationship between high school students.Just staying as common friends may be the best choice for us.I strongly advise we should deal with it in a proper way and follow our teachers' advice if necessary.1．The author writes this passage probably for ________to read.A．high school studentsB．school teachersC．parents and teachersD．married couplesA[细节理解题。

课时分层作业(十三) Section Ⅰ[高考题型练习提能力]Ⅰ.阅读理解ADenmark is one of the happiest nations on earth with some of the best quality of life.You don't need statistics to understand theDane's happy lot.Walk around any Danish town and you'llexperience some of the most harmonious civic spacesanywhere.Their intimate scales and perfect transportsystems combine the rich history and bold modern linesof the built environment to delight the eye，and thelocals' manners and sense of humor is refreshing.Denmark's capital Copenhagen is a remarkable city with well­preserved medieval streets，renowned art galleries，Michelin­starred restaurants and a healthy business center.Finding something to do is never a problem and if all else fails，just admiring the streets with a hotdog in hand is an enjoyable way to spend a few hours.Beyond the capital and the bigger cities，Denmark offers a mix of lively towns such as Ribe and Odense plus rural countryside，medieval churches，Renaissance castles and tidy 18th­century villages.The coastline of Denmark with its sand dunes and greenery is a sight that always attracts visitors.So，no matter what time of year you're in Denmark，you shouldn't miss out on a trip to the nearest beach.It's hard，in short，to find fault with the place.The visitor's most heartfelt complaint is usually the cost of visiting Denmark.True，it is not a cheap destination，but no more so than the UK，and which nation's public transport system would you rather use？Cheer yourself up by thinking of the country's remarkable organization and clockwork railway timetable as being financed by the extremely high taxes paid by your hosts.When viewed in this way，this first­rate destination seems like good value，and you get the fairy tales thrown in for free：the Danish royal family is genuinely loved and respected by the vast majority of its citizens，not least handsome Prince Frederik，his beautiful Australian­b orn princess­bride，Mary，and their young family.【语篇解读】本文主要介绍了世界上最幸福国家之一——丹麦。

Meanwhile, their facial expressions were then computer analysed frame by frame in order to judge how much they were smiling based on a scale of between 0 to 1.Dr Witchci said：u According to some researchers, a real smile reflects the inner state of cheerfulness or amusement.

Unit 1 Living well Learning about language课时作业第一节阅读理解（共15小题，，每小题3分，满分45分）阅读下列短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑。

AWhen I was growing up, I had an old neighbor named Doctor Gibbs. He didn’t look like ally doctor I’d ever known. He never yelled at us for playing in his yard, but was always very kind.When Doctor Gibbs wasn’t saving lives, he was planting trees. He had some interesting theories about planting trees. He believed in the principle. “No pains, no gains”. He hardly Watered his new trees, an attitude which flew in the face of conventional wisdom.Once I asked why and he told me that watering plants spoiled them because it made them grow weaker. He said you had to make things tough for the trees so that only the strongest could survive. He talked about how watering trees made them develop shallow roots and how, if they were not watered, trees would grow deep roots in search of water. So, instead of watering his trees every morning, he’d beat them with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.Doctor Gibbs died a couple of years after I left home. Every now and then, I walked by his house and looked at the trees that I’d watched him plant some 25 years ago. They were tall and strong.I planted a couple of trees myself a few years ago. Two years of attending these trees meant they grew up weak. Whenever a cold wind blew, their branches trembled. Adversity seemed to benefit Doctor Gibb’s trees in ways that comfort and ease never could. Every night before I go to bed, I check on my two sons. I often pray that their lives will be easy. But lately I’ve been thinking that it’s time to change my prayer. I know my children are going to encounter hardship. There’s always a cold wind blowing somewhere. What we need to do is to pray for deep roots, so when the rains fall and the winds blow, we won’t be torn apart.1. With the trees planted, Doctor Gibbs often _______.A. heat them to attract neighbours’ attentionB. kept watering them every morningC. talked to them to get their attentionD. paid little attention to them2. What does the underlined word “Adversity” mean in the fifth paragraph?A. Bad weatherB. Enough care or attention.C. Difficult living conditions.D. Lack of damp.3. Which prayer does the author wish for his sons?A. Have an easy life, without too much to worry about.B. Be able to stand the rain and wind in their lives.C. Have good luck, encountering less hardship in their life.D. Meet people like Dr Gibbs in the future.BSearching for airfares often seems like a game that passengers are bound to lose. Prices change from day to day, even minute to minute. Looking through multiple websites for the best deal can be a big challenge. Even when you do book, there’s no guarantee that you are going to get the best price.“You just don’t know when to make a deal. It’s not like buying anything else I can think of,” said George Hobica, founder of Airfarewatchdog. com.Harriet Levy paid $179 for a recent round—trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $ 215. A few rows back, Ellis and Dianne Traub paid $ 317 each. There were at least 12 fares on the flight, ranging from $169 to $360. There’s no reason for it, Harrison said.Fares can change significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $ 755 to $1,143 from a Friday to Saturday in late April, then fell to $ 718 on Sunday. The flight was one of a dozen the Associated Press followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It’s the most expensive time to buy.There’s no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice:Book on Tues day, Wednesday and Thursday. That’s when airlines most often offer specialsales.Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are highest eight to ten weeks and two to three weeks in advance.Make use of social media. Airlines are giving more benefits to travelers who interact with them on Twitter and Facebook. But those specials are often gone within hours.Choose the stable or the lowest? The fares of some so-called discount airlines, such as JetBlue, Air-Tran, Southwest and Frontier, are less changeable than other airlines, so you can feel more confident that the price will stay the same. But the fares aren’t always the lowest.In all, there’s no way to guarantee the best fare, but researching different airlines’ fares can be the only way to get a good deal.4. What can we infer from the first sentence of the text?A. Airlines often play games with passengers.B. Passengers are unable to search for airfares.C. It’s difficult for passengers to get the best price.D. Airfares are set in different situations.5. By using a lot of figures, the author intends to ________.A. discover the rules behind airfaresB. prove airfares can vary widelyC. guarantee passengers a low priceD. show there is standard price for every single airline6. If you want to take a flight on Christmas, which time can be the best to book a ticket?A. September 15thB. October 15thC. November 15thD. December 15th7. Passengers are advised to book flights _________.A. at the lowest price by comparing as many airlinesB. with airlines which are famous for offering discount pricesC. through two apps on smart phonesD. on some special websitesCSharing cars to work is not unusual. But what about sharing time to raise children together? In Ningbo city of Zhejiang province in East China, young mothers in the same neighborhood pooltheir children together, and share the responsibility of being parents.Spending every day together, but not families —in this coastal city of East China, three mothers are trying a new way of raising their kids, by pooling them together. Among the mothers are both office workers and housewives. They say they do so not just because of the tight schedule. Jiujiu’s mother said, “By kids pooling, we mean to create an opportunity for the kids to spend time together so that we can observe our kids, learn more about them. And then we can discuss how to better bring them up.”The three families have been doing so for two years, in school days and holidays. Their children have grown used to each other’s company. Chichi’s mother said, “My son was a bit shy. We’ve been talking him to be more active, but he hardly changed. After joining the kids pool, suddenly we found him willing to communicate with others now. When we are not there, he has to rely on himself to get along with his pals.”Generally, mothers speak highly about the pooling. The mothers describe the pooling as bringing the running water into a closed pond. It opens a window to a different world for both kids and parents. But there are moments when opinions differ. Xiaoxiao’s mother said, “Sex education for example. Kids will be curious about it when they reach a certain age. Personally I want to talk with my child about it, frankly and sincerely. But the other two moms think it better not to bring it up.” Xiaoxiao’s mother says her solution is to share some parenting guidebooks with other mothers and let them make the decision.The headmaster of the kindergarten believes such pooling activities test not only children, but also the parents. Jin Hongqing, kindergarten headmaster said, “Parents need to be tolerant and patient. They shouldn’t play the blame game when kids fight with each other. It’s better to let the kids solve the issue by themselves. What they can do as parents is to communicate.”8. All the following aspects are the benefits of kids pooling EXCEPT ________.A. It saves tim e and helps relieve mother’s burden.B. It offers better education than the kindergartens.C. It allows parents to learn more about kids.D. It allows kids to learn to share and be independent.9. Why is sex education mentioned in the passage?A. To suggest children are sometimes curious about it.B. To explain sex education is not suitable for children.C. To indicate mothers think highly of kids pooling.D. To show sometimes mothers have different opinions.10. What’s the writer’s attitude towards kids pooling?A. Unclear.B. Favorable.C. Negative.D. Doubtful.11. Which of the following can best serve as the title of the passage?A. Chinese parenting.B. Sharing cars.C. Sharing children.D. Kids pooling.DOne in five people carry a ‘smart gene’ variant(变体)linked to long lifespan, bigger forebrains and enhanced mental ability, researchers have found.'We've known for a long time that people lose cognitive(认知) abilities as they age, but now we're beginning to understand that factors like KLOTHO can give people a boost in aging. Genetic variation in KLOTHO could help us predict brain health and find ways to protect people from the diseases that happen to us as we grow old, like Alzheimer’s disease(老年痴呆症),” said senior author, Dena Dubal of University of California.The KLOTHO gene affects a protein found in the kidneys and the brain that regulates many different body processes. About one in five people carry a single copy of the varian, known as KL-VS,which boosts levels of the protein and is associated with a longer lifespan and improved heart and kidney function. A small minority, 3% of the population, has two copies, which is linked to a shorter lifespan.In the new study scientists scanned the brains of 422 men and women aged 53 and over who were also tested for the KLOTHO gene. They found that participants with a single copy of the gene variant also had a larger brain region known as RDLPFC, which is especially likely to shrink with age. Loss of neurons in this area may be one reason why older people are sometimes easily distracted and find it difficult to do more than one task at the same time.Researcher Dr Jennifer Yokoyama said, “ The brain region enhan ced by genetic variation in KLOTHO is vulnerable(脆弱的)in aging and some mental disease. In this case, bigger size means better function. It will be important to determine whether the structure increase associated with。
