I remembered my father, the proud Marine. He made sure the first song I 7 was the Marine Hymn (美国海军陆战队队歌). He snatched off (扯下) the Christmas 8 all the decorations the rest of us had 9 and rehung them so there was 10 the same space between them. But we need not 11 those military orders, as we were not soldiers. I remembered 12 the battles he had with my mother.

Ⅱ.阅读理解(建议用时15′)A[2016·河南八市联考]The holiday season is the time of magic moments. Our hearts are waiting for something special to happen. Children dream of meeting Santa Claus and receive desirable presents. I'm sure that grandparents are waiting for their kids' and grandchildren's visit. If your holiday schedule is tightly W1 packed, then you should find at least two hours to pay a visit to P1 your grandparents.We often forget about three magic words “I love you”. Love is not a sign of weakness W2 and our grandparents deserve to hear these pleasant and healing words. Don't feel shy of showing and proving your love. Your hug and a frank smile can be the best cure for different diseases to your dear grandparents.Old people are very sensible W3 creatures. They need both physical and mental supports. Younger people should be patient enough to pay attention, hear out and don't let their grandparents feel too old, lonely and useless.S There're hundreds of ideas on how to make something good and useful for your grandparents. The best one is to bring a fresh and bushy Christmas tree to their house. Do your best todecorate W4 it with lights and ribbons. Encourage your grandparents to do it together.Unfortunately, people are like candles. The light of their eyes can die out P2 in a moment. Chances are high that their hearts will stop one day. Why don't we begin to value things before we lose them? I know that not everyone can answer this challenging question.I hope this week will bring a lot of joy to children, parents and their grandparents. Don't forget to treat grandparents with respect because they're an essential W5 part of your family.圣诞节就要到了，你的假日安排如何呢？有没有考虑这个圣诞节和你的爷爷奶奶一起过呢？读一读这篇文章，你会感悟到和爷爷奶奶一起过节的益处。

Someone was badly hurt by a bottle thrown out of a window of a building. Actually, if we look around, we will find that things of this kind are not uncommon.Cigarette ends, cans, plastic bags and bottles can be seen here and there.Needless to say, such behavior will ruin our environment and become a bad habit if we do nothing. In my opinion, every one of us should first of all make sure that we don't throw rubbish around ourselves.What is more, we should persuade others not to do so.And finally, rules should be made to stop such behavior.Only in this way can we create a better environment and live more happily.大题巧练21Unit 21Human Biology[授课提示：对应学生用书第305页]A卷一、阅读理解A(2016·浙江卷)Two things changed my life: my mother and a white plastic bike basket. I have thought long and hard about it and it's true. I would be a different person if my mom hadn't turned a silly bicycle accessory into a life lesson I carry with me today.My mother and father were united in their way of raising children, but it mostly fell to my mother to actually carry it out. Looking back, I honestly don't know how she did it. Managing the family budget must have been a very hard task, but she made it look effortless. If we complained about not having what another kid did, we'd hear something like, “I don't care what soandso got f or his birthday, you are not getting a TV in your room/a car for your birthday/a lavish sweet16 party.” We had to earn our allowance(零用钱) by doing chores around the house. I can still remember how long it took to polish the legs of our coffee table. My brothers can no doubt remember hours spent cleaning the house. Like the two little girls growing up at the White House, we made our own beds(no one left the house until that wasdone) and picked up after ourselves. We had to keep track of our belongings, and if something was lost, it was not replaced.It was summer and, one day, my mother drove me to the bike shop to get a tire fixed—and there it was in the window. White, shiny, plastic and decorated with flowers, the basket winked at me and I knew—I knew—I had to have it.“It's beautiful，” my mother said when I pointed it out to her. “What a neat basket.”I tried to hold off at first. I played it cool for a short while. But then I guess I couldn't stand it any longer: “Mom, please can I please, please get it? I'll do extra chores for as long as you say. I'll do anything, but I need that basket.I love that basket. Please, Mom. Please？”I was desperate.“You know，” she said, gently rubbing my back while we both stared at what I believed was the coolest thing ever，“If you save up you could buy this yourself.”“By the time I make enough it'll be gone！”“Maybe Roger here could hold it for you，” she smiled at Roger, the bike guy.“He can't hold it for that long, Mom. Someone else will buy it. Please, Mom, please？”“There might be another way，” she said.And so our paying plan unfolded. My mother bought the beautiful basket and put it safely in some hiding place I couldn't find. Each week I eagerly counted my growing savings increased by extra work here and there(washing the car, helping my mother make dinner, delivering or collecting things on my bike that already looked naked without the basket in front). And then, weeks later, I counted, recounted and jumped for joy. Oh, happy day! I made it! I finally had the exact amount we'd agreed upon....Days later the unthinkable happened. A neighborhood girl I'd played with millions of times appeared with the exact same basket fixed to her shiny, new bike that already had all the bells and whistles. I rode hard and fast home to tell my mother about this disaster. This horrible turn of events.And then came the lesson I've taken with me through my life：“Honey, your basket is extraspecial，” Mom said, gently wiping away my hot tears. “Your basket is special because you paid for it yourself.”语篇解读这是一篇记叙文。

Unit 21 Human BiologyⅠ.阅读理解ADear Sir，I was surprised to read your recent editorial on the question of students' part-time jobs. You appear to be making lots of general comments on the basis of just one unfortunate case (I assure you that not all young people who deliver newspapers are as foolish and dishonest as the two youths mentioned in your article, and one singlecase is not strong enough in supporting a point as evidence. I think you wouldn't disagree with me at this point)．The first point I would like to make is that there are many jobs teenagers can do which give them useful experience of the working world. They are brought into contact with a variety of people, often older, and are given experience of expressing themselves clearly and logically. Every young man will eventually be involved in social net work, and we can't expect them to act as a mature adult once they step out of school. I am thinking here of jobs such as travel guides and shop assistants. Parttime jobs are actually a kind of guiding that young people need before they play their role in real career.Another argument for school children and college students having holiday or weekend jobs is that many parents need the financial assistance. If we take, for example, a family in which the father is unemployed or perhaps a singleparent family on a low income, it seems logical and fair that a son or daughter should try to bring money into the household. And I think it's also an education to young people what family responsibility is and what one should do in terms of showing their care and love.One further thing I want to say is that a lot of jobs for the young can be fun for the people who do them and also useful to the community. Youngsters who help in schools, hospitals and with the elderly often gain a great deal of pleasure and satisfaction as well as contributing something valuable to local society. And the experience will make young people feel their value in our society so that they will be more eager to learn and more willing to offer their help.In conclusion, I would add that when I was a girl, my father said my teens were a time for books, hobbies and academic studies. Thinking back, I feel I would have learnt much more—about myself, other people and life in general—if he had allowed me to do a limited amount of real work. Certainly, when she is old enough, I shall encourage my own daughter to do so, rather than waste her time with soap operas, computer games and discos, like so many young people today. I don't mean having fun is a waste of time. I just want to point out that fun and parttime jobs could be balanced.Yours faithfully，Margaret Williams文章大意：本文是写给报社编辑的一封信。

Unit 21 Human Biology李仕才【阅读理解】There are two types of people in the world.Although they have equal degree of health and wealth and other comforts of life,one becomes happy and the other becomes unhappy.This arises from the different ways in which they consider things,persons,events and the resulting effects upon their minds.People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation,the well prepared dishes,the goodness of the wine and the fine weather.They enjoy all the cheerful things.Those who are to be unhappy think and speak only of the opposite things.Therefore,they are continually dissatisfied.By their remarks,they sour the pleasure of society,offend(hurt) many people,and make themselves disagreeable everywhere.If this turn of mind was founded in nature,such unhappy persons would be the more to be pitied.The intention of criticizing(批评) and being disliked is perhaps taken up by imitation(模仿).It grows into a habit,unknown to its possessors.The habit may be strong,but it may be cured when those who have realized its bad effects on their interests and tastes.I hope this little warning may be of service to them,and help them change this habit.Although in fact it is chiefly an act of the imagination,it has serious results in life since it brings on deep sorrow and bad luck.Those people offend many others; nobody loves them,and no one treats them with more than the most common politeness and respect.This frequently puts them in bad temper and draws them into arguments.If they aim at getting some advantages in social position or fortune,nobody wishes them success.Nor will anyone start a step or speak a word to favor their hopes.If they bring on themselves public objections,no one will defend or excuse them,and many will join to criticize their wrongdoings.These should change this bad habit and be pleased with what is pleasing,without worrying needlessly aboutthemselves and others.If they do not,it will be good for others to avoid any contact(接触) with them.Otherwise,it can be disagreeable and sometimes very inconvenient,especially when one becomes mixed up in their quarrels.1.People who are unhappy_____.A.always consider things differently from othersually are affected by the results of certain thingsually misunderstand what others think or sayD.always discover the unpleasant side of certain things2.The phrase “sour the pleasure of society〞means “_____ 〞.A.have a good taste with social lifeB.make others unhappyC.tend to scold others openlyD.enjoy the pleasure of life3.In this passage,the writer mainly____.A.describes two types of peopleughs at the unhappy peopleC.suggests the unhappy people should get rid of the habits of unhappinessD.tells people how to be happy in life参考答案： 1.D; 2.B; 3.C解析：生活中有些人拥有一样的健康、财富和生活条件,但由于考虑事情、人物、事件的角度不同,一些人感到幸福,而另一些人如此感到不幸福。

[精美语篇]It is said that sports is an important form of life. Sports can help everyone keep healthy, enrich our life and maintain our psychological health, and help us relax after a period of exhausting work. A person who often takes exercise is always full of energy. Sports can also make people look younger than they really are. What's more, it produces chances to train our intelligence. Because we think actively when we do exercise.My participation in sports tells me that sports can make us healthy both physically and psychologically.
