In time of serious accidents, _______we know some basic things about first aid,we can save lives.

A.whether                           B.until

C.if                                     D.unless

C


解析:

if引导条件状语从句,意为“如果”,知道一些急救的基本知识是能够抢救生命的的条件,所以用if引导条件状语从句。whether引导名词性从句或让步状语从句。until意为“直到”,表示动作持续到until从句的动作开始。unless意为“如果不,除非”,与所提供的情景矛盾。

       Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.

He rode along until a strange around drew him to the present. He came to a stop and looked curiously up to the heavens. What he saw shocked him. A huge swarm of bees filled the sky like clack cloud and the buzzing mass      towards him.

With no time to waste. Andy sped off in the opposite direction, riding furiously without knowing how to escape the swarm. With a rapidly beating heart and his legs pumping furiously, he sped down the rough road. As the bees came closer, his panic increased. Andy knew that he was sensitive to bee stings(蜇). The last sting had landed him in hospital—and that was only one bee sting! He had been forced to stay in bead for two whole days. Suddenly, his father’s words came to him. “When you are in a tight situation, don’t panic. Use your brain and think your ways out of it. ”

On a nearby hill, he could see smoke waving slowly skywards form the chimney of the Nelson family home. “Bees don’t like smoke,” he thought. “They couldn’t get into the house.”Andy raced towards the Nelson house, but the bees were gaining ground. Andy knew be could not reach the house in time. He estimated that the bees would catch up with him soon.

Suddenly, out of the corner of his eyes, he spotted a small dam used by Mr. Nelson to irrigate his vegetable garden. Off his bike and into the cool water he dived, disappearing below the surface and away from the savage insects. After holding his breath for as long as he could, Andy came up for air and noticed the bees have gone. Dragging himself out of the date, he struggled up the hilly slope and rang the doorbell. Mr Nelson took his inside and rang his mother.

“You’ll really need that fishing break to help you recover,”laughed his mother with relief. “Thank goodness you didn’t panic! But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow. ”

Mom was rightIf you say thank youfor even the smallest gift or slightest show of kindnessyou’ll feel happy.

As one of the leading scholars of the positive psychology movementhe admits gratitude may be difficult to express.He advises you to begin by admitting that life is good and full of events and elements that make daily existence a wonder.Secondrecognize that the source of life’s goodness is more than just you.That source may be your moma friendpartnerchildcolleague at work or playor any combination of these.

Gratitude is always other?directednotes Emmons.You can be pleased or angry with yourself and feel guilty about doing something wrongbut you can never be grateful to or for yourself.

Expressing gratitude shouldn’t be a reactionit should be a state of mind.To feel grateful when life is a breeze and you have more than you need is easy.To feel grateful in time of crisis—angerhatred and bitterness—is easier.Alsotoo many people are aware of life’s blessings only after these are lost.The voices expressing gratitude from his studies of individuals are many.

It’s crisis and chaos—dangerdiseasedisability and death—that bring many individuals to realize just how dependent they are on others.Yet it’s the way each of us begins life and ends it.It’s too bad that so many people waste those decades in between labouring under the illusion(幻觉) they are self?sufficientsays Emmons.

To enable and embrace gratitudeEmmons encourages the readers of Thanks! to keep a gratitude diary.He even provides easy?to?follow directions on how to practise and develop gratitude.

I’m not a reader or advocate of self?help booksbut I am thankful for the reference I found in a newspaper article to the research Emmons was conducting on gratitude involving organ donors and recipients(接受者)The chance discovery led me to this book.

Mom implied that kindness seems to find its way back to the giver because life really is all about givingreceiving and repaying.So I’ll pay attention to her professional advice and sayThank youprofessor Emmons.

Think back to this time last year. What was on your mind?

Most likely, you were thinking about finals or the holidays, although in this city I’ve noticed that thinking about the holiday is a fancy way of saying how much stuff will I get.

Now reflect on your thoughts for this holiday season. Most people are still thinking about the holidays, but I say that with a grain of salt. Everybody with a functioning brain and the ability to communicate knows that this holioday season comes with a pretty large price tag: the debt of all the hardships, both domestic and foreign, that we’ve faced over the past 12months.

Let’s face it: some of us will get everything we want over the holidays. But there are others whose parents have lost their jobs or who have lost jobs themselves because of the current economic situation. As much as we try to ignore it, there is still economic unrest in the blue and gold suburb.

In this situation, we have three options. One: We ignore the situation, like we seem to do for every bad thing that happens around us, because by God, it’s the American Way! Two: We recognize that our economy is shot, feel bad about it and spend our time wishing for the good old days. Three: We recognize that our economy is shot, but instead of moping, reflect on every good thing that we have going for us. Now, which option sounds best to you?

I spent a week this summer working in and around New York City with the city’s homeless population. Or so I thought. Although a lot of the people I served were in fact homeless, a significant number of them had a job or a home or both. The truth of the importance of this situation is that they and thousands of others across the country can’t afford even the most basic things of life, even while working two jobs. Yet no one that I met complained about their hardships. Instead, they took whatever I happened to give them(which was, more often than enough, not enough) and were genuinely grateful for what they had.

Wrap your heads around that statement for a second. These people worked their butts off to stay alive with minimal results, yet were overjoyed by a flimsy(脆弱的) paper plate with donated green beans on it. Although I am ashamed to admit it( both as a girthy figure and an affluent citizen), I have taken for granted most of my meals, let alone green beans, and I know for a fact that I am not alone.

64. 1.According to the passage when people think about holidays they care much for ____.

A.where to spend their holidays

B.how to spend their holidays

C.what they can get for their holidays

D.who they should go to visit

65. 2.When the author wrote the article, the economic situation in his country ____.

A.began to go bad.

B.began to improve

C.was still serious

D.was favorable for middle class.

66. 3.The author wrote the article mainly to advise people____.

A.to be thankful in time of hardship.

B.to spend their holidays in a wise way

C.to think little about their holidays

D.to help the country to sail through the crisis

67. 4.It can be inferred from the passage that the writer is most probably ______.

A.a homeless child

B.an old professor

C.a famous scientist

D.a young student

科目:高中英语 来源:2010年延安市高二下学期期末考试英语卷 题型:阅读理解

How often one hears children wishing they were grown-ups and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.

     Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the child — things that have lost their interest for older people because they are too well-known. But a child has his parents. He is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong.

When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.

1.According to the second paragraph, the writer thinks that __.

    A. life for a child is comparatively easy

    B. a child is always loved whatever he does

    C. if much is given to a child, he must do something in return

    D. only children are interested in life

2.After a child grows up, he __.

    A. will have little time playing

    B. has to be successful in finding a job

    C. can still ask for help in time of trouble

    D. should be able to take care of himself

3. The underlined word "responsibilities" in the second paragraph means__________.

    A. duties      B. jobs       C. suggestions     D. desires

4.The main idea of the passage is _________ .

    A. life is not enjoyable since each age has some pains

    B. young men can have the greatest happiness if they work hard

C. childhood is the most enjoyable time in one's life

D. one is the happiest if he can make good use of each age in his life
