Studies show that laughter is something that makes you feel calm or relaxed for both physical and psychological wounds though it may seem futile to laugh in the face of pain and fear.

When Dan Rather interviewed comedian Bill Cosby just one week after his son, Ennis, was killed, Cosby said, “I think it is time for me to tell people that we have to laugh. You can turn painful situations around through laughter. If you can find humor in anything, you can survive it.”

Call it a flashlight for dark times: laughter just seems to adjust attitude better than anything else. Inspirational speaker Steve Rizzo recalls a TV interview with an injured firefighter a few days after 9.11.The man had fallen more than 30 stories in one of the towers and had broken a leg. Everyone was crying, and the reporter asked, “How is it that you’ve come out of this alive?” He looked at her and without missing a beat, said, “Look, lady, I’m from New York and I’m a firefighter; that’ all you need to know.”

“Everyone laughed and though the laughter was only a couple of seconds,” says Rizzo. “Sometimes that’s all you need to catch your second breath. Laughter gives you that couple of seconds. You’re sending a message to your brain, and the message is: If you can still laugh even a little among the pain, you are going to be OK.”

Of course, there is a difference between laughing off a serious situation and laughing off the fear that results. The firefighter was doing the latter, states Rizzo, the author of Becoming a Humorous Being, and so should we. “If there is anything we have learnt from 9.11, it’s how precious life really is,” she says. “We have to send a message that our spirit won’t die. One important thing that unites us is our ability to laugh.” 

60.The writer uses the examples of the comedian and the firefighter to show       .

  A.laughter is a good way to get rid of pain and fear

  B.laughter is the best way to cure psychological wounds

  C.it is your attitude that decides whether you can survive the pain or not

  D.laughing off a serious situation is different from laughing off the fear that results

61.We can infer from the passage that Steve Rizzo is            .

  A.a reporter B.a soldier   C.a firefighter   D.a doctor

62.The underlined word futile in the first paragraph means        .

  A.hopeless       B.useless

C.careless       D.worthless  

63.From the passage, we can know that Americans are         .

  A.really inspired after 9.11           B.hardly united after 9.11

C.nearly surprised by 9.11       D.greatly hurt by 9.11

科目:高中英語 來源:2014屆河北唐山一中高三第一次調研考試英語試卷(解析版) 題型:閱讀理解

It's not a new phenomenon, but have you noticed how many nouns are being used as verbs? We all use them, often without noticing what we're doing.

    I was arranging to meet someone for dinner last week, and I said “I’ll pencil it in my diary”, but my friend said “You can ink it in”, meaning that it was a firm arrangement not a tentative one!

    Many of these new verbs are linked to new technology. An obvious example is the word fax. We all got used to sending and receiving faxes, and then soon started talking about faxing something and promising we'd fax it immediately. Then along came email and we were soon all emailing each other madly. How did we live without it? I can hardly imagine life without my daily emails.

    Email reminds me, of course, of my computer and its software, which has produced another couple of new verbs. On my computer I can bookmark those pages from the World Wide Web that I think I'll want to look at again, thus saving all the effort of remembering their addresses and calling them up from scratch. I can do the same thing on my PC, but there I don't bookmark; I favorite—coming from “favorite pages”, so the verb comes from an adjective not a noun. 

Now my children bought me a mobile phone, known simply as a mobile and I had to learn yet more new verbs. I can message someone, that is, I can leave a message for them on their phone. Or I can text them, write a few words suggesting when and where to meet, for example. How long will it be before I can mobile them, that is, phone them using my mobile? I haven’t heard that verb yet, but I’m sure I will soon. Perhaps I’ ll start using it myself!  

1.“I’ll pencil it in my diary” in the second paragraph probably means “____________”.

A. it was a firm arrangement

B. he prefers a pencil to a pen

C. the arrangement should be written as a diary

D. it was an uncertain arrangement

2.A website address can be easily found if it has been ____________.

A. favorited                          B. messaged                         C. emailed                            D. texted

3. Which of the following has not been used as a verb yet?

A. message                           B. mobile                              C. email                                 D. fax

4. The best title for this passage is____________.

A. How to use verbs

B. Development of the English language

C. Origins of verbs

D. New Verbs from Nouns
