         To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey(猎物), meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death.

    So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier(憔悴的), it constructs a wider-meshed web using fewer strands(线). Such webs would only trap larger prey, which is more economical from the perspective of a starving spider.

    The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactively,labeled materials, it was found that 95 percent of web protein reappears in the next day' web. Most of the energy needed for web-building is used in walking over the strands as they are laid down.

Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate(无脊推动物).If web-building is interrupted, or if some of the existing strands are destroyed,the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another. 

 

64. Which of the following best expresses the main ides of the passage?

  A. Secrets of Spiders' Adaptability                      B. Importance of Webs to Spiders

  C. Secrets of the Spiders' Life                            D. Spiders' Highly Preprogrammed Brain

65.According to the passage, which of the following statements is TRUE?

   A. Mast spiders will stop conducting webs when hungry

   B. One Web-building spider usually conducts one web

   C. Web-building spiders will probably die without their webs.

   D. Web-building spiders have good eyesight.

66. A spider conducts a wider-meshed web when_

   A. it is 16 days old   B. it is getting weaker     C. it has fewer strands   D. it hunts for food

67. A spider's ability to finish an incomplete web proves that_

   A. it has a highly preprogrammed brain       B. it reuses its web protein to reproduce new silk

   C. the web is everything for a spider   D. it is able to rebuild a destroyed web

To the Editor

I have been reading your newspaper, the Hometown Gazette, for the past two years, ever since I moved to Smithville. We moved here from New York City, so I am accustomed to reading excellent newspapers such as The New York Times. In fact, we still have the Times delivered on Sundays. The entire family enjoys reading the recipes(食谱) in the magazine, as well as the Styles section.

The Times is great, but the Gazette is another story. I' ve never read an article that doesn't contain at least three or four spelling or grammatical errors. For instance, in last week's issue, you misspelled the word “secretary,” used a singular verb with a plural noun, and used “it's” as a possessive(所有格). And that was just in the lead story! In case you never went to elementary school, “it's” means “it is. ”It's not a possessive adjective!

It's a pity that this tiny little hick (乡下) town has only one newspaper, because I' d like to have an alternative to the rag you publish. I find it hard to believe your news stories. If you can' t spell correctly, how can you get your facts right?

I' ve been meaning to get this off my chest for some time. Please cancel my subscription(订阅 ).And buy yourself a dictionary.

Sincerely,

Jane Z. Jones

The beginning of a Frank Sinatra song drifted across the dance floor and I knew my dad would call out and request that, which for most people is very   36  .

       As he walked towards me to ask for the first   37  , I could see there were   38  in his eyes .I grasped the side of my chair,   39  myself up with my arms ,and grabbed the two metal sticks which keep me   40  as I stood to take his hand.

       It took all my will to   41   my own tears and inside a voice kept   42  : “Don’t fall over ,Martine.” We grabbed each other and in some way shuffled(穿梭)out a dance for the whole of the song.

       For my dad, it was a turning point. He had   43   his friends on his 70th birthday he would lead his daughter in the first dance,   44   he had done so many times before .Almost a year after the suicide bomb on the London Underground train which blew   45  both my legs above the knee ,I had managed to realize his  46   .Like so much that has happened over the last 12 months, there was something   47  about the moment.

       Today, on July 1, as I face the first anniversary of the terrorist   48  , I am preparing to leave the country for a while. I know I   49   be celebrating the fact that I am alive,   50  I do not feel able to remain in London for the event.

       Psychologically, I am a different person. I am very body conscious. When I go out I am   51   that children will make fun of me on my artificial legs. In my wheelchair I cover my lower half with a blanket   52   what remains of my body draws   53   glances.

Despite my brave claims of what I would do when I left the hospital in March ,the reality is that I will  54  be able to do many things .I thought I would be able to wear my artificial legs all day, to run ,to go out alone. But that is just not possible.

I keep asking myself,   55  does it become  normal? Is this normal now?
