  • 第1题:

    听力原文:W: Hi, Sam, I hate to bother you but I wonder if I could have a word with you?

    M: Sounds so serious. What's up?

    W: Well, the landlord just informed me that he's going to increase our rent by two hundred. I'm wondering how you feel about it.

    M: How do I feel about it? No way! In our tenancy agreement, it says he will have to give us a notice three months in advance if he wants to increase the rent.

    W: Yeah, that's right! It's gotta be three months later. Well, I think he realizes his rental fee is below the market rate and he must be feeling a bit ripped off when he could be charging a couple hundred extra. What do you think Sam? Should we agree to the raise or find somewhere else?

    M: Good question. I'm not sure either. The location we're at now is quite convenient. Close to the grocery and near the subway. It'll be hard to find another location like this one.

    W: I wonder whether he'll allow room for negotiation. Perhaps a hundred dollars instead of two. Maybe he might be more willing to give a bit if we speak to him right way.

    M: Well, he seems to be a nice guy to talk to. But what if he refuses? Would you go for two then?

    W: Well, I guess I would, since it'll be hard to find such a convenient location. Besides, it's close to my school and I can sleep a little later in the mornings.

    M: Ha! I figured that's what you'd be concerned about. Well, I have to give it some serious thought. I'm not sure I can afford to cough up an extra hundred a month just to make sure I can sleep in an extra 15 minutes.

    W: Didn't you get your loan recently? That'll cover what you need. Besides, if you could just stop spending so much on cafeteria snacks you'd have lots of money to spare.

    M: Yeah, but I'm thinking of getting a new laptop.

    W: Well, I tell you, there aren't a lot of apartments that are cheaper, even with this new increase.

    M: I know, so when does he want us to come back on this?

    W: He told me to let him know this weekend.

    M: Sure, by then I should be able to make up my mind.

    (20)

    A.Where they should move.

    B.How to negotiate with the landlord.

    C.How to fight the increase.

    D.Whether to accept an increase in rent or move.


    正确答案:D
    解析:预览所有选项,由landlord、rent、increase可以推测对话可能与房租的上涨有关。四个选项各不相同,因此问题可能考查对话的主题。对话一开始女士就提到房东要涨房租,问男士对此怎么看,接下来两个人一直在讨论是接受房租上涨还是搬家,故答案为D。

    题目要求程序能实现从键盘任意输入的两个大整数的乘法运算。在程序中定义了一个大整数类,在类中抽象了大整数的一些属性,如长度等,还声明了一些操作,有对大整数输入的操作和对大整数求乘积的操作等。下面来具体[分析]程序。
    第(1)空在第一个大整数的输入函数中,根据此空后面的注释我们知道,其功能是把字符转换为数字。在这里需要注意的是,从键盘输入的是字符型的一串字符,此空所在的条件判断语句是用来把这串字符中的数字找出来,接下来就是此空,要求把字符型的数字转换为整型的数字,而字符型数字与整型数字之间的ASCⅡ码值相差48。从第二个大整数的输入函数中,我们也可以很容易知道此空答案为one[j]=int(Number[i]-48)。
    第(2)空在对大整数求乘积的函数中,是一个循环的初始条件,从程序中不难看出,这个二重循环是用来实现对两个大整数求乘积的,而变量j是用来存放计算结果数组的当前下标的,根据乘法的规则,不难得出此空答案为MAXRESULTBIT-(MAXINPUTBIT-i)。
    第(3)空也在求积的二重循环中,它是在语句if(result[j]>9)为真的情况下执行的语句,如果这个条件为真,说明当前需要进位,但到底是进几位,进位后余下的数又应该是多少呢?这就是这个条件判断语句下要完成的任务,从程序中不难看出,对于到底进几位这个问题已经解决,剩下的就是对进位后余数的处理,此空的任务就是求出进位后的余数并存放到数组的当前位置。所以,此空答案为result[j]%=10。
    第(4)空在输出计算结果的函数中,从程序中可以看出,此空在_个循环中,循环的作用是输出计算结果,而计算结果存放在数组中,因此,这个循环是用来输出数组中的所有元素。因此,此空答案为result[i]。
    第(5)空是在清除计算结果的函数中,函数中只有一个循环,此空就在循环下面,计算结果存放在数组中,要清除计算结果就是把数组清零,那么此空的任务是把数组中的每个元素变成零,因此,此空答案为result[i]=0。

    Night of the Living Ants

    When an ant dies,other ants move the dead insect out of the nest.This behavior is interesting to scien-
    tists,who wonder how ants know for sure一and so soon一that another ant is dead.
    Dong-Hwan Choe,a scientist at the University of California,found that Argentine ants have a chemical
    on the outside of their bodies that signals to other ants,"I'm dead一take me away."
    But there's a twist to Choe's discovery. These ants behave a little bit like zombies(僵尸).Choe says
    that the living ants一not just the dead ones一have this death chemicals. In other words,while an ant crawls
    around,perhaps in a picnic or home,it's telling other ants that it's dead.
    What keeps ants from hauling away the living dead? Choe found that Argentine ants have two additional
    chemicals on their bodies,and these tell nearby ants something like,"Wait一I'm not dead yet."So Choe's
    research turned up two sets of chemical signals in ants:one says,"I'm dead,"the other set says,"I'm not
    dead yet."
    Other scientists have tried to figure out how ants know when another ant is dead.If an ant is knocked
    unconscious,other ants leave it alone until it wakes up.That means ants know that unmoving ants can still be
    alive.
    Choe suspects that when an Argentine ant dies,the chemical that says"Wait一I'm not dead yet"quickly
    goes away. Once that chemical is gone,only the one that says"I'm dead"is left."It's because the dead ant
    no longer smells like a living ant that it gets carried to the graveyard(墓地),not because its body releases
    new,unique chemicals after death,"said Choe.When other ants detect the"dead"chemical without the"not
    dead yet" chemical,they haul away the body. This was Choe's hypothesis(假设).
    To test his hypothesis,Choe and his team put different chemicals on Argentine ant pupae(蛹).When
    the scientists used the"I'm dead"chemical,other ants quickly hauled the treated pupae away.When the sci-
    entists used the"Wait一I'm not dead yet"chemical,other ants left the treated pupae alone.Choe believes
    this behavior shows that the" not dead yet" chemical overrides(优先于)the" dead" chemical when picked up
    by adult ants.And that when an ant dies,the"not dead yet"chemical fades away.Other nearby ants then de-
    tect the remaining"dead"chemical and remove the body from the nest.

    The passage"Night of the Living Ants"tells us about_______________.
    A:how an ant is moved out of the nest at night
    B:what an ant does at night
    C:how an ant finds its way in darkness
    D:what happens when an ant dies

    答案:D
    解析:
    第二段提到:加州大学的科学家周东环发现阿根廷蚂蚁的身体能向外释放一种化学物 质来告诉同伴:“我死了,把我挪走吧。”
    根据第五段第二句可推断出C项错误。
    倒数第二段提到:一只阿根廷蚂蚁死后,发出“等等,我还没死呢”这一信号的化学物质 立刻消失,因此选D。
    周的假设是表明“我死了”的化学物质是蚂蚁本身就有的,而非死后释放的。它和表明 “我没死”的化学物质同时存在于活着的蚂蚁身上,只不过其优先权不如表明“我没死”的化学 物质。实验结果是:当科学家用“我已死”化学物质时,蚂蚁们立刻将处理过的蛹拉走。当科 学家使用“等等,我还没死”化学物质时,其他蚂蚁并不碰这个蛹。所以,周的假设是正确的。
    本文主要讲述了蚂蚁们如何迅速准确地得知同伴死了,所以选D。 第三篇 本文介绍了在山口发现的一具躺在冰上的尸体,以及由此引发的研究和种种猜测。
