In a world where
it seems we already have too much to do, and too many things to think about, it
seems the last thing we need is something new that we have to learn.
But use cases do
solve a problem with requirements:with （71） declarative requirements it's hard to describe steps and sequences of
events.
Use cases, stated
simply, allow description of sequences of events that, taken together, lead to
a system doing something useful.As simple as this sounds,this is important.
When confronted only with a pile of requiements, it's often（72）to make sense of what the authors of the
requirements really wanted the system to do.In the preceding example, use cases
reduce the ambiguity of the requirements by specifying exactly when and under
what conditions certain behavior occurs;as such, the sequence of the behaviors can
be regarded as a requirement. Use cases are particularly well suited to capture
approaches. Although this may sound simple, the fact is that （73） requirement capture approaches, with their
emphasis on declarative requirements and "shall"
statements,completely fail to capture fail to capture the （74） of the system's behavior. Use cases are a
simple yet powerful way to express the behavior of the system in way that all
stakeholders can easily understand.
But,like
anything, use cases come with their own problems, and as useful as they
are,they can be （75）. The result is something that is as bad, if not worse, that the original
problem.Therein it's important to utilize use cases effectively without
creating a greater problem than the one you started with.

第1题：
听力原文： The most prestigious exchange in the world is the New York Stock Exchange (NYSE). The NYSE is the first type of exchange, where much of the trading is done face-to-face on a trading floor. This is also referred to as a "listed" exchange. Orders come in through brokerage firms that are members of the exchange and flow down to floor brokers who go to a specific spot on the floor where the stock trades. At this location, known as the trading post, there is a specific person known as the "specialist" whose job is to match buyers and sellers. Prices are determined by using an auction method: the current price is the highest amount any buyer is willing to pay and the lowest price at which someone is willing to sell.
28. Which is the most notable exchange in the world?
29.In the NYSE, where does the "specialist" match buyers and sellers?
30.In the NYSE, what are prices determined by?

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.Coffee originally came from_______.
A:.Brazil
B: Colombia
C:Ethiopia
D: Arabia答案：C解析：细节题。第一段第一句： In the last 500 years , nothing about people—not their clothes,ideas , or languages—has changed as much as what they eat.（在过去的500年中，没有任何关于人类的东西，如他们的衣服，观点或语言，会像他们吃的食物变化那么大）同时使用比较级和否定词表示最高级，意思恰恰就是A选项的内容。
细节题。从第一段最后两句话：London shops where chocolate drinks were served became important meeting places. Some still exist today.（在伦敦，供应巧克力饮料的店铺成为了重要的聚会地点。直到今天还存在一些这样的店铺）可以推断这里的some指的就是London shops。
细节题。第二段第三句：Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “ Potato Famine ” of 1845～1846.（爱尔兰人非常依赖土豆，在1845年到1846年期间的土豆饥荒中成千上万的爱尔兰人由于土豆欠收而挨俄）。强调the crop failed , the crop即potato。 A项没有说明土豆欠收这个关键事实；B项是starve导致的结果，并非原因;C项文章并未提及。
细节题。根据第三段倒数第二句：But it is native（本土的、当地的）to Ethiopia．句中it即指coffee，意思是咖啡最早产自埃塞俄比亚。A、B项和But it is native to Ethiopia矛盾；根据第三段最后一句：Arabs最早将咖啡制作为饮品。可以推断D是错误的。
推断题。第三段最后一句：It ( coffee ) was first made into a drink by Arabs during the 1400's.最后一段讲述这个阿拉伯传说就是为了证明阿位伯人首先发明了咖啡这种饮品，即D选项的内容。 -

判断题Currently, there are about two thirds of the world’s population living in countries where water supply falls short of consumption.A对
B错
正确答案： 对解析：
录音中指出大约one third of the world’s population生活在有“水资源压力”的国家，在这些国家“consumption exceeds 10 per cent of total supply”，也就是说水资源供不应求，因此题干表述与录音内容相一致。fall short of达不到；缺乏。
【录音原文】
Global freshwater consumption rose sixfold between 1900 and 1995—more than twice the rate of population growth. About one third of the world’s population already lives in countries considered to be “water stressed”—that is, where consumption exceeds 10 per cent of total supply. If present trends continue, two out of every three people on Earth will live in that condition by 2025. -

问答题Practice 4 The line of demarcation between the adult and the child world is drawn in many ways. For instance, many American parents may be totally divorced from the church, or entertain grave doubts about the existence of God, but they send their children to Sunday school and help them to pray. American parents struggle in a competitive world where sheer cunning and falsehood are often rewarded and respected, but they feed their children with nursery tales in which the morally good is pitted against the bad, and in the end the good inevitably is successful and the bad inevitably punished. When American parents are in serious domestic trouble, they maintain a front of sweetness and light before their children. Even if American parents suffer a major business or personal catastrophe, they feel obliged to turn to their children and say, “Honey, everything is going to be all right.” This American desire to keep the children’ s world separate from that of the adult is exemplified also by the practice of delaying transmission of the news to children when their parents have been killed in an accident. Thus, in summary, American parents face a world of reality while many of their children live in a near-ideal unreal realm where the rules of the parental world do not apply, are watered down, or are even reversed.正确答案： 【参考译文】
成人世界和儿童世界在许多方面泾渭分明。比如说,许多美国人可能从来不去教堂,或者对上帝是否存在十分怀疑,但是他们却会把孩子送到主日学校,教会他们祈祷。美国人生存的社会充满竞争,尔虞我诈才能名利双收,但是在他们教育孩子的幼儿故事里,在好人与坏人的斗争中最终却总是善有善报、恶有恶报。如果美国人出现严重的家庭危机,在孩子们面前,他们表面上却仍然是温柔可亲。即使工作、生活遭遇重大挫折,他们也认为有必要对孩子说:“宝贝儿,一切都会好起来的。”如果大人遭遇事故身亡,不会立刻把噩耗告诉孩子,这种做法也可以说明美国人希望让孩子的世界和成人的世界分离开来。因此,总的来说,美国人生活在现实的世界中,孩子则生活在一个几乎完美的天地里,这里成人世界的规则则不适用,淡化了,甚至完全相反。解析： 暂无解析 -

第23题：
问答题This is the world out of which grows the hope, for the first time in history, of a society where there will be freedom from want and freedom from fear. Our very anxiety is born of our knowledge of what is now possible for each and for all. The number of people who consult psychiatrists today is not, as is sometimes felt, a symptom of increasing mental ill health, but rather the precursor of a world in which the hope of genuine mental health will be open to everyone, a world in which no individual feels that he needs be hopelessly broken-hearted, a failure, a menace to others or a traitor to himself. But if our anxieties are actually signs of hope, why is there such a voice of discontent abroad in the land? I think this comes perhaps because our anxiety exists with accompanying recognition of the tragedy which will always be inherent in human life, however well we build our world. We may banish hunger, violence and secret police, we cannot—as we have tried to do—banish death itself.正确答案：
有史以来第一次,这个世界有望成为一个没有贫困、没有恐惧的社会。由于每个人,所有的人都知道自己的命运,我们的焦虑也就由此产生。今天这么多的人去找精神病医生咨询,并不像人们常常感到的那样说明了越来越多的人患精神病,而只是预示着这样一个世界的到来:在那里,真正精神健康的希望之门将对每个人开放。他不必因为自己失败了,给他人造成威胁了,或背叛了自己的信仰而伤心欲绝,感到无可救药了。但是如果我们的焦虑是希望的象征,为什么到处还听到这样一种不满的声音呢?我认为这可能是我们焦虑的同时没有认识到这一点,即无论我们把这个世界建设得如何好,人类生活始终摆脱不了自身的悲剧。我们可以消灭饥饿,消灭暴力,消灭秘密警察,但我们无法,虽然一直在努力,使人不死。解析：
【翻译要点】
本题值得注意的是第三句...a world in which no individual feels that he needs be hopelessly broken-hearted, a failure, a menace to others or a traitor to himself中的同位语结构。在翻译中，若分析不够，很容易造成误译。显然a failure, a menace to others or a traitor to himself应是he的同位语，进一步说明he的。一般说来，作为同位关系的两个词语应放在一起的，但由于修饰关系，也有分开的。 -
