Reading Comprehension

Directions:There are two passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices. Click on the best choice. (20 points) Passage One

One of my favorite posters says, "Life is a test. It is only a test. Had this been a real life you would have been instructed where to go and what to do." Whenever I think of this humorous bit of wisdom, it reminds me not to take my life so seriously.

When you look at life and its many challenges as a test, or series of tests, you begin to see each issue you face as an opportunity to grow, a chance to discover more about life. Whether you're being bombarded (攻击、质问) with problems, responsibilities, even insurmountable (不能克服的) difficulties, when looked at as a test, you always have a chance to succeed, in the sense of rising above that which is challenging you. If, on the other hand, you see each new issue you face as a serious battle that must be won in order to survive, you're probably in for a very rocky journey. The only time you're likely to be happy is when everything is working out just right. And we all know how often that happens.

As an experiment, see if you can apply this idea to something you are forced to deal with. Perhaps you have much pressure from your parents or you have a demanding boss. See if you can redefine the issue you face from being a "problem" to being a test. Rather than struggling with your issue, see if there is something you can learn from it. Ask yourself, "Why is this an issue in my life? What would it mean and what would be involved to rise above it? Could I possibly look at this issue any differently? Can I see it as a test of some kind?"

If you give this strategy a try you may be surprised at your changed responses. It has become far more acceptable to you to accept things as they are.

21. According to the passage, what is the author's attitude towards life?

A. He takes his life seriously.

B. He considers life as a test.

C. He knows where to go and what to do.

D. He thinks life is full of humorous wisdom.

22. When you begin to consider life as a test, you will find _______________.

A. you are bombarded with problems and responsibilities

B. the result of the test is so good that you are delighted

C. you have many opportunities to grow

D. you have to go to school to take tests everyday

23. Which of the following statements is TRUE according to the author?

A. When you look at life as a test, you have a chance to overcome problems you face.

B. When you take life seriously, you are most likely to succeed and become happy.

C. When you see each problem as a serious battle, you have more opportunities to survive.

D. When everything is working out just right, you can know how often it happens.

24. It is implied from the passage that you'd better look at life as a test when __________________.

A. you try to get the meaning of the poster

B. your parents give you much pressure

C. you are carrying out an experiment

D. you are in a rocky journey

25. Which of the following can be the best title for the passage?

A. My Favorite Poster

B. Take Life Seriously

C. Face Challenge of Life

D. Life Is Only A Test

答案:BCABD

Passage Two

Thierry Daniel Henry is a French football striker currently playing for Spanish club FC Barcelona and the French national team.

Henry was born and brought up in the tough neighborhood of Les Ulis, Essonne — a suburb of Paris —where he played for an array of local sides as a youngster and showed great promise as a goal-scorer. He was spotted by AS Monaco in 1990 and signed instantly, making his professional debut in 1994. Good form led to an international call-up in 1998, after which he signed for the Italian defending champions Juventus. He had a disappointing season playing on the wing, before joining Arsenal for £10.5 million in 1999.

It was at Arsenal that Henry made his name as a world-class footballer. Despite initially struggling in the Premiership, he emerged as Arsenal's top goal-scorer for almost every season of his tenure there. Under long-time mentor and coach Arsène Wenger, Henry became a prolific striker and Arsenal's all-time leading scorer with 226 goals in all competitions. The Frenchman won two league titles and three FA Cups with the gunners shoulder to shoulder; he was twice nominated for the FIFA World Player of the Year, was named the PFA Players' Player of the Year twice, and the Football Writers' Association Footballer of the Year three times. Henry spent his final two seasons with Arsenal as club captain, leading them to the UEFA Champions League final in 2006. In June 2007, after eight years with Arsenal, he transferred to FC Barcelona for a fee of €24 million.

Henry has enjoyed similar success with the French national squad, having won the 1998 FIFA World Cup and Euro 2000 (the Delaunay Cup). In October 2007, he surpassed Michel Platini's record to become France's top goal-scorer of all time.

Off the pitch, as a result of his own experience, Henry is an active spokesperson against racism in football.

26. When did Thierry Henry first appear in a professional football game?

A. In 1990.

B. In 1994.

C. In 1998.

D. In 1999.

27. Which position does Thierry Henry usually like to play in a football game?

A. Wing.

B. Striker.

C. Goalkeeper.

D. Captain.

28. According to the passage, the gunners (Para. 3) probably means ______.

A. The enemies of Arsenal.

B. The coaches of Arsenal.

C. The supporters of Arsenal.

D. The footballers of Arsenal.

29. Which of the following honors has Thierry Henry NEVER got?

A. The Premiership League Champion.

B. The FIFA World Cup.

C. The Delaunay Cup.

D. The France Cup.

30. According to the passage, which one is TRUE?

A. Thierry Henry is always a prolific striker from AS Monaco to FC Barcelona.

B. Juventus is where Thierry Henry's splendid football life started.

C. Arsène Wenger is not only a teacher but also a friend as to Thierry Henry.

D. Michel Platini is France's top goal-scorer of all time.

系统测试和集成测试的区别 一般的小系统区分不是很大的。 1、计划和用例编制的先后顺序 从V模型来讲,在需求阶段就要制定系统测试计划和用例,HLD的时候做集成测试计划和用例,有些公司的具体实践不一样,但是顺序肯定是先做系统测试计划用例,再做集成。 2、用例的粒度 系统测试用例相对很接近用户接受测试用例。 集成测试用例比系统测试用例更详细,而且对于接口部分要重点写,毕竟要集成各个模块或者子系统。 3、执行测试的顺序 先执行集成测试,待集成测试出的问题修复之后,(配置管理,基线化),再做系统测试。 4、用例的数量 系统测试的用例数量一般比集成测试的用例数量少,具体的数量要根据各个公司的性能基线来确定,一般写不到这个数量的测试用例还通不过审计。 系统测试这个称呼往往被用于压力测试、容量测试、性能测试、安全测试等方面。 而集成测试这个称呼往往被用于细节化的功能测试的超集——从用户需求来设计和组织较大颗粒度的功能测试。 系统测试最主要的就是功能测试,测试软件《需求规格说明书》中提到的功能是否有遗漏,是否正确的实现。做系统测试要严格按照《需求规格说明书》,以它为标准。测试方法一般都使用黑盒测试 法; 集成测试在系统测试之前,单元测试完成之后系统集成的时候进行测试。集成测试主要是针对程序内部结构进行测试,特别是对程序之间的接口进行测试。集成测试对测试人员的编写脚本能力要求比 较高。测试方法一般选用黑盒测试和白盒测试相结合。 集成测试:是在软件系统集成过程中所进行的测试,其主要目的是检查软件单位之间的借口是否正确。它根据集成测试计划,一边将模块或其他年间单位组

合成越来越大的系统,一边运行该系统,以 分析所组成的系统是否正确,各个组成部分是否合拍。集成测试的策略主要有自顶向下和自底向上两种。也可以理解为在软件设计单元、功能模块组装、集成为系统时,对应用系统的各个部件(软件单元 、功能模块接口、链接等)进行的联合测试,以决定他们能否在一起共同工作,部件可以是代码块、独立的应用、网络上的客户端或服务器端程序。 系统测试:系统测试是基于软件需求说明书的黑盒测试,是对已经集成好的软件系统进行彻底的测试,以验证软件系统的正确性和性能等满足其规约所指定的要求,检查软件的行为和输出是否正确, 并非一项简单的任务,被称为测试的“先知者问题”。因此,系统测试应该按照测试计划进行,其输入、输出和其他的动态运行行为应该与软件规约进行对比。软件系统测试的方法很多,主要有功能测试 ,性能测试,随机测试等。 通俗的讲,一个产品从研发到出厂的工程中,测试分为三个阶段:单元测试、集成测试、系统测试;单元测试:一个模块的功能及常规错误测试;集成测试:完成单元测试后,各模块联调测试;集 中在各模块的接口是否一致、各模块间的数据流和控制硫是否按照设计实现其功能、以及结果的正确性验证等等;可以使整个产品的集成测试,也可以使大模块的集成测试;系统测试:针对整个产品的 全面测试,既包含各模块的验证性测试(验证前两个阶段测试的正确性)和功能性(产品提交个用户的功能)测试,又包括对整个产品的健壮性、安全性、可维护性及各种性能参数的测试。

Nature nurtures mankind unselfishly with its rich resources. Yet, man is so carried away in his transformation of nature that he is unaware that it also has limitations and needs constant care. Now worn by the excessive demands of mankind, nature is unable to maintain the ecological balance needed. Humanity is faced with the problem of how to stop, or at least to moderate, the destruction of Mother Nature. T Man in the Realm of Nature Alexander Spirkin The text is downloaded from the website: close 1RT Human beings live in the realm of nature. They are constantly surrounded by it and interact with it. Man is constantly aware of the influence of nature in the form of the air he breathes, the water he drinks, and the food he eats. We are connected with nature by "blood" ties and we cannot live outside nature. 人在自然界 亚历山大·斯伯金 人类生活在大自然的王国里。他们时刻被大自然所包围并与之相互影响。人类呼吸的空气、喝下的水和摄入的食物,无一不令人类时刻感知到大自然的影响。我们与大自然血肉相连,离开大自然,我们将无法生存。close 2RT Man is not only a dweller in nature, he also transforms it. Humanity converts nature's wealth into the means of the cultural, historical life of society. Man has subdued and disciplined electricity and compelled it to serve the interests of society. Not only has man transferred various species of plants and animals to different climatic conditions, he has also changed the shape and climate of his environment and transformed plants and animals. 人类不仅生活在大自然之中,同时也在改变着大自然。人类把自然资源转变为各种文化,社会历史的财富。人类降服并控制了电,迫使它为人类社会的利益服务。人类不仅把各种各样的动植物转移到不同的气候环境,也改变了他生活环境的地貌和气候并使动植物因之而发生转变。close 3RT As society develops, man tends to become less dependent on nature directly, while indirectly his dependence grows.
