     Two graduates from Cambridge University in the United Kingdom found themselves about to

graduate, yet with loans (贷款) to pay off. The pair decided to begin a strange, year-long project

to battle their debt. The men, Ross Harper and Ed Moyse, set up the site BuyMyFace.co.uk. last

October as a way to get rid of the $80,000 they shared as student loans. The idea behind the project

was to earn money by selling their faces as advertising space every day for a year. Each day, they

advertise a different business on their site by painting the brand's logo (商标) or name on their faces

and including a link to the company's site. After they paint their faces and publish them on the site,

Harper and Moyse go out to highly populated areas such as music festivals and theme parks to

maximize their faces' exposure.

     At this time, Harper and Moyse have advertised their faces for over four months without skipping

a day and they're more than halfway to their goal. Though they first started charging a minimum of

about USD $1.60 per company, the prices have risen as their popularity increased. For advertising

space during the remainder of April, they range between USD $250 and $750.

     Terri L. Rittenburg, associate professor of marketing at the University of Wyoming, said she had

heard of people tattooing (纹身) logos on themselves before, but this idea is much better. According

to her, at first the idea would be new and novel and attract attention, but she is unsure how long it

would last.

     At least for now, companies that have bought Harper and Moyse's faces have written positive

comments on the pair's website. "We had a three percent increase in website traffic (流量) on the

very day and for two days more afterwards," said an alcoholic beverage company.

1. Which of the following was most possibly taken from the website BuyMyFace.co.uk.?

A.  

B.     

C.   

D.

2. At BuyMyFace.co.uk, you can _____ of the company being advertised for.

A. click to enter the website

B. download product pictures

C. get in touch with the staff

D. read a brief introduction

3. Harper and Moyse go to highly populated areas to _____.

A. have fun  

B. make friends

C. show their faces  

D. find new customers

4. We can infer from the article that the two men _____.

A. must have earned more than $40,000

B. aren't getting on well with their project

C. may close their site next month

D. always work hard except on holidays

5. The men's idea of advertising has proved to work because _____.

A. many people visit their website

B. their faces have become well-known

C. their customers get more attention

D. an expert has highly praised them

填空题

短周期元素A、B、C、D、E原子序数依次增大。A是周期表中原子半径最小的元素,B是形成化合物种类最多的元素,C是自然界含量最多的元素,D是同周期中金属性最强的元素,E的负一价离子与C的某种氢化物W分子含有相同的电子数。

(1)A、C、D形成的化合物中含有的化学键类型为        ;W的电子式        

(2)已知:①2E → E-E;=-a kJ·mol-1 ② 2A → A-A;=-b kJ·mol-1

③E+A → A-E;=-c kJ·mol-1

写出298K时,A2与E2反应的热化学方程式                                   

(3)在某温度下、容积均为2L的三个密闭容器中,按不同方式投入反应物,保持恒温恒容,使之发生反应:2A2(g)+BC(g)X(g);=-a KJ·mol-1(a>0,X为A、B、C三种元素组成的一种化合物)。初始投料与各容器达到平衡时的有关数据如下:
