五、商業書信：索賠信
Dear Sir or Madam,

                 Subject: A Claim on 300 Sets of Personal Computers

We have received the 300 sets of Personal Computers ordered by us. But we are so disappointed to find all the cases, without a single exception, have been badly damaged.

The Beijing Commodity Inspection Bureau presented the inspection report that the said cases of computers had been violently shocked and crashed before they were unloaded here.

Now that we totally do not need the consignment, we have no choice but to inform you to return us the invoice value and the inspection charges in the total amount of 320,000 US Dollars. As soon as the claim is settled, we will return the said consignment to you immediately.

Enclosed please find the survey report No (07) 108 issued by the Beijing Commodity Inspection Bureau. We look forward to hearing from your prompt answer.

Yours sincerely,

                                                                                      Li Ming  

六、人口增長（圖表作文）
Directions: Study the following charts carefully and write an essay in which you should

　　1) describe the charts briefly;

　　2) interpret the social phenomenon reflected by them, and

As is shown in the graphs, there exists a definite link between world population and the amount of energy consumed around the globe. The fist diagram describes that from 1900 to 2050, the world population will dramatically increase from 1.6 billion to 9 billion. It is illustrated in the second bar chart that China has effectively controlled its population growth rate by staying at 7.0 percent in 2003, 4.7 percent lower than the average world rate. As is revealed in the third table, between 1900 and 2000, the amount of world energy consumed substantially rose from 0.5 billion ton coals to 23 billion ton.

The purpose of the charts is to show us that population explosion becomes a serious problem. First and foremost, population growth has put enormous pressure on world food supplies, making it extremely difficult, if not impossible, to avoid hunger and starvation on a massive scale. Furthermore, destruction of the land has also increased as the growing amount of natural vegetation removed to make room for more houses, roads and highways. Last but not least, the rise in population is accompanied by desire of people in mounting numbers for increasingly less job opportunities, and few and few natural resources to raise their living standards.
