Chart 1
The chart shows striking differences in the level of computer and Internet penetration in the Arab world.
The UAE and Kuwait are by far the most computerized countries, with Lebanon a distant third. The UAE has over 150 computers for every 1000 inhabitants, compared to Kuwait’s 130 and Lebanon’s 60. In contrast, countries such as Egypt, Morocco and Syria have less than 20 computers per 1000 inhabitants.
There are also great differences in Internet use and availability. The UAE has by far the highest proportion of users, with more than one-third of its population using the Internet. Kuwait and Lebanon are second and third again, with 100 users per
thousand in Kuwait and 80 in Lebanon. In some countries the number using the Internet is negligible: Saudi Arabia has less than 20 users per thousand, and there are fewer than 5 users per thousand in Syria.
One unusual feature of the graph is that Internet use does not seem to be directly related to the number of computers. In several countries (the UAE, Lebanon, Jordan and Oman), there are more Internet users per thousand people than computers. However, in other countries, such as Kuwait, Saudi Arabia and Syria, the number of Internet users is lower than the number of computers.
In summary, there are major differences between computer use and Internet use in the Arab world, but the UAE clearly leads the area in both number of computers and number of internet users per capita.
Chart 2
The pie charts show changes in American spending patterns between 1966 and 1996.
Food and cars made up the two biggest items of expenditure in both years. Together they comprised over half of household spending. Food accounted for 44% of spending in 1966, but this dropped by two thirds to 14% in 1996. However, the outlay on cars doubled, rising from 23% in 1966 to 45% in 1996.
Other areas changed significantly. Spending on eating out doubled, climbing from 7% to 14%. The proportion of salary spent on computers increased dramatically, up from 1% in 1996 to 10% in 1996. However, as computer expenditure rose, the percentage of outlay on books plunged from 6% to 1%.
Some areas remained relatively unchanged. Americans spent approximately the same amount of salary on petrol and furniture in both years.
In conclusion, increased amounts spent on cars, computers, and eating out were made up for by drops in expenditure on food and books.
Chart 3
The line graph shows the fluctuation in the number of people at a London underground station over the course of a day.
The busiest time of the day is in the morning. There is a sharp increase between 06:00 and 08:00, with 400 people using the station at 8 o’clock. After this the numbers drop quickly to less than 200 at 10 o’clock. Between 11 am and 3 pm the number rises, with a plateau of just under 300 people using the station.
In the afternoon, numbers decline, with less than 100 using the station at 4 pm. There is then a rapid rise to a peak of 380 at 6pm. After 7 pm, numbers fall significantly, with only a slight increase again at 8pm, tailing off after 9 pm.
Overall, the graph shows that the station is most crowded in the early morning and early evening periods.

1. 由于来自实验室试验的新发现和对裸露断层的实地考察以及有了更好的理
论，地震物理学在过去的十年中经历了一次革命。
2. 地震是地壳板块运动的摩擦压力超过了岩石的承受能力，造成断层线断裂时
产生的。
3. 戴维先生和他在布朗大学的同事已设计出能够将地震的巨大压力作用于岩
石样本的机器，从而让地球物理学家们可以深入地研究摩擦力。
4. 实际上，了解地震的关键不是地震从哪里开始，而是断裂是如何延伸，这与
地下摩擦力的奇特方式有很大关系的。
5. 这个认识将帮助我们了解如何减轻地震带来的危害，帮助防止人员的伤亡，
还可以使我们在将来的某一天能够探测到地震的先兆。
