剑桥雅思1-3&5-7 考官范文Writing Task 1
The graph below shows the consumption of fish and some different kinds of meat in a European country between 1979 and 2004.Summarise the information by selecting and reporting the main features, and make comparisons where relevant.The graph illustrates changes in the amounts of beef, lamb, chicken and fish consumed in a particular European country between 1979 and 2004.In 1979, beef was by far the most popular of these foods, with about 225 grams consumed per person per week. Lamb and chicken were eaten in similar quantities (around 150 grams), while much less fish was consumed (just over 50 grams). However, during this 25-year period the consumption of beef and lamb fell dramatically to approximately 100 grams and 55 grams respectively. The consumption of fish also declined, but much less significantly to just below 50 grams, so although it remained the least popular food, consumption levels were the most stable.The consumption of chicken, on the other hand, showed an upward trend, overtaking that of lamb in 1980 and that of beef in 1989. By2004 it had soared to almost 250 grams per person per week.Overall, the graph shows how the consumption of chicken increased dramatically while the popularity of these other foods decreased over the period. (173 words)The charts compare the sources of electricity in Australia and France in the years1980 and 2000. Between these years, electricity production almost rising from 100 units to 170 in Australia, and from 90 to 180 units in France.In 1980, Australia used coal the main the electricity source (50 units) and the remainder was produced from natural gas, hydro power (each producing 20 units) and oil (which produced only 10 units). By 2000, coal had become the fuel for more than 75% of electricity produced and only hydro continued to be another significant source supplying approximately 20%.In contrast, France used coal as a source for only 25 units of electricity in 1980, which was matched by natural gas. The remaining 40 units were produced largely from oil and nuclear power, with hydro contributing only 5 units. But by 2000, nuclear power, which was not used at all in Australia, had developed into the main source, producing almost 75% of electricity, at 126 units, while coal and oil together produced only 50 units. Other sources were no longer significant.Overall, it is clear that by 2000 these two countries relied on different principal fuel sources: Australia relied on coal and France on nuclear power. (206 words)2. 剑二-Test1-Task1 （Table）The table below shows the consumer durables (telephone, refrigerator, etc.) owned in Britain from 1972 to 1983.Write a report for a university lecturer describing the information shown below.The chart shows that the percentage of British households with a range of consumer durables steadily increased between 1972 and 1983. The greatest increase was in telephone ownership, rising from 42% in 1972 to 77% in 1983. Next came central heating ownership, rising from 37% of households in 1972 to 64% in 1983. The percentage of households with a refrigerator rose 21% over the same period and of those with a washing machine by 14%. Households with vacuum-cleaners, televisions and dishwashers increased by 8%, 5% and 2%, respectively. In 1983, the year of their introduction, 18% of households had a video recorder.The significant social changes reflected in the statistics are that over the period the proportion of British houses with central heating rose from one to two thirds, and of those with a phone from under a half to over three-quarters. Together with the big increases in the ownership of washing machines and refrigerators, they are evidence of both rising living standards and the trend to lifestyles based on comfort and convenience. (173 words)剑二-Test3-Task1 （Table）Band 73. 剑二-Test2-Task1 （Bar chart）The chart below shows the amount of leisure time enjoyed by men and women of different employment status.Write a report for a university lecturer describing the information shown below.The chart shows the number of hours of leisure enjoyed by men and women in a typical week in 1998-9, according to gender and employment status.Among those employed full-time, men on average had fifty hours to leisure, whereas women had approximately thirty-seven hours. There were no figures given for male part-time workers, but female part-time had forty hours of leisure time, only slightly more than women in full-time employment, perhaps reflecting their work in the home.In the unemployed and retired categories, leisure time showed an increase for both sexes, as might have been expected. Here too, men enjoyed more leisure time—over eighty hours, compared with seventy hours for women, perhaps once again reflecting the fact that women spend more time working in the home than men.Lastly, housewives enjoyed approximately fifty-four hours of leisure, on average. There were no figures given for househusbands! Overall, the chart demonstrates that in the categories for which statistics on male leisure time were available, men enjoyed at least ten hours of extra leisure time. (173 words)4. 剑二-Test4-Task1 （Bar chart）The table below shows the figures for imprisonment in five countries between1930 and 1980.Write a report for a university lecturer describing the information shown below.The table shows that figures for imprisonment in the five countries mentioned indicate no overall pattern of increase of decrease. In fact there is considerable fluctuation from country to country.In Great Britain the numbers in prison have increased steadily 30,000 to 80,000 in 1980. On the other hand in Australia, and particularly in New Zealand, the numbers fell markedly from 1930 to 1940. Since then they have increased gradually, apart from in 1980 when the numbers in prison in New Zealand fell by about 30,000 from the 1970 total. Canada is the only country in which the numbers in prison have decreased over the period 1930 and 1980, although there have been fluctuations in this trend. The figures for the United States indicate the greatest number of prisoners compared to the other four countries but population size needs to be taken into account in this analysis. The prison population in the United States increased rapidly from 1970 to 1980 and this must be a worrying trend. (167 words)剑七-Test3-Task1 ( Bar chart)Band 6.51．剑一--Practice Test 3, Writing Task 1 (bar chart combined with line graph) The chart below shows the amount of money per week spent on fast foods in Britain. The graph shows the trends in consumption of fast-foods.Write a report for a university lecturer describing the information shown below.（Model answer 165 words）The chart shows that high income earners consumed considerably more fast foods than the other income groups, spending more than twice as much on hamburgers (43 pence per person per week) than on fish and chips or pizza (bothunder 20 pence). Average income earners also favoured hamburgers, spending 33 pence per person per week, followed by fish and chips at 24 pence, then pizza at 11 pence. Low income earners appear to spend less than other income groups on fast foods, though fish and chips remains their most popular fast food, followed by hamburgers and then pizza.From the graph we can see that in 1970, fish and chips were twice as popular as burgers, pizza being at that time the least popular fast food. The consumption of hamburgers and pizza has risen steadily over the 20 year period to 1990 while the consumption of fish and chips has been in decline over that same period with a slight increase in popularity since 1985.。

They had to see a doctor, so there were many people in the doctor's waiting-room. At the head of the line was an old woman. The woman did not live in London. She lived in the country. She came here to visit her daughter. She wanted to see the doctor because she got a bad cold and coughed day and night. “If I get there early, I can see the doctor quickly, ”she thought. So she was the first in the line.She sat nearest to the doctor's door. An American came into the waiting-room, and walked quickly to the doctor's door. The old woman thought he was a queue jumper. She stood up and took his arm slowly, she said, “We were all here before you. You must wait for your turn. Do you understand?”The American answered, “No, madam. You don't understand!

And it has 366 days instead of the usual 365. In a Leap Year, we have 29 days in February, while in a usual year we have only 28 days.Why do we have a Leap Year? We have a Leap Year so we can keep the calendar(日历) in step with(与…一致) the seasons. The calendar is a kind of clock for the whole year. But how long is a year? A calendar year is 365 days. However, a true year is actually 365 days, 5 hours, 48 minutes and 46 seconds long. That's the time it takes the earth to travel around the sun. So every four years we have one more day, then we have a Leap Year, and we put it at the end of February---the shortest month of a year.( ) 6. How often can we have a Leap Year?A. Every year.B. Every February.C.Every other year.D. Every four years. ( ) 7. What is a calendar? It is a kind of clock _______.A. for the whole yearB. only for Leap Year.C. for the usual yearD. for the unusual year ( ) 8.

Usually we have 365 days in a year.C. There were 29 days in February, 1992.D. The next Leap Year will be the year 2008.Life today is much easier than it was hundreds of years ago, but it has new problems. One of the biggest problems is pollution(污染). Pollution comes in many ways. We see it, smell it, drink it and even(甚至) hear it.Many years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world. The more people, the more pollution.Air pollution is still the most serious. It's bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.Many countries are making rules to fight pollution. They stop factories pouring(倒) dirty water into rivers and putting dirty smoke into the air. Except this(除此之外), we can do many more things. For example, if there are fewer people driving, there will be less pollution, too.The earth is our home. We must take care of it.根据短文内容回答下列问题。
