32、 at around 300.Then,the number shoots up over the next two hours,peaking at 450 at 8am.,After that,the number plunges for four hours,reaching 270 at 12.The period between 12 and 2 pm experiences a slight fall in the number and gets to a little below 250,the lowest point in the whole day.,In the next

33、 four hours,there is a sharp rise again.The number returns to the peak at 450 again at 7pm.After 7pm,the figure falls again,gradually to around 400 at 9pm.The number remains quite stable in the period from 9pm to 11pm,but eventually the number of people slightly declines to 380.,多曲线图的写法,根据曲线的个数分段每根曲

34、线的描述方式同单个曲线图最后加上一段文字，对所有曲线的总体变化趋势进行比较,Radio and television audiences in the UK,October-December 1992,首段,The graph shows the percentage of radio and television audiences over 4 years in the UK throughout the day from October to December 1992(总趋势).The figure reveals that before 2:00 pm there were more

35、 radio audiences,while after 2:00 pm more people turned to television.(总结),广播听众,The data indicates that radio listeners increased substantially before 8:00 am,when the percentage amounted to a peak of 27%.The percentage then declined steadily to 11%at 4:00 pm,which was followed by a slight increase

36、to 15%at 5:00 pm.However,from then on,there was again a gradual decrease to 2%until 4 am,when the percentage bottomed out.The period from 4:00 am to 6:00 am saw another slight rise to 4%in radio listeners.,电视观众,As for TV viewers,the percentage went up from 6:00 am to 8:30 am,when there was a levelin

37、g off at 8%until 10:00 am.After a slight decrease,the percentage rose sharply to 15%between 12 pm and 2pm,before it dropped slightly.The peak(45%)was reached at 8:00 pm after a massive rise from 14%since 3:00 pm.However,the period between 8:00 pm and 3:00 am saw a slump in television viewers.The per

38、centage reached the bottom of 3%at 3:00 am,when there was a slight rise afterwards.,结论,Through the line chart,we can easily draw the conclusion that before 2:00 pm,the number of radio audiences was larger than that of TV viewers.After that,more UK residents chose to watch TV instead of listening to

39、radio.Overall,in these 24 hours,the TV viewers were more than the radio audiences.,首段,The line diagram shows the proportion of people in Japan,Sweden,and USA aged 65+from 1940 and the expected proportions up to 2040.,From 1940-1990,the proportions of people aged 65+in the USA and Sweden are similar

40、and follow the same trend.In 1940 the figures were 9%and 7%respectively,rising to15%and 14%respectively in 1980,before dipping to 14%and 13%respectively in 1990.Thereafter,Americans proportion of people aged 65+leveled out and is forecast to remain at 14%until 2020,after which it is expected increas

41、e to 23%in 2040.However,Swedens proportion of people aged 65+began to rise after 1990.This increase is forecast to continue until 2010 when the proportion is estimated to be 20%.Then,there is expected to be a slight drop to 18%in 2030,followed by a steep climb to 25%in 2040.,日本,The situation in Japa

42、n differs considerably,with a fall in the percentage of people aged 65+between 1940(5%)and 1960(3%).The percentage remained steady until 1985,where upon it began to climb.This rise is projected to continue until around 2030,when the proportion of Japanese aged 65+is expected to reach 10%.Thereafter,

43、within just a few years,the proportion is forecast to rise dramatically to 25%,with a less dramatic rise to 27%in 2040.,结论,According to the graph,before the year 2030,the portion of population in Japan who aged 65+was less than that of in Sweden and America,and after that it is more than the others.

44、,多线图,The graphs below show the number of men and women in full and part-time employment in Australia between 1973 and 1993,首段,The curves reveal the percentage of men and women of different age groups in full and part-time employment in Australia between 1973 and 1993.The data relates that there were

45、 always more full-time males and less part-time males than their female counterparts.,The graphs for full-time males show that there were always more full-time males in 1973 than in 1993.In 1973 the percentage of full-time males increased massively before age 25,when the percentage leveled off at 90

46、%-95%until age 55,which was then followed by a dramatic decrease.The graph for 1993 shared the same tendency,while the percentage began to plummet at the age of 45,ten years earlier than in 1973.,As for full-time females,before age 25 there were more women participating in full-time employment in 19

47、73,while after that age 1993 saw more women.In 1973,the percentage was 47%at age 15 and soon reached a peak of 55%at age 20,which was followed by a dramatic drop until age 25.The figure continued to decline to 28%until age 30,when there was a gradual increase afterwards.However,after age 45,full-tim

48、e females again declined.A similar trend was seen in 1993.Nevertheless,at age 15,only 20%of females participated in full-time employment in 1993,27%less than in 1973.,As to part-time employment,in 1993 both males and females outnumbered their counterparts in 1973 by 10-20%,which was obviously distin

49、ct with full-time employment.For males,in 1993,the percentage slumped from 23%at age 15 to 8%at age 25,which was followed by a very small decrease until age 40,when there was a gradual rise afterwards.Then the percentage dropped again after age 60.The difference between part-time males in 1973 and 1

50、993 was in 1973 after age 35 the percentage did not decline until age 65.For females,in 1993,the percentage slumped from 30%at age 15 to 20%at age 20,and then remained stable until age 25,which was followed by a massive rise to 30%at age 35,when the figure dropped continuously afterwards.,In conclus
