Car Accidents Declining in Walton City
According to the graph， the rise and fall of the rate of car accidents in Walton City varies with the seasons. From January to March last year it increased by 68%， from March to June it dropped by about half the previous rate; and from June to August there was a steep rise of 66.6%. After that， however， there was a steady decrease， and this makes us optimistic that car accidents are declining in Walton City.
注：1.According to the graph 如图所示，还可以说成 As can be seen from the graph
2.steep rise 陡然上升，steady decrease 缓慢下降
There are three reasons for this improvement. First， new traffic regulations have made drivers more careful， second， more people are using bicycles for transportation， and third， in the later part of the year good weather made the roads safer to drive on.
This year， major roads have been repaired and the number of public buses has been increased. Moreover， a traffic safety campaign has made all the local people more aware of the dangers of unsafe driving. So， I am confident that there will be even fewer car accidents in Walton in the future.
Film Is Giving Way to TV
(A)
The latest statistics show that the number of people attending cinemas is getting steadily smaller. At the same time， the number of television viewers is growing at almost the same rate.
Experts say that these two trends are connected in three ways. First， over the past few decades television sets have appeared in almost every home. Second， film very quickly become available on video， and can be shown on the TV screen. Third， it is becoming more expensive to make films， and so the prices of cinema seats are rising.
However， this does not mean the death of the movie industry. There will always be people who prefer to go out to see a film. This is because no matter how good a TV film or video， it can never be as entertaining as a film shown on the “big screen.”
