According to /As is shown in the Table /Figure/Chart...如表格/图表中显示……2. It has increased by two times as compared with that of ...同……相比，增长了2倍。3.From the table/figures/data/results/ information above, it concluded/ shown/ estimated/ calculated/inferred that...从以上的表格/图表/数据/结果/信息中，我们/总结/预测/计算/得出……4. A has the highest sales figure in the three departments, followed by B and C.在3个部门中，A的销售额最高，其次是B和C。5.The number of students has reached 600, indicating a rise of 30%, compared to last semester.学生人数达到600人，与上个学期相比上升了30%。6.The line graph show the changes on... in some place in 2010.这个折线图显示了2010年一些地方……的变化。四、注意事项文章应包括图表所示内容，但不是全部写到;叙述调查结果时要避免重复使用百分比;最重要的是要有表明自己观点的句子。书写要规范，包括大小写、标点符号等。写作之后还要注意认真检查,改正错误。7.The table shows the changes in the number of...over the period from...to...该表格描述了在……年之……年间……数量的变化。8.It can be drawn from the chart that the proportions of A and B are going down, though the falling level of the latter is a lot lower/higher than that of the former.尽管后者的下降水平比前者低/高很多，从表中我们可以看到A和B的比例都在下降。9.The increase/decrease is more noticeable during the second half of the 6 year period.在6年期的下半年，增加/减少更为明显。10. It falls from 50% in 2012 to 30% in 2016, and then the trend reverse, finishing at 58% in 2017.从2012年的50%降至2016年的30%，然后趋势逆转，2017年达到58%。Good words and good sentences上升: increase、 grow、 go up、rise、 jump、shoot下降: fall、decrease、go down、decline、dropThe graph shows that...The number rose (again)...to...The number fell (again)... to...十二、Writing完成教材28页B部分练习题。十三、Example analysis例题解析请根据以下交通事故因素( factors)统计图表,以" Major causes of traffic accidents "为题,用英语写一篇简短的分析报告,向学校英语报投稿。注意:1.报告须逐条陈述下面 pie chart和 bar chart(柱状图)中呈现的主要内容(至少5点);2.提出你对交通安全总的看法(至少2点);3.词数:80左右,开头和结尾已给出,不计入总词数。Major causes of traffic accidents Nowadays, there are many traffic accident reports from newspapers TV news and so on. The harder we try, the happier our life will be!【答案】 Major causes of traffic accidents Nowadays there are many traffic accident reports from newspapers, TV news and so on. As a result, it's important for us to analyze the major causes. The followings are the causes. According to the pie chart, there are mainly three factors: 85% of the causes are driver factors: 5% are vehicle factors and 10% are environment factors. Among them, it's quite clear that driver factors are the key point. So another bar chart points that there are 4reasons to cause traffic accidents including speeding which is 50%, drunk driving which holds 10%, tired driving which is 20% as well as not using seat belts which is 20%. In my opinion, everyone should keep in mind that traffic safety is one of the most important things in our life. At the same time, we should try our best to obey the traffic rules. The harder we try, the happier our life will be!【解析】这是一篇图标类命题作文。注意要点齐全，不能遗漏。主要以第三人称和一般现在时来说明交通事故发生的原因；对交通安全的中的看法。写作中应适当使用连词。做到上下文联系紧密，符合逻切关系。 【点评】文章中使用了非常好的短语或句子会给文章增色。 keep in mind 记住；try one's best to do sth.尽力做某事； obey the traffic rules 遵守交通规则。So another bar chart points that there are 4 reasons to cause traffic accidents including speeding which is 50%, drunk driving which holds 10%, tired driving which is 20% as well as not using seat belts which is 20%. （定语从句） In my opinion, everyone should keep in mind that traffic safety is one of the most important things in our life.（形容词最高级） The harder we try, the happier our life will be! （比较级固定句型）还运用了and so on，in my opinion ,at the same time 等使上下文衔接的更好。 The first time of word learning is for the teacher to show the students the cards, the pronunciation, spelling and meaning of the words.

According to /As is shown in the Table /Figure/Chart...如表格/图表中显示……2. It has increased by two times as compared with that of ...同……相比，增长了2倍。3.From the table/figures/data/results/ information above, it concluded/ shown/ estimated/ calculated/inferred that...从以上的表格/图表/数据/结果/信息中，我们/总结/预测/计算/得出……4. A has the highest sales figure in the three departments, followed by B and C.在3个部门中，A的销售额最高，其次是B和C。5.The number of students has reached 600, indicating a rise of 30%, compared to last semester.学生人数达到600人，与上个学期相比上升了30%。6.The line graph show the changes on... in some place in 2010.这个折线图显示了2010年一些地方……的变化。四、注意事项文章应包括图表所示内容，但不是全部写到;叙述调查结果时要避免重复使用百分比;最重要的是要有表明自己观点的句子。书写要规范，包括大小写、标点符号等。写作之后还要注意认真检查,改正错误。7.The table shows the changes in the number of...over the period from...to...该表格描述了在……年之……年间……数量的变化。8.It can be drawn from the chart that the proportions of A and B are going down, though the falling level of the latter is a lot lower/higher than that of the former.尽管后者的下降水平比前者低/高很多，从表中我们可以看到A和B的比例都在下降。9.The increase/decrease is more noticeable during the second half of the 6 year period.在6年期的下半年，增加/减少更为明显。10.

The harder we try, the happier our life will be!【答案】 Major causes of traffic accidents Nowadays there are many traffic accident reports from newspapers, TV news and so on. As a result, it's important for us to analyze the major causes. The followings are the causes. According to the pie chart, there are mainly three factors: 85% of the causes are driver factors: 5% are vehicle factors and 10% are environment factors. Among them, it's quite clear that driver factors are the key point. So another bar chart points that there are 4reasons to cause traffic accidents including speeding which is 50%, drunk driving which holds 10%, tired driving which is 20% as well as not using seat belts which is 20%. In my opinion, everyone should keep in mind that traffic safety is one of the most important things in our life. At the same time, we should try our best to obey the traffic rules. The harder we try, the happier our life will be!【解析】这是一篇图标类命题作文。注意要点齐全，不能遗漏。主要以第三人称和一般现在时来说明交通事故发生的原因；对交通安全的中的看法。写作中应适当使用连词。做到上下文联系紧密，符合逻切关系。 【点评】文章中使用了非常好的短语或句子会给文章增色。 keep in mind 记住；try one's best to do sth.尽力做某事； obey the traffic rules 遵守交通规则。So another bar chart points that there are 4 reasons to cause traffic accidents including speeding which is 50%, drunk driving which holds 10%, tired driving which is 20% as well as not using seat belts which is 20%. （定语从句） In my opinion, everyone should keep in mind that traffic safety is one of the most important things in our life.（形容词最高级） The harder we try, the happier our life will be! （比较级固定句型）还运用了and so on，in my opinion ,at the same time 等使上下文衔接的更好。 The first time of word learning is for the teacher to show the students the cards, the pronunciation, spelling and meaning of the words.
