The chart shows the patients' evaluation of a hospital’s three wards in four different aspects.
*how satisfied patients are with the three wards of the hospital
1） 蓝色（Holly Ward）在四个方面都是maximum；
2） 红色（Roy Ward）和绿色（Oak Ward）不相上下；
3） Quality of Treatment是四个方面的maximum，对应于waitingtime是minimum。
First, the hospital’s patients are most content with Holly Ward with the satisfaction rate ranging from 65 percent (waiting time) to 90 percent (quality of treatment). Secondly, Roy Ward outperforms Oak ward in two of the four aspects. While the advantage is marginal in terms of the waiting time: 60 percent versus 56 percent, it is however noticeable in the quality of after-treatment service, where the comparison is 71 percent to 61 percent. Likewise, Oak Ward outperforms Roy Ward in the aspects of hospital staff and quality of treatment. The difference therebetween is roughly 5 percent. In addition, in all of the three wards, the quality of treatment is the most satisfactory among the four aspects, and by contrast, the patients are most dissatisfied with the length of time of waiting.
The table and charts below show the total value of fish imports to the US and the sources of fish imports to the US in 1997, 2002 and 2007.
Total value of fish imports to the US:
2）蓝色（Canada）1997=2002>2007；红色（China）1997<2002<2007；绿色（Other exporting countries）1997>2002=2007;
3）绿色（Other exporting countries）在这三个独立年份里都是maximum, 并且在2002年和2007年时与China份额相等。
In terms of the total worth of fish imports to the US, in 2007, fish that was imported to the US was worth 10.4 billion dollars, 1.9 billion more than in 2002 and 3 billion more than in 1997.In terms of the countries from which the US imported fish, Canada and China were the two dominating sources. The years of 1997 and 2002 witnessed approximately the same share by Canada, a portion that was around one-third. Canada’s share had an obvious shrinkage to one-fifth in 2007. In 2007, roughly 40 percent of the total value of fish imports was attributed to China’s exports, and the figure was noticeably greater than that of 2002 and twice of that of 1997. In addition, all other source countries accounted for either the combined share made by Canada and China or the share of China.
The table below shows the number of people having private cars in every 1,000 people in six countries in 2009, 2010 and 2011.
1） 一路升：the US, the UK, China, Germany：China最突出（2010年的300到2011年的500），其他国家稳定升，在三年里都是minimum；
2） 升了降：France, Canada
China was most noteworthy among the countries where private car ownership kept increasing during the three-year period. In the US, the UK and Germany, the growth was steady, either 50 or 100 cars a year. In China, there was an annual increase of 100 cars between 2009 and 2010, and the number spiked to 500 in 2011. In addition, China is noticeable also because its car ownership was lower than that of any other country throughout the three years.
Every 1,000 French people owned 600, 650 and 550 cars in the three years, and the fluctuating car ownership also happened in Canada, where the number varied significantly between the years, surging [surge] from 400 to 800 and then sliding [slide] to 700. It is also notable that all of the three years witnessed that the US had the highest car ownership.
