话题：The chart below shows the total number of Olympic medals won by twelve different countries.
The bar chart compares twelve countries in terms of the overall number of medals that they have won at the Olympic Games.
It is clear that the USA is by far the most successful Olympic medal winning nation. It is also noticeable that the figures for gold, silver and bronze medals won by any particular country tend to be fairly similar.
The USA has won a total of around 2,300 Olympic medals, including approximately 900 gold medals, 750 silver and 650 bronze. In second place on the all-time medals chart is the Soviet Union, with just over 1,000 medals. Again, the number of gold medals won by this country is slightly higher than the number of silver or bronze medals.
Only four other countries - the UK, France, Germany and Italy - have won more than 500 Olympic medals, all with similar proportions of each medal colour. Apart from the USA and the Soviet Union, China is the only other country with a noticeably higher proportion of gold medals about 200 compared to silver and bronze about 100 each
The charts below show the main reasons for study among students of different groups and the amount of support they received from employers.
The bar charts compare students of different ages in terms of why they are studying and whether they are supported by an employer.
It is clear that the proportion of students who study for career purposes is far higher among the younger age groups, while the oldest students are more likely to study for interest. Employer support is more commonly given to younger students.
Around 80% of students aged under 26 study to further their careers, whereas only 10% study purely out of interest. The gap between these two proportions narrows as students get older, and the figures for those in their forties are the same, at about 40%. Students aged over 49 overwhelmingly study for interest 70% rather than for professional reasons less than 20%.
Just over 60% of students aged under 26 are supported by their employers. By contrast, the 30-39 age group is the most self-sufficient, with only 30% being given time off and help with fees. The figures rise slightly for students in their forties and for those aged 50 or more.
