The column graph gives data on the proportions of global population in four nations in three different years, including the projection for the year 2050.
As is obvious from the illustration, China and India take up the highest share of population in all these years, while the overall figure for Japan was and will still be the lowest throughout the period.
Specifically, China took a lead in 1950, with nearly a quarter of the world population. It was followed by India, which represented around 15% of the global figure. About 8% of people in the world were from the USA, compared to a share of less than 5% from Japan. In 2002, the percentage of the Indian population rose visibly to approximately 18%, while the rest three countries—China, the USA and Japan—all witnessed a moderate decline in their ratios.
Following this trend, it is predicted that India will account for a higher global share in its population and reach nearly 20% in 2050, surpassing China and making it the most populous among the four. By contrast, the 2050 population proportions of China and Japan are expected to drop to around 15% and 2% respectively. Meanwhile, the number for the USA is likely to remain the same at 5%.

题型：Nowadays advertising aimed at children is on the rise. Some people think this has negative effects and should be banned. To what extent do you agree or disagree?
答题构思： 此次调查的话题讨论是以往数次考试通过的一条旧题,调查新闻媒体与青少年儿童的文化教育.必须提示考生们的是,本个题不仅在问广告词的优缺点,要留意题型中的aimed at children修饰语,限制了另一半是对于小孩的广告词,在探讨时要把children融合进去.
Nowadays, individuals are surrounded by all kinds of advertisements, some of which are directly aimed at children and will inevitably influence their life significantly. Therefore, the questioning against children-targeted advertising has started. However,
I personally am not convinced by the suggestion that such advertisements ought to be forbidden.
It is obvious that advertisements aimed at children can be misleading and bring potential dangers to young people. As manufacturers and companies are often profit-oriented, they have a tendency to exaggerate the merits of their goods but conceal their demerits. As a result, kids and teenagers often cannot resist the temptations and ask their parents to buy commodities that they barely need, falling into the trap of impulsive consumption. A case in point is children's toys, as a huge amount of money has been wasted on purchasing toys regardless of price or functions. Besides, children overly exposed to advertisements will develop consciousness towards brands, which may lead to comparing and competition with their peers at school.
However, it is not a wise policy to ban those advertisements completely. As one of the major benefits of advertisements is that they make contribution to the economy, those aimed at children contribute to the whole industry of children-related products. If those advertisements were to be banned, the whole industry would be seriously affected. In addition, not all of television ads contain misleading or even harmful information. Public service ads serve to educate and help young people to develop good habits and become qualified citizens. Therefore, it is not advisable to prohibit all advertising of children's products.
In conclusion, advertising targeted at children should be strictly scrutinized and regulated by authorities, whereas simply banning all ads is never a good solution.
Provided is a bar illustrating how the proportions of populations in four nations taking up of the total world population varied with projection to 2050.
From the given information, shares of three countries out of four are likely to drop except that of India which, meanwhile, in 2050 is to be the most populated one.
In 1950, china had the largest population compared to other countries with a proportion of nearly 25%, while the number of people living in India accounted for 15% of the world population. In light of prediction, figure for India is possible to increase to 20% in 2050; however, Chinese proportion is falling to 17% finally.
On the other hand, a similar downward trend could be found in the percentages of populations for remaining two nations. For USA, around 7% of world population dwelled in this country in 1950, decreasing to 5% in the rest years. Over the same period, the Japanese ratio is also going to experience a steady decline, from 4% to 2%.
