“My lifelong pursuit is to keep all the people away from hunger.”
—Yuan Longping
我毕生的梦想就是让所有人远离饥饿。
Let’s review the text about Yuan Longping. Pay special attention to the words and phrases italicized.
As a witness to farmers’ poor harvests and even a severe shortage of food, Yuan Longping was determined to devote his life to tackling this crisis. After graduation, he realised that what farmers needed most was to boost yields in the fields. Yuan was convinced that the answer lay in the creation of hybrid rice, one characteristic of which is that it usually achieves higher output than conventional crops. However, it was no easy job. The first difficulty he needed to overcome was scientists’ general assumption that this could not be done. Through intense effort, Yuan managed to generate this incredible crop. It is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated from Yuan’s hybrid strains. His innovation has enabled Chinese farmers to considerably expand their output and helped feed the world. Unwilling to retire early to a life of leisure and unconcerned about celebrity or fortune, Yuan continued to turn one vision after another into realities. Most importantly, deep down, he always thought himself a farmer.

Grandma has been complaining about the vegetables sold in the supermarket, which have been grown using chemical fertilisers. To her, that they look beautiful on the outside is obvious. However, what she is unhappy about is the lower nutritional value and reduced flavour. Now that both of my grandparents have retired from their jobs in the city, how they are going to spend their retirement is an important decision for them. Whether they can live a healthy life is the first thing they are considering. So they have made up their minds to move to the countryside, where they can live a green life.
