Remember to look up at the stars and not down at your feet.
Work gives your meaning and purpose and life is empty without it.
If you are lucky enough to find love, remember it is there and don’t throw it away.
However difficult life may seem, there is always something you can do and succeed at.
It matters that you don’t just give up.
Where is life, there is hope.

Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace which are widely regarded as the most prestigious awards available in their respective fields.

Problems Solutions
The extracts failed to produce any promising results.
Tu and her team could not produce enough qinghaosu extract because research resources were limited.
Tu and her team did not have sufficient safety data to start trials on patients.
Tu Youyou referred to the ancient books of TCM again, redesigned the experiments and tried extracting the qinghao herb at a low temperature in order not to damage its effective part.
Tu Youyou and her team managed to find solutions to the problem, e.g. using household water containers instead of research equipment.
Tu Youyou and her team volunteered to test the qinghao extract on themselves.

Sample
My Hero
Speaking of heroes, it is not difficult to think of great heroes in history. As for me, I have a hero in my heart who fights with the virus--academician Zhong Nanshan.（开门见山，谁是你的英雄。）
Firstly, in this fight against the virus, academician Zhong Nanshan faces the virus bravely at the age of 84. Secondly, He leads us on the perfect and right road with his calmness and knowledge. What’s more, it is he who saved lots of patients.（分点阐述原因—英雄的成就和精神。）
I am moved by his spirit of devotion. He is a good example for me to follow. I will study hard and return for the society. He is my real hero in my heart.（总结）
