Let’s learn some beautiful sentences!
1. As a boy he was educated in many schools and was given the nickname, “ the student who asks questions”.
= When he was a boy, Yuan Longping studied in many schools and was nicknamed “the student who asks questions”.
本句为一个简单句。and连接两个并列的被动结构；the student who asks questions为the nickname的同位语；who asks questions为定语从句，修饰先行词the student。
2. He thought that the key to feeding
people was to have more rice and to produce it more quickly.
= He believed that having more rice and producing it more quickly was the most important thing to feed people.
本句是一个复合句。that the key ... it more quickly是宾语从句；宾语从句中两个并列的动词不定式短语to have more rice和to produce it more quickly作表语。
the key to feeding people类似用法的名词还有:
answer, solution, journey, trip, tour, visit, way, entrance, flight等。

disagreement between the company

3. He thought there was only one way to do this — by crossing different species of rice plant, and then he could produce a new plant which could give a higher yield than either of the original plants.
= Yuan Longping thought that only by crossing different species of rice plant could people have more rice and produce it more quickly, and then he could develop a new type of plant whose yield is greater than either of the original plants.
本句为and连接的两个并列分句。前面的分句为主从复合句，there was only one way to do this为省略引导词that的宾语从句；破折号后的by crossing different species of rice plant解释前面的one way；and后面的分句也为主从复合句，which could give a higher yield than either of the original plants为定语从句修饰先行词a new plant。
From an early age he was ________ in plants. He studied agriculture in college and as a young teacher he began _________________________. He thought that the key to ______ people was to have more rice and to produce it more quickly.
