A PIONEER① FOR ALL PEOPLE
Yuan Longping，known as the“father of hybrid② rice”[1]，was one of China's most famous scientists．Yet，he considered himself a farmer because he continually worked the land③ in his research．Indeed，his slim④ but strong body was just like that of millions of Chinese farmers，to whom he had devoted⑤ his life[2]．
[1]known as...為過去分詞短語作定語，修飾Yuan Longping。be known as...意為“作為……而出名”。
[2]to whom he had devoted his life是“介詞＋whom”引導的定語從句，修飾先行詞farmers。devote...to是固定搭配，這里介詞to被提到了關系代詞前面。
Yuan Longping was born in 1930 in Beijing．His parents wanted him to pursue a career⑥ in science or medicine．However，what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage⑦ of food to eat．[3]To tackle⑧ this crisis⑨[4]，he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing．
[3]本句是主從復合句。what concerned him most是主語從句；that farmers often had poor harvests...是表語從句。
[4]To tackle this crisis是動詞不定式短語作目的狀語。
After graduating in 1953，he worked as⑩ a researcher．Yuan Longping realised that larger fields were not the solution ．Instead，farmers needed to boost yields in the fields they had[5]．How this could be done[6] was a challenging question at the time．Yuan was convinced that the answer could be found in the creation of hybrid rice．A hybrid is a cross between two or more varieties of a species ．One characteristic of hybrids is that they usually attain a higher yield than conventional crops[7]．However，whether it was possible to develop a hybrid of self-pollinating plants such as rice[8] was a matter of great debate．The common assumption then was that it could not be done[9]．Through intense effort，Yuan overcame enormous technical difficulties to develop the first hybrid rice that could be used for farming in 1974[10]．This hybrid enabled farmers to expand their output greatly．
[5]此處是省略引導詞的定語從句，修飾先行詞the fields。當引導詞that/which在從句中作賓語時，可以省略。
[6]此處是主語從句，引導詞是how，整個從句一起作主語。
[7]that they usually attain a higher yield than conventional crops 是表語從句，引導詞是that，在句中沒有詞義，只起連接作用，不可省略。
[8]whether it was possible...rice是由whether引導的主語從句。
[9]that it could not be done是表語從句，引導詞是that，在句中沒有詞義，只起連接作用，不可省略。
[10]that could be used for farming in 1974是由that引導的定語從句，修飾先行詞the first hybrid rice，引導詞that在從句中作主語，不可省略。
　　Today，it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated from Yuan's hybrid strains [11]，and his strains have allowed China's farmers to produce around 200 million tons of rice per year．Yuan's innovation has helped feed not just China，but many other countries that depend on rice as well，such as India and Vietnam[12]．Because of his invaluable contributions，Yuan Longping received numerous awards both in China and abroad．
[11]it is estimated that...中it是形式主語，后面的that從句是真正的主語。that只起連接作用，不作任何成分。本句中generated from Yuan's hybrid strains是過去分詞短語作定語，可轉化為定語從句which are generated from...。
[12]that depend on rice as well，such as India and Vietnam是定語從句，修飾先行詞countries，that在定語從句中作主語。
Given that[13] Yuan's hybrids made him quite wealthy，one might think he would have retired to a life of leisure ．However，this is far from the case ．Deep down ，Yuan was still very much a farmer at heart．As a man of the soil ，he cared little for celebrity or money．Instead，he made large donations to support agricultural research．
[13]given that引導條件狀語從句，意為“考慮到，鑒于”。
What impressed people most about Yuan Longping[14] was his ongoing ability to fulfil his dreams ．Long ago，he envisioned rice plants as tall as sorghum ，with each ear of rice as big as a broom ，and each grain of rice as huge as a peanut．He succeeded in producing a kind of rice that could feed more people at home and abroad[15]．His later vision for “seawater rice” also became a reality，and potentially opened up nearly one million square kilometres of salty land in China for rice production．Even in his later years，Yuan Longping was still young at heart and full of vision，and everyone was always excited to see what he would dream up next．
[14]What impressed people most about Yuan Longping是由what引導的主語從句。what在從句中作主語，意思是“……的事情”。
[15]that could feed more people at home and abroad是定語從句，修飾先行詞a kind of rice，that在定語從句中作主語。
全民先鋒
袁隆平，被稱為“雜交水稻之父”，是中國最著名的科學家之一。然而，他自認為是個農民，因為在研究中他不停地耕種土地。確實，他瘦削但結實的身軀看起來和他為之奉獻了一生的千千萬萬的中國農民一樣。
袁隆平1930年出生于北京。他的父母希望他從事科學或醫學方面的事業。然而，最讓他擔心的是農民經常糧食歉收，有時甚至嚴重缺乏吃的食物。為了應對這一危機，他選擇了學習農業，并在重慶的西南農學院接受教育。
1953年畢業后，他從事研究工作。袁隆平意識到，解決問題的辦法并不是擴大農田面積，而是農民們需要提高他們已有土地上農作物的產量。如何做到這一點在當時是一個具有挑戰性的問題。袁隆平確信，答案可以在雜交水稻的培育中找到。雜交作物是一個物種的兩個或兩個以上變種的雜交。雜交作物的一個特點是它們的產量通常比傳統作物高。然而，能否培育出一種自花傳粉的雜交植物，如水稻，是一個有很大爭議的問題。當時人們普遍認為這是不可能的。通過不懈的努力，袁隆平克服了巨大的技術難題，1974年，他培育出了第一種可用于農業生產的雜交水稻。這種雜交水稻使農民大大增加了產量。
據估算，現在中國國內消費的稻米有大約60%來自袁隆平的雜交水稻品種形成的作物，這些品種(形成的作物)讓中國農民每年能夠生產出大約兩億噸稻米。袁隆平的創新不僅幫助養活了中國，也養活了許多其他依賴大米的國家，如印度和越南。因為他的不可估量的貢獻，袁隆平在國內外獲獎無數。
考慮到雜交水稻使袁隆平變得相當富有，人們可能認為他會退休享受閑適的生活。然而，事實遠非如此。實際上，袁隆平在內心深處仍然是一位農民。作為一位農民，他不太在乎名聲和金錢。相反，他大量捐款以支持農業研究。
袁隆平最讓人印象深刻的是他不斷實現夢想的能力。很久以前，他設想了一種像高粱一樣高的水稻，每一穗米都像掃帚一樣大，每一粒米都像花生一樣大。他成功地培育出一種可以養活國內外更多人的水稻。他對“海水稻”的最新設想也已成為現實，并可能在中國開辟近100萬平方公里的鹽堿地，用于水稻生產。即使在他生命的最后幾年，袁隆平的內心仍然年輕，充滿了遠見，那時每個人都在等著看他接下來會夢想什么。

A PIONEER① FOR ALL PEOPLE
Yuan Longping，known as the“father of hybrid② rice”[1]，was one of China's most famous scientists．Yet，he considered himself a farmer because he continually worked the land③ in his research．Indeed，his slim④ but strong body was just like that of millions of Chinese farmers，to whom he had devoted⑤ his life[2]．
[1]known as...為過去分詞短語作定語，修飾Yuan Longping。be known as...意為“作為……而出名”。
[2]to whom he had devoted his life是“介詞＋whom”引導的定語從句，修飾先行詞farmers。devote...to是固定搭配，這里介詞to被提到了關系代詞前面。
Yuan Longping was born in 1930 in Beijing．His parents wanted him to pursue a career⑥ in science or medicine．However，what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage⑦ of food to eat．[3]To tackle⑧ this crisis⑨[4]，he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing．
[3]本句是主從復合句。what concerned him most是主語從句；that farmers often had poor harvests...是表語從句。
[4]To tackle this crisis是動詞不定式短語作目的狀語。
After graduating in 1953，he worked as⑩ a researcher．Yuan Longping realised that larger fields were not the solution ．
Instead，farmers needed to boost yields in the fields they had[5]．How this could be done[6] was a challenging question at the time．Yuan was convinced that the answer could be found in the creation of hybrid rice．A hybrid is a cross between two or more varieties of a species ．One characteristic of hybrids is that they usually attain a higher yield than conventional crops[7]．
However，whether it was possible to develop a hybrid of self-pollinating plants such as rice[8] was a matter of great debate．
The common assumption then was that it could not be done[9]．
Through intense effort，Yuan overcame enormous technical difficulties to develop the first hybrid rice that could be used for farming in 1974[10]．This hybrid enabled farmers to expand their output greatly．
[5]此處是省略引導詞的定語從句，修飾先行詞the fields。當引導詞that/which在從句中作賓語時，可以省略。
[6]此處是主語從句，引導詞是how，整個從句一起作主語。
[7]that they usually attain a higher yield than conventional crops 是表語從句，引導詞是that，在句中沒有詞義，只起連接作用，不可省略。
[8]whether it was possible...rice是由whether引導的主語從句。
[9]that it could not be done是表語從句，引導詞是that，在句中沒有詞義，只起連接作用，不可省略。
[10]that could be used for farming in 1974是由that引導的定語從句，修飾先行詞the first hybrid rice，引導詞that在從句中作主語，不可省略。
　　Today，it is estimated that about 60 percent of domestic rice consumption in China is comprised of crops generated from Yuan's hybrid strains [11]，and his strains have allowed China's farmers to produce around 200 million tons of rice per year．Yuan's innovation has helped feed not just China，but many other countries that depend on rice as well，such as India and Vietnam[12]．Because of his invaluable contributions，Yuan Longping received numerous awards both in China and abroad．
[11]it is estimated that...中it是形式主語，后面的that從句是真正的主語。that只起連接作用，不作任何成分。本句中generated from Yuan's hybrid strains是過去分詞短語作定語，可轉化為定語從句which are generated from...。
[12]that depend on rice as well，such as India and Vietnam是定語從句，修飾先行詞countries，that在定語從句中作主語。
Given that[13] Yuan's hybrids made him quite wealthy，one might think he would have retired to a life of leisure ．However，this is far from the case ．Deep down ，Yuan was still very much a farmer at heart．As a man of the soil ，he cared little for celebrity or money．Instead，he made large donations to support agricultural research．
[13]given that引導條件狀語從句，意為“考慮到，鑒于”。
[14]What impressed people most about Yuan Longping是由what引導的主語從句。what在從句中作主語，意思是“……的事情”。
[15]that could feed more people at home and abroad是定語從句，修飾先行詞a kind of rice，that在定語從句中作主語。
全民先鋒
袁隆平，被稱為“雜交水稻之父”，是中國最著名的科學家之一。然而，他自認為是個農民，因為在研究中他不停地耕種土地。確實，他瘦削但結實的身軀看起來和他為之奉獻了一生的千千萬萬的中國農民一樣。
袁隆平1930年出生于北京。他的父母希望他從事科學或醫學方面的事業。然而，最讓他擔心的是農民經常糧食歉收，有時甚至嚴重缺乏吃的食物。為了應對這一危機，他選擇了學習農業，并在重慶的西南農學院接受教育。
1953年畢業后，他從事研究工作。袁隆平意識到，解決問題的辦法并不是擴大農田面積，而是農民們需要提高他們已有土地上農作物的產量。如何做到這一點在當時是一個具有挑戰性的問題。袁隆平確信，答案可以在雜交水稻的培育中找到。雜交作物是一個物種的兩個或兩個以上變種的雜交。雜交作物的一個特點是它們的產量通常比傳統作物高。然而，能否培育出一種自花傳粉的雜交植物，如水稻，是一個有很大爭議的問題。當時人們普遍認為這是不可能的。通過不懈的努力，袁隆平克服了巨大的技術難題，1974年，他培育出了第一種可用于農業生產的雜交水稻。這種雜交水稻使農民大大增加了產量。
據估算，現在中國國內消費的稻米有大約60%來自袁隆平的雜交水稻品種形成的作物，這些品種(形成的作物)讓中國農民每年能夠生產出大約兩億噸稻米。袁隆平的創新不僅幫助養活了中國，也養活了許多其他依賴大米的國家，如印度和越南。因為他的不可估量的貢獻，袁隆平在國內外獲獎無數。
考慮到雜交水稻使袁隆平變得相當富有，人們可能認為他會退休享受閑適的生活。然而，事實遠非如此。實際上，袁隆平在內心深處仍然是一位農民。作為一位農民，他不太在乎名聲和金錢。相反，他大量捐款以支持農業研究。
袁隆平最讓人印象深刻的是他不斷實現夢想的能力。很久以前，他設想了一種像高粱一樣高的水稻，每一穗米都像掃帚一樣大，每一粒米都像花生一樣大。他成功地培育出一種可以養活國內外更多人的水稻。他對“海水稻”的最新設想也已成為現實，并可能在中國開辟近100萬平方公里的鹽堿地，用于水稻生產。即使在他生命的最后幾年，袁隆平的內心仍然年輕，充滿了遠見，那時每個人都在等著看他接下來會夢想什么。
