Unit 24 The science of farmingle

it down before you forget it．趁你还没忘记，把它写下来。

　　China was one of the first countries in the world to study the science of farming．中国是世界上最最研究农学的国家之一。

　　l）on of the first…to do…作“最早做……的之一”解，first后面跟不定式，作定语。如：

　　They are first to bear hardships，the last enjoy comforts．他们总是吃苦在前，享乐在后。

　　2）作后置定语的不定式（短语）“to study the science of farming”与其所修饰的先行调（同组）“（one of）the first countries”发生了脱离的情况。这种“脱离”或称“分裂”有时是必要的，是不可不用的。归纳起来，有下列三种：

　　a．当中心名词另有形容词、介词短语或定语从句作其后置定语时，后置不定式从句作其后置定语时，后置不定式定语应往后移置。故本句应将“in the world”置于“to study…”之前。而不能相反。另如：

　　You will remember the vain efforts of my little brother to climb to the top of that big tree.

　　b．当中心词用作句中动词的宾语，而该动词作某些不可后移的状语修饰时，该定语的后置不定式定语也正好移至状语之后。如：

　　He orders this morning to put out of the city at once.

　　试比较：This morning he received orders to put out of the city at once. 但不可说成：

　　He received orders to put out of the city at once this morning.

　　c．中心词如是句中主语，而句中谓语又比较短小，不定式比较长时，常将这种不定式移置谓语之后。如：

　　A lot of ways have been found to protect the country against attack.

　　At the meeting a decision was made to transfer a part of the student to another school.

　　Here are five pieces of advice collected from Jia Sixie’s book Oi Min Yao Shu. 这里从贾思勰的《齐民要术》中摘录的五条意见。

　　（1）此句是倒装句，here是表示地点的副词，一般不放在句首，但有时为了加强语气或引起对方的注意，可将here置于句首变成全部倒装语序，这时要注意谓语动词的位置，即主语是名词，谓语放在主语之前，主语是代词，谓语仍然放在主语之后。例如：

　　Here comes the bus. 班车来了。

　　Here he comes. 他来了。

　　（2）here用于倒装句，谓语的单复数与后面的主语保持一致。
