     Green is an important color in nature. It is the color of grass, the leaves on trees and most growing
plants. Sometimes, the word green means young, fresh and growing. Sometimes, it describes something
that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new
to a situation. In the 15th century, a greenhorn was a young cow or ox whose horns had not yet developed.
A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the 18th
century, a greenhorn had the meaning it has today.
     Someone who has the ability to grow plants well is said to have a green thumb. The expression comes
from the early 1990s. A person with a green thumb seems to have a magic touch that makes plants grow
quickly and well. You might say that the woman next door has a green thumb if her garden continues to
grow long after your plants have died.
     The Green Revolution is the name given some years ago to the development of new kinds of rice and
other grains. The new plants produced much larger crops. The Green Revolution was the result of hard
work by agricultural scientists who had green thumbs.
     Green is also the color used to describe the powerful emotion, envy. The green-eyed monster is not a
terrible creature from outer space. It is an expression used about four hundred years ago by British writer
William Shakespeare in his play "Othello." It describes the unpleasant feeling a person has when someone
else has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins
going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and
she does not.

翻译时,“直译”偏重于对原文的忠实,“意译”偏重于译文语气的顺畅。哪种译法更妥当,人们各执己见。依我看,直译和意译的分别根本不应存在。忠实的翻译必定能尽量表达原文的意思。思想感情与语言是一致的,相随而变的,一个意思只有一个精确的说法,换一个说法,意味就完全不同。所以想尽量表达原文的意思,必须尽量保存原文的语句组织。因此,直译不能不是意译,而意译也不能不是直译。
这段文字中,作者认为( )。

A.应随原文意思灵活选择翻译方法
B.忠实于原文思想是翻译的最高艺术
C.人为划分直译、意译本无必要
D.翻译时应尽量减少译者个人风格的影响
