佳中
先做一道題
These developments have led to a far higherproportion of successful operations,
which
__________ has led to great demand fortransplants.
[A] inpart[B] in reality
[C] inturn[D]in effect
【答案】C
【題意】所有這些發(fā)展導(dǎo)致了移植手術(shù)更高比例的成功率, 而移植手術(shù)成功率的提高反過(guò)
來(lái)又導(dǎo)致移植手術(shù)更大的需求。
in turn這個(gè)詞組肯定大家都知道，意思是“俟個(gè)”、“依次”，例如：Thepateints in the waitingroom were called in the doctor’s office in turn.(候診室的病人俟個(gè)被叫進(jìn)診室就診。)
不過(guò) in turn還有一個(gè)用法，用于下列結(jié)構(gòu)：
……,and this, in turn, ……
……, and these, in turn, ……
……, which, in turn, ……
此時(shí) in turn是承聯(lián)句子的副詞性短語(yǔ)，意思是“反過(guò)來(lái)又”。 in turn 前后可用逗號(hào)點(diǎn)開(kāi)，也可不點(diǎn)開(kāi)。this、these 和 which指代前面的名詞的意思。
1）Anxiety about statusleads to high levels of stress,and this inturn leads
to healthproblems.(this 指代highlevels of stress)
對(duì)于地位的焦慮導(dǎo)致了高度緊張，這樣（而高度緊張）反過(guò)來(lái)又導(dǎo)致了健康問(wèn)題。
2）Almost everything we do depends on our moderndevices, and these inturn
dependon scientific principles.（these指代moderndevices）

3）Economic development is certainly affectingculture and customs, which,in
turn, are reacting on what is going on in theeconomy. （which指代culture
andcustoms）
經(jīng)濟(jì)發(fā)展肯定會(huì)影響文化和風(fēng)俗，而文化和風(fēng)俗又反過(guò)來(lái)作用于經(jīng)濟(jì)。
4）Skin color depends upon a number of variables,each of which, inturn, is
determined by several genes. (which 指代variables)
皮膚的顏色取決于一些可變因素，而每種可變因素又取決于好幾種基因。
●如果不是指代前面的名詞，而是指代前面句子的意思，則常用 and this intrun
…… 表示。
1）He says the company has anobligation to help the local economy, and this in
turnhelps the company.
他說(shuō)公司有義務(wù)幫助恢復(fù)當(dāng)?shù)氐慕?jīng)濟(jì), 而這反過(guò)來(lái)對(duì)公司也有好處。

露。
3）Their turbines can be smaller,since not all the air is passing through them,
and this inturn means they are quieter and use lessfuel.

更省燃油。
4）For instance, an economy that is growingquickly would tend to overheat and
this inturn is likely to lead to a higher inflation and assetbubbles.

沫。
