8.In cases where the explanation is unknown the scientific point of view is that there is a reason if it can only be discovered
句子中的where 是關(guān)系副詞，引導(dǎo)定語從句，修飾名詞cases，因此，in cases where the explanation is unknown可以譯為“在對一些的解釋還不為人們所知的情況下。”用關(guān)系副詞 where引導(dǎo)定語從句也是很常見的，如：
1）Let's think of a situation where this idiom can be used （我們來想一個可以使用這個習(xí)語的場合）
2）Is there a library around where we can borrow books？（附近有什么圖書館可以借書嗎？）
句子中that引導(dǎo)的是一個表語從句。表語從句和主句中的連系動詞連用，結(jié)構(gòu)為：主語＋連系動詞＋表詞從句，例如：
1）My idea is that we should do it as soon as possible（我的建議是我們應(yīng)該盡早做這件事）
2）It looks that it is going to rain（看起來天要下雨）
句子中的if…。only 在此表示尚欠缺的條件，if it can only be discovered 可以譯為“ 只是尚未被發(fā)現(xiàn)罷了”。
9. This means the ability to face the facts as they are regardless of what one has previously thought.句子中的as是一個連詞，表示方式，意思是“按照；如同；例如”
1）We must state the facts as they are.（我們必須如實地陳述事實）
2）Give me the bike as it is， I'll get it repaired （把自行車照實給我，我去修理）
Regardless of是一個常用詞組，意思是“不顧”，例如：
1）Our manager often acts regardless of consequences （我們經(jīng)理做事常常不顧后果）
2）He set out regardless of the heavy snow（他不顧天降大雪出發(fā)了）
10.The worker in science must face facts whether they are pleasant or unpleasant.
whether…or引導(dǎo)的是一個讓步狀語從句，意思是“無論，不管，”例如：
1）Whether you believe it or not it's truth （無論你信不信，那總是事實）
2）He will be here on time whether he drives or takes the train
（不管他開汽車來還是乘火車來，他總會準(zhǔn)時到達(dá)）
11.Scientists must be able to change their thinking and to adapt their theories to new facts as they are discovered.
adapt 意為“使適應(yīng)，使配合”，常指改變以適應(yīng)新的情況，后面常接介詞to， 例如：
1）Some animals will modify their behavior to adapt to their environment（有些動物會改變習(xí)性來適應(yīng)環(huán)境）
2）We have to adapt our thinking to the new conditions （我們得使自己的思想適應(yīng)新的情況）
請注意區(qū)別動詞adapt和adopt，在詞匯部分，我們已作了講解。
12. A scientific truth offers an explanation that is acceptable only in the light of what is known at a particular time
in the light of 是一個常用詞組，意思是“根據(jù)，按照；考慮到”，例如：
1） To find truth in the light of science is the only correct way（憑借科學(xué)探求真理是正確的方法）
2） We must apply Marxism in the light of China's specific conditions
（我們必須按照中國的具體情況應(yīng)用馬克思主義）
This should be discussed more fully in the light of the developments in the University
（考慮到學(xué)校的發(fā)展，這個問題應(yīng)該討論得更充分一些。）
