難句解析：
①The goal of all will be to try to explain to a confused and often unenlightened citizenry that there are not two equally valid scientific theories for the origin and evolution of universe and life.
▲句子的主干結構是The goal... will be to try to explain...，其中explain后面接的是雙賓語：explain to sb. sth.，這里sth.是that引導的賓語從句：there are not...。
△all指代上文提到的書籍，要注意origin和evolution是并列的，而universe和life是并列的。而confused和unenlightened也是并列的。
②"Scientific" creationism, which is being pushed by some for "equal time" in the classrooms whenever the scientific accounts of evolution are given, is based on religion, not science.
▲句子的主體結構是... creationism is based... on religion, not science。其中which引導了一個非限定性定語從句which is being pushed by some for "equal time" in the classroom...修飾creationism，在這一定語從句中，whenever引導了一個時間狀語從句：whenever the scientific accounts of evolution are given。
△首先要理解非限定性定語從句的用法，另外，在閱讀中可以先跳過非限定性定語從句，只看句子的主干。
③In the last three chapters, he takes off his gloves and gives the creationists a good beating. He describes their programs and tactics, and, for those unfamiliar with the ways of creationists, the extent of their deception and distortion may come as an unpleasant surprise.
▲第一句話的主體結構是... he takes off... and gives...，第二句是and連接的兩個并列句。在第二個分句中，前面插入了一個介詞詞組：for those unfamiliar with the ways of creationists。其中unfamiliar相當于省略了who are的定語從句，修飾those。
△第一句話中，作者把寫書比喻成拳擊，因而要抨擊神造說/特創論的時候，用了takes off his gloves and gives the creationists a good beating這樣的句子。第二句中，關鍵要弄清楚，their programs and tactics，their deception and distortion中的兩個their指代的都是creationists，而不是指那些對神造論者的處事方式不熟悉的人。
④On the dust jacket of this fine book, Stephen Jay Gould says: "This book stands for reason itself." And so it does — and all would be well were reason the only judge in the creationism/evolution debate.
▲第一句話中是主語+謂語動詞+直接引語。第二句表示對第一句中的觀點的贊同，破折號后作進一步解釋；其中隱含一個if引導的狀語從句表示虛擬語氣。在正式的文體中，倒裝可以用來代替if引導的表示假設的狀語從句。were reason the only judge in the creationism/evolution debate相當于if reason were the only judge in the creationism/evolution debate。
△注意so it does的用法：so+主語+助動詞，表示對前面表述的觀點的贊同，注意這一結構與so+助動詞+主語結構的區別。后者表示“也”的意思，只用在肯定句當中。另外應注意破折號后解釋部分中的條件句里時態的運用：if條件狀語從句中使用過去時were，主句中用過去將來時would do，是作出與現在事實相反的假設。
