1. When he died he left the Moonstone to
his sister’s daughter, Rachel, in an act of revenge,
passing on his bad luck to her. (page 112;
Reading)
in an / the act of revenge (for …)表示“采取报复……的行为，为了报复……”，相当于in
order to revenge …。
The man cut down all Mr Li’s trees at
night, in an / the act of revenge for his insult in the day.
act也常作为动词使用。
Think before acting.
The medicine was taken for a long time,
but it failed to act.
act作名词时与action的用法区别如下：
当action作可数名词时，常与act同义。
a kind act / action
但act多指具体的，短时的行为；action多指复杂的、持续的行为或行动。
在某些固定用法中，如an
act of cruelty(残忍的行为)，an
act of war（战争行为），an
act of mercy（仁慈的行为）等中，不能用action。又如，take
action（采取措施）也是固定搭配。
pass on … to sb.相当于hand
sth. down to sb.表示“把……传递给……”。
Their ancestors passed on those
traditions to the young from generation to generation.
Read the notice and pass it on to the
other students.
2. Is it coincidence or is it the
Moonstone’s bad luck that causes the tension and
strange things that happen during the rest of the evening?
(Page 112; Reading)
该句为强调句式。强调主语coincidence
or the Moonstone’s bad luck.
It is the good news that makes us all
excited.
It is … that …既可以引导一个强调句式以突出句子中的某部分，也可以引导一个主从复合句（主语从句），但两者有本质的区别：
强调句式只是为了突出某一部分而把这一部分提前到It
is … that …框架里，而把原句中其余部分原封不动地放在that之后，It
is … that …本身没有任何意义，而且除了被强调部分表示人时that可以改用who外，其他任何场合只能用that；而It
is … that …引导名词性从句时，it替代后面的从句作形式主语，后面的名词从句才是真正的主语，而且引导名词性从句的that根据句意还可改用what，who，when，where，how，why，whether等。
It is Miss Gao who will teach us English
this term.
It is not yet decided who will teach us
English this term.
3. Rachel is stubborn in resisting
his enquiries about the Moonstone to the degree that she
makes it seem as if she does not want the mystery to be
solved. (Page 113; Reading)
be stubborn in doing …表示“固执地做某事”相当于insist
on doing …。
My father was stubborn in reserving the
old house from my great grandparents.
句中的that引导的是一个同位语从句。
句中seem
as if … 与动词make构成复合宾语结构。
It seems as if the weather will turn out
fine soon, though it stormed wildly just now.
It seems as if the man were dead when he
sleeps lying on the bed.
4. Whoever is guilty must have a
stain on his or her clothes.
whoever“凡是……的人；无论谁”，引导名词性从句。
Give the book to whoever would like to
read it.
Give the book to whomever you like.
注意：
whoever与no
matter who的区别：
no matter who只能引导状语从句，而whoever既能引导状语从句，又能引导名词性从句。
No matter who breaks the law, he should
be punished.
No matter who you are, you can’t go in
without permission.
Whoever comes to the meeting will be
welcome.
Whoever comes to the meeting, he will be
welcome.
5. It turned out that Godfrey had
also seen Franklin move the diamond that night and, knowing
that Franklin would be accused, he had taken it. (Page 116;
Integrating skills Reading)
turn out表示“结果为，被证实是”，常用sb./sth.
turn out to be / do …或It
turn out that+名词从句。
That necklace which used to be thought
valuable turned out to be made of glass.
It turned out that all the experiments
they had done were unsuccessful.
句中knowing
that Franklin would be accused为分词短语作状语，这里说明原因，其中动词accuse常用“accuse
someone of something”表示“指控某人某事，控告某人犯什么罪”。
The company accused the manager of
letting out the company’s secret.
The young man was accused of robbery on
the street. |
