◆知识探究
Step one Reading & Listening讲解
When we make new memories, we lose old ones.
当我们形成新的记忆时,就会推动旧的记忆。
lose(lost, lost)及物动词,“失去,丢失”。可指因事故或过失失去原有的东西,也可指人陷入深思中。
I can’t write to Mr Green because I have lost his address.
Because they enjoy learning about memory. 因为他们喜欢了解记忆力。
enjoy及物动词,“享......之乐,欣赏,喜欢”,后接名词,代词或动名词作宾语,不能接动词不定式。 Enjoy doing sth. 喜欢做某事
Many people enjoy traveling during holidays.
【拓展】enjoy后接反身代词,反射代词就应在人称和数上与enjoy的主语保持一致,enjoy oneself与hav a good time和have fun同义,“玩得开心”。
Did you enjoy yourselves at the party last night
= Did you have a good time / have fun at the party last night
Because they want to help students improve their memory.
因为他们想帮助学生提高记忆力。
because连词,“因为”,其后接从句,陈述原因或理由,用来回答why引导的特殊疑问句。
-- Why isn’t Li Ping here
-- Because he is ill.
注意:because 从属连词,引导原因状语从句,在英语中because 和so不能同时出现在一个句子中,只能用其一,与汉语表达不同。有类似用法的还有although(though)与but,它们也不能同时出现在一个句子中。
辨析:because与because of
because 连词 引导原因状语从句,表示直接明确的原因或理由 I don’t buy the shirt because it is too expensive.
because of 介词短语 后接名词、代词或动名词,不能接句子 He can’t take a walk because of the rain.
To write it down. 把它写下来。
write down 写下,记下,是动副短语,如果名词作宾语,一般位于write down之后中,也可位于writh和down 之间;如果代词作宾语,必须位于writh和down 之间。
Please write down these new words.
The word is important. Please write it down.
A great way to help you remember something is to imagine a picture of it in your mind.
帮你记住某件事的一种有效方法就是在大脑里想像出它的一副画面。
(1)动词不定式短语to help you remember somthing作定语,修饰名词短语a great way; 动词不定式
to imagine a picture of it in your mind作表语。
I have a lot of work to do today. 我今天有很多工作要做。 (动词不定式作定语)
He had no chance to go to school thoese years. 那些年,他没有机会上学。 (动词不定作定语)
His dream is to be a doctor. 他的梦想是成为一名医生。 (动词不定式作表语)
help sb with sth 在某方面帮助某人 help oneself (to)请自便
with the help of 在......方面帮助某人 can’t help doing sth 忍不住做某事
imagine 想象 +名词、动名词、从句
e.g.We can’t imagine life without any hardships.

6. If you make the picture big, strange or silly,you will remember it better.
如果你把这幅图画想象地很大、很奇怪,或是很愚蠢,你将会更好地将它记住。
(1)if 引导的条件状语从句,条件状语从句中的动词多用一般现在时,主句中的动词多用一般将来时,即主将从现原则.
I shall go if she asks me.
make +sth.+adj. 形容词作宾语补足语 make sb. do sth. 让某人做某事
remember to do sth.记得去做某事 remember doing sth. 记得做过某事
7. This makes it the longest word in the world.
当不定式、动名词、从句等复杂成分用作宾语且其后跟有宾语补足语时,通常会在宾语补足语前使用形式宾语it,而将真正的宾语移至句末,其基本结构为“动词+it+宾语补足语+不定式(动名词或从句)”。
如: I find it difficult to do the job well. 我发现做好这件事不容易。
Remember :a picture is worth a thousand words.记住:一副图画,值1000个单词。
be worth +V. ing 值得......的
e.g. This house is worth a lot of money.
The film is worth seeing.
翻译:这个茶杯值30元。____________________________________
9.A good method for remembering the spelling of a word is to make a short sentence with each other of the word.
(1)a method for+ doing sth. 一个做......的方法
(2)不定式作表语表示具体动作或将来动作;
①To be kind to the enemy is to be cruel to the people.
②My chief purpose is to point out the difficulties of the matter.
③What I would suggest is to put off the meeting.
当主语和表语都是不定式时,其含义一是条件,一是结果(例①)。
当主语是aim,duty,hope,idea,mista ke,plan,purpose,suggestion等为中心词的名词词组(例②)时, 或以what引导的名词性分句(例③),不定式说明主语的内容。
.For example, to remember the word“smiles”, we can imagine there is a “mile”
between the first letter and the last letter.
between...and...两者之间。 (2)to=in order to 表目的“为了”
For example, if you want to remember how to spell the word”because”,......
疑问词who,what,which,when,where,whether,how后可接不定式构成不定式短语,句中作主语、宾语、表语等。
①When to leave for London has not been decided yet. (不定式在句子中做主语)
②Mr. Smith didn't know whether to leave or stay there. (不定式在句子中做宾语)
③I asked Professor Xu how to learn English well. (不定式在句子中做直接宾语)
④The question was where to get the medicine needed. (不定式在句子中表语)
以上例句中疑问词+不定式部分,均可转换为相应的从句形式。
如:①When we shall leave…③…how I could learn……
经常在这种结构中使用的动词有:
consider,decide,discover,explain,find out,forget,hear,know,lea rn,observe,understand,wonder等。
You will forget something very quickly unless you understand it well.
如果你没有理解的话,你很快就会忘记它。
unless= if ...not 引导条件状语从句“如果不;除非”,也要遵循“主将从现”原则
e.g.Unless he studied hard, he will never pass the exams.
(2)forget to do sth 忘记去做某事 forget doing sth 忘记做了某事
Sorry,I forgot to bring the book.(对不起,我忘了带书了。)
I forgot borrowing a book from you.(我忘记曾经向你借过书这件事)
forget quickly , understand well 副词修饰动词
13.It’s easier to remember these steps if you understand how the water cycle works.
动词不定式作主语时常用it作形式主语,而往往将动词不定式放在谓语或表语之后。
如: It's not easy to learn a foreign language well. (=To learn a foreign language well is not easy.)
学好一门外语不容易。
在此句型中,如果要说明动词不定式的动作是谁做的,可在不定式前加一个for 引起的短语,作不定式的逻辑主语。
如: It's difficult for us to finish the work. 对我们来说,完成这项工作很困难。
It's hard for me to answer your question. 要我回答你的问题很难。
但是,如果表语是kind, nice, right, wrong, clever, polite 等描述行为者的性格、品质的形容词,则应在不定式前加一个of 引起的短语。如:
It's very kind of you to help me.你能帮我,真好。
How to scientists think about that sound similiar 科学家对发音相似的单词是怎样认为呢?
sound此处作连系动词,”听起来“,其后通常接形容词作表语,常见短语:sound like听起来像,后跟名词
The music sounds very nice. 这音乐听起来十分悦耳。
Paris sounds like a city that I like. 巴黎听起来像是我喜欢的城市。
similiar 相似的,类似的,常见短语be similiar to与......相似
