Step one Reading & Listening讲解
1. 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.
2. 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? 3. 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 because of 介词短语 后接名词、代词或动名词，不能接句子
I don’t buy the shirt because it is too expensive. He can’t take a walk because of the rain.
4. 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.
5. 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。

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） （2）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

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.
（2）make +sth.+adj. 形容词作宾语补足
语 make sb. do sth. 让某人做某事
（3）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。 8. 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。 10..For example, to remember the word“smiles”, we can imagine there is a “mile”
between the first letter and the last letter.
（1）between...and...两者之间。 （2）to=in order to 表目的“为了”
