tell的用法
tell意为“讲，告诉”。
tell sb about sth 表示“告诉某人某事”；
tell sb to do sth 意为“告诉某人去做某事”。
例如：
Tell me all about it. 告诉我关于这件事的一切。
She tells me to do this job. 她告诉我做这项工作。
Language point
tell后可接双宾语，即tell sb sth/ tell sth to sb,意为“告诉某人某事”。例如：
She tells me a thing.
=She tells a thing to me. 她告诉我一件事。
【注意】tell是不规则动词，其过去式为told。
Language point
There be 句型的过去式
There be 句型的过去式是There was…或There were…，There was +单数名词或不可数名词，
There were +复数名词。
例如：
There was a book on the desk. 书桌上有一本书。
There were some books on the desk. 书桌上有一些书。
Language point
be going to 的用法
be going to是一般将来时的一种表现形式，表示将来某个时间将要发生的动作或存在的状态，意思为“打算，将要”。其中“be”会根据主语的人称变化成“is, am, are”等形式，to是不定式符号，跟在它后面的动词必须是原形。
例如：
I am going to work hard this term.
我打算这学期努力学习。
He’s going to visit his grandparents next Sunday.
下星期日他将看望他的祖父母。
Language point
take 表示“花费”

主语是人。
例如：
I took three hours to get home last night.
昨天晚上我花了三个小时才到家。
Language point
主语是活动。
例如：
Painting the kitchen took me all week.油漆厨房花了我整整一个星期。
主语是it，it为形式主语，其后的动词不定式短语为真正的主语，一般现在时的时态下，其结构为It takes sb some time to do sth.
例如：
It takes him an hour to do his homework in the evening.
晚上他要花一个小时做作业。
Language point
or的用法
or用于否定句相当于“and +前面所有否定词”，表示“也不，亦不”的意思。
例如：
He never smokes or drinks. 他从来不吸烟也不喝酒。
There is no air or water on the moon. 月球上没有空气也没有水。
Language point
or用于选择疑问句，意为“还是，抑或”，位于若干选项的末项前，or以前各项用升调，末项用降调。回答用选定的一项，不能用Yes 或No。
例如：
—Do you like red or blue 你喜欢红色还是蓝色？
—I like blue. 我喜欢蓝色。
