2. They will arrive in New York at noon.他们将于中午到达纽约。
3. I just arrived at school.
Step2重点难点解析
难点一、There be 句型需要注意的几点:
1. There be句型表示的是“有”的意思,翻译是不需要“这”
There is a book on the table. 有一本书在桌子上。
不能翻译成:这有一本书在桌子上。
2. 句型中的be动词应用:
is:主语是可数名词单数或者不可数名词时
are:主语是可数名词复数时
There is a pen on the desk. 有一支钢笔在桌上。
There is some bread on the table. 有一些面包在桌上。
There are two children in the room.
★ 主谓一致:
如果there be 句型后的主语是几个并列的名词时,则根据离谓语be最近的动词的数确定be的形式,即该名词时单数,be用is;如果该名词是复数,be用are:
There is a bird and two boys in the tree. 树上有一只鸟和一个男孩。
There are some apples and a bird in the tree.
3. 与have(has)的区别
两者都有“有”的意思,但there be 句型强调“某处有某物/某人”,着重“存在”的状态;have 强调“某人有某物”,着重“所有、拥有”
There are three children in my family. 我家有三个孩子。
I have three children. 我有三个孩子。
★ 注意:正因为两者之间的这种区别,There be 句型中不能出现have或者has
难点二、表示方位的介词或者介词短语
1. at 在……地点
He stands at the end of the line. 他站在最后一排的最后。
Let's meet at the school gate.
2. in 在……里面,在……(大地点)
We will have a meeting in the classroom. 我们将在教室开会。
There are many Chinese restaurant in New York.
3. on 在……上面

6. in front of ... 在……的前面,前部(空间范围外)
There is a park in front of the house. 这所房子前面有个公园。
in the front of ... 在……的前面(空间范围内)

★ 对比:There is a table in the front of the classroom.

7. across from...在……对面
The school is across from my house. 学校在我家的对面。
8. next to 在……隔壁
The building next to the post office is the bank. 邮局旁边的建筑物是银行。
难点三、play the guitar
play 作“演奏某一乐器”时,乐器前面需要定冠词the; 而作“参加(比赛或体育活动)”时,不用定冠词,如:play football,play tennis, play chess等等。
难点四、arrive, get , reach 辨析:
1. arrive in 大地点, arrive at 小地点,如:
We arrived at the village at five in the afternoon. 我们下午五点到达那个小村庄。
When did you arrive in Beijing? 你们是何时到北京的啊?
A. get to 地点名词:

B. reach 是及物动词,后边直接跟地点名词。
