Text Two Friends and the Bear
Dialogue In the Dining-room
Grammar 选择疑问句
Phone”，而复数forests则表示“成片成片的森林”。
One of them said: “If we meet any wild beasts, I’ll help you and you’ll help me.”
所说的话是跟在引述动词said的后面。
"That's fine," said his friend, and they walked on.
直接引语位于句子的开头，这种情况下引述人和引述动词的主谓语序往往可以颠倒，如“said his friend”；而位于开头直接引语，即使话结束了也要用逗号。
That’s fine在口语中常常表示对某一意见的同意或赞成。
and they walked on是和前面带有直接引语的句子具有并列关系的分句，内容上是独立的，主谓语序不受前面句子的影响；副词on跟在一些不及物动词后面表示动作、行为的继续。例如:
Shall I read on?
Let’s go on with the work.
Suddenly a big bear ran out from behind a tree.
from 后面可接介词短语，如:
The dog came out from under the table. 狗从桌子下面走了出来。
I’m from out of town. 我不是本地人。
She is a writer from among the workers. 她是工人出身的作家。
The man who said he would help his friend at once got up a tree and hid himself among the leaves.
这是一个并列句，由and连接两个分句，两个分句中的谓语动词分别是got和hid；前一个分句中，the man后面跟了一个由关系代词who引导的定语从句，修饰the man，因为是特指，所以man前面要加定冠词the，定语从句中又包含了一个宾语从句he would help his friend，would是will的过去式，和前面的said保持时态上的一致。
at once 意思是“立即，马上”在这里作状语。
got up意思是“爬上”相当于“climb”。
hid是hide的过去式，其后的himself是反身代词，作hid的宾语。
who said he would help his friend 是定语从句,修饰the man；who 代表the man。类似的例子如: The girl who came this morning is Wang Ching’s sister. 今天早来的那女孩是王清的妹妹。
would 是 will 的过去形式，例如: He said:” I’ll come.” 可变为 He said he would come。
So he threw himself on the ground, closed his eyes and pretended to be dead.
注意此句连用三个动词threw，closed和pretended，表示一连串紧凑的动作。这种句法很有用。例如:
It was 7 o'clock and I had a class at 7:30. I got up，had a quick wash，and started to run.
I arrived just before the plane was to take off. I shouted and waved my ticket to the air stewardess and got in just in time.
threw oneself on是习用短语，反身代词oneself要视具体情况作相应变动。例如：
They threw themselves at the enemy. 他们一下子向敌人猛扑过去。（threw oneself at是“向……猛扑过去”）
She threw herself into his arms. 她一下子投入了他的怀抱。（threw oneself into是“投身于……”）
The bear came up and sniffed at the man's head.
