【句型剖析】
There
be句型是英语中的常见句型，意思是“有”，表示“某时/某处有某人或某物”。There
be句型的常见句子结构是：“There
be
+名词+地点/时间”。
【例句】There
is
a
dog
at
the
gate
of
the
school.
学校门口有一只狗。
【注意】当there
be句型中，be动词后面有几个并列名词作主语时，be动词的单复数形式与其最靠近的名词保持数的一致。这个原则叫“就近原则”。
【例句】There
is
an
eraser
and
three
pens
in
the
pencil
box.
铅笔盒里有一块橡皮和三支钢笔。
There
are
five
ducks
and
a
dog
on
the
farm.
农场上有五只鸭子和一只狗。
there
be与have
there
be意为“……有……”，强调存在，多表示某处有某物，不强调所属关系。
have意为“有;拥有”，多表示某人有某物，强调所属关系。

too
many
trees
.
We
waste
too
much
water

【句型剖析】
这两句中有两个短语too
many
和too
much，都表示“太多”之意。too
many用来修饰可数名词复数形式，而too
much则用来修饰不可数名词。
