Pollution
is
a
danger
to
our
health.
danger是dangerous的名词形式，既可作可数名词，也可作不可数名词：
当danger表示抽象的“危险”、“风险”时，是一个不可数名词；当指具体的“危害”时，是一个可数名词。
﹡当表示“做某事的危险”时，danger
后接of
doing
sth，而不接to
do
sth。

very
ill
two
days
ago,
but
now
she
is
out
of
danger.

Pronunciation
and
speaking
在同一个意群(即短语或从句)中，如果相邻的两个词中前者以辅音音素结尾，后者以元音音素开头，就要自然地将辅音和元音相拼，构成一个音节，这就是连读。
连读的音节一般不重读，只需顺其自然地一带而过，不可以加音，也不可以读的太重。
连
读
英语连读的规则：
1.
“辅音+元音”型
2.
“辅音+半元音”型
3.
“元音+元音”型
注意：若前一个词的结尾和后一个
词的开头相同，这两个词要
连读。
