句式精讲
1. As far as I know, there are no man-made objects as big as this.
as far as I know是一个固定表达方式，还可以说so far as I know，意为“据我所知”。
例如：

据我所知，王涛有俩弟弟。
They’re not coming this Sunday, so far as I know.
他们这周日不来了——就我所知是这样的。

3. Scientists say there are now fewer than 2,000 pandas living in the remaining forests.
本句中living in the remaining forests为现在分词短语，修饰名词pandas。
分词短语作定语时，应置于被修饰名词之后。例如：
The man standing by the window is our teacher.
站在窗边的那个人是我们老师。
（standing by the window就是一短语，也就是说不是一个单词，在此作定语表主动）
Suddenly there appeared a young woman dressed in green.
突然出现一个穿绿色衣服的女青年。（过去分词短语作定语表被动或完成）
【注意】
区别：现在分词作定语表示动作正在发生或与谓语动作同时（或基本同时）发生，表示主动意义；及物动词的过去分词作定语表完成或被动的动作；不及物动词的过去分词作定语只表完成不表被动的动作。例如：
They lived in the house facing the south.?
他们住在朝南的房子里。?(现在分词作定语表示主动意义)
The meeting held yesterday is important.?
昨天开的会议很重要。（及物动词的过去分词表被动或完成）
(2)分词短语作定语相当于一个定语从句，修饰前面的名词。例如：
The man reading a novel at the desk is my father.（现在分词表“主动、正在”）
= The man who is reading a novel at the desk is my father.??在桌边读小说的人是我父亲。
Is there anything planned for tonight? （过去分词表“被动、已经”）
= Is there anything that has been planned for tonight? 今晚有什么活动吗？
4. Pandas do not have many babies, maybe one every two years.
every+ 基数词+ 复数名词=every+ 序数词+ 单数名词，作“每(多少)”解。
例如：
every three days 每三天或每隔两天
相当于 every third day
We hand in our homework every three days.
我们每隔两天（每三天）交一次作业。
【拓展】
(1)“every other+单数名词”意为“每隔一……”。例如：
every other day 每隔一天 every other tree 每隔一棵树
(2)“every few+复数名词”意为“每隔几……”。例如：
every few days每隔几天
5. One of the world’s most dangerous sports is mountain climbing…
one of +the +形容词最高级+复数名词/代词，意为“最……之一”，当其作主语时，谓语动词用单数形式。例如：

他弟弟是这个班最高的男生之一。

If we do nothing soon there will be no more cheetahs in the world!
