population意为“人口”时，是一个集合名词。它在句中作主语时，谓语动词通常用单数形式。其常用句型为“The population of +某地+ is + 数词”或“某地+ has a population of + 数词”，表示“某地有多少人口”。如：
The population of my city is three million.
◆ 当表示人口“多”或“少”时，常用形容词large，big或small修饰population。如：
The town has a large / big / small population.
◆ 当对人口数量进行提问时，要用疑问词what 或 how large。如：
What / How large is the population of your country

2). Feel free to ask me anything on today’s Great Wall tour.
在今天的长城游中，大家尽管问我任何问题，不要拘束。
feel free是英语口语中一个常用表达。若有人让你feel free to do something, 就是让你无需拘束，只管按照自己的意愿去做某事。
e.g. A: Can I use your bathroom 我可以用一下你的卫生间吗？
B: Yes, feel free. 可以，请随意。
3).The main reason was to protect their part of the country.
主要原因是为了保护国家领土。
protect作动词，意为“保护”。protect ... from ...意为“保护……不受……的侵害”，与protect ... against ...同义。如：
The sheepdog protects the sheep from / against danger.
牧羊犬保护羊群免遭危险。
【拓展】protect的名词形式为protection。如：
The children need protection.儿童需要保护。
4). As far as I know, there are no other man-made objects as big as this.
据我所知，再没有像它这样大的人造物体了。
1) as far as I know是一个固定的表达方式，还可以说so far as I know, 意思是“据我所知”。
e.g. As far as I know, Jack’s got twin sisters.就我所知，杰克有一对孪生姐妹。
They’re not coming today, so far as I know.他们今天不来了– 就我所知是这样的。
2) 句中man-made是一个合成形容词，意为“人造的”。像这样与-made复合而成的形容词不止一个。用以描述产品的生产或制造手段，特点等，常见的有：
handmade—手工制作的
homemade—家庭制作的
machine-made—机制的
tailor-made—量体定制的；特制的；定做的
甚至还有像self-made (自学而成的；自我奋斗而成的；天然形成的)可以用来描述人。
Task2. Grammar focus

一、比较级和最高级的构成

2. 不规则变化
二、比较级的用法
“比较级+than any other+可数名词单数”=“比较级+than the other+可数名词复数”表示“比其他任何……都……”, 表示最高级含义， 可与表示最高级的句子进行转换。
My father is the tallest one in my family.
=My father is taller than any other member in my family.
=My father is taller than the other members in my family.
可用于修饰形容词和副词比较级程度的副词（短语）有：much, a little, even, a lot, a bit, far等。
二、最高级的用法
1.（the + ）最高级 + in/of 短语
