Step 9 Language points and summary1. China has the biggest population in the world. 中國是世界人口最多的國家。population意為“人口”時，是一個集合名詞。它在句中作主語時，謂語動詞通常用單數(shù)形式。其常用句型為“The population of +某地+ is + 數(shù)詞”或“某地+ has a population of + 數(shù)詞”，表示“某地有多少人口”。如：The population of my city is three million. 當(dāng)表示人口“多”或“少”時，常用形容詞large，big或small修飾population。如：The town has a large / big / small population. 當(dāng)對人口數(shù)量進(jìn)行提問時，要用疑問詞what 或 how large。如： What / How large is the population of your country?【運(yùn)用】完成句子，每空一詞。(1) 這個國家人口少。The country _ _ _ _. (2) 我的家鄉(xiāng)有100萬人口。My hometown _ _ _ _ one million. (3) 北京有多少人口？_ _ _ _ _ Beijing? 2. Feel free to ask me anything on todays Great Wall tour. 在今天的長城游中，大家盡管問我任何問題，不要拘束。feel free是英語口語中一個常用表達(dá)。若有人讓你feel free to do something, 就是讓你無需拘束，只管按照自己的意愿去做某事。e.g. A: Can I use your bathroom? 我可以用一下你的衛(wèi)生間嗎？B: Yes, feel free. 可以，請隨意。3. As far as I know, there are no other man-made objects as big as this. 據(jù)我所知，再沒有像它這樣大的人造物體了。1) as far as I know是一個固定的表達(dá)方式，還可以說so far as I know, 意思是“據(jù)我所知”。e.g. As far as I know, Jacks got twin sisters. 就我所知，杰克有一對孿生姐妹。 Theyre not coming today, so far as I know. 他們今天不來了 就我所知是這樣的。2) 句中man-made是一個合成形容詞，意為“人造的”。像這樣與-made復(fù)合而成的形容詞不止一個。用以描述產(chǎn)品的生產(chǎn)或制造手段，特點(diǎn)等，常見的有：handmade手工制
