1 Again with numbers, you can describe large numbers by using hundreds, thousands or millions, e.g. There were hundreds of people in Tian'anmen Square. There were thousands of people at the football match.
再来看一下数字的说法，你可以用hundreds（数百），thousands（数千）或者millions（数百万）来描述较大的数字，如：There were hundreds of people in Tian'anmen Square.（在天安门广场有成百上千的人。）There were thousands of people at the football match.（有成千上万的人观看足球比赛。）
2 To emphasise something when you are describing it, you can use so before the main descriptive adjective, e.g. It's so big. It's so hot. It's so cool. It's so expensive.
要强调你所描述的事物，可以在主要的形容词前加so（如此地），如：It's so big.（它真大。）It's so hot.（天真热。）It's so cool.（天真冷。）It's so expensive.（这太贵了。）
