How did people count things before the i 47 of written numbers
At first, people used their fingers, and even their toes. H 48 , they could only count small numbers in this way.
After that, they began to make small marks on sticks and bones. This helped them count bigger numbers. They used them to count things like the days of the month, the a 49 of food and the number of animals they had.
Then people began to use tokens made from clay or small stones. This helped them count even bigger numbers. They often put the tokens on pieces of string so that they could c 50 them around easily. This developed into tools like the abacus.

参考答案
1．C
【详解】句意：——电影《流浪地球》给我们讲述了一个人们如何努力拯救地球的故事。——是的。在电影中，人类选择留在地球上，而不是逃离它。
考查介词短语辨析。as for关于，至于；thanks to由于，多亏；instead of代替，而不是；together with和……一起。根据语境可知，此处是在描述电影中人类的选择，即他们选择留在地球上，而不是逃离。所以应该用instead of来表示“而不是”的意思。故选C。

考查动词辨析。suggest建议；wonder想知道；consider考虑；regard看待。suggest doing sth.意思是建议做某事，但此句是对方给自己提建议，不是我去建议别人，A选项不符合语境；wonder常用表达为“wonder+疑问词+从句”或wonder to do sth.，B选项排除；consider doing sth.表示“考虑做某事”，Why not consider visiting Beijing 意思是“为什么不考虑去北京游玩呢”，符合语境和语法，C选项正确；regard...as...意思是“把……当作……”，D选项不符合。故选C。
