二、综合填空
Since digital stickers（表情包）first came out, they $\underline{\quad1\quad}$ (be) an important part of our daily online communication.
They are $\underline{\quad2\quad}$ (wide) used because they can express how someone feels or what someone wants to say.
Stickers can be interesting, foolish or serious. People can use them $\underline{\quad3\quad}$ (celebrate) or complain（抱怨）without $\underline{\quad4\quad}$ (say) a word.
A survey finds that 36% of people $\underline{\quad5\quad}$ (age) from 18 to 36 prefer pictures to words. Many of them think stickers are the best way to pass $\underline{\quad6\quad}$ (they) feelings.
While emojis are simple symbols that stand for a feeling, stickers are made up of many parts. Some of them have several $\underline{\quad7\quad}$ (mean) and have been designed to show real-life experiences.
Some people treat stickers like toys. They compete to see who can collect the most and $\underline{\quad8\quad}$ (funny) ones. Others use them as a social tool. Stickers provide $\underline{\quad9\quad}$ easy way for people to communicate with new and old friends.
No matter how stickers are used, they have become the $\underline{\quad10\quad}$ (choose) of many people.

7. 8. 9.
10.

1. since引导时间状语从句（从句用一般过去时），主句需用现在完成时，主语是they，故填have been。2. 此处修饰动词used，要用副词，wide的副词形式是widely。3. 固定搭配use sth to do sth表目的，故填to celebrate。4. without是介词，后接动名词，say的动名词是saying。5. 此处需形容词作后置定语修饰people，aged表示“……岁的”，符合语境。6. 修饰名词feelings，要用形容词性物主代词their。7. several后接可数名词复数，mean的名词形式是meaning，复数为meanings。8. 由and及前面的most可知，此处用形容词最高级funniest，修饰ones。9. easy以元音音素开头，表“一种容易的方式”，用不定冠词an。10. the后需接名词，choose的名词形式是choice。
