工作
参考句型：In the past, people ...
Now people ...

In the past, people wrote letters or worked on documents by hand with writing brushes and paper, which took a lot of time and effort.
Now people can use computers to send emails and deal with all kinds of work conveniently, which is much more efficient.

【分析】首先观察图片，“In the past”对应人们用毛笔和纸手写写信或处理工作，耗时费力；“Now”对应人们用电脑发邮件、处理工作，便捷高效。结合参考句型，需用一般过去时描述过去行为，一般现在时描述现在行为，体现变化。
【解析】根据图片内容，过去人们用毛笔、纸张手写写信或处理工作，花费大量时间精力；现在人们用电脑发邮件、处理各类工作，更方便高效。按照参考句型组织语言，注意时态正确，过去用动词过去式，现在用一般现在时。
【答案】In the past, people wrote letters or worked on documents by hand with writing brushes and paper, which took a lot of time and effort. Now people can use computers to send emails and deal with all kinds of work conveniently, which is much more efficient.
【知识点】一般过去时、一般现在时、看图表达
