Language points
1. Which invention do you think is the most important
你们认为哪项发明最重要？
“疑问词 + do you think + 陈述语序？”句式用于询问对方对于特定范围内事物的评价或看法。do you think 是插入语，去掉do you think 后仍然是一个完整的特殊疑问句，只是语气较为直接。相关句式：How do you like... 你认为……怎么样？
e.g. Which invention do you think has changed people’s lives the most
你认为哪项发明最大地改变了人们的生活？
Where do you think we should go for vacation
你认为我们该去哪里度假？
How do you like this new book 你觉得这本新书怎么样？
2. I think washing machines are a helpful invention, and both electric and gas-powered cars are cool.
长难句分析：这是一个复合句。主句主语是I，谓语是think，其后是省略了that 的宾语从句。从句是由and 连接的两个并列分句，两个分句都是主系表结构，第二个分句and both... 中both... and... 表示“……和……都”。
3. It connects people around the world and provides us with information, knowledge, and entertainment.
provide sb. with sth. = provide sth. for sb. 给某人提供某物
e.g. Parents should provide a stable environment for their children.
=Parents should provide their children with a stable environment.
父母应为孩子提供一个稳定的环境。
knowledge 作不可数名词，意为“知识；信息；知悉；了解”。但当knowledge 表示“对某一具体领域的了解或掌握程度”时，前面可以加a，形成固定搭配a knowledge of + 具体学科/ 领域。
