1 How about the telephone?
How about...?=What about...? ……怎么样?
2 I think washing machines are helpful inventions, 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”。

provide sb. with sth. = provide sth. for sb.给某人提供某物

6 You never know, one day, you might create something amazing.
长难句分析:这是一个复合句。主句是You never know,one day作时间状语,you might create something amazing是宾语从句,其中something amazing是形容词修饰不定代词,形容词应后置。
