Today we're going to talk about the topic of "the most useless invention". Please post "the most useless invention" in your opinion and give at least two reasons like the following example:]]> 2018-08-12 12:42:16 UTC https://padlet.com/shenghang0322/summerclass2018/wish/272753111 shenghang0322 https://padlet.com/shenghang0322/summerclass2018/wish/272753118 I believe the most useless invention is the disposable camera. Who would ever want to waste their money on a camera that can be used only once when they can take tens of thousands of photos with their cellphone? Besides, it might cost more than a cellphone!]]> 2018-08-12 12:42:32 UTC https://padlet.com/shenghang0322/summerclass2018/wish/272753118 shenghang0322 https://padlet.com/shenghang0322/summerclass2018/wish/272753122 After you have posted your opinion, please read everyone else's post and give your opinion with reasons why you agree or disagree.]]> 2018-08-12 12:42:51 UTC https://padlet.com/shenghang0322/summerclass2018/wish/272753122 165727682 https://padlet.com/shenghang0322/summerclass2018/wish/272754348 I think the most useless invention so far is the plastic bag. Plastic bags bring convenience to people's lives, but temporary convenience brings long-term harm.
The recycling value of plastic bags is low. In addition to the visual pollution caused by scattered on urban streets, tourist areas, water, roads and railways, there are potential harms. The plastic structure is stable, not easily degraded, and does not separate in the natural environment for a long time. This means that if the waste plastic does not strengthen the recycling, it will become a pollutant in the environment, long-term existence, accumulation, and great harm to the environment.]]> 2018-08-12 13:25:55 UTC https://padlet.com/shenghang0322/summerclass2018/wish/272754348 https://padlet.com/shenghang0322/summerclass2018/wish/272757469 I’am Luke                
I think the most useless thing is the solar lighter. It uses a support to hold a cigarette and install a magnifying glass on it to use the sunshine to ignite the cigarette. On the one hand,this is waste of time, and it takes a lot of time to smoking. On the other hand,if the sun is not big or the weather is bad,you can’t ignite the cigarette. Why don’ we just use lighter?
