Water is important to all living things but some areas in the world are short of water a lot.So we should try to protect and save water.
A group of students from Zhejiang University have successfully developed an"air hand﹣washing machine".The machine uses an infrared ray induction system （红外线感应系统），which can feel the presenceof our hands.If it feels there are hands，the water with the air will come from the tap.And it has been proven that it is nearly as effective as traditional hand﹣washing.It uses only ten percent of the water that regular hand﹣washing does.The students have even set up a company to introduce the product to the public.
Li Qizhang，a member of the team that developed the machine，told a reporter that a model of their machine had already been placed in a classroom building at the university and it worked very well.
In 2014，a student called Chen Puyang first thought of the idea while he was washing his hands.Washing one's hands uses a lot of water，Chen thought.Would it be possible to replace the water with air？ Others may not give the question a second thought.However，for Chen and Li，who were studying fluid mechanics （流体力学） at the time，this was considered to be an excellent idea.
Soon，Chen，Li and several classmates started on the project.After a year of research，the team cam up with a gravity﹣driven （重力驱动） hand﹣washing machine successfully.

| Dear Dr． Green， My relationship with my mother is worse and worse now． It seems she's never tired of talking． She talks here and there，day and night． More seriously， I feel like we don't have much common． She doesn't always understand what I'm trying to say． What should I do？ Yours， Jim |
Dear Jim， I know how you feel． It's not easy being your age． And it 's not easy being a mother， either． It's common for kids to have trouble talking with parents， and talkative mothers are not new to teenagers． But remember， she's nagging（叨唠） you because she just wants what's best for you． Talking is her way to show love and care． And she also wants to know more about you． After a day 's work． she's tired， too． But she will never be tired of caring about you． Kids should learn to understand and care about parents． In my opinion， it's helpful to share school life with her． Then， you talk and she listens． Doing some housework together with her is another good way for you two to know each other better． And if possible， often tell her your feelings about the things around you． Always keep in mind： be polite and patient． Yours， Dr．Green |

What can be both red or green， round or sharp， big or small， and more importantly， loved or hated by someone？ Yes， the answer is chilies （辣椒）．
Many of us in China enjoy adding chilies to our food， but did you know that this spicy （辣 的） vegetable could also be dangerous？ A 34﹣year﹣old US man recently ended up in hospital after eating a Carolina Reaper， the spiciest chili people have known so far． After taking just a single bite of one， the man suffered from serious headaches in the following days， reported BBC News．
In fact， eating spicy food causes stomachache and headache． But if chilies are harmful， why do people like to eat this vegetable？ So what makes people love chilies so much？ The human body is influenced by natural chemicals that produce "a sense of happiness"， noted BBC News．
And chilies do good to people in another way． Scientists found that the death rate of those who eat spicy food once or twice a week is 10 percent lower than those who eat it less than once a week． The death rate is 14 percent lower for those who eat spicy food six to seven times a week． This encourages people to eat more spicy food to improve health and bring less death risk at an early age． So， don't worry if you love spicy food． It seems that chilies are actually good for us．
