1.Electrical Fire Safety TipsOn any given day,it's likely that most people use several different electrical devices(裝置).With electric devices being so common in modern homes,it's easy to forget that there are very real risks and angers associated with their use.Take the time to go over the rules of safe operation and make sure that everyone in your home is aware of them in order to prevent unnecessary exposure to harms and safety risks.
When an electrical short or spark does happen,it is very important to understand what to do to prevent or put out an electrical fire to keep the damage from spreading.You should,of course,call 911or other appropriate emergency services immediately in case of electrical injury or fire.The United States Fire Administration (USFA) of the Federal Emergency Management Agency (FEMA) offers a number of tips for preventing electrical fires.
◎Do not allow children to play close to small or large electrical devices.
◎Replace any tools that send out even slight electric shocks.
◎Replace any light switches that have a tendency to flash.
◎Replace any light switches that are hot to the touch.
◎Avoid overloading extension cords,sockets and plugs.
◎Do not force a three-prong plug into a two-receptacle socket.
◎Know where fuse(保險(xiǎn)絲)boxes and circuit(電路)breakers are located as well as how to properly operate them.
◎Never attempt electrical repairs or rewiring'without proper Certification and experience.
◎Do not put water on an electrical fire; use a dry fire extinguisher(滅火器)or baking soda instead.
Even though electricity is ordinary,there is still quite a bit of danger associated with improper use.Carefully observe all safety measures when using electricity to keep yourself and your family safe.

Dear Jack,
I was very happy to receive your letter telling me about your plan of opening an online bookstore with some classmates.It would be a great idea because you can learn how to manage money and how to communicate with others effectively.(高分句型一)Besides,it will be easier for you to read new books so that you can learn more.However,opening an online bookstore will take up a lot of your spare time.Apart from this,you have little experience in the field and if you don't know what books are in demand,you may lose some money.(高分句型二)
I think you should do some research first and learn how to run an online bookstore.(高分句型三)What's more,you'd better do the business during holidays.
I'm looking forward to hearing from you again.
Best wishes!
Yours,
Li Hua.
