Today an electric light is the most commonly used device in our daily lives.We need them to provide light for houses，buildings，and streets.We also have handheld lights that have a backup （后備） time of more than 12 hours.The technology that we use today may be different from the past，but what we have today can be traced all the way back to the invention of the electric light.
   Efforts to create a working electric light go back to 1800 when an Italian scientist named Alessandro Volta，during his experiments on the development of electric batteries，observed that when a copper（銅）wire connected the two ends of the battery，it starts to glow due to the passage of electricity.The electric battery he invented then became the source of many electric experiments.
   Researches and developments on the electric light were continued by many inventors.It is said that the electric light was invented by 20 inventors before Thomas Edison.
   The main problem in the developments of the electric light was the filament（燈絲）inside it；it didn't last very long and melted very quickly.In this regard，Thomas Edison was very important in the development of the electric light.
   Edison started developing and testing new filaments that could last longer.He tested many materials and finally developed a filament that could last for 13.5 hours，which proved that he was moving in the right direction.He tried more than 3，000 electric light designs and 6，000 different filament materials.Finally，he found a filament that could last for more than 1，200 hours.
   Edison became successful not just because he developed a long-lasting filament.He also developed the entire electric lighting system，including the sockets（插孔）and switches.He also made the first steam-generating power station in 1882.

A．There were only a few materials to make filaments.
B．The designs for the electric light were not good enough.
C．The electric light melted in a short time.
D．The filaments could not last for a long time.

A．He developed 3，000 light bulb designs.
B．He developed the first power generating station.
C．He found a long-lasting filament.
D．He created an electric lighting system.

1．How to Raise a Child Who Loves Reading Give your kids good books to read.
   By "good" I mean quality literature that makes kids think，not just entertains them.Some books can be fun.（1）

Keep away from lightweight （內(nèi)容平庸的） books，because they may teach them to turn away from anything that makes their brains work too hard.A diet of lightweight books does not promote the patterns of thought that produce intellectual and personal excellence.
   （2）

Kids love listening to their parents read，even as they get older，so don't stop reading aloud to your children just because they can read on their own.This is a perfect opportunity to challenge their abilities，vocabulary and worldviews by reading books.
   Remove distractions （使人分心的事物）.
   With hand-held devices （3）

Parents should have these devices powered down and phones put away，and ask them to pull out their books.Once kids finally get into their books，it creates the same quiet，peaceful atmosphere home.
   Talk about books with your kids.
   （4）

Ask every family member，even the youngest，what they have read that day and what they've learned from it.This will arouse discussion and debate about the issues raised in the books.
   Give our kids paper books，not e-books.
   Studies have shown children keep information better when they read it on paper，as opposed to a screen，so avoid giving your child e-books to read.A paper book allows them to create a relationship with the book，to reread and to become familiar with a book's feel and smell.（5）

A．Read aloud to your kids.
B．Take chances to challenge your kids.
C．That's where parental responsibility comes in.
D．All these are very real parts of the reading experience.
E．Parents should inform their kids of the harmfulness of hand-held devices.
F．The dinner table is a great place to start reflective conversations about books.
G．But it's important to teach kids to appreciate books that may take effort to consume.
