Every morning my father buys a newspaper on his way to work. Every evening my mother looks through magazines at home. And every night, I look at the posters with photos of David Beckham and Yao Ming on my bedroom wall before I go to sleep. Can we imagine life without paper or print
Paper was first created about 2，000 years ago，and has been made from silk，cotton，bamboo, and since the 19th century, from wood. People learned to write words on paper to make a book. But in those days, books could only be produced one at a time by hand. As a result, they were expensive and rare. And because there weren't many books, few people learned to read.
Then printing was invented in China. When printing was developed greatly at the beginning of the 11th century, books could be produced more quickly and cheaply. As a result, more people learned to read. After that, knowledge and ideas spread quickly.
Today information can be received online, downloaded from the Internet rather than found in books, and information can be kept on CD ROMs or machines such as MP3 players.
Computers are already used in classrooms, and newspapers and magazines can already be read online. So will books be replaced by computers one day No, I don't think the poster of Yao Ming on my bedroom wall will ever be replaced by a computer two meters high!

Don’t be too surprised if you see a car going down the road without a driver in Beijing these days 26 Last month, Baidu began to test its self-driving cars on open roads in Beijing.
27 Since then, companies like Tesla, Uber and Baidu have been working to produce and test their own self-driving cars.
Self-driving cars are safer than regular cars. 28 They can remove the stress of driving and allow disabled or blind people to get around more easily.
29 In one test, researchers pointed a laser pointer（激光棒）at the car’s sensors（传感器）while it was moving. The car mistakenly thought that the laser beam was in its way and slowed down or changed the direction.
The software that is used to direct the cars may not be safe enough. 30 When we use our computers or smartphones, they sometimes crash（崩溃）without any reason. But if this happened to a self-driving car, the results could be deadly. Improvements to the software could be a solution to this problem.
A．At times, it may break down.
B．Self-driving cars began to develop in 2010.
C．It might be one of Baidu’s self-driving cars.
D．But self-driving cars have their own problems as well.
E．And they are more environmentally friendly than regular cars.

One of the easiest ways to stop the spread of disease (疾病) is to simply wash your hands. Twenty seconds of handwashing with soap and water can lower 31 and save lives. But many people, especially children, do not have good handwashing habits. One 32 is that children do not wash their hands often enough or long enough. Children may think that it is a 33 thing to do.
To help 34 this problem, Amanat Anand and Shubham Issar from India created a product called the SoaPen to turn handwashing into a fun activity.
As the name suggests, the SoaPen is a pen made out of soap. The children draw on their hands with the soap pen and then wash it off. If they do not spend enough time washing it off, the colors will remain on the children’s hands. It’s a fun 35 to teach kids how to wash their hands.
Issar said the SoaPen is invented to teach kids good handwashing habits and it ensures that children spend enough time washing their hands. This may be especially 36 in a classroom. Often a teacher does not have the time to ensure that each child has washed their hands 37 .
“Kids actually wash their hands for the proper amount of time 38 they’re drawing on their hands, and under water they have to rub (摩擦) really hard to remove the drawing. So they are actually washing their hands 39 just going under water.”
The product could have a great influence on public health. The United Nations International Children’s Emergency Fund (UNICEF) reports that 1.5 million children 40 each year as a result of diarrhea (腹泻). UNICEF says good handwashing habits could lower that number by 40 percent.
31．A．challenges B．illnesses C．possibilities D．competitions
32．A．program B．problem C．doubt D．style
33．A．serious B．special C．tiring D．difficult
34．A．solve B．explain C．collect D．refuse
35．A．smell B．size C．way D．shape
36．A．helpful B．popular C．common D．perfect
37．A．widely B．probably C．properly D．wisely
38．A．so B．because C．if D．although
39．A．because of B．as for C．thanks to D．instead of
40．A．meet B．die C．fight D．fail
