Have you ever paid for educational podcasts (播客)or live videos? Ask some people and most of them will say yes. "Pay-for-knowledge" has been more and more fashionable these years. The contents of these "pay-for-knowledge" products are from language learning to gardening or baby-caring. Everything you think of can be found online at this moment. "Pay-for-knowledge" is on the rise(兴起).

Why is "pay-for-knowledge" industry developing so rapidly? First, its development is based on the Internet. With a fast network and a smartphone, anyone who has passed the identity(身份) check can be an online teacher, and anyone with an online account can buy "pay-for-knowledge" products that he or she wants at an affordable price. Second, people are afraid to miss any information. On one hand, people hope for more useful information.　　　　　　　　

On the other hand, such information is usually at the hands of experts (专家) who serve well-known companies and universities. Moreover, the need to learn new skills in today's job market also pushes people to learn on such educational podcasts.

The industry of "pay-for-knowledge" has proved to be lucrative. It promises possibilities of turning information into money. It is good for the development of our country and it can help sellers make lots of money. Besides, buyers can enjoy self-growth from it. What's more, this is a reflection(反映)of respect for knowledge and talents.

However, the rapid development of "pay-for-knowledge" has a few problems. For one thing, the market is full of eye-catching words such as "How to be an Industry's Expert in 5 Hours" and "15 Classes to Be a Master of Appreciating (欣赏) Classical Music", which sound like if you pay for it, you are sure to succeed. For another, a large number of customers buy them just for showing off. In fact, those who have really had self-growth after buying online courses may be the kind of people who need them least. In other words, with or without these courses, they can make it anyway, because they are those who have the ability to learn by themselves.

In general, the best is the one that suits you most. "Pay-for-knowledge" may be used as a good start for self-growth. Be careful! Otherwise, your dream of success may not come true.

1.Which of the following is TRUE according to the passage?

A."Pay-for-knowledge" products can help all the people succeed.

B."Pay-for-knowledge" products can offer people different kinds of courses.

九年级英语单选题简单题查看答案及解析

As the world becomes increasingly populated, it is also becoming alarmingly polluted. Fortunately, there are many ways that you can help deal with the negative effects that we impose(施加) on the environment. One of these is driving an electric car.

Electric cars produce about 80 percent less pollution than cars with gas-powered motors. In fact, the only reason that electric cars produce any pollution at all is that their electric energy is produced by power plants — electric cars themselves produce no waste. When energy comes from large sources such as power plants, it’s easier to control, so there’s less waste than if the energy is produced by many smaller sources, such as the gas engines in individual cars.

Furthermore, electric cars are simply more efficient than gas-powered cars for several reasons. First, electric cars have regenerative braking, which means that when you use the brakes in an electric car, the battery has a chance to recharge(再充电). On the contrary, when you brake in a gas-powered car, you actually use energy. Also, during the production of electric cars, more time and energy is spent making the design lighter and more aerodynamic so that there will be less drag(阻力) from the wind. This allows them to travel farther using less energy than a gas-powered car would use to go the same distance.

In addition to the environmental benefits of driving electric cars, there are also financial and time-saving benefits for the drivers. For one, they cost less to maintain(维修). The cost of charging an electric car is about 20 percent of the cost of gas, and electric cars require far less maintenance than gas-powered cars. This is due, in part, to the fact that electric cars have no cooling system, fan　　　　　　　　　　　　　　　　 belts, radiators, hoses, or oil — just a battery. There are fewer moving parts overall, so there are fewer possible problems. Also, after the body of an electric car gives out, the engine can be reused in another body. Electric cars can also save people time. While gas-powered cars require visits to a mechanic every few months, the only routine maintenance required by electric cars is replacing the battery every four years.

Overall, there are numerous benefits of driving an electric car. It may take a little getting used to, but in the long run, the use of electric cars can help preserve the environment and give people more time and money to be put to better use.

1.What can we learn from the second paragraph?

A.Less than 80 percent pollution is produced by cars.

B.Gas-powered cars get energy from power stations.

C.Electric cars themselves don’t produce any waste.

D.It’s difficult to control energy from power plants.

2.According to the passage, which of the following is TRUE?

A.The battery can be reused after the body of an electric car gives out.

B.Replacing the engine every four years is required for an electric car.

C.It may take no time to see the popularity of driving electric cars.

D.Electric cars cost less to maintain because of fewer moving parts.

3.What is the writer’s purpose of writing this passage?

A.To compare two kinds of cars.

B.To show a new way of driving.

C.To suggest driving electric cars.

D.To introduce a useful invention.

4.Which is the best title of the passage?

A.The Best Way to Protect the Environment

B.Electric Cars Are Worthy of a Second Look

C.The Greatest Invention in the New Century

D.Driving Electric Cars Saves Time and Money
