"Pay-for-knowledge" is on the rise（興起）.
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 informatijye.ai.On one hand，people hope for more useful information.
On the other hand，such information is usually at the hands of experts （專家） 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 （欣賞） 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．If you see a group of people dancing and singing on the street or in the railway station，you don't need to feel surprised.They are a flash mob（快閃族），which is a group of people who come together suddenly in a public place，do something unusual for a brief period of time，and then quickly break up.They are usually organized with the help of the Internet or other digital communication network.
At a predetermined time，they gather and perform some distractions（消遣）such as waving their hands and exchanging books.Then，they quickly break up before the police can arrive.Using mobile phones the flash mob can change its location if the first one has been replaced for any reason.
Bill Lasik，senior editor of Harper's Magazine，organized the first flash mob in Manhattan in May 2003 and the first successful flash mob came together on June 3，2003--after the first attempt was foiled at Macy's department store.Lasik claimed that the activity was designed to make fun of hipsters（時(shí)髦的人），and call attention to the cultural atmosphere.
Flash mob gatherings can sometimes shock people.Such an activity might seem amusing and untrue，but it also might frighten people who are not aware of what is taking place.Undoubtedly，flash mobs can serve as good political tools in any direction.They also have great economic potential，such as using flash mobs to advertise a product.
The flash mob is now becoming more and more popular.People use it to do many things.For example，in 2009，Michael Jackson's fans took part in a flash mob to remember him.Hundreds of his fans gathered singing and dancing Michael's famous song Beat It together.Flash mobs give people from all walks of life an opportunity to come together to create a memory.

2．The world is a greener place than it was 20 years ago．Recent NASA satellites data（2000-2017）have shown that human activities in China and India dominate this greening of the planet，thanks to ambitious tree-planting programmes in China and intensive agriculture in both countries．
The researchers from Boston University found that global green leaf area has increased by 5 percent in the new century，an area equal to all of the Amazon rainforest．China alone accounts for 25% of the global net increase in leaf area with only 6.6% of global vegetated area．China's contribution comes in large part from its programmes to conserve and expand forests，taking up about 42 percent of the greening．The greening from farmlands in China is about 32%，but that in India is about 82%．
Rama Nemani，a research scientist at NASA's Ames Research Centre and a co-author of the study said， "When the greening of the Earth was first observed，we thought it was due to a warmer，wetter climate and fertilization from the added carbon dioxide in the atmosphere．But with data from NASA satellites，scientists realized that humans are also contributing，which was all against our expectations．"
Nemani sees a positive message in the new findings． "Once people realize there is a problem，they tend to fix it，" he said． "In the 1970s and 1980s in India and China，the situation around vegetation loss was not good．In the 1990s，people realized it，and today things have improved．Humans are incredibly resilient．That is what we see in the satellite data．"
However，the researchers rang bells as well．They said that the gain in global greenness did not necessarily make up for the loss of natural vegetation in regions like Brazil and Indonesia．
（1）What is the second paragraph mainly about？
A．The decreasing size of the Amazon rainforest．
B．China's bigger contribution to global greening．
C．Total global green leaf area in the new century．
D．China's programmes to conserve and expand forests．
（2）What surprised scientists regarding global greening？
A．Human activities．
B．Suitable for analyzing data．
C．A warmer and wetter climate．
D．Carbon dioxide in the atmosphere．
（3）What does the underlined word "resilient" probably mean？
A．Good at making programmes．
B．Suitable for analyzing data．
C．Able to make corrections．
D．Active in planting trees．
（4）What does the last paragraph imply？
A．It is urgent to protect global natural resources．
B．Much remains to be done for global greenness．
C．Brazil and Indonesia lose most of their vegetation．
D．Global greenness needs all countries to work together．發(fā)布：2024/12/20 5:0:3組卷：7引用：1難度：0.6 -
3．Our dog Sandy is a golden retriever（尋回犬）.Once we performed an experiment to see how keen his nose was.There was one particular pile that must have had hundreds of sticks.We picked up one stick carved an X on it，walked away from the pile and then threw it back into the pile，not once but a dozen times into the pile.It was impossible for us to tell with any certainty which slick we had originally chosen.Each time he brought back that stick，It wasn't the shape or the size or the look of the stick that he used to pick it out from all the others.It was the smell we left on the stick.It is hard to imagine，hut for dogs every living creature has its own distinctive smell.
The noses of people have about 5 million cells that sense smell.Dogs' noses have anywhere from 125 to 300 million cells.Moreover，these cells are closer to the surface than cells in our noses，and more active.It has been estimated that dogs such as Sandy have noses that are a million times more sensitive than ours.Clothes that we haven't worn for weeks，and places we've only touched lightly indicate our presence to dogs.
His ears are also remarkable.He can hear sounds that humans can't and at distances which are astonishing.It is over our head to know and understand that world.Yet we have the advantage of being able to imagine what his experience is like，though he probably doesn't think too much about how we see the world.
The environment is the world that all living things share.Living creatures are born into the environment and are part of it.Yet there is no creature who perceives（感知到）all of what is and what happens.For a dog like Sandy a book isn't much different than a stick，whereas for us one stick is pretty much like every other stick.There is no one world experienced by all living creatures.
（1）Why did the author conduct the experiment？
A．To train Sandy to pick out sticks.
B．To show how fast Sandy found sticks.
C．To prove sensitivity of Sandy's nose.
D．To teach Sandy to tell different smells.
（2）What does the author intend to do in paragraph 2？
A．Support the conclusion with numbers.
B．Summarize the previous paragraph.
C．Provide some advice for the readers.
D．Introduce a new topic for discussion.
（3）What does the underlined idiom in paragraph 3 mean？
A．Amazing.
B．Difficult.
C．Reasonable.
D．Inconvenient.
（4）Which of the following best expresses the authors opinion in the last paragraph？
A．Worlds to experience.
B．An environment to share.
C．No environment，no creatures.
D．One environment，many worlds.發(fā)布：2024/12/18 14:30:1組卷：5引用：2難度：0.5
