Even looking back on the revolutionary changes the Internet has brought to our lives,the future of it is still beyond imagination.But what is clear is making the best use of the Internet will be of ever-greater importance to promoting economic development and social progress.

Already Chinese companies that are seizing the opportunities presented by the Internet occupy a place in global industry.The rise of e-commerce（电子商务）is particularly noticeable in China,where it is common for the majority of young people to do shopping online,which not only saves them time,hut also saves them money.

For the vast rural areas,where the majority of poverty-stricken（穷困的）people live,the growing popularity of Internet technology will hopefully help lift people out of poverty.There have been reports about how some rural villagers sell their agricultural products online and some use the Internet to get in touch with their customers,which may make it easier for them to make decisions.Still they only account for 28.6 percent of the total 618 million internet users nationwide.So much can still be done to further popularize the use of the Internet and promote e-commerce in rural areas.

Looking further ahead,the development of the Internet can strengthen the connection among different economies.No one can tell how much potential there is to be unlocked by the effective use of Internet technology to promote the manufacturing industry（制造业）and the service industry.And with government,it is not just time and cost benefits that are the potential fruits of Internet technology,because the Internet will also help promote policy-making and public services.

1.What does the underlined word "them" in Paragraph 2 refer to?

A. Chinese companies.　　 B. Online stores.

C. Online shoppers.　　 D. Internet users.

2.What does the example of some rural villagers show?

Climate change will bring and has already brought a wide variety of threatening destruction to human existence. Some of these are well-known and already operative, like the wildfires racing along California’s freeways or the permanent droughts that have been upsetting Mediterranean farmers. But are these all terrible disasters we can come up with that are brought about by climate change?

Absolutely not. None of the challenges posed by our warming climate has appeared larger in the popular imagination than sea-level rise, as global populations and wealth are heavily concentrated in low-lying coastal cities. The best available models suggest that 37 million people currently live in places that will be below high tide by 2050-in an optimistic low-carbon-emissions scenario (设想).

Or rather, that’s what such models suggested before this week. On Tuesday, a new study revealed that those alarming statistics were wildly inaccurate. The actual impacts of sea-level rise are going to be much, much worse.

Previous estimates of the impact that rising tides would have on coastal cities relied on essentially a three-dimensional map of Earth obtained from satellite readings. But those readings were fundamentally unreliable because they often measured the planet’s upper surfaces — such as treetops and tall buildings — rather than its ground level. These mistakes led scientists to overestimate the elevation (海拔) of many regions of Earth.

In a new study published by the journal Nature Communications, scientists from Princeton, University detail this methodological problem, then use artificial intelligence to determine the previous literature’s error rate. Their research yields some amazing updates to our conventional understanding of what the next century has in store for our coastlines.

In its optimistic scenario, the Princeton study projects that lands currently occupied by 150 million people will lie below high tide in 2050. But as warming destroys many of the world’s agricultural regions, climate change could accelerate migration from rural areas to coastal cities.

The new study does include one piece of slightly encouraging news. While previous models suggested that 28 million humans currently live in places that already lie below high tide, the actual number is closer to 110 million — which means seawalls and other barriers have proven sufficient to keep many cities dry even as sea levels have risen around them. Still, the scale of barrier construction necessary to save low-lying cities from collapse is now, apparently, far greater than previously understood when the task already looked terribly expensive, particularly for developing countries.

If the Princeton researchers’ projections are correct, avoiding mass death and suffering in the coming decades will require not only rapidly reducing carbon emissions and strengthening construction of seawalls but also furthering mass migrations away from low-lying cities and islands and toward higher ground.

1.The first paragraph is mainly intended to 　　　　 .

A.introduce the topic of this passage

B.show various disasters caused by climate change

C.call on people to fix attention on climate change

D.lay emphasis on the seriousness of climate change

2.All the following statements are true EXCEPT　　　　 .

A.the Princeton study reveals an optimistic picture of sea rising. . .

B.the three-dimensional map produced by satellite is not accurate

C.some measures are mentioned by the writer to deal with sea rising

D.more people are likely to live in coastal cities in the coming years

3.We can see something encouraging from the Princeton study that 　　　　 .

A.it’s cheap to construct seawalls as well as other barriers

B.the scale of barrier construction is much greater than before

C.developed countries have less trouble in dealing with rising sea levels

D.seawalls do have the function to prevent coastal cities being drowned

4.What can be a suitable title for the passage?

A.How to protect cities from rising seas.

B.Rising seas are going to drown more cities.

C.Climate change is endangering human existence.

D.Less emission of carbon, fewer fires and droughts.

One of the most fundamental changes brought about in the last decade is the rise of remote learning. With the global climate crisis and health pandemics, remote learning has become even more relevant today. Schools, universities and corporates can continue affording education and training by remote technology in the time of social distancing due to the COVID-19 crisis. 1.

More importantly, it has also made learning a practical choice for many rural communities who are unable to travel the vast distances to school every day and to remote teams working for companies located afar.

3.

When it comes to learning, one size doesn’t fit all People have varied learning styles that change depending on the nature of the content they are trying to absorb. E-Learning allows learners to personalize their education, focusing on areas that need greater attention in more detail. Also, rather than being a one-way path where the learner listens and takes in information, online training means that learners can pursue areas that interest them in more detail.

Better Engagement

Keeping learners engaged throughout the training is one of the key struggles. One of the strengths of E-Learning is the diverse nature in which the course content is delivered. 4. Some online learning communities allow trainers to provide multimedia recording to make training more engaging. With the game engine, they also have the option to gamify content and include rewards once sections are completed for young employees and fresh graduates who might have just passed out from school and are still transitioning to the corporate world. 5.

A.E-Learning gives people the flexibility to be able to learn at home, anytime they want.

B.Personalized Learning Experience

C.Learn more in detail

D.Learners are now used to and expect interactivity.

E.Nearly 30 percent of learners, or more than six million students, having taken at least one course online.
