High on the Qinghai-Tibet plateau lies China’s “Water tower” Sanjiangyuan.1.The three rivers: the Yellow River, the Yangtze River and Lancang River, provide water for about half the population of China. However, human activities such as overgrazing(过度放牧) are putting this ecosystem at risk.
2.. In 2016, the Chinese government established Sanjiangyuan National Park, which was a pilot(试行) program for China’s national park system.3.Due to the progress made in the region, Qinghai held the first National Park Forum on Aug 19.
Sanjiangyuan National Park is a model of eco-protection.4.For example, Herdsmen have given their grasslands to nature and resettled in urban area. As for wildlife, they are monitored by field conservation stations to keep the environment in good condition.
The idea of a national park system is still new in China, but it must be realized. As President Xi wrote in the congratulatory letter to the forum, “Building an ecological civilization bears great significance in the development and progress of human civilization.” With great efforts，people may one day be able to enjoy themselves in the vast lands of Sanjiangyuan and run freely across the plains alongside nature’s animals.5.
A.Hopefully, though, we have realized the damage.
B.It’s home to the headwater of China’s three big rivers.
C.Unfortunately, the situation has got worse and worse.
D.It attracts visitors with its fantastic nature beauty and various wildlife.
E.The park has increased the area’s green coverage and attracted more wildlife.
F.Hopefully, the success of Sanjiangyuan will mark the start of a greener future.
G.The local government has different ways of slowing environmental degradation.
In 2016, a young British father was trampled（踩踏）to death by an elephant on the island of Koh Samui in ThaiJand. The tragedy once again raised questions over whether it is ethical to use elephants as entertainment.
For many visitors, the chance to interact with elephants is at the top of their holiday wish list. There's no shortage of opportunities to do so, from taking photos of baby elephants to riding them through the jungle, to watching them dance.
But what most visitors don't realize is elephants are involved in extremely cruel methods to make them behave. They are often kept in terrible conditions. This includes being chained up when not performing, without interaction with other elephants, a poor diet, etc. They are also subjected to training practices including beatings. Away from their natural habitat and forced to repeat the same routines day in day out, which continues throughout their dramatically-shortened lives.
Unfortunately, riding elephants is still one of the most popular tourist activities in Asia. The World Animal Protection investigated 3,000 elephants at tourist sites across Southern Asia in 2017. The study found that 77% of them were living in "severely cruel" conditions. It also found that there had been a 30% rise in the number of elephants at tourism venues in Thailand since 2010.
Many parks advertise themselves as sanctuaries (庇护所)but they aren’t. Real sanctuaries will limit contact with the elephants and visitors can only observe them from a distance most of the time.
The government needs to play a much bigger role in putting an end to elephant tourism. As travelers, please avoid any place offering riding or allowing interacting sessions with elephants. When you see abuse happening, do your bit by leaving your review on review sites and social media to warn other tourists. Many parks are now becoming ride-free as a result of pressure from tourists, the industry and the media.

Most of you have heard of the term "big data" by now. When a company records the information of millions of users, it can analyze this "big data" to discover patterns and trends, allowing them to make better business decisions. It sounds like a science experiment, but every single user who gives up their information becomes an unwilling test subject. Companies claim that the data is used to provide "better service".
When shopping on Taobao, for example, you will get product recommendations based on your previous purchases, making it easier to finish a shopping list. However, did you really end up only purchasing items you originally had in mind? Or did you add a few more to the cart as a result of their recommendations? And the customer? They just become one more point of data in the system.
Of course, you might be fine with spending a little extra from time to time, but that is only a tiny droplet (水滴) in the vast sea of big data. Moreover, companies can actually buy and sell your data. So, that is another way for companies to make quick money. The next time a photo editing application asks for your contacts, location and calendar, you may wonder which company is looking to buy your information.
As technology grows more advanced, there will only be more opportunities for you to be exposed. Every single photo, text or video you post on the internet is there to help someone paint a better picture of you. Perhaps in the near future, someone will have collected enough data to predict the future decisions you will make before you even make them. Actually, given the amount of data that is already at their disposal (任意使用 ), maybe it is already happening.
1.What is the purpose of collecting big data for companies?
A.To cut the cost of running companies B.To assist companies get higher profit
C.To provide better service to customers D.To analyze companies’ economic advantages
2.What of the following is the missing sentence in Paragraph3？
A.Big date benefits the customers. B.That’s where the business wins.
C.Taobao dominates the shopping markets. D.Product recommendations make shopping easier.
3.What is the best title for the text?
A.More Data, Less Privacy B.Big Data, Better life
C.More Data, Less Trouble D.Big Data, Future Predictor
