Technology is forever changing the way we get our news. Many people now get a lot of their news on electronic devices, instead of traditional media, such as newspapers, television or radio. Now, there is a new way we get the news: computer-created news readers.
Recently, China's Xinhua launched (推出) the world's first AI news presenters with the Chinese search engine Sogou. The news readers created by machine learning technology are based on two real-life newsmen. One is able to present newscasts in English; the other, in Mandarin Chinese.
One Xinhua's report said machine learning was used to examine video images and sounds of the two newsmen, which look and sound like real people.
Some machine learning experts said the system showed off China's latest progress in voice recognition, text-to-speech technology and data analysis. But several experts suggested that the term AI does not correctly describe abilities of the robotic news readers.
On social media, many Chinese noted that the AI presenters did not seem real. People blamed them for not being more lifelike. Others wondered about the effects robots might have on employment and workers. Some people argued that only low-level jobs requiring heavy labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines.
Some businesses have experimented with similar technology for possible use in news operations. Britain's BBC recently released a video that used machine learning to make it look like one of its news readers speaking different languages. The London-based company that developed the system says its goal is to "remove the language barrier" for many different kinds of video across the Internet.
1.What does the author intend to do in Paragraph 1?
A.Introduce the topic of the text.
B.Summarize the different opinions.
C.Add some data about the AI presenters.
D.Compare different ways of getting news
2.What is the machine learning technology used to do?
A.To keep AI presenters from making any mistakes.
B.To make AI presenters speak more fluently.
C.To ensure images and sounds are like real persons.
D.To bring newscasts up to date every hour.
3.What are some people worried about when AI presenters were launched?
A.Robots will eventually replace human all over.
B.Robots may threaten some people's employment.
C.Robots may endanger most people's health.
D.Robots will rule over the world in the end.
4.From the last paragraph we know that______.
A.BBC has removed the language barrier in newscasts
B.BBC's news readers can speak different languages
C.BBC shows interest in Xinhua's AI news presenters
D.BBC has done similar experiments as Xinhua does

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. “We've been going to the same spot in the Pacific Ocean, and we try and characterize longterm change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean.”
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves in the water, or seawater in this case, it forms a weak acid, carbonic acid，” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the PH down, and makes it more acidic.”
The seawater samples Dore and his colleagues have analyzed confirm what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic.”
1.What can be the best title of the passage?
A．Climate Change Affecting Seawater
B．Oceans Becoming More Acidic
C．Sea Life Facing Danger
D．Scientist Researching Seawater
2.With the increase of atmospheric CO2，________.
A．the surface water is becoming warmer
B．more corals will appear in the sea
C．the PH of the ocean out here has been increasing
D．the chemical balance of the seawater is affected
3.Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a．Sea life is endangered.
b．CO2 goes into the surface water.
c．The ocean chemistry is affected.
d．CO2 decreases the PH and makes the seawater more acidic.
e. CO2 levels in the atmosphere go up.
A．a→e→b→c→d B．e→d→c→b→a
C．e→b→c→d→a D．a→b→c→d→e
