What makes modern science uniquely powerful is its refusal to believe that it already possesses ultimate truth. The reliability of science is based not on certainty but on a complete absence of certainty. As John Stuart Mill wrote in “On Liberty” in 1859, “The beliefs which we have most warrant (依据) for, have no safeguard to rest on, but a standing invitation to the whole world to prove them unfounded.”
......
What is the main idea of paragraph 4?A.It is unwise to believe in science. |
B.Too much uncertainty lies in science. |
C.The foundation of science is unfounded. |
D.The lack of certainty makes science credible. |

Assuming alcohol does enhance the likelihood of a person interacting with someone they find attractive. Bowdring believes her findings could reveal one process supporting the rewarding yet potentially dangerous nature of alcohol - including its impact on risky behaviour.
“If you’re going to consume alcohol, I think it is worth reflecting on how can you do it in a way that’s safe and consistent with your goals,” Bowdring said. “People may benefit by recognizing that valued social motivations and intentions change when drinking, in ways that may be appealing in the short term but possibly harmful in the long term.”
What does Bowdring mainly talk about in the last paragraph?A.The significance of her research. |
B.Reflection on her previous research. |
C.The negative effects of drinking. |
D.Social morality and standards. |
3 . The Yurok people have lived along the Klamath River, which flows from the Cascades in Oregon southwest through Northern California, for thousands of years, protecting the region and river from which they — and others — draw sustenance (生计).
But as development and pollution continue to reduce the number of fish in the river and the quantity and quality of its waters, the Yurok Tribe is legalizing (合法化) the tribe’s longstanding care by granting the Rights of Personhood to the Klamath, the first river in North America to have such rights declared.
......
What is paragraph 2 mainly about?A.The process of legalization. | B.The tradition of Yurok tribe. |
C.The reason behind the legalization. | D.The importance of the Klamath River. |
4 . On March 7, 1907, the English statistician Francis Galton published a paper which illustrated what has come to be known as the “wisdom of crowds” effect. The experiment of estimation he conducted showed that in some cases, the average of a large number of independent estimates could be quite accurate.
This effect capitalizes on the fact that when people make errors, those errors aren’t always the same. Some people will tend to overestimate, and some to underestimate. When enough of these errors are averaged together, they cancel each other out, resulting in a more accurate estimate. If people are similar and tend to make the same errors, then their errors won’t cancel each other out. In more technical terms, the wisdom of crowds requires that people’s estimates be independent. If for whatever reasons, people’s errors become correlated or dependent, the accuracy of the estimate will go down.
What is paragraph 2 of the text mainly about?A.The methods of estimation. | B.The underlying logic of the effect. |
C.The causes of people’s errors. | D.The design of Galton’s experiment. |
5 . Two four-kilometer road tunnels are being built below the central area of the city, one for traffic to the north and the other for the traffic to the south. The two tunnels are about 20 meters below the surface and are 12 meters wide, providing for two lanes of traffic in each direction.
In the upper part of the tunnel, two air conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel. The lighting is at the top of the tunnel, practically at its highest point. There will also be electric signs at frequent intervals. They show traffic conditions ahead and can be seen clearly by drivers. The wall is made up of four main elements, which include a waterproof covering and, on the inside of the tunnel, a concrete lining. Other systems in the tunnel will include emergency phones.
What is the main idea of the passage?
A.The construction of two lanes. | B.The function of a road. |
C.The solution to cars’ pollution. | D.The design of two tunnels. |
What is the main idea of the last paragraph?
A.The world may be more clearly explained through children’s play. |
B.Studying babies’ play may lead to a better understanding of science. |
C.Children may have greater ability to figure out things than scientists. |
D.One’s drive for scientific research may become stronger as he grows. |
7 . But Disney’s story actually started two decades earlier with what Walt Disney called "Daddy’s Day". On Saturdays in the 1930s and 1940s, Disney would take his two daughters to ride the Griffith Park merry-go-round, which they’d enjoy while he sat on a bench dreaming of ways for families to have fun together. Disney disliked the amusement parks they often visited, seeing them as dirty, unimaginative places run by rude employees.
Disneyland opened then. The 5,000 expected guests increased to 28,154, thanks to fake tickets. After the madness of opening day, Disney and his new park were criticized in the press. The media predicted a quick and early end. But the public didn’t listen. Visitors arrived in large groups, and within weeks Disneyland was a success.
Over sixty years later, Disneyland’s popularity continues to grow, with total overall attendance topping 700 million and showing no signs of slowing down.
Which is the best title for the passage?
A.Disneyland: How It All Began | B.Disneyland: An Overnight Success |
C.Disneyland: How It Developed | D.Disneyland: A Park with a Long History |
Which of the following is the best title of the passage?
A.Greenhouse Gas Emission Largely Reduced |
B.Roles of Carbon Sinks Proved by New Study |
C.China’s Forest Carbon Absorption Underestimated |
D.Climate Impacts Balanced Due to China’s Afforestation |
What does the passage mainly concerned with?
A.The measurement of wealth in the current society. |
B.The evolution of people’s attitude towards busyness. |
C.The hidden reasons and effects of people’s busyness. |
D.The solution to prioritizing the crucial tasks in busyness. |
10 . Search engines have changed the way we use the Internet, putting vast sources of information just a few clicks away. But Harvard professor of psychology Line Daniel Wegner’s recent research proves that websites and the Internet are changing much more than technology itself. They are changing the way our memories function.
Wegner’s latest study shows that when people have access to search engines, they remember fewer facts and less information because they know they can rely on “search” as a readily available shortcut.
Which of the following statements can be the best idea of the passage?
A.Relying on technology has weakened our critical thinking. |
B.People heavily depend on computer for storing information. |
C.Human’s capacity for memory is much weaker than it was before. |
D.Computers and technology are reshaping the functions of our brain. |
