26、Let me tell you something about sharks. Sharks are among the oldest animals in the world. There are over three hundred fifty different kinds of sharks in the world. Most sharks are about two meters long and live in the oceans.
A shark can smell something in the water, for example, the blood of animals. That helps them find their food. Sharks mainly eat fish, other sharks and plants in the ocean.
Most sharks bite people by mistake. They think a person is a large sea animal. When the sun goes down or comes up, sharks are looking for food. So at these times people shouldn’t go swimming in the ocean.
There is a huge need for shark fins (鳍) in Asian countries. As a result, many sharks are caught and killed. According to reports, sharks are being killed at an shocking rate (速度) of up to 273 million worldwide every year.
Some experts predict that if the killing continues at the current rate, many shark species will be lost forever. It can be very dangerous. Sharks are very important and they should be protected.
【1】How many kinds of sharks are there in the world?
A．Less than 350.
B．More than 350.
C．About 200.
D．Over 400.
【2】What do sharks mainly eat in the ocean?
A．Fish, other sharks and plants.
B．Fish and plants.
C．Other sharks and plants.
D．Fish and other sharks.
【3】Why do most sharks bite people by mistake?
A．Because they think a person is dangerous.
B．Because they think a person is a large sea animal.
C．Because they think a person can hurt them.
D．Because they think a person can take away their food.
【4】Why shouldn’t people go swimming in the ocean when the sun goes down or comes up?
A．Sharks are everywhere at those times.
B．Water is cold then.
C．Sharks are looking for food then.
D．Sharks are looking for a person then.
27、Climate change could turn the Arctic Ocean into a high-speed ice superhighway. Large pieces of sea ice in the Arctic Ocean are becoming thinner as old ice melts. The new ice that's replacing it travels farther and faster than the older ice does. As the new ice travels, it carries dirt, organisms and pollution along for the ride, new research shows.
Researchers have been tracking the movements of Arctic ice for several years. They noticed that the area covered by ice making the trip from one side of ocean to the other has grown larger and larger. The movement means that far-away reaches of the Arctic are becoming more connected, notes Robert Newton, from Columbia University.
The speedy ice is a problem, he explains. The reason: It increases the risk of spreading pollution from some environmental disasters, such as oil spills. An oil spill during the summer could become trapped in this autumn ice. The ice could then quickly move from one country's waters to another's, he notes, rapidly spreading the spill's impact on the environment.
Between when it forms and melts, the ice can get pushed across the Arctic Ocean by winds and ocean currents. These forces more easily pushed young, thin ice along than old ice. Newton and colleagues wondered what the impact would be on these ice rafts and the pollution they held. Less ice could mean less space to carry a large load of pollutants. But a less crowed Arctic might let the ice travel farther and faster.
In the study, the researchers put together pictures of the Arctic, which came from satellites far above the surface. They used the computer software that can recognize the edges of sea ice. This allowed them to follow the movements of the ice from formation to melting. To help them do that, they also included tracking buoys on the ice that had been equipped with GPS devices.
About 60% of Arctic ice travels less than 100 kilometers from its birthplace, they found. The rest covers an area equal to tens of thousands of square kilometers. It can travel hundreds or even thousands of kilometers. And that ice is moving faster as well.
【1】What does the text focus on?
A．Climate change is becoming more serious.
B．The Arctic ice travels fast and carries pollution.
C．It's difficult to follow the movements of the ice.
D．The Arctic is likely to be covered by the ice.

B．It is much easier to pollute than before.
C．It results in more environmental disasters.

【3】Why did the researchers study pictures of the Arctic taken by satellites?
A．To find out how far the ice can go.
B．To make it clear how the ice comes into being.
C．To learn about the original situation of the Arctic.
D．To see how a moving ice connects itself with another.
【4】What does the underlined word "that" in paragraph 5 refer to?
A．Using computer software.
B．Taking photos of the Arctic.
C．Keeping track of ice.
D．Collecting pictures through satellites.

29、 With the summer heat becoming increasingly unbearable over the years due to climate change, the cooling load in the summertime has also been on the rise. Insulation (隔热)is currently the main solution for blocking heat from entering a building, but by applying an additional material that can delay heat penetration(渗透),it can prevent the indoor temperature from rising and in turn lower the cooling load of the building.
A research team in Korea has developed a new material for building walls that can help reduce the penetration of heat from the outside. The team directed by Dr. Sarng Woo Karng from KIST revealed that they have successfully done it through building walls by applying a phase change material (PCM). One of the most common types is paraffin oil, which is used to make candles.
A solid PCM absorbs heat as it transitions into liquid phase, so by using a case to hold it when it is in liquid phase without causing any leakage (渗漏)，it is possible to apply them to a building wall to block heat from entering inside.
The problem, however, is that the PCM turns into liquid starting from the outermost layer, and the parts that are hot move upward, while the parts that are still relatively cool move downward. Thus, while the upper part may have completely melted, the lower part will have not, and as a result, heat will penetrate into the building through the area where the PCM is in liquid phase. In the end, the PCM becomes ineffective in controlling the indoor temperature and is rendered useless.
Dr. Karng's team addressed the non-uniform phase change with bubble injections. By injecting bubbles into the bottom part of the PCM enabled uniform circulation (流动)of the PCM in liquid phase. Dr. Karng said, “We expect that the insulating wall using the PCM bubble generator used in this study will contribute to reducing the amount of energy used to heat or cool a building. Insulation techniques using the PCM help reduce heat penetration, in combination with the building insulating material, and it can also be used as the outer walls of zero-energy buildings.
【1】What kind of function do PC Ms serve according to the text?
A.Lowering heat penetration. B.Making the walls stronger.
C.Being used to make candles. D.Perfecting the building walls.
【2】Why is a case used when the PCM is in liquid phase?
A.To test its effect. B.To avoid the risks.
C.To block the heat. D.To stay in shape.
【3】What is the problem when PCMs turn into liquid phase from the solid one?
A.They'll cause heat leakage. B.They'll lower heat penetration.
C.They don't melt evenly. D.They're hard to operate.
【4】What can we infer about insulation techniques using PCMs?
A.They are imperfect. B.They are ineffective.
C.They are low-cost. D.They are environmentally-friendly.
