2 . From goldfish to sharks, fish of all sizes have lived on Earth for hundreds of millions of years. But do they ever get thirsty?
The answer is yes! Some fish do, at least. But there is a big difference between fish that live in saltwater and ones that live in freshwater.
Bony fish have some salt concentration（含盐量）in their bodies. For bony fish in saltwater, their concentration is lower than the water they live in. Through osmosis（渗透作用）these fish will lose lots of water through their bodies. In order to make up for this loss, they drink lots of water, so it’s easy to say that they can be thirsty. Although drinking saltwater is never a good idea for humans, fish can drink it because they can get rid of the salt through their gills（鳃）.
But sharks are an exception. Sharks can make their salt concentration match the water around them. They do this by building up urea（尿素）in their blood, so they probably don’t get very thirsty. But blood with a high salt concentration can also be bad. The high concentration means sharks won’t do very well in freshwater—water can enter the sharks’ bodies by osmosis and even cause them to explode!
Freshwater fish, on the other hand, are unlikely to become thirsty. Because they live in a less salty environment, they have a different problem: water goes inwards and dilutes（冲淡）their blood. Freshwater fish therefore need to get rid of this extra water. So now we know that saltwater fish can become thirsty and drink water, while freshwater fish will avoid drinking but pee（小便）a lot.

| C．Fish drink saltwater when they get thirsty. |
| D．Fish are different in terms of whether they get thirsty. |

4 . 
The C919 is an important kind of plane in China. 130 lucky people experienced its first business flight(飞行) from Shanghai to Beijing on May 28th, 2023. The body of this plane is painted “全球首架” in Chinese and “THE WORLD’ S FIRST C919” in English. There are 156 seats in the economy class(经济舱) and 8 seats in the first class(头等舱). Twenty big screens are in it, too. The seats are the most comfortable and the screens are the clearest. Passengers can enjoy different kinds of delicious foods. They can also lie down easily and have a good rest because it is very spacious.
The first successful business flight of the C919 makes a big difference to China. We have made great progress in Chinese civil transportation.

6 . Fifteen volunteers have come out a difficult situation from a cave (洞穴) in the southwest of France after spending 40 days without clocks, phones, or sunlight for a human isolation experiment. The group had no communication with the outside world and was not able to use any electronic devices.
Eight men and seven women were grouped to live in the cave as part of a $ 1.4 million project called Deep Time, which set out to explore the limits of human ability to gradually change their behaviour and attitudes in the new situation. The experiment ended after 40 days.
During their time in the cave, the volunteers slept in tents and made their own electricity with a bike since there was no natural light. They also got water from a well (井) 146 feet below the earth. Since there was no sunlight, the team had to follow their biological clocks to know when to sleep, eat, or do daily tasks. To no one’s surprise, they quickly lost their sense of time.
One of the volunteers said he thought he had been underground for 23 days. Another volunteer said he ran 10-kilometer circles in the cave to stay fit. And he couldn’t wait to leave the cave. But other volunteers felt differently, with two-thirds saying they wanted to stay in the cave for longer. Some even thought it was as if they could press pause and stop to live.
During their time in the cave, scientists carefully watched and checked the volunteers including their sleeping patterns, social activities and cognitive functions (认知功能). The experiment will help scientists understand how human brains can help people adapt (适应) to serious living conditions in new situations.

7 . Facial recognition technology(人脸识别技术) is widely used today. For example, police use it to search for bad guys(家伙). It’s also used to unlock phones or doors.
Now, a similar technology, known as facial detection(探测), is entering a new field: the business of advertising.
Such systems are going through tests in a small number of stores. One facial detection system can tell a person’s “happiness” or “fear” level. That helps businesses see how people feel as they look at products or advertisements in the store. Another system can detect whether someone is wearing eyeglasses. If so, stores can send advertisements for new glasses to him.
Facial detection technology is also placed inside some large advertising boards. Cameras in those boards can detect information like people’s ages and five levels of feelings-from “very happy” to “very unhappy”.
Supporters of the technology say it could improve buyers’ experience by showing products they might like or by offering them products at lower prices.
Some are against the idea of using such systems. Pam Dixon, the head of a privacy(隐私) group, is one of them. She thinks the strange actions may cause something unfair. For example, a business could raise the price of a product according to a person’s age and feelings.
However, one store testing the technology explained they wouldn’t store people’s information like names or ages. And the advertising board system maker said it didn’t keep any personal information or record any videos.
1. Facial detection technology can tell people’s ______ according to the passage.| A．weight | B．feelings | C．height | D．jobs |
| A．Businesses. | B．Systems. | C．Customers. | D．Advertisements. |
| A．can detect buyers’ names and record them | B．can’t srore personal information |
| C．may he used to sell cheaper goods in all stores | D．may need some time before being widely used. |
A． | B． | C． | D． |
| A．facial recognition technology entering a new field |
| B．facial recognition technology looking for bad guys |
| C．facial detection technology going into advertising field |
| D．facial detection technology improving buyers’ experience |
In many countries, people are encouraged to buy electric cars. It is said that driving an electric car is good for the environment. But is that true? The University of Minnesota recently studied emissions (排放物) from different cars. The scientists found that sometimes, electric cars are more harmful than petrol (汽油) cars.
Surprising? Well, please pay attention to the word “sometimes”. Electric cars are supposed to be clean. The problem lies in the power that is used to charge them. If the power comes from wind or solar energy, electric cars will cause little pollution. However, if the power is produced from coal, they will be very harmful. According to the study, emissions from these cars kill about 3,000 people a year. However, pollution caused by petrol cars only leads to 880 deaths a year.
In fact, sales people are not lying when they say electric cars are clean. However, they are right only when the power used to charge their cars is also clean.
So how clean electric cars are depends on what its electricity comes from. In France, more than half of the power comes from nuclear (核) stations. Electric cars there should be as clean as they are marketed to be. In many developing countries, however, electricity mainly comes from coal. India, for example, depends on coal for 61 percent of its power. Only two percent of electricity comes from nuclear energy. In countries like India electric cars are not clean at all.
1. Why are people in many countries encouraged to buy electric cars? Because they think electric cars2. How are electric cars whose power come from wind or solar energy?
If the power of electric cars comes from wind or solar energy, it will cause
3. How many people may be killed a year by the emissions from the cars whose power is produced by coal?
Emissions from the cars whose power is produced by coal can kill about
4. According to the passage, in which country the electric cars are cleaner than many developing countries?
Electric cars from
5. Where may power of electric cars come from? (至少写出文中提到的两种能源)
