3 . 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.

7 . Camels(骆驼) are amazing animals. They aren’t the most beautiful animals in the world. But they are certainly the most useful animals in the hot areas such as North Africa and the Middle East. They usually help people carry things. Now let’s learn more about camels.
There are two kinds of camels on the Earth. They are Arabian(阿拉伯的) camels and Asian camels. Arabian camels are dromedaries(单峰骆驼), but Asian camels are bactrians(双峰骆驼).
An adult camel is about 2 meters tall and about 500 kilograms in weight. Its legs are long. And its feet are big and soft. Most of the camels can live for about 40 years, but they usually stop working when they are about 25.
Camels live alone in the desert(沙漠). They aren’t afraid of the hot and cold weather. Their main food is grass, leaves and bushes. They can walk for more than 600 kilometers and don’t need to drink water. They only need to drink water every six or eight days. But when there is water, they can drink up to 90 liters(升). Camels walk slowly. They don’t like running because it’s too hot. But if they need, they can run at 20 kilometers an hour.

8 . 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.
