2 . The giant Amazon rainforest in South America has been a mystery for centuries. It holds all kinds of natural wonders. Among them in Colombia, a river stands out as “the most beautiful river” in the world.
Locally called Carnio Cristales, this special river lies in a national park. It is made up of several waterfalls, rapids, and plenty of pools. For most of the year, Canio Cristales looks like a common river: clean, green, and rocky. However, during the short period between September and November, the river explodes (迸发) with life and colour. It appears as any mix of colours including blue, green, yellow, orange, and a purplish red. So it is also known as the “River of Five Colours”.
Although at first it may appear as if some chemicals were added to the water, this rainbow river is completely natural. Cafio Cristales' colours are the result of a rare (稀有) water plant which needs sunlight to grow. The plants change colour depending on how much sunlight they receive, and the amount is decided by the height and speed of the water. Therefore, it is possible for the plants to be totally colourless if the sunlight is too hard to get. They are a delicate plant. This makes them easily damaged in the water.
Actually, the river faces some problems, including drier seasons, wildlife trouble, waste management, and budget (预算) cuts. In 2007, the park was forced to close because it was over-crowded with tourists. Now the park admits only 200 people a day and requires them to mind their behaviour.
Today, Cano Cristales still shines among Colombia's most popular natural attractions, drawing thousands of tourists every year.

4 . Long lines at security checkpoints, tiny plastic cups of drink, small bags of biscuit, planes full of passengers, fees attached to every service—all reflect the realities of 21st century commercial air travel. It’s no wonder that many travelers have become nostalgic (怀旧) for the so-called “golden age” of air travel in the United States.
During the 1950s, airlines promoted commercial air travel; airline hostesses served full meals on real china, airline seats were large and frequently empty with enough legroom, and passengers were always dressed well.
After jets were introduced in the late 1950s, passengers could travel to even the most distant locations at speeds unimaginable a decade before. An airline trip from New York to London that could take up to 15 hours in the early 1950s could be made in less than seven hours by the early 1960s.
But the good memory of airline in that time can be tricky, and “golden ages” are seldom as beautiful as they seem. Until the introduction of jets in 1958, most of the nation’s commercial planes were propeller-driven (螺旋桨驱动) aircraft. Most of these planes were unpressurized, and with a maximum cruising (巡航) altitude of 10,000 to 12,000 feet, they were unable to fly over bad weather. Delays were frequent, turbulence (气流) was common, and air sickness bags were often needed. For much of this period, the old saying “Time to spare, go by air” still rang true.
Through the 1930s and into the 1940s, almost everyone flew first class. Airlines did encourage more people to fly in the 1950s and 1960s by introducing coach or tourist fares, but the savings were relative: less expensive than first class, but still pricey. Although the invention of jets did result in lower fares, the cost was still out of reach of most Americans.

6 . Most people hate mosquitoes — but scientists are about to build a “mosquito factory” to release modified (改良的) mosquitoes.
The modified mosquitoes carry a bacterium called Wolbachia pipientis (沃尔巴克氏菌), which can be naturally found in most insect species. However, it’s rarely discovered in mosquitoes. “We actually grow these mosquitoes that contain the bacterium,” Scott O’Neill, an Australian scientist involved in the project, told CBC News. When the modified mosquitoes are released, they slowly spread the bacterium to the population.
Several studies have demonstrated the insects’ success. For example, a controlled experiment in Indonesia showed that the modified insect helped reduce the cases of the disease dengue (登革热) by 77 percent, according to a study paper published in 2021.
The World Mosquito Program has announced that it will release modified mosquitoes in many of Brazil’s urban areas over the next 10 years. The aim is to protect up to 70 million people from diseases such as dengue, an infectious disease mainly spread by mosquitoes.
Brazil has one of the highest rates of dengue infection in the world, according to the Nature website. “More than 1,000 people died of dengue in 2022 because of the spread of mosquitoes. It’s going everywhere,” Luciano Moreira, a scientist in Rio de Janeiro, Brazil, told CBC News.
Another way to prevent mosquitoes from spreading diseases is by producing genetically modified mosquitoes (GM). In 2022, the US Environmental Protection Agency cleared the release of 2.4 billion GM mosquitoes in California and Florida.
According to the agency, GM mosquitoes carry two types of genes: a self-limiting gene that prevents female offspring (后代) from surviving to adulthood; and a marker gene that allows researchers to identify GM ones in the wild. After being released, GM mosquitoes lay eggs, so the genes are passed on to offspring. In this way, the number of female mosquitoes is reduced, therefore reducing the chance of spreading disease.
1. What is the final purpose of building the “mosquito factory”?A.To prevent the spread of mosquito-borne diseases. |
B.To produce massive mosquitoes for scientific research. |
C.To study the behavior of mosquitoes in different environments. |
D.To replace the natural mosquito population with a modified one. |

9 . English is English, right? Not exactly. Although Americans share the same language as those in Great Britain, words that commonly mean one thing in America can mean something completely different in Britain. Here are some examples.
In the United States a bird is, well, an animal with feathers. In England, however, a bird is often used to describe a young female, similar to the way young women are referred to “chicks” in America. But be careful when you are calling your boss’ daughter a bird, because some Britons consider the word a negative expression.
Saying you need a new trainer in America means something quite different from it does in England. In the US, trainers are healthy and strong experts who can help you work out. However, in England, trainers are just another name for tennis shoes.
In America, the word “jumper” usually means a call to 911, as it can refer to a person who’s trying to jump from a bridge or building. The meaning couldn’t be more different in Great Britain, where “jumper” is the name given to a knit top, or, as it’s called in America:a sweater.
Telling a Londoner that you like to sleep with your comforter every night may cause some strange looks, unless you’re a baby. In the US, a comforter is a cover for bed that is filled with a soft material, but in England, a comforter is a word used to describe a baby’s pacifier (橡皮奶嘴).
In America, a casket, also called a coffin (棺材), clearly has a sad meaning. In Great Britain, on the other hand, a casket has a completely different meaning:it refers to a small box used to store jewelry or other valuable objects.
If a Londoner tells an American he locked something in his boot, the American may look at him strangely. In America, a boot is a type of footwear, while in England the word is used to refer to a trunk (后备箱) of a car.
