2 . In 1845, a deadly disease struck the farms of Ireland, killing all the Lumper potato plants. In another place or time, the death of a single crop species might not have been so important. But in Ireland, in 1845, people depended almost on the potato for food. The death of one species caused a terrible famine. Now, some scientists are worried that such a famine could happen again.
Over the centuries, farmers have discovered thousands of different species of food crops. Some can be grown in very hot or cold climates. Others are not affected by certain diseases. However, you won’t find many of these species in your local supermarket. To feed the seven billion people on Earth, most farmers today are growing only species of plants that are easy to produce in large numbers. Meanwhile, thousands of other species are becoming extinct.
For example, in the Philippines, there were once thousands of varieties of rice; now fewer than 100 are grown there. Experts believe that over the past century, we have allowed more than half of the world’s food varieties to disappear.
One solution to this problem is to collect and store the seeds (种子) of as many different plant varieties as we can before they disappear. The idea was first suggested by Russian scientist Nikolay Vavilov. In the 1920s and 30s, he collected around 400,000 seeds. More recently, others are continuing the work he began.
In the U.S. state of Iowa, Diane Ott Whealy wanted to protect historic plant varieties. She started a place called Heritage Farm, where people can store and trade seeds.
More importantly, the people at Heritage Farm don’t just store the seeds; they plant them. By doing this, they are reintroducing foods into the marketplace that haven’t been grown for years. These food species are not just special in flavor. They also offer farmers food solutions for the future, from the past.

4 . The Mississippi is a romantic river whose relationship with man goes back beyond its discovery by the Spaniards in the 16th century. Indians used the river as a highway and as a source of food, and it was they who gave it its name —''misi'', meaning ''great'' and ''sipi'' meaning ''water''.
When the length of its great tributary (支流), the Missouri, is added to it, the Mississippi becomes the third longest river in the world. From the source of the Missouri to the tip of the delta (三角洲), it is 2,480 miles long. Its head waters have been compared to a healthy, thick-branched tree, healthy because its main branches, or tributaries, are navigable for most of their length.
The Indians paddled up and down the river in their canoes. The first streamer was launched in 1810. It had a single great paddle-wheel at the stern, and was known as a ''paddle-wheeler.'' Throughout the 19th century these unique ships were queens of the Mississippi. They have become part of American history and American literature. The noted writer, Mark Twain, immortalized (使不朽) the river in his greatest novel, Huckleberry Finn, and Oscar Hammerstein immortalized it in his song, Old Man River, which was made popular all over the world by the great black American singer and actor, Paul Robeson.

5 . The great avenues are quiet, and the shops are closed. There’s the smell of fresh bread from a bakery somewhere. It would be hard to say which time of the day in Paris I prefer but this is probably it. Soon the streets will be full of people and traffic. As with most other cities, you see the real Paris when the city wakes up.
There is, however, another part of Paris which is silent and free from people 24 hours a day. Under the city are hundreds of kilometers of abandoned tunnels. During the 19th century, Paris needed more stones for buildings above the ground, so people dug tunnels beneath the city. After that, many farmers grew mushrooms in them. During World War II, the French soldiers also used them. Since the 1970s, many young people have started spending days and nights below the city in these tunnels. It’s now a place for parties, theatre performances, art galleries – anything goes!A “normal” tourist can visit some parts of Paris’s tunnel system, such as the underground cemetery, where you can see the bones of about six million Parisians. The bodies came from cemeteries above the ground two centuries ago when the city needed more space.
However, people are not allowed to enter other parts of the tunnel system. It’s very dangerous because some tunnels might collapse and people will be trapped below. Nevertheless, there are people who will take you to visit them. I have found two “unofficial” tour guides who take me through many tunnels. After a couple of hours we arrive at a room which isn’t on any map. The room is comfortable and clean with a table and chairs and a bed. The guide tells me there are many other places like this. “Many people come down here to party, some people to paint.... We do what we want here.”

The oceans can absorb 93 percent of the heat trapped by the greenhouse gases
“If the ocean wasn’t absorbing as much heat, the surface of the land would heat up much
However, the ocean itself, as Discover Magazine noted, is heating up 40 percent faster on average than the United Nations
7 . Move towards nature when feeling down. Miracles do happen if you try. According to studies, walking among trees makes us relaxed.
For the study, researchers worked with 206 children between the ages of 5 and 15. To measure how connected they were to nature, the kids were asked how much they enjoy activities like seeing wildflowers and wild animals, hearing sounds of nature and touching animals and plants.
So, exposure to nature is related to active behaviors and happiness of children. What does that mean to adults? As we all know, children usually tend to follow adults’, especially their parents’ behaviors. That’s to say, when adults are outside and appreciate nature, kids learn by example.
Researchers say that children need role models who can gently guide them to nature with excitement and an attitude of a lifelong learner.
| A．It’s so adventurous going for a walk around trees. |
| B．Researchers will study more about the connection between children’s performance and nature. |
| C．And if parents enjoy being close to nature, so will their children. |
| D．Parents don’t have to be experts in environmental science or nature studies. |
| E．They found that the kids connected to nature were more likely to behave properly. |
| F．In a new study, researchers wanted to see if kids get the same benefits from being outdoors. |
| G．Even just smelling the trees helps reduce anxiety. |

9 . If the three Rs (reduce, reuse and recycle) is a guideline to save the planet, garbage-sorting is where the efforts start. Since May 1, Beijing has started to carry out mandatory garbage-sorting in new efforts to better protect the environment. Under the new regulation, residents are required to classify household waste into four categories: kitchen, recyclable, hazardous and other waste. People who fail to sort their garbage properly can be fined from 50 to 200 yuan, reported Xinhua.
Some residential communities in Beijing have introduced rewards to encourage residents to sort their garbage. According to Xinhua, residents can earn points by classifying their domestic waste correctly and then exchange the points they accumulate for daily necessities such as soap.
Garbage sorting practices have reached over 70 percent of housing estates in 18 cities, including Shanghai, Xiamen and Hangzhou, according to the Ministry of Housing and Urban-Rural Development. Shanghai first enacted a mandatory garbage-sorting regulation in July 2019 and has had a 90 percent compliance (服从) rate among its housing estates.
According to a report by the Ministry of Ecology and Environment, over 90 percent of the public believe that garbage-sorting is important for the protection of the environment. However, garbage-sorting is still a big problem in China. Only 30 percent of participants said they think they are completely sorting their waste, the report noted. According to Xinhua, it’s partly because many people lack the willingness to sort their own waste. Also, some previous garbage regulations didn’t include fines for people who failed to obey them.
“It’s a must to have a legal guarantee to promote garbage sorting,” Liu Jianguo, a professor from Tsinghua University, told China Daily, “Aside from China, many countries like Germany, Spain and Britain, also ask people to sort waste into specific categories. In Japan, there is a fixed time for the sorting of each kind of garbage and littering.”

10 . When “Rise of the Planet of the Apes” was first shown to the public last month, a group of excited animal activists gathered on Hollywood Boulevard. But they weren’t there to throw red paint on fur-coat-wearing film stars. Instead, one activist, dressed in a full-body monkey suit, had arrived with a sign praising the filmmakers: “Thanks for not using real apes (猿)!”
The creative team behind “Apes” used motion-capture (动作捕捉) technology to create digitalized animals, spending tens of millions of dollars on technology that records an actor’s performance and later processes it with computer graphics to create a final image (图像). In this case, one of a realistic-looking ape.
Yet “Apes” is more exception than the rule. In fact, Hollywood has been hot on live animals lately. One nonprofit organization, which monitors the treatment of animals in filmed entertainment, is keeping tabs on more than 2,000 productions this year. Already, a number of films, including “Water for Elephants,” “The Hangover Part Ⅱ” and “Zookeeper,” have drawn the anger of activists who say the creatures acting in them haven’t been treated properly.
In some cases, it’s not so much the treatment of the animals on set in the studio that has activists worried; it’s the off-set training and living conditions that are raising concerns. And there are questions about the films made outside the States, which sometimes are not monitored as closely as productions filmed in the States.
