    People often think of the North Pole(北极) and the South Pole as similar frozen(冰冻的) wastelands. They are both places with very cold temperatures and few people live there. However, the North and South Poles are not much alike as people may imagine.

    The North Pole has no land, only thick ice. Temperatures seldom go above 32°F, at which water turns into ice. Most of the time, it stays below zero. In winter temperatures are usually as low as -30°F.

    Although conditions were very poor, people tried for many centuries to reach the North Pole. About 100 years ago, two men, Robert Peary and Mathew Henson, were able to get to this environment full of troubles and difficulties. They reached the North Pole on March 8th, 1909. It was really a hard trip for them.

    There are few things more dangerous than crossing the Arctic(北极圈) on foot. People who stayed there may face many problems: very cold temperatures, sudden storms, and even hunger. Most of the area is uninhabited. Few people can live in such a difficult place.

    People might think that with such low temperatures for most of the year, the ice would be thick and hard. However, this is not true in the Arctic. The movement of the ocean water under the ice may often cause many different changes on the surface. Sometimes the ice breaks into two opening lanes of water(水道) called “leads”. Anyone who falls into a lead can be frozen to death in a few minutes.

One day, you open the fridge and find some moldy (发霉的) food. But before you can throw it away, your mother stops you. She doesn't want to waste it, so she cuts off the moldy part and eats the rest. Is it safe to do this?

Mold can grow on almost all kinds of food. It is usually green, white, black or gray. Mold makes food soft and changes its color. Moldy food tastes quite bad and it's not safe to eat.

If you find mold in soft food, just throw it away. Soft food, such as bread, tomatoes or hot dogs, usually contains(含有) water, which allows mold to grow easily below its surface. Bacteria (细菌)can also grow along with it.

But it's easy to remove mold from hard food because mold can't grow very deep inside this kind of food. According to BBC news, you should cut about 2.5cm around and below the mold to remove it. It's OK to cut the moldy parts out of hard food and eat the rest. But if the food is completely covered with mold, you should still throw it away.

Most kinds of mold are bad for us. But some kinds of mold can be used to make food. For example, penicillin(青霉菌) can be used to make many types of cheeses , such as blue cheese. These cheeses are safe to eat and they're quite delicious as well.

Hello, everyone!

……

That's all. Thank you.

There is a competition for photographers (摄影师) of wildlife in the Natural History Museum in London every year. This year, the competition had about 50,000 photos.These photos come from different parts of the world. They take us underwater, deep into the woods, and high above cities. All of them show different kinds of life on earth.

In the end, the great prize went to Laurent Ballesta. The French photographer won the prize for his photo of a horseshoe crab. In the photo, the horseshoe crab looks for food in the sea. Three little fish follow it closely. They may hope to eat what the horseshoe crab misses.

Horseshoe crabs are known as "living fossils (化石)". They have lived for at least 445 million years and stayed almost unchanged. They're now in great danger, however. What happened to them? In the 1960s, scientists found something surprising. The blue blood of horseshoe crabs can be used for scientific study. As a result, hundreds of thousands of them are caught each year.

For a long time, Ballesta took photos of horseshoe crabs in the sea. His winning photo took the judges (评委) by surprise. "To see a horseshoe crab so alive and well, in such a beautiful way, was fantastic," said one of them.

Read the passage and answer the following questions.

①As the holiday season is coming, shoppers are busy creating their gift lists. Among the usual and popular choices, an unexpected favorite has appeared for a Londoner: China's famous Lao GanMa chili sauce(辣椒酱). Why? It's super tasty, and goes with everything. Besides, it's really cheap.

②Actually, many other Chinese foods has become a craze in the world. In Paris, Guo Jinzhang, a Chinese man, has successfully opened several shops serving daoxiaomian,a traditional dish from Shanxi Province in North China. "Nowadays, many French friends around us have added our noodles to their daily diet," Guo said. "This is our first-hand experience in understanding that food knows no borders."

③In Kuala Lumpur(吉隆坡), a couple of Sichuan restaurants often attract long lines of customers. In Milan, jianbing guozi(a pancake) has become a hot item in Chinatown.

④Chinese food has a long history and a good social foundation (基础). Overseas Chinese include Chinese food and its culture into local food culture. Additionally, international tourists visiting China have experienced Chinese food firsthand. These all make Chinese food popular. In many ways, Chinese food shows the world the rich Chinese culture through taste. When people sitdown for it, they are not just experiencing a meal but a culture.

⑤Therefore, as a bridge between the east and west, Chinese food is sure to go farther.
