It’s never easy to admit the mistakes you make, but doing so is an important step toward moving forward.

National Geographic magazine recently published an article with the title “For decades, our coverage was racist. To rise above our past, we    1     acknowledge it.” It was written by the magazine’s editor-in-chief Susan Goldberg, the first woman and first Jewish person     2    (hold) the position. National Geographic has acknowledged that its coverage of black and minority ethnic people in America and the wider world had been historically racist, frequently promoting caricatures (讽刺画) of the “noble savage (野蛮人)” and barely     3     (feature) the US’s minority ethnic population.

According to Goldberg, the 130-year-old publication’s April issue “explores how race defines, separates, and unites us”. In honor of 50 years since the killing of Martin Luther King,    4     is known for fighting racial inequality in the US, the issue is devoted to race.

The population republished a number of examples of historical racism in its coverage. One 1916 article about Australia included a photo of two Indigenous Australians with the caption: “South Australian Blackfellows: These savages rank     5     (low) in intelligence of all human beings.”

To review its previous coverage of race, Goldberg asked University of Virginia John Edwin Mason to look back at the magazine’s text, choice of subjects, and photograph of people of color from the US and abroad. “Until the 1970s, National Geographic all but ignored people of color who lived in the United States, rarely acknowledging    6     beyond laborers or domestic workers,” Goldberg wrote about Mason’s findings. “Meanwhile, it pictured ‘natives’ elsewhere     7     exotics, famously and frequently unclothed, happy hunters, noble savages.”

Mason also found that the magazine often ran photos of “uncivilized” natives    8     (amaze) by “civilized” Western technology.

In recent years, however, the magazine has improved. For example, in a 2015 project, National Geographic gave cameras to young people in the Caribbean country of Haiti and asked them to shoot pictures of their everyday lives.

“The coverage wasn’t right before     9     it was told from a white American point of view, and I think it speaks to exactly     10     we needed a diversity of storytellers,” Goldberg told the Associated Press.

Can you speak to dolphins (海豚)? Of course you can but you won’t be able to understand them! Here is     1     a biologist has told us:

Just like dogs, cats and other mammals, dolphins communicate using sound, sight, touch and taste. Dolphins don’t have the ability to smell,     2     their hearing and eyesight are excellent. Dolphins have their own language and they start talking to each other from birth.     3     (actual), scientists think dolphins, like people, “talk” to each other about a lot of things, like their age, their     4     (feeling) or finding food. And, like humans, dolphins use a system of sounds and body language     5     (communicate). But understanding their conversations     6     (be) not easy for humans. No one speaks “dolphin” yet, but some scientists are trying to learn.

Dolphins are social animals. They live in groups, and they often join others from different groups to play games and have fun. In fact, playing together is something only     7     (intelligence) animals do.

Dolphins are a great helper for fishermen. When fish are near a boat, dolphins show signs     8     the fishermen.     9     (use) this method, fishermen can catch a lot of fish. And in return, the dolphins     10     (give) some of the fish.

My name is Marly. I’m from an Inuit village in the far north of Canada. Our lives are closely connected with the natural world of the Arctic.

Though we live in     1     (regularly) houses, we stay in temporary shelters called “igloos” when we go hunting. Igloos are made     2     snow or ice. On the one hand, they are quite warm inside and building materials can       3       (find) everywhere. But on the other, they can only be kept for around fifty days.

We get our food from the nearby seal. Eating a lot of fish and meat     4     (keep) our bodies strong so that we can fight the cold. But the downside is that the cold weather makes     5     difficult for us to grow enough vegetables and fruit.

It’s     6     (absolute) dark here for three months of the year,     7    is the period called “the polar night”. So, life can sometimes be boring! But the good thing is. during that time the elders tell us stories about our people. It gives us more time     8     (stay) with our family and friends.

Nowadays, ships bring tourists to the Arctic. The advantage to this is that it brings more money and job     9     (opportunity) . But the disadvantage is that our environment is being polluted.

But one thing is for sure: no matter how things change, our traditions will remain     10     important part of our lives.

Many years ago in a small village, an old man    1     (hire) to clear the spring (泉水) up on the mountain. He patrolled (巡逻) the spring every day, and swept away all the leaves and other things that would dirty the fresh flow of water. Soon, beautiful swans (天鹅) came to the clear spring and with time     2     (go) on, the village became a popular    3     (attract) for visitors.

Years passed. One evening the town leaders thought     4     unnecessary to keep this old man on year after year and so the old man was asked to leave.

For several weeks, nothing changed. By early autumn, the leaves began to fall     5     the trees, and the spring was covered with leaves. A few days later, the water was much     6    (dark). Only a few months after the old man left, all the swans left, as did the tourists. Disease reached deeply into the village.

Quickly, the leaders held a special meeting. Realizing their decision to fire the man was not     7    (reason), they rehired the old man. Since then, the village     8    (enjoy) great popularity among the tourist.

So,     9     your work or your life seems to be small, never overlook it. Anything we can do will make     10    difference
