The Future Life on Mars

Compared with the life we     1    (live) on the earth now, the future life on Mars will be     2    (total) different.

Firstly, without pollution on Mars, people will be able to drink cleaner water     3     breathe fresher air, so they will be     4    (health). The food on Mars will be different     5     our food now. People will just take     6    (pill) and drink man-made juice instead of eating bread and meat. Secondly, people will travel back to the earth or to other planets for sightseeing by spaceship. Additionally, there will be no     7    (fix) school and classrooms. Children will just fly to the classroom in the school spaceships. And people won’t work in factories or companies. They can stay at home,     8    (work) with computers. People believe       9    Mars can support life in the future. Nevertheless,     10     will take some years before these dreams come true.

Jane Goodall had wanted     1     (work) with animals in their own environment since she was a child. But this was not easy.     2     she first arrived in Gombe in 1960, it was unusual for     3     woman to live in the forest. However,     4    the help of her mother, she began her work with the chimps, which changed the way     5    people think about chimps. Spending years observing and recording their daily activities, Jane discovered that chimps hunt and eat meat, against what people used to think. She also discovered how chimps communicate     6    each other.     7     (work) with the chimps for years, Jane has argued that wild animals should     8    (leave) in the wild and not used for     9    (entertain) or advertisements. She has achieved everything she wanted to do, but more     10     (important), she has got the world to understand and respect the lives of chimps.

Twelve laureates were awarded a Nobel Prize in 2020. Their achievements are     1     （benefit）to humankind.

Three scientists, Roger Penrose, Reinhard Genzel and Andrea Ghez,     2     helped uncover the details about black holes, shared this year's Nobel Prize in Physics.

Black holes are massive objects whose gravitational field is so strong     3     nothing can escape it, not even light. At their centers, the laws of physics stop making sense.

No question, these objects are mysterious. Fortunately, the full picture gets clearer than before with scientists     4    （ continuous） working on them. Penrose eventually performed mathematical     5    （ calculation） that showed black holes were not just mathematical ideas     6    （ suggest） by

Einstein^’s theory but that they could form in conditions which are likely to exist in the universe. Using the world’s largest telescopes, Genzel and Ghez each lead astronomers who , since the early 1990s,    7    （focus） on a region called Sagittarius A * （人马座 A 星）at the centre of our galaxy. They     8           （ develop） methods to see through the huge clouds of interstellar （星云）gas and dust     9     the centre of the Milky Way. They also improved new techniques,    10    （ devote） themselves to long-term research. Their pioneering work has given us the most convincing evidence of a supermassive black hole at the centre of the Milky Way.

Dogs are often called “man’s best friend” and make ideal pets.     1     most attractive quality of a dog is its faith in its owner. They always greet us when we come home and they will never leave us when we are     2     danger. For example, there was a very sick man and his dog barked and barked until the rescue team     3     (arrive).

Furthermore, dogs are strong animals     4     will protect us. Houses with dogs are considered much     5     (safe) than those with burglar alarms (防盗警报器). Not only will they stop thieves,     6     they will also guard against fire. For example, there was a serious fire and a dog managed     7     (pull) its owner out.

And     8     (final), dogs can be trained by people. Dogs can do a number of things that people can not. For example, they can find drugs, bodies, illegal DVDs and hunt down prisoners with     9     (they) nose. They’re also used to help the elderly and disabled.

To sum up, dogs are really friendly, civilized (文明的) and loyal     10     (partner) .

Twin giant pandas have been born at a breeding (繁殖) center in southwestern China,    1    is a sign of progress for the endangered species as they struggle for survival due to occupation on their land by agriculture    2    industry.

The male and female baby pandas, born on Tuesday at the Qinling Panda Research Center in Shaanxi Province, are the second pair of twins born to    3     (they) mother, Qin Qin. She was also born at the center and    4     (previous) gave birth to twin females in 2020.

Chinese researchers for years have been working    5     (promote) the population of the animals, which reproduce rarely in the wild and rely    6    a diet of bamboo in the    7     (mountain) of southwestern China.

The efforts have paid off, with some captive-bred pandas being released into the wild. The population of wild pandas    8     (increase) over the past few years,    9     (reach) an estimated 1,800. About 500 others live in zoos and reserves, while the    10     (major) live in the mountainous, heavily forested province of Sichuan.

Some theme parks not only make people feel     1     (amaze) but also are educational. Take the Polynesian Cultural Center (PCC) in Hawaii for example. It not only shows visitors the Polynesian way of life but also     2     (protect) their skills and culture for the future. Polynesia is     3     name given to the groups of small islands that are spread about the Pacific Ocean.

The     4     (villager) from many island communities come to the Polynesian island villages to show visitors their styles of dress and different customs. They are the places     5     visitors can learn how the islanders make clothes from bark (树皮) and how the islanders climb very tall trees with their bare feet.

One of the important skills for Polynesians is boat-building. It allows the islanders     6     (explore) all the islands in the Polynesian Triangle.     7     (obvious), they were sea travellers in their history moving     8     island to island. They were     9     (confidence) of finding their way by     10     (use) the smell of the wind, the movements of the fish and seaweed, and the heights and directions of the waves.
