Hamlet is the most     1     of William Shakespeare’s plays. While you read this article, somewhere there is an actor on a stage pouring out his heart to the audience.

The character of Hamlet has a personal, painful quality that still draws readers and playgoers today as it did 400 years ago. The problems he faces, such as what is     2    and how he should respond to events, are ones we all face in our lives.

Hamlet is the young prince of Denmark. At the beginning, he is sad about his dead father. Everyone else around him is     3     the marriage of his mother Gertrude to her brother-in-law Claudius, the new king. Hamlet thinks that the short time between the death of his father and the marriage of his mother and uncle is     4     .

Hamlet is told that a spirit has been walking around Elsinore castle. He meets it and it says that his father was killed, and by his brother Claudius — it was “murder most horrid (可怕的)”! Now, the ghost instructs him, it is his     5     to avenge (报仇).

Hamlet is in a terrible position. He does not know whether the ghost is who he says he is, or a being sent by the devil (魔鬼). Matters are     6     because Claudius is suspicious of his nephew. There is a cat-and-mouse game played between the king and Hamlet.

Hamlet has a play performed for the king which stages the way the ghost told him of his father’s murder. Claudius reacts with horror, proving to hamlet that he is     7    . But Hamlet misses the opportunity to take his revenge.

He tells Gertrude he hates her     8     to Claudius. During their meeting he kills Polonius, who is the father of his love, Ophelia. Then, Lacerates comes back to the court. He’s heard that his father, Polonius, has been killed, so he wants to kill Hamlet.

Cunning (奸诈的) Claudius attempts to play Lacerates and Hamlet against each other, and in the final scene it all goes horribly wrong.

One     9     speech in the play begins “to be or not to be”: it is about how Hamlet can’t decide whether to get out of his bad situation by killing himself. Hamlet is a thinking man. One who thinks too much in the world where others, like Claudius, show no     10    .

Throughout the 20th century, Japanese towns and cities grew     1    . Today about 80 percent of the Japanese people live in urban areas. The growth of towns and cities, called urbanization (城市化), happens in two ways. One way is     2     rural-urban migration, when people move to the city from the country. As cities prosper and grow, industries and services that     3     many people both as workers and consumers grow to meet the     4     of the increasing population. New industries and services emerge to support the growing business, and the region experiences an upward spiral of growth.

The urban areas on the Japanese island of Honshu (本州岛) continue to grow     5     they attract more people, industries and business. These urban areas contain nearly two-thirds of Japan’s population and manufacturing. City suburbs are     6     in the rural spaces between the towns and cities, and Japan’s efficient and fast transportation system links them all.

Four     7     cities on Honshu-Tokyo Kawasaki (川崎), Chiba (千叶), and Yokohama (横滨) have grown together into one of Japan’s largest urban areas. Two other large urban areas have     8     on Honshu. The area around the city of Nagoya (名古屋) forms one, and the cities of Osaka (大阪)，Kyoto and Kobe (神户) from the other. At the     9     time, these three areas are growing toward one another to form one long, enormous urban area. A single urban system this large is called a megalopolis. This Japanese megalopolis on Honshu, stretching from Tokyo in the east     10     the way to Kobe in the west, is called the Tokaido (东海道) megalopolis.

The Internet has made our lives more convenient. We can get the most     1    information from large     2    , downloading software, documents, and images whenever we need them. What’s more, people’s lives has been changed by online communities and social     3    . A 50-year-old English teacher, sticking at home with only her computer to keep her company because of a serious illness, joined an online group and realized the greatest     4     of the Internet. She believes that it is highly important to bridge the digital divide and make sure that everyone has     5     to the Internet and knows how to use new technology.

Construction of the world’s largest radio astronomy observatory, the Square Kilometre Array, has    1    begun in Australia after three decades in development.

A huge intergovernmental effort, the SKA has been hailed as one of the biggest scientific projects of this century. It will enable scientists to look back to early in the history of the universe when the first stars and galaxies were     2    .

It will also be used to     3    dark energy and why the universe is expanding, and to       4    search for extraterrestrial life.

The SKA will       5     involve two telescope arrays — one on Wajarri country in remote Western Australia, called SKA-Low, comprising 131,072 tree-like antennas. SKA-Low is so named for its sensitivity to low-frequency radio signals. It will be eight times as sensitive than existing comparable telescopes and will     6    the sky 135 times faster.

A second array of 197 traditional dishes, SKA-Mid, will be built in South Africa’s Karoo region.

Dr Sarah Pearce, SKA-Low’s director, said the observatory would define “the next fifty years for radio astronomy, charting the birth and death of galaxies, searching for new types of gravitational waves and expanding the    7    of what we know about the universe”.

She added: “The SKA telescopes will be sensitive enough to detect an airport radar on a planet circling a star tens of light years away, so may even answer the biggest question of all: are we alone in the universe?”

The SKA has been described by scientists as a gamechanger and a major milestone in astronomy research.

“To put the sensitivity of the SKA into     8    , it could detect a mobile phone in the pocket of an astronaut on Mars, 225m kilometres away,” said Dr Danny Price, a senior postdoctoral fellow at the Curtin Institute of Radio Astronomy. “More excitingly, if there are intelligent     9     on nearby stars with technology similar to ours, the SKA could detect the aggregate ‘leakage’ radiation from their radio and telecommunication networks — the first telescope sensitive enough to achieve this feat.”

Prof Alan Duffy, director of the space technology and industry institute at the Swinburne University of Technology, said the SKA would probably be the largest telescope     10    , “connecting across continents to create a world-spanning facility allowing us to see essentially across the entire observable universe”.

If you see a house cat, the    1    are high that it will have white paws, a look that many owners affectionately call“socks.” But socks are rarely seen in wildcats, the elusive and undomesticated cousin of the house cat, so why do so many pet cats sport furry white feet?

As it turns out, this story started about 10,000 years ago, when humans and cats     2       life was better together.

This    3    eventually led to uber-prevalent socks on cats, as well as other well-known coat patterns, said Leslie Lyons, professor emerita and head of the Feline Genetics Laboratory at the University of Missouri College of Veterinary Medicine.

“As humans became farmers and started staying in one place, they had grain stores and waste piles” that attracted rodents, Lyons said. It was a mutually beneficial arrangement: the humans had fewer rodents to deal with and the cats got an easy meal.

The wild, undomesticated ancestor species of house cats, Felis silvestris, lives in Africa and Eurasia. These felines are tasty snacks as kittens and stealthy predators as adults, so     4     born with a coat that offers camouflage (保护色) have tended to survive and reproduce.

But not every F. silvestiis is born with a coat that blends into its habitat.

“Genetic mutations are occurring all the time.” Lyons said.

There isn’t much evidence to indicate why early cat people chose the individuals they did, but Lyons said the range of coats seen on modern domestic cats shows that our agrarian ancestors favored cats with markings that would have     5    with their camouflage.

In its native mixed forest or scrub desert environment, a cat with stark white paws would have stood out to predators and prey.

When humans started taking an interest in cats, these white paws would have stood out to them, too. “There were probably people saying, ‘I particularly like that kitten because it has white feet . Let’s make sure it survives’”, Lyons said.

Humans probably also    6    cats who were calm and comfortable around humans, Lyons said. Behavioral traits seem unrelated to coat color, but for reasons that scientists don’t fully understand, white spots tend to appear when the     7    individuals are selected and bred.

These    8    fur colors and markings emerge while a cat embryo is developing. The cells that give cat fur its color first appear as neural crest cells, which are located along what will become the back, Lyons said.

Then, those cells slowly migrate down and around the body. If those waves of cells move far enough to meet each other on the cat’s front side, the embryo will be born a solid-colored kitten, such as an all-black or all-orange cat. Felines     9    white feet, faces, chests and bellies when these cells don’t quite make it all the way.

So, the next time you see a kitty wearing white socks, you’ll know that this     10     feature is a result of genetic mutations, domestication and developmental biology. Although if you try telling the cat that, it will probably just look at you quizzically before sauntering away.
