No one can foretell the future of technology exactly, because no one can see the future. However, there are reasonable     1     (argue) based on the advances and trends in technology in the past. For example, it’s reasonable to predict that computers will continue to become more powerful, numerous and cheaper. Areas with huge potential,     2     are just beginning to be made use of today, like biotechnology, will continue to produce fruit.

Technology in general will probably continue to improve,     3     (create) both promises and risks. In     4     area of computers, someone might interact with hundreds of embedded microchips (嵌入式微芯片) throughout the home and the office. In the future, it will be many thousands.     5     some have called “ubiquitous computing” —— computers everywhere helping us with everything —— will be caused by increasing bandwidth and decreasing costs. Some viewers, especially Bill Gates, believe the next few decades     6     (characterize) by long-awaited revolutions in robotic technology. Other futurists see trends in automation technology leading to desktop factories that enable users     7     (make) objects from a host of simple     8     (origin) parts.

Apart from above areas, there are dozens if not hundreds of areas that will continue to advance technologically. One thing is     9     sure: the future will have better technology than the past did. But will we put     10     to better use? Only time and effort will tell.

Gene editing has a wide     3    (apply) across the world. It can     4     (direct) change the DNA of a lifeform and has the potential of leading to     5    (benefit) results.

One of the most convenient methods of gene editing is called CRISPR/Cas9,     6     was discovered by the two Nobel winners.

During the repair process, errors will be introduced to create a different sequence of DNA, thus resulting in an     8    (edit) gene.

In simple words, CRISPR/Cas9 is the “scissors” of genes. The greatness of CRISPR/Cas9 lies in extreme accuracy. It also enables humans to breed (孕有) more plant varieties and develop better treatment of cancer.

Ships of several nations spot a(n)     1     (mystery) sea monster, which is considered to be a giant narwhal (独角鲸). The US government gathers an expedition (探险队) in New York to find and destroy the monster. Professor Pierre Aronnax, a French marine biologist (海洋生物学家),     2     happens to be in New York at the time, receives a last-minute     3     (invite) to join the expedition, which he accepts. Canadian whaler Ned Land and Aronnax’s     4     (faith) servant Conseil are also brought aboard.

The ship finds the monster after a long search and then attacks the beast,     5     damages the ship’s rudder (舵). The three people then jump into the water and grasp the “hide of the creature”, which they find, to their surprise, to be a submarine (潜艇) very far ahead of its time. They are quickly captured (俘获) and brought inside the submarine, where they meet its     6     (create) and commander, Captain Nemo.

The rest of the story follows the adventures of the people aboard the submarine, the Nautilus,     7     (build) in secrecy and now roams (漫游) the seas free from any land-based government. Nemo explains that his submarine is     8     (electric) powered. They visit many places under the ocean; some are real-life places, others are fictional. The travelers also use diving suits to hunt sharks and other marine life with air-guns and have an underwater funeral (葬礼) for a crew member who dies     9     an accident occurs under unknown conditions inside the Nautilus.

The tale of Shangri-La is among the most interesting myths. Not     1     (surprise), then, modern people have been drawn to the dreamland     2     the ruin of time and history has been held back, human beings live in harmony with nature, and the wisdom of the planet is saved for future     3     (generation).

Lost Horizon was a tale for    4     (it) times. The story of Shangri-La itself is a modern one, told by the English novelist James Hilton in his novel Lost Horizon (1933). Set in the troubled years before World War Two, the book tells of a community in a lamasery (喇嘛庙), in the lost Tibetan valley of Shangri-La, cut off from the world and from time. All the wisdom of the human race     5     (contain) in this place, in the stored cultural treasures, and in the minds of the people       6     have gathered here in the face of the war.

In the 1930s,     9     Western civilisation seemed bent on a path to self-destruction — and when, as Carl Jung put it, “the smell of burning was in the air” — the story had a great charm. And Tibet in the 1930s was still a land of mystery, one of the last unmapped places. Nowadays, of course, the choice of the location of the tale seems more     10     (attract).
