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.

Experts have started working on    1     unbelievable project to make a robot made by NASA act like a human.

    2    (name) Valkyrie, the robot looks like a woman and may be used to explorer Mars one day. It       3     (invent) by NASA scientists to compete in the DARPA Robotics Challenges(DRC). It is 1.9 meters tall and    4     (weight) 125 kilograms. It comes with a series    5     cameras, sonar, and other sensors spread across its body to help it move around.

Valkyrie is powered by a battery on its back, which can keep it     6     (operate) for an hour. It can walk on    7       (it) own, pick up objects and control many objects and tools,    8    is part of the requirements for the DARPA challenge.

The machine can walk on two legs and perform basic    9     (move) at present. However, the team from Scotland’s Edinburgh University wants to give it       10     (many) skills. It is hoped that the new and improved robot will work along with astronauts in space.

4 . Traffic is a very important part in daily life.Nearly everyone complains about being stuck in traffic so much     1    people are making it possible that the future city will have no traffic at all.H.G Wells,in his book.The Sleeper Awakes,tells something about the traffic.In the streets of that future London there will be no vehicles.The city    2     (provide) with moving roads.One side of the road travels    3    one direction;    4    other side moves the opposite way. Anyone who wants to go to another part of the city steps on the moving “way” and sits on one of the seats until he arrives.He has none of the troubles,    5    a private car brings with it: whether there is enough petrol,whether the tyres are all right,and where to park it.The moving way is always at his service,always moving    6    (silent) along,always ready    7    (take) him to his destination.That city of the future will have no traffic jams.

To link up the    8    (vary) cities,vehicles driven by atomic power will pass along highways    9    (divide) into two main groups of lanes.Each group will consist of several lanes.Some for slow traffic,some for fast.Crossroads will not exist on these highways,but will be replaced by bridges and junctions.Where these highways enter cities,    10     (port) and other built-up areas,they will pass through underground tunnels.
