The communications explosion is on the scale of the rail, automobile or telephone revolution. Very soon you’ll be able to record your entire life (1) —anything a microphone or a camera can sense you’ Il be able to (2) . In particular, the number of images a person captures in a lifetime is set to rise exponentially. The thousand (3) a year I take of my children on a digital camera are all precious to me. (4) a generation’ s time, my children’ s children will have total image documentation of their entire lives—a (5) log of tremendous personal value.By then we’ll be wrestling with another question: how we control all the electronic (6) connected to the internet: trillions of PCs, laptops, cell phones and other gadgets. In Cambridge, we’re already working (7) millimetre-square computing and sensing devices that can be linked to the internet through the radio network. This sort of (8) will expand dramatically (9) microscopic communications devices become dirt-cheap and multiply. Just imagine (10) the paint on the wall could do if it had this sort of communications dust in it: change colour, play music, show movies or even speak to you.(11) costs raise other possibilities too. (12) launching space vehicles is about to become very much cheaper, the number of satellites is likely to go up exponentially. There’ s lots of (13) up there so we could have millions of them. And if you have millions of loworbit satellites, you can establish a (14) communications network that completely does away with towers and masts. If the satellites worked on the cellular principle so you got spatial reuse of frequencies, system (15) would be amazing. Speech is so (16) that I expect voice communication to become almost free eventually: you’ 11 pay just a monthly fixed (17) and be able to make as many calls as you want. By then people will also have fixed links with business (18) , friends and relatives. One day I (19) being able to keep in touch with my family in Poland on a fibreoptic audio-video (20) ; we’ll be able to have a little ceremony at supper-time, open the curtains and sit down "together" to eat. Read the following text. Choose the best word (s) for each numbered blank and mark A, B, C or D on ANSWER SHEET 1.20（）

Few insects have inspired as much fear and hatred as the diminutive fire ants, less than half an inch long but living in colonies of more than 250,000 others. Everyone in the southern United States gets to know fire ants sooner or later by painful experience. Fire ants live in large earthen mounds and are true social insects--that means they have a caste system ( division of labor), with a specialized caste that lays eggs (queen) and a worker caste of sterile females. There are several reasons that they are considered pests. About 60% of people living in areas where fire ants occur are stung every year. Of these, about 1% have some degree of allergic reaction ( called anaphylaxis) to the sting. Their large mounds are unsightly and can damage mowing equipment. Fire ants sometimes enter electrical and mechanical equipment and can short out switches or chew through insulation. Finally. as fire ants move into new areas, they reduce diversity of native ants and prey on larger animals such as ground-nesting birds and turtles.Even though fire ants are pests in many circumstances, they can actually be beneficial in others. There is evidence that their predatory activities can reduce the numbers of some other important pests. In cotton, for example, they prey on important pests that eat cotton plants such as bollworms and budworms. In Louisiana sugarcane, an insect called the sugarcane borer used to be a very important pest before fire ants arrived and began preying on it. Fire ants also prey on ticks and fleas.Whether fire ants are considered pest or not depend on where they are found, but one thing is sure—we had best get used to living with them. Eradication attempts in the 1960s and 1970s failed for a number of reasons, and scientists generally agree that complete elimination of fire ants from the United States is not possible. A new, long-term approach to reducing fire ant populations Involves classical biological control. When fire ants were accidentally brought to the United States, most of their parasites and diseases were not. Classical biological control involves identifying parasites and diseases specific to fire ants in South America, testing them to be sure that they don ’ t attack or infect native plants or animals and establishing them in the Introduced fire ant population In the United States. Since fire ants are about 5 to 7 times more abundant here than in South America, scientists hope to reduce their numbers using this approach. Which of the following is a reason why fire ants are considered pests（）
