| 第1题：The small size of the components of computer chips has proved unstoppable. In each new (1) , those components are smaller and more tightly packed than they were in their predecessor. (2) has been so rapid that chip designers are (3) apparently fundamental barriers to further reductions in size and increases in density. In a small size version of the (4) to wireless communication in the macroscopic world, a group of researchers led byAlain Nogaret, think they can make chips (5) components talk to each other wirelessly. The researchers (6) to use the standard print techniques employed in chipmaking to coat a semiconductor with tiny magnets. These magnets will (7) local magnetic fields that point in opposite directions at different points (8) the chip’s surface.Electrons have a (9) called spin--that is affected by magnetic fields, and the team hopes to use a/an (10) called inverse electron-spin vibration to make electrons (11) the chip emit microwaves. Dr. Nogaret imagine great advances that would stem (12) the success of his work, and these are not (13) to the possibility of packing components yet more tightly. In today’s chips, the failure of a single connection can put the whole circuit out of (14) . This should not happen with a wireless system (15) it could be programmed to re-route signals. The project will not be (16) sailing. Generating microwaves powerful enough to (17) data reliably will (18) involve stacking several layers of magnets and semiconductors together and encouraging the electrons in them to move in a harmonious union.But if it (19) , a whole new wireless world will be (20) .

| 第5题：When lab rats sleep, their brains revisit the maze they navigated during the day, according to a new study (1) yesterday, offering some of the strongest evidence (2) that animals do indeed dream.Experiments with sleeping rats found that cells in the animals’ brains fire in a distinctive pattern (3) the pattern that occurs when they are (4) and trying to learn their way around a maze. Based on the results, the researchers concluded the rats were dreaming about the maze, (5) reviewing what they had learned while awake to (6) the memories. Researchers have long known that animals go (7) the same types of sleep phases that people do, including rapid-eye-movement (REM) sleep, which is when people dream.But (8) the occasional twitching, growling or barking that any dog owner has (9) in his or her sleeping pet, there’s been (10) direct evidence that animals (11) . If animals dream, it suggests they might have more (12) mental functions than had been (13) . "We have as humans felt that this (14) of memory—our ability to recall sequences of experiences—was something that was (15) human," Wilson saiD、"The fact that we see this in rodents (16) suggest they can evaluate their experience in a significant way.Animals may be (17) about more than we had previously considereD、" The findings also provide new support for a leading theory for (18) humans sleep—to solidify new learning. "People are now really nailing down the fact that the brain during sleep is (19) its activity at least for the time immediately before sleep and almost undoubtedly using that review to (20) or integrate those memories into more usable forms," said an assistant professor of psychiatry at Harvard Medical School.
