Trắc nghiệm Reading Unit 8 Lớp 12 (10 câu)Exercise 1: Read the passage carefully and decide whether statements are True, False or NoinformationWhat happens if, or when, robots are more intelligent than us? If we are going to start to see robotsrunning around with personalities equivalent to human beings, in fifteen or twenty years. It is about timethat we start thinking about that now. These machines are being developed. What will be the ultimateeffect of this? Should they be allowed to make decisions regarding the application of labour force? Whatform and how intimate should human-robot relationships become? Is it a good or bad thing if robotsbecome our natural successors and we fade into extinction?Todays computers operate using transistors, wires and electricity. Future computers might use atoms,fibers and light. A new NASA-developed computing device allows machines to work much like thebrain. This technology may allow fast-thinking machines to make decisions based on what they see. Aplanetary rover might use this technology to avoid obstacles. A spacecraft might use the technology toavoid hazards and identify a pre-selected landing site with very high precision. The device works muchlike the brain, whose power comes from the complex networks of interconnections called synapsesbetween brain cells. Networks of these brain cells, called neurons, allow humans to make instantdecisions based on an observed image or scene.What might the world be like, if computers with the size of molecules become a reality? There will be thetypes of computers that may be everywhere, but never be seen. Bio - computers with very small size willtarget specific areas inside your body. Imagine the ways that billions of tiny, powerful computers willchange our society.Câu 1: In the future, robots will take place of the human labor force.A. TrueB. FalseC. No informationD. All are not correctCâu 2: Human beings will be in danger of extinction due to robots destruction.A. TrueB. FalseC. No informationD. Not givenCâu 3: So far, the scientists from NASA have developed machines, which work in the same way as thebrain.A. TrueB. FalseC. No informationD. Not givenCâu 4: A new NASA-developed computing device can help a spacecraft avoid hazards and identify apre-selected landing site with very high precision.W: www.hoc247.netF: www.facebook.com/hoc247.netT: 098 1821 807Trang | 1Vững vàng nền tảng, Khai sáng tương laiA. TrueB. FalseC. No informationD. Not givenCâu 5: New computers in the future will have such a small size that they cannot be seen.A. TrueB. FalseC. No informationD. Not givenExercise 2: Read the passage carefully and choose the correct answer.In the future, maybe all cars that run on petrol will be replaced by solar cars, which have been around fora while, but with recent developments in solar car design and the measurement of photovoltaic cellsbecoming smaller, the dream of a truly efficient solar car is more reality than fantasy. A solar car is avehicle powered by photovoltaic cells, also called solar cells, which convert sunlight (light energy) intoelectrical energy. As a source of energy on earth, there is nothing like the sun: in a mere one thousandthof one second (.001), the sun emits enough energy to fulfill our planets energy needs for the next 5,000years. It is a staggering fact, and an exciting one. Since the energy from the sun is responsible forrenewable resources such as wind, tides, and heat, solar energy seems to offer the brightest future for notonly cars, but for the entire energy crisis. Despite the appearance that solar energy may be the leastfeasible among the current crop of alternative fuel propositions, new solar powered devices and morespecifically solar powered cars are beginning to be developed. How do Solar. Cars work?The photo-voltaic cells absorb photons from sunlight. This action generates heat, which the cells thenconvert into electrical energy and stores in an on-board battery. This process of conversion is called thephotovoltaic effect. Not surprisingly, such a vehicle has zero emissions, and is very environmentallyfriendly. Unfortunately, at the moment photovoltaic cells are extremely inefficient, yet as time progressesthe efficiency of these cells will grow. This will make solar energy and solar cars the fuel and car of thefuture-a closer reality.Câu 6: According to the text, _______.A. up to now, we have designed some solar carsB. solar cars have been very popular for many yearsC. we have not produced any solar cars yetD. solar cars are not as much appreciated as other kinds of carCâu 7: A solar car is supplied power from _______.A. gasB. petrolC. electricityD. photovoltaic cellsCâu 8: Whi ...
