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 for a while, but with recent developments in solar car design and the measurement of photovoltaic cells becoming smaller, the dream of a truly efficient solar car is more reality than fantasy A solar car is a vehicle powered by photovoltaic cells, also called solar cells, which convert sunlight (light energy) into electrical energy As a source of energy on earth, there is nothing like the sun: in a mere one thousandth of one second (.001), the sun emits enough energy to fulfill our planet's energy needs for the next 5,000 years It is a staggering fact, and an exciting one Since the energy from the sun is responsible for renewable resources such as wind, tides, and heat, solar energy seems to offer the brightest future for not only cars, but for the entire energy crisis Despite the appearance that solar energy may be the least feasible among the current crop of alternative fuel propositions, new solar powered devices and more specifically 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 then convert into electrical energy and stores in an on-board battery This process of conversion is called the photovoltaic effect Not surprisingly, such a vehicle has zero emissions, and is very environmentally friendly Unfortunately, at the moment photovoltaic cells are extremely inefficient, yet as time progresses the efficiency of these cells will grow This will make solar energy and solar cars the fuel and car of the future-a closer reality
36 According to the text, _ A up to now, we have designed some solar cars
B solar cars have been very popular for many years C we have not produced any solar cars yet
D solar cars are not as much appreciated as other kinds of car
37 A solar car is supplied power from _.
A gas B petrol C photovoltaic cells D electricity
38 Which can not help us to solve the problem of energy crisis?
39 According to the text, _
Trang 3A no powered solar devices have been developed so far
B besides solar car, we have also developed solar powered device
C solar energy plans are more feasible than wind energy plans
D tide can supply more energy than the sun
40 The photovoltaic effect is _.
A the process of operating a solar car C the developing of solar cars and solar powered devices
B the process of absorbing photons from the sun
D the converting of heat from the sun into electricity
