(1)A robot is a machine that is able to perform a variety of tasks through the use of a computer. (2)This computer is programmed to control movements of the robot's legs, arms, and other appendages by calculations of the various angles through which the robot's joints move. (3)Robots are made ideal for assembly line factory work by these repetitive movements. (4)Some robots are able to handle small parts that fit into small places. (5)Other robots are able to operate tools, such as paint sprayers.

(6)Robots may even be developed with a sense of vision through the use of TV cameras as eyes. (7)Scanning images and calculating sizes and positions of surroundings will help robots to perform many actions in the way that humans do. (8) I want a robot to do my homework.

3one of the biggest impacts a building has on earth is the energy it uses. currently, most of the world’s energy comes from burning fossil fuels. these fuels are dirty and when they are burned they pollute the air and water. one way to burn fewer fossil fuels is to reduce the amount of electricity a building has to use. passive solar heating, which uses heat from the sun, reduces the amount of fossil fuel used to heat buildings. passive solar heating requires a south-facing wall made of glass. when sunlight shines through the wall, it is collected and used to warm the building. another way green buildings reduce their electricity use is to install other energy sources. for example, some green buildings use panels that turn energy from the sun into useable electricity. which is the best summary of paragraph 3? a) fossil fuels are dirty and pollute the air and water. most of the world's energy comes from these fuels. b) the biggest problem of buildings is that they use fuel that is dirty for heating. they need to do something to be more energy efficient. c) panels that turn energy from the sun into electricity and passive solar heating can stop the burning of fossil fuels which pollute air and water. d) since fossil fuels are dirty and pollute the air and water, other technologies that pollute less and produce energy have been developed like solar energy and green buildings.
