A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater
We all have to learn how to stop wasting our limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done in this field.
Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying factory. There it can be filtered and treated with chemicals so that it can be used again, just as it were fresh from a spring.
But even if every large city purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we’d have to do to make use of the seawater on earth is to get rid of the salt.
This process is called desalinization, and it is already in use in many parts of the world.
The way to stop wasting our limited water is to ().
A.do experiments with water
B.purify the used water and reuse it
C.use fresh water once again
D.make use of seawater
The two most common kinds of logic or reasoning are inductive and deductive.
Inductive reasoning is mainly scientific and factual it begins with collected data,experiments. and examples.When enough information has been colleted,a statement of aprinciple is taken from the examples.
Deductive reasoning begins with a general principle and applies it to a specifie instance or specific instances The conclusions of deduetive thinkers are more tentative than the conclusions of inductive thinkers, who arrive at a principle instead of starting from one.Deductive thinkers are accurate only to the extent that their principle is correct and only to the extent that they have applied it truly.
Both inductive thinking and deductive thinking are tested. and questioned by those to whom the conclusions are presented. Of an inductive thinker,one asks whether the facts are true. whether the exceptions have been noted, whether the selection of materials is representative. whether the conclusions are truly and accurately drawn from the data,whether the conclusions are stated precisely or exaggerated(夸大的). Of a deductive thinker, one asks whether the given principle is impartial truth or mere personal opinion,whether it is applied to materials relevantly,whether the conclusion is accurate according to the principie, and whether exceptions have been noted.
With good motives and bad, with bonesty and with deceit. different thinkers teach different conclusions derived from the same data or from the same principle. What is the difference between inductive thinking and deductive thinking?
A.Inductive thinking starts from data, experiments and examples and then arrives at a principle,while deductive thinking starts only from data
B.Inductive thinking starts from a principle,and then applies it to a specifie instance or specific instances, while deductive thinking starts from data experiments and examples and then arrives at a principle
C.Inductive thinking starts from data, experiments and examples and then arrives at a principle,while deductive thinking starts from a general principle,and then applies it to a specific instance or specific instances
D.Inductive thinking starts from data and then applies them to specific instances,while deduetive thinking starts from experiments and then appliesthem to specific instances
Which one of the following should an inductive thinker pay attention to?A.Whether the general principle is impartial truth or mere personal opinion.
B.Whether he is honest or not.
C.Whether the facts are true or not
D.Whether the general principle is applied to material relevantly.
The common concern for inductive thinkers and deductive thinkers is___A.whether the exceptions have been noticed
B.whether they are bearing good motives or not
C.whether the conclusions are derived from the same data
D.whether they starts from the same general principle
Which statement among the following is true?A.Deductive thinking is mainly scientific and factual
B.The deductive thinkers will never be accurate
C.Both inductive thinking and deductive thinking are tested and questioned by those to whom the conclusions are presented
