understand  Chinese        instead        a           important
    active      yourself        give up      enough         anything
How can we practice our spoken English?
    The first and the most (91)important thing is to believe yourself.You should always be full of confidence,or you will never be able to improve your English.You should often encourage.(92)yourselves"Come on,don't be afraid."
    You should never lose heart and never (93)give up.
    Maybe you are afraid of losing face,but you should think since we are students and we are learning,there is no need to worry about (94)anything.You must always be(95)activein practice. There is no problem that your pronunciation and intonation(語(yǔ)調(diào)) can't be as good as the native(本國(guó)的) people because we are(96)Chinese,and we don't have chances to live in foreign 9ountries and talk with the people there. But you must know that the main way to study English is to make ourselves (97)understand other people,You should believe that native speakers will not laugh at you,(98)insteadthey will'encourage you. So if you are brave (99)enough,you will certainly make rapid l:h2Bgress in your spoken English.

7.There are at least two methods.Induction (歸納法) (as described by Darwin ),or deduction (演繹法)( as described by Einstein).Both methods can produce amazing result.But only when you know which"direction"to go.
The steps are the same.They include:
Theory (理論)=Explaining how things work
Experiment=A way to test what's happening
Observation=Something you notice
Together,these are called the scientific method.
Should you start from the"bottom"by collecting information and facts to prove and seeing where chat leads you?That's induction.Charles Darwin (1809-1882 ) supported this method.He spent years observing the appearance and behavior of animals in different places.From this,he created his theory of natural selection:animal and plants can change because of their environment.
Or should you start from the by creating a theory and then seeing how it stands up to real life?That's deduction.Albert Einstein(1879-1955)was king here.He began with brave ideas.These theories often took years to prove by experiment.
A few of Einstein's ideas are still being examined.
In history,scientist have been solving problems using different methods.For example,while studying bacteria(細(xì)菌).Fleming found that something on bread could kill bacteria harmful to human health.This led him to discover a new medicine.Newton suggested that all objects attract each other.His idea was proved later.
So which way better?That depends.Some researchers do experiment,and only later consider where their results may lead them.That's induction.But deduction needs you to suggest a theory that may or may not be supported by the information and facts.The best scientists are always ready to change methods when necessary.
56.How many steps are there in the scientific methodB
A.2
B.3
C.4
57.Deduction needs you to start from theA
A."bottom"

C."lop"
58.Fleming usedAto discover a new medicine.
A.induction
B.deduction
C.theories
59.The last paragraph(段)tells usC
A.which way is better
B.To get more facts
C to use proper methods
60.What can be the best title of the passage?A
A.Deduction and induction
B.Darwin and Fleming
C.Theory and experiment.
