More and more scientific experiments prove that physical exercise can reduce the dangers of some illnesses in middle-aged persons.Exercise strengthens the heart muscle,reduces blood pressure and help to prevent muscles from changing into fat.Physical exercise is just as important for children.
Exercise and food affect growing speed in young lab animals.Baby mice start running as soon as they are big enough to use an exercise wheel in their cage.If they get extra food and run a lot,they will grow as much as 1.5 times bigger than normal.
The same differences in growing speed might be found between active and inactive children.Physical exercise helps active children grow faster than inactive children.One experiment shows that the brains of the mice that had enough exercise weighed about 3%more than those of the mice that did not exercise The mice that exercised are much quicker to learn doing new exercise than the mice that did not exercise.
The results of the experiments suppose the theory that exercise can help babies learn to talk and walk sooner than expected.
The good effects of physical exercise are not limited to children and middle-aged people.Exercise continues to be an important part of our lives after we grow old.For example,people over 50 years old begin to lose calcium(钙) from their bones,which get weaker and can break easily.Physical exercise,however,helps to strengthen the bones and to prevent them from losing calcium.Of course,old people can take medicines to prevent themselves from suffering from losing calcium.But the medicines they take increase the chance of developing some kind of cancer(癌).So physical exercise is a much safer treatment(治疗).
小题1:From the passage we know that .
A.mice need to eat more and exercise more
B.children need more exercise than other people
C.old people like to take medicine to treat their illnesses
D.middle-aged people are easy to get fat
小题2:Active children than inactive children.
A.enjoy walking more
B.are cleverer and healthier
C.are stronger but more foolish
D.are cleverer but weaker
小题3:Why are the bones of old people easy to break according to the passage?
A.Because they are easy to become ill.
B.Because they eat less than other people.
C.Because they have less exercise than other people.
D.there is less calcium in their bones than in those of other people.
小题4:The passage tells people that .
A.only middle-aged persons can benefit from physical exercise
B.physical exercise can do good to both the middle-aged and children
C.people of different ages can all benefit from physical exercise
D.physical exercise is the safest treatment for losing calcium

英语翻译
Since linguistics is the scientific study of language,it ought to base itself upon the systematic,investigation of language data which aims at discovering the true nature of language and its underlying system.To make sense of the data,a linguist usually has conceived some hypotheses about the language structure,to be checked against the observed or observable facts.In order to make his analysis scientific,a linguist is usually guided by four principles:exhaustiveness,consistency,and objectivity.Exhaustiveness means he should gather all the materials relevant to the study and give them an adequate explanation,in spite of the complicatedness.He is to leave no linguistic “stone” unturned.Consistency means there should be no contradiction between different parts of the total statement.Economy means a linguist should pursue brevity in the analysis when it is possible.Objectivity implies that since some people may be subjective in the study,a linguist should be (or sound at least) objective,matter-of-face,faithful to reality,so that his work constitutes part of the linguistics research.

1.It was a good example of the scientific method working the way it is supposed to.
请问这个句子应该怎么划分语法结构,应该怎样理解呢?it is supposed to里的it指代的是什么呢?
答:It 是主语,was谓语,example宾语,of后面的一串都是介词短语.
完整的形式是:It was a good example of the scientific method (which is)working the way (that)it is supposed to.
定语从句的引导词被省略.
the way it is supposed to.的句型类似于:the food we eat=the food that we eat.我们吃的食物.
综上,该句意思是:这是一个很好的科学方法本来就应该的方式来工作的好例子.拗口哈,这样变一下:
此例子很好第诠释了科学方法本来就应该以这样的方式工作
但是该句具体意思还是要结合context综合理解,毕竟句不离段嘛!
2.Was this a failure of science,as some news reports trumpeted?

It includes all normal and abnormal activities of the whole organism,even those of the mentally retarded and mentally ill.
The purpose of this study is to explore the roles of behavior in self-discovery and the varied beneficent behavioral patterns the individual can develop.
The aims of applied psychology are the description ,prediction and control of human activities in order that we may understand and intelligently~direct our own lives and influence the lives of others

整句翻译一下:他们花了很多时间的科学研究证明是有意义、有价值的.
分析一下句子结构:
大体结构是主系表:
主语:
The scientific research( )they had devoted much time
其中()they had devoted much time作为定语从句修饰前面的部分
系动语:turned out,在这里是连系动词;
表语:meaningful and worthwhile.
选择的关键在于devote的用法:
我们知道devote +时间 to sth/sb是固定用法,所以选择D是对的,which在这里只待前面的“The scientific research”,至于C选项“to that”没有这样的用法!

Women have been making scientific discoveries since ancient times.Twelve women have won the Nobel
Prize for science,one of the highest honors in the world.Some women scientists never married,some worked with the ir husbands,and othe rs raised large families.It has been difficult for women to be successful scientists.
In the early 1800s in England,Mary Anning became one of the first women recognized for her discoveries
about the ancient history of the earth.Mary and her fathe r collected fossils (化石) in the ir village on the south
coast of Great Britain.Fossils are parts of plants or animals that have been saved in rocks for millions of years.
When she was only twelve years old,Mary became the first person to find the almost complete skeletons
(骨架) of several animals that no longer existed on earth.She didn't become famous for her discoveries at that
time because she often sold her fossils to get money to support her family.
In 1891,a young Polish woman named Marie Sklodowska traveled to Paris to study physics.She did so
because she could not get a college education in Poland.She began working in the laboratory of a man named
Pierre Curie.Marie and Pierre Curie got married and made many discoveries togethe r.the y received the
Nobel Prize for Physics in 1903 along with anothe r scientist.Marie Curie became the first person to be
awarded a second Nobel Prize in 1911,this time for Chemistry.Marie Curie was one of the few women at the
time who became famous as a scientist.
1.the author believes that women scientists ______.
A.have more opportunities to become successful
B.can not get the highest honors in the world
C.go through difficulties to be successful
D.had better pay more attention to the ir families
2.Mary Anning was one of the first women to ______.
A.win the Nobel Prize for Science after getting married
B.make achievements in the study of ancient Earth
C.research animals and the ir bones
D.study the mystery of all kinds of plants
3.Mary Anning failed to be famous for her discoveries of fossils when she was 12 because ______.
A.nobody recognized the m
B.the y weren't worth studying
C.she didn't want to be known to anyone
D.she sold the m for money
4.What can we learn about Mary Sklodowska?
A.She studied physics in Poland and got a college education.
B.She received the Nobel Prize for Physics in 1903 on her own.

scientific 科学的...形容词,修饰名词,所以explain变名词

这里也是定语从句省略得到的一个定语.
完整的是which was prefered by the...
which was省略掉就成了,不要把prefered 和by分开.
一般比较短的定语可以放到名词前面,比如就一个单词
a building which is ruined
一个破坏了的建筑
也可以说 a ruined building.

英语翻译
We suppose ourselves to possess unqualified scientific knowledge of a thing,as opposed to knowing it in the accidental way in which the sophist knows,when we think that we know the cause on which the fact depends,as the cause of that fact and of no other,and,further,that the fact could not be other than it is.Now that scientific knowing is something of this sort is evident—witnesses both those who falsely claim it and those who actually possess it,since the former merely imagine themselves to be,while the latter are also actually,in the condition described.Consequently the proper object of unqualified scientific knowledge is something which cannot be other than it is.

当我们认为我们在总体上知道:(1)事实由此产生的原因就是那事实的原因,(2)事实不可能是其他样子时,我们就以为我们完全地知道了这个事物,而不是像智者们那样,只具有偶然的知识.显然,知识就是这样子的.在无知识的人和有知识的人中,无知者只是自以为他们达到了上述条件,而有知者则确实是达到了.因而,如果一个事实是纯粹知识的对象,那么,它就不能成为异于自身的他物.
Recently there was a major discovery in the scientific resea
recently there was a major discovery in the scientific research — the mapping of all dna in a human gene(基因) is complete. couple of years ago, this seems an impossible task for scientist to accomplish. all this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. human cloning has always been a topic of argument, in terms of morality(道德) or religion.
taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. if the clone was free of genetic limitations, then the other clone would be as well. the latter could be inserted in the woman and allowed to ripen to term. moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. this surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). it is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the *** of scientists.
arguments against cloning are also on a perfectly practical side. primarily, i believe that cloning would step in the normal “cycle” of life. there would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. life processes failing to do so might result in untimely disappearance. furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
scientists haven’t 100% guaranteed that the first cloned humans will be normal. thus, this could result in introduction of additional limitations in the human “gene-pool”.
regarding such arguable topics in “black or white” approach seems very innocent to me personally. we should rather try to look at all “shades” of it. i believe that cloning is only legal if its purpose is for cloning organs; not humans. then we could regard this as for “saving life” instead of “creating life”. i believe cloning humans is morally and socially unacceptable.
小题1: which of the following is true according to the passage?
a.genetic limitation will be beneficial for some women
b.a large number of genes will prevent us from developing
c.prohibition(禁止) of cloning might limit the *** of scientists
d.first cloned humans might be normal according to scientists

a.cloning should be entirely banned
b.cloning should be used in creating life
c.cloning will take away the right to reproduce
d.cloning is acceptable if it is used for cloning organs
