  By far the most common difficulty in study is simple failure to get down to regular 

concentrated work.This difficulty is much greater for those who do not work to a plan

and have no regular routine of study.Many students muddle along(无计划地进行),

doing a bit of this subject or that,as the mood takes them,or letting their set work pile

up until the last possible moment.

    Few students work to a set timetable.They say that if they did work out a timetable 

for themselves they would not keep to it,or would have to change it frequently,since they can never predict(foresee)from one day to the next what their activities will be.

    No doubt some students take much more kindly to a regular routine than others.There are many who shy There are many who shy away from a self-controlled weekly timetable,and dislike being tied down to a fixed program of work. Many able students state that they work in cycles.Whenthey become interested in a topic they work on it attentively for three or four days at a time.On other days they avoid work completely.It has to be admitted that we do not fully understand the motivation to work.Most people over 25 years of age have become used to a work routine,and the majority of really productive workers set aside regular hours for the more important areas of their work.The "tough-minded" school of workers doesn't fully accept the idea that good work can only be done naturally,under the influence of inspiration.

    Those who believe that they need only work and study as the fit takes them have a mistaken belief either in their own talent or in the value of "freedom".Freedom from control and discipline(纪律)leads to unhappiness rather than to "self-expression" or "personality development".Our society insists on regular habits,timekeeping and punctuality,and whether we like it or not,if we mean to make our way in society,we have to meet its demands.

According to the passage,there are many students who_____.

A．do not like being commanded to study according to a weekly timetable

B．are too timid to accustom themselves to a weekly timetable

C．refuse to exert themselves the whole week as if under military discipline

D．shrink from the self-discipline required for working to a weekly plan

答案 选什么？我上网搜了好久 没找到答案 我看有人选A 是参考书的答案 还是自己想的答案？还有我想选DThere are many who shy away from a self-controlled weekly timetable,and dislike being tied down to a fixed program of work. D选项 shrink from the self-discipline 不就是shy away from a self-cotrolled weekly timetable同义句吗 因为如果选A D为什么错？谢谢！

According to the passage, which of the following is characteristic of lipoproteins?

A．The dangers of lower density lipoproteins and the dangers of higher density lipoproteins are remarkably similar in the case of coronary heart disease.

B．A higher ratio of higher density lipoproteins to lower density lipoproteins has a salubrious effect on heart disease.

C．A shift from a polyunsaturated fat diet to a saturated fat diet tends to increase the risk of coronary heart disease stemming from high-density lipoproteins.

D．A shift from a polyunsaturated fat diet to a saturated fat diet tends to decrease the risk of coronary heart disease stemming from low-density lipoproteins.

E．Controlled feeding studies have yet to establish the feasibility of attempting to manipulate lipoprotein ratios through dietary change.

The world seems increasingly divided into those who favor genetically modified (GM) foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering—which can induce plants to grow in poor soils or to produce more nutritious foods—will soon become an essential tool for helping to feed the world's burgeoning population. Skeptics contend that GM crops could pose unique risks to the environment and to health—risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of GM agricultural products. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards?

Advocates of GM, or transgenic, crops say the plants will benefit the environment by requiring fewer toxic pesticides than conventional crops. But critics fear the potential risks and wonder how big the benefits really are. "We have so many questions about these plants," remarks Guenther Stotzky, a soil microbiologist at New York University. "There's a lot we don't know and need to find out. "

As GM crops multiply in the landscape, unprecedented numbers of researchers have started fanning into the fields to get the missing information. Some of their recent findings are reassuring; others suggest a need for vigilance.

Every year U. S. growers shower crops with an estimated 971 million pounds of pesticides, mostly to kill insects, weeds and fungi. But pesticide residues linger on crops and the surrounding soil, leaching into groundwater, running into streams and getting gobbled up by wildlife. The constant chemical trickle is an old worry for environmentalists.

In the mid-1990s agribusinesses began advertising GM seeds that promised to reduce a farmer's use of toxic pesticides. Today most GM crops—mainly soybean, corn, cotton and canola—contain genes enabling them to either resist insect pests or tolerate weed-killing herbicides. The insect-resistant varieties make their own insecticide, a property meant to reduce the need for chemical sprays. The herbicidetolerant types survive when exposed to broad-spectrum weed killers, potentially allowing farmers to forgo more poisonous chemicals that target specific weed species. Farmers like to limit the use of more hazardous pesticides when they can, but GM crops also hold appeal because they simplify operations (reducing the frequency and complexity of pesticide applications) and, in some cases, increase yields.

But confirming environmental benefit is tricky. Virtually no peer-reviewed papers have addressed such advantages, which would be expected to vary from plant to plant and place to place. Some information is available, however. According to the U. S. Department of Agriculture, farmers who plant herbicidetolerant crops do not necessarily use fewer sprays, but they do apply a more benign mix of chemicals. For instance, those who grow herbicide-tolerant soybeans typically avoid the most noxious weed killer, turning instead to glyphosate herbicides, which are less toxic and degrade more quickly.

Insect-resistant crops also bring mixed benefits. To date, insect resistance has been provided by a gene from the soil bacterium Bacillus thuringiensis (Bt). This gene directs cells to manufacture a crystalline protein that is toxic to certain insects—especially caterpillars and beetles that gnaw on crops—but does not harm other organisms. The toxin gene in different strains of Bacillus, thuringiensis can affect different mixes of insects, so seed makers can select the version that seems best suited to a particular crop.

Defining the environmental risks of GM crops seems even harder than calculating their benefits. At the moment, public attention is most trained on Bt

B．Whether it is healthy to people.

C．Whether it will cause influences on surrounding lives.

D．Whether it is safe.

A.Sharing gossip is always destructive to a work environment.

B.It’s not "Unprofessional" to gossip at work.

C.If a few people know what’s really going on, gossip becomes the means of spreading that information to everyone else.

D.Research show that gossip often reduces individuals’ anxiety and helps them cope with uncertainty.
