2、代价的技巧练习简直是一味巨毒无比的“五毒散”。培养高效的阅读方法技巧toefl的阅读量非常大，一般的中国考生根本无法把*全部读完，所谓的“扫读法”、“跳读法”和“略读法”也只能适用于少数类型的*，根本不能解决本质问题。那么，*到底应该怎么读法呢?一句话，主动地阅读*的关键部位。所谓主动是指不能象一般的阅读那样完全被动地接受信息，而应该不断的进行思考和预测;所谓关键部位，主要是每一段的开头和结尾部分。由于toefl的阅读理解*全部选自于正式出版物，*的逻辑结构非常完整和严谨，而且出现的逻辑模式也是屈指可数。经过系统的训练，考生的预测可以做到非常准确的程度。这样，通过阅读*的几处关键部位，就能很快

3、地把握整个*的结构和内在的逻辑关系，也就解决了问题的70%。通过训练培养解题思路排除法恐怕是一直以来大多数学生在解阅读理题目时使用最多的方法。事实上，这种方法具有致命的缺点：干扰大、费时间。更有效和迅速的办法是读完题干之后，就在脑子反映出一个模糊的或者是不完整的答案，然后直接在选项中寻找接近的答案进行判断。这种能力必须在平时的训练和讲解中逐渐养成和加强，决非什么技巧之类的东西可以替代。托福阅读理解模拟试题及答案according to some scientists,migratory birds should be able to withstand the winter.a bird s

5、arned.for example,many northern species leave their summer homes while the weather is still warm and the food supply plentiful.young arctic terns born at the arctic breeding grounds will lake off with the flock for distant lands they have never seen.bird migrations are probably regulated by the glan

6、dular system.scientists suspect that the changing length of the day is the factor that triggers migratory behavior.in an experiment,migratory birds were kept in artificially lighted rooms.it was found that if periods of darkness were lengthened proportionately,the glands of the birds became active.t

7、hese glands secrete hormones,which are chemicals that control numerous body functions.shorter periods of daylight seem to change the hormone balance of birds,so that they retain more fat.this stored fat is the fuel that provides the energy for a long flight.the same experiment revealed that the bird

13、答案hormones in the bodyup to the beginning of the twentieth century,the nervous system was thought to control all communication within the body and the resulting integration of behavior.scientists had determined that nerves ran,essentially,on electrical impulses.these impulses were thought to be the

14、engine for thought,emotion,movement,and internal processes such as digestion.however,experiments by william bayliss and ernest starling on the chemical secretin,which is produced in the small intestine when food enters the stomach,eventually challenged that view.from the small intestine,secretin tra

15、vels through the bloodstream to the pancreas.there,it stimulates the release of digestive chemicals.in this fashion,the intestinal cells that produce secretin ultimately regulate the production of different chemicals in a different organ,the pancreas.such a coordination of processes had been thought

16、 to require control by the nervous system;bayliss and starling showed that it could occur through chemicals alone.this discovery spurred starling to coin the term hormone to refer to secretin,taking it from the greek word hormon,meaning“to excite”or“to set in motion.”a hormone is a chemical produced

17、 by one tissue to make things happen elsewhere.as more hormones were discovered,they were categorized,primarily according to the process by which they operated on the body.some glands(which make up the endocrine system)secrete hormones directly into the bloodstream.such glands include the thyroid an

18、d the pituitary.the exocrine system consists of organs and glands that produce substances that are used outside the bloodstream,primarily for digestion.the pancreas is one such organ,although it secretes some chemicals into the blood and thus is also part of the endocrine system.much has been learne

19、d about hormones since their discovery.some play such key roles in regulating bodily processes or behavior that their absence would cause immediate death.the most abundant hormones have effects that are less obviously urgent but can be more far-reaching and difficult to track:they modify moods and a

20、ffect human behavior,even some behavior we normally think of as voluntary.hormonal systems are very intricate.even minute amounts of the right chemicals can suppress appetite,calm aggression,and change the attitude of a parent toward a child.certain hormones accelerate the development of the body,re

21、gulating growth and form;others may even define an individuals personality characteristics.the quantities and proportions of hormones produced change with age,so scientists have given a great deal of study to shifts in the endocrine system over time in the hopes of alleviating ailments associated wi
