Some (1) by the position of the Sun. Others navigate by the stars. Some use the Sun as (2) guide during the day, and then (3)
2、to star navigation by night. One study shows that the homing pigeon uses the Earths magnetic fields as a guide (4) finding its way home, and there are indications that various other animals, from insects to mollusks (软体动物), can also make (5) of magnetic compasses. (6) is of course very useful for a
3、migrating bird to be able to switch to magnetic compass when clouds cover the sun; (7) it Would just have to land and wait for the Sun to come out again. (8) with the Sun or stars to steer by, the problems of navigation are more complicated (9) they might seem at first. For example, a worker honeybe

5、) to the Sun. (15) the Sun does not stay in one place all day. As the workers start (16) to gather the food, the Sun may (17) have changed its position in the sky somewhat. In later trips during the day, the Sun seems to move farther and farther toward the west. Yet the worker bees seem to have no (
6、18) at all in finding the food source. Their inner (19) tell them just where the Sun will be, and they change their course (20) .（分数：10.00）A.moveB.flyC.steerD.swimA.theirB.itsC.onesD.theirsA.convertB.switchC.plungeD.revolveA.inB.atC.forD.onA.wayB.senseC.useD.advantageA.ThisB.ThatC.WhatD.ItA.otherwis

9、consisted only of members of your own sex. How would you react? Unless there was something definitely wrong with you, you wouldnt be too happy about it, to say the least. It is all the more surprising, therefore, that so many parents in the world choose to impose such abnormal conditions on their ch
10、ildren-conditions which they themselves wouldnt put up with for one minute!Any discussion of this topic is bound to question the aims of education. Stuffing childrens heads full of knowledge is far from being foremost among them. One of the chief aims of education is to equip future citizens with al

Anyone entering adult society after years of segregation can only be in for a shock.A co-educational school offers c
12、hildren nothing less than a true version of society in miniature. Boys and girls are given the opportunity to get to know each other, to learn to live together from their earliest years. They are put in a position where they can compare themselves with each other in terms of academic ability, athlet
13、ic achievement and many of the extra-curricular activities which are part of school life. What a practical advantage it is (to give just a small example) to be able to put on a school play in which the male parts will be taken by boys and the female parts by girls! What nonsense, boys and girls are
14、made to feel that they are a race apart. Rivalry between the sexes is fostered. In a co-educational school, everything falls into its proper place.But perhaps the greatest contribution of co-education is the healthy attitude to life it encourages. Boys dont grow up believing that women are mysteriou

Years of living together at school dispel illusions of this kind. There axe no goddesses with freckles, pigtails, piercing voices and inky fingers. T
16、here are no romantic heroes with knobby knees, dirty fingernails and unkempt hair. The awkward stage of adolescence brings into sharp focus some of the physical and emotional problems involved in growing up. These can better be overcome in a coeducational environment. Segregated schools sometimes pr
17、ovide the right conditions for sexual deviation. This is hardly possible under a co-educational system.

23、 how much of IQ comes from the genes that children inherit from parents and how much comes from experiences, one little fact gets overlooked: no one has identified any genes (other than those that cause retardation) that affect intelligence. So researchers led by Robert Plomin of Londons Institute o
24、f Psychiatry decided to look for some:Plomins colleagues drew blood from two groups of 51 children each. They are all White living in six counties around Cleveland. In one group, the average IQ is 136. In the other group, the average IQ is 103. Isolating the blood cells, the researchers then examine
25、d each childs chromosome 6 (One of the 23 human chromosomes). Of the 37 land marks on chromosome 6that the researchers looked for, one jumped out: a form of gene called IGF2R occurred in twice as many children in high IQ group as in the average grouw-32 percent versus 16 percent. The study concludes
26、 that it is this form of the IGF2R gene, called allele 5, that contributes to intelligence.Plomin cautions that “This is not a genius gene. It is one of many.“ (About half the differences in intelligence between one person and another are thought to reflect different genes, and half reflect differen
27、t life experiences.)The gene accounts for no more than four extra IQ points. And it is neither necessary nor sufficient for high IQ: 23 percent of the average-IQ kids did have it, but 54 percent of genius kids did not.The smart gene is known by the snappy name “insulin like growth factor 2 receptor“
28、 (IGH2R to its fun). It lets hormones like one similar to insulin dock with cells. Although a gene involved with insulin is not the most obvious candidate for an IQ gene, new evidence suggests it might indeed play the role. Sometimes when s hormone docks with the cell, it makes the cell grow; someti
29、mes it makes the cell commit suicide. Both responses could choreograph the development of the brain. Scientists at the National Institutes of Health find that insulin can stimulate nerves to grow. And in rat brains, regions involved in learning and memory are chock full of insulin receptors.Even tho
30、ugh this supports the idea that IGF2R can affect the brain and hence intelligence, some geneticists see major problems with the IQ-gene study. One is the possibility that Plomins group fell for whats called the chopsticks fallacy. Geneticists might think theyve found a gene for chopsticks dexterity,
31、 but all theyve really found is a gene more common in Asians than, say, Africans. Similarly, Plomins IQ gene might simply be one that is more common in groups that emphasize academic achievement. “What if the gene theyve found reflects ethnicity?“ asks geneticist Andrew Feinberg of Johns Hopkins Uni

Con artists and real artists, advertisers and freedom fighters, lovers and sworn enemies-theyve all flocked to email as they would to any new medium of expression. E-mail is convenient, saves time, brings us close
36、r to one another, helps us manage our ever-more-complex lives. Books are written, campaigns conducted; crimes committed-all via e-mail. But it is also inconvenient, wastes our time, isolates us in front of our computers and introduces more complexity into our already too-harried lives. To skeptics,
37、E-mails just the latest chapter in the evolving history of human communication. A snooping husband now discovers his wifes affair by reading her private e-mail-but he could have uncovered the same sin by finding letters a generation ago.Yet E-mail-and all online communication-is in fact something tr
