参考答案和解析
正确答案:是由胎盘滋养层细胞分泌产生的一种具有促性腺发育的糖蛋白激素。由α、β两条多肽链组成,其中α多肽链与LH、FSH、TSH的α链相似,而β-多肽链是HCG特有,故用β-HCG的抗体来测定HCG特异性高。HCG主要存在于孕妇的血液、尿液、羊水、初乳和胎儿的体内,主要用于早期妊娠的诊断及滋养层细胞肿瘤的诊断及疗效观察。

      问答题
      when a human infant is born into any community in any part of theworld it has two things in common with any infant, provided neither of them       1._______have been damaged in any way either before or during birth. Firstly, and most     2._______obviously, new born children are completely helpless. Apart from a powerfulcapacity to pay attention to their helplessness by using sound, there is nothing   3._______the new born child can do to ensure his own survival. Without care from someother human being or beings, be it mother, grandmother, or human group, achild is very unlikely to survive. This helplessness of human infants is in markedcontrast with the capacity of many new born animals to get on their feet within   4._______minutes of birth and run with the herd within a few hours. Although younganimals are certainly in risk, sometimes for weeks or even months after birth,    5._______compared with the human infant they very quickly develop the capacity to fend for them.                                    6._______  It is during this very long period in which the human infant is totallydependent on the others that it reveals the second feature which it shares with all 7._______other undamaged human infants, a capacity to learn language. For this reason,biologists now suggest that language be ‘species specific’ to the human race,    8._______that is to say, they consider the human infant to be genetic programmed in       9._______such way that it can acquire language. This suggestion implies that just       10.______as human beings are designed to see three-dimensionally and in colour, and justas they are designed to stand upright rather than to move on all fours, so theyare designed to learn and use language as part of their normal development aswell-formed human beings.

      正确答案:
      1.在any和infant中间加other 在比较两者的异同时,要从比较对象中排除该物或该人。
      2.have改为has 此处主语为neither,故谓语动词要用单数形式。
      3.pay改为draw/call/attract/elicit
      pay attention to注意。此处要表达“吸引注意”的意思。
      4.on改为to
      get to one’s feet起身,站起来。
      5.in risk改为in danger或at risk 这里表达“在危险中,受到威胁”的意思,没有in risk这种搭配。
      6.them改为themselves 这里需要的宾语和主语they都是指代上文的young animals,故要用反身代词。
      7.去掉the
      others指“其他人(物)中的一部分”,the others则指“其他所有的人(物)”。
      8.be改为is 这里suggest意为“提出,暗示”,不作“建议”讲,因此不用虚拟语气。
      9.genetic改为genetically
      genetically用来修饰programmed,“副词+过去分词”相当于一个形容词。
      10.在such和way中加入a 名词way为可数名词单数,前面要用不定冠词。
