看看母亲育婴方式的一二方面是值得的。一般的爱抚、搂抱和擦洗无需多议，但是她休息时怀抱婴儿的位置却颇堪玩味。美国人的细致研究发现了这一事实：80%的母亲是左手兜住自己的孩子，把孩子放在自己身体的左侧。如果被提请解释这一偏爱的意义时，大多数人会回答说，显然这是人们以右手为主的这种优势造成的结果。母亲用自己的左手抱住婴儿，从而就能腾出自己主要的手臂来从事各种操作。然而一份详细的分析表明情况并非如此。

This brings me to the major cause of unhappiness, which is that most people in America act not on impulse but on some principle, and that principles upon which people act are usually based upon a false psychology and a false ethic. There is a general theory as to what makes for happiness and this theory is false. Life is concerned as a competitive struggle in which happiness consists in getting ahead of your neighbor. The joys which are not competitive are forgotten.

President Clinton, citing “serious ethical questions,” ordered a federal bioethics panel to report in 90 days on whether the United States should regulate human cloning or ban it. Ethicists dusted off arguments they had mothballed in the 1900s, and thousands of trees gave their lives so dueling scholars could publish articles arguing that cloning was a humane way for infertile couples to have a child and joking that cloning made males superfluous.

Australian researchers have discovered electroreceptors (sensory organs designed to respond to electrical field) clustered at the tip of the spiny anteater’s snout. The researchers made this discovery by exposing small areas of the snout to extremely weak electrical field and recording the transmission of resulting nervous activity to the brain. While it is true that tactile receptors, another kind of sensory organ on the anteater’s snout, can also respond to electrical stimuli, such receptors do so only in response to electrical field strengths about 1000 times greater than those known to excite electroreceptors.Having discovered the electroreceptors, researchers are now investigating how anteaters utilize such a sophisticated sensory system. In one behavioral experiment, researchers successfully trained an anteater to distinguish between two troughs of water, one with a weak electrical field and the other with none. Such evidence is consistent with researcher’s hypothesis that anteaters use electroreceptors to detect electrical signals given off by prey; however, researchers as yet have been unable to detect electrical signals emanating from termite mounds, where the favorite food of anteater live. Still, researchers have observed anteaters breaking into a nest of ants at an oblique angle and quickly locating nesting chambers. This ability to quickly locate unseen prey suggests, according to the researchers, that the anteaters were using their electroreceptors to locate the nesting chambers.1. According to the passage, which of the following is a characteristic that distinguishes electroreceptors from tactile receptors?2. Which of the following can be inferred about the experiment described in the first paragraph?3. The author of the passage most probably discusses the function of tactile receptors in the first paragraph in order to ______.4. Which of the following can be inferred about anteaters from the behavioral experiment mentioned in the second paragraph?5. The passage suggests that the researchers mentioned in the second paragraph who observed anteaters break into a nest of ants would most likely agree with which of the following statements?6. Which of the following, if true, would most strengthen the hypothesis mentioned in the second paragraph?
