根据下列文章,请回答 23～30 题。Teach Your Child Science1 It is important to make your child interested in science from an early agE.Most young children ask a lot of questions and you should give careful scientific answers. Don't only give facts, but try to give explanations as well.2 Science is not just knowledge; it is a way of thinking, a method of finding out about the worlD.We see something. We try to explain it, and we test our idea by setting up an experiment. One day you come home and find the plant on the table has fallen over. You think it might be the wind from the open window or the cat, so you close the window, but leave the cat in and see what happens (you can also try leaving the window open and shutting the cat out). Of course, you remember there may be a third explanation.3 Ask your child to get a piece of string, some salt, a glass of water and an ice cube (冰块). Tell her to put the ice in the water, and then put one end of the string on the ice, leaving the other end over the side of the glass. Put a little salt on the icE.Wait a minute, and then pull the string; it should be attached to the icE.Ask the child: 'What has happened?'4 Probably she won't know. Ask her whether fresh water or salt water freezes into ice first, If you live near the sea and have a cold winter, she should know fresh water freezes first as she will have seen that happen. Show her how to test the idea by half-filling two paper cups with water, adding salt to onE.Then put them in the icebox and check every three minutes, Write the results in a tablE.The conclusion will be that salt changes the behaviour of water. Thinking about the string, we see the salt turned some of the ice into water. Then the salt went away into the water and the ice froze again leaving the string attacheD.5 Then you can ask, 'Will water with salt boil at the same temperature as water without salt?' She can think, tell you her idea and (taking care because of the heat) you can test it in the kitchen.第 23 题 Paragraph 1A.What exactly is science?B.How do you find an explanation?C.What topics do you need?D.How do you answer your child's questions?E.Where does your child study science?F.How do you set up the experiment on salt and water?

根据下列文章,请回答 23～30 题。Robots1 The most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or EuropE.2 Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接),spray-painting and assembling components.3 In Britain, robot sales appropriately peaked in 1984, but have been declining ever sincE.This is partly because British wage rates are too low to make robots financiaiiy attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.4 It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent joB.5 It is estimated that 20% of all comic book heroes in Japan are robots. Tills is an enormous number because comics are so popular that they make up a third of all rnaterial published in Japan.6 The reliability of robots is measured in their M.T.B.F.or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today(equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small samplE.7 The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. Once programmed, the robots can work more accurately and consistently than humans, who can get tired and boreD.第 23 题 Paragraph 2___________A.Ongoing ResearchB.Extension of UseC.Robot HeroesD.Greater ReliabilityE.Falling DemandF.Hidden Danger
