题目内容
Much to his surprise,he invited only twenty friends to the dinner,but____ came.
- A.twice as many as
- B.as many as twice
- C.twice as many
- D.twice more than
C
试题分析:考查倍数表达。倍数表达有四种:1. “A+倍数+形容词或副词的比较级+than+B”, 2.“A+倍数+as+形容词或副词的原级+as+B”, 3. “A+倍数+the size/height/length/width, etc+of+B”, 4. “……times+what从句”。以上的4种情况中,倍数都要放在最前面,故B错误;more than是修饰twice的,要放在twice的前面。故D项错误。本题中提及的是名词friends,故使用many修饰。A项的第二个as是多余的。故C正确。
考点:考查倍数表达法
点评:倍数表达是高考常考内容,倍数表达要牢记,倍数表达法是高中英语教学的重点,当我们要表达甲是乙的几倍时,通常用句型来表示:1. “A+倍数+形容词或副词的比较+than+B”,表示“A比B大(长、高、宽等)多少倍”。如:This rope is twice longer than that one. 2.“A+倍数+as+形容词或副词的原级+as+B”,表示“A正好是B的多少倍”。如:Asia is four times as large as Europe. 亚洲的面积是欧洲的四倍。3“A++the size/height/length/width, etc+of+B”,表示“A正好是B的多少倍”。如:This street is four times the length of that one.4.“……times+what+从句”。如The production is now three times what it was ten years ago.

QUESTION: Dear Marie, Do you have some good suggestions of biology: plant, animal, human science experiments that would work well with teenagers? Scientific methods must go with the experiments. Thanks! < Donna ANSWER: Dear Donna, Marie is not online and I’ll help you instead of him. There are a lot of little things that can be done, but do you mean lab experiment or statistical analysis, etc.? Let us know what can be suitable for you teens, and we will do our best to send you some experiments to do. Best, Gloria |

QUESTION: Dear Gloria, I need lab experiments. The teenage students and I will use data from these experiments to make charts, graphs, tables, etc. and to provide claims and evidence to explain more about the results. Thank you very much. Donna ANSWER: Hi there, Your best and easiest way is to do some chemistry experiments. Those are very easy and most probably you can do it in the lab and have charts, etc. for you. I do not have any particular one at the top of my head because I do cancer research and it is a bit more difficult than research for teenagers. I think you can look through these and see if you find something useful for you. http://www.siraze.net/chemistry/sezennur/experiments.htm If not, get back to me and Marie, and we’ll look more. The good thing about this site is that it has the procedures that you can follow. Good luck, Gloria |
