Have you ever bought something just because the salesman talked you into it? Are you afraid to ask someone for a date?Many people are afraid to assert themselves(堅(jiān)持己見)．Dr．Robert Alberti，author of Stand Up, Speak Out，and Talk Back, thinks it’s because of their lack of confidence．“Our structure of organization tends to make people distrust themselves．”says Alberti．“There’s always a‘superior’arounda parent，a teacher，a bosswho‘knows better’．These‘superiors’often gain when they keep breaking at your selfimage．”But Alberti and other scientists are doing something to help people assert themselves．They offer“assertiveness training”coursesAT for short．In the AT course people learn that they have a right to be themselves．They learn to speak out and feel good about doing so．They learn to be aggressive without hurting people．In one way, learning to speak out is to overe fear．A group taking an AT course will help the shy person to lose his fear．But AT uses an even stronger motivethe need to share．The shy person speaks out in the group because he wants to tell how he feels．Whether or not you speak up for yourself depends on your selfimage．If someone you face is more“important”than you，you may feel less of a person．You start to doubt your own good sense．You go by the other person’ s label．But，why should you?AT says you can get to feel good about yourself．And once you do，you can learn to speak out．48．People are reluctant to talk back because____．A．they have a poor selfimageB．they have not received AT coursesC．they have not grasped munication skillsD．they are not generous enough to share things【答案】A【解析】文章最后一段第一句Whether or not you speak up for yourself depends on your selfimage，說明一個人是否愿意把自己的想法大膽的說出來取決于一個人的自我形象。故A正確49．According to Dr．Alberti，our organization is constructed to____．A．get people to trust their own solutions to problems

be“superiors”D．help people overe their fear of asserting themselves【答案】D【解析】49題已經(jīng)講過，此機(jī)購的目的是幫助人們克服恐懼，找回自信。51．Which of the following would be the best title for the passage?A．Protect YourselfB．Try to Speak OutC．Share Your OpinionD．Face Your Superior【答案】B【解析】本篇文章的目的是希望人們大膽的說出自己的想法，克服恐懼的心理，故B正確Passage FiveA wind tunnel is used for testing planes or plane models．In a wind tunnel air is blown over a plane ora model placed in a test section．Wind tunnel test sections are different in size depending on airflow speed requirements．Some lowspeed tunnels have test sections large enough for a plete small plane．In the very high speed tunnels used for space testing，however，the model may be as small as a pencil．There are two ways of feeding air to the test section．In the constant flow tunnel，airflow produced by electric fans is forced through the tunnel to the test section，then through another tunnel section back to the starting point for reuse．The other way involves storing highpressure air in a box，sending it out by a controlling device to pass through the tunnel and test section into another box．This way is usually used for a very short period of highspeed airflow．Wind tunnels are usually used to test planes before they are flown．Problems in a plane carl be found when it meets the highspeed airflow in the tunnel．For example，if the wings are built so that they would weaken at high speeds，this fact can be discovered in the tunnel，thus saving many lives and millions of dollars．In a wind tunnel，scientists also find out how different planes will act at different speeds．They find out such things as how the air dives by the wing surfaces，how slowly a plane can fly before it starts to drop，and howfastit can climb．52．Some wind tunnel sections are larger than others because____．A．they are used for large planesB．they can produce a stronger windC．they are built to conduct a highspeed testD．the air in them flows at a lower speed【答案】D【解析】根據(jù)常理，風(fēng)道面積大，風(fēng)速就慢。D是正確答案。53．The underlined words“this fact”in Paragraph 3 refer to the fact that____．成人高考網(wǎng)

highspeed air flow in the tunnel【答案】B【解析】本句是說如果機(jī)翼劣質(zhì)，高速飛行時會受損。問題中的this fact 指的是機(jī)翼質(zhì)量不好。故B正確。54．As mentioned in the last paragraph，a wind tunnel can be used to find ．how fast a plane can riseB．how smooth a plane’s surface isC．how a plane lands in a strong windD．how a plane drops at a low height【答案】A【解析】這個句子and how fast it can climb．說明A是正確答案。55．What can we learn from the passage?A．It is very expensive to build a wind tunnel．B．Wind tunnels are very essential in testing planes．C．Scientists still have a lot to learn about wind tunnels．D．There are new ways to feed air to the test section．【答案】B【解
