【正文】 stic to be in the great outdoors，to be mnong so many books and authors，and to get some very good deals，too．”The idea for the festival occurred years ago，but nobody knew if it would succeed．Although book festivals were already popular in other US cities，would Los Angeles residents wele one?“The citizens of the city are very unpredictable，”said one of the festival founders．44．The underlined sentence in the first paragraph implies that____．A．city libraries have a very limited number of readers B．only a small proportion of the readers go to libraries by carC．city libraries provide fewer places for Car washesD．city libraries have fewer parking places45．The outdoor book festival attracts____．A．a(chǎn)utograph seekers and authors onlyB．people with different interestsC．people who love Los AngelesD．people who like cooking46．At the very beginning，people were____ about the idea for the book festival in Los ．confidentB．pessimistic C．uncertainD．indifferent47．The success of Los Angeles book festival shows that____．A．book reading is still popular in Los Angeles B．Los Angeles people prefer library to book festivalC．people attend the book festivals for fun not for reading D．libraries should have food courts to attract more readersPassage FourHave you ever been afraid to talk back when you were treated unfairly? 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 selfimage B．they have not received AT coursesC．they have not grasped munication skillsD．they are not generous enough to share things49．According to Dr．Alberti，our organization is constructed to____．A．get people to trust their own solutions to problemsB．keep people as knowledgeable as their“superiors”C．train people? s capacity to speak up for their righD．make things more favorable for“superiors”50．One of the objectives of AT courses is to____．A．train people to trust othersB．encourage people to share their thoughtsC．tell people of their right to be“superiors”D．help people overe their fear of asserting themselves51．Which of the following would be the best title for the passage?A．Protect YourselfB．Try to Speak Out C．Share Your OpinionD．Face Your SuperiorPassage 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第 ３頁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 speed53．The underlined words“this fact”in Paragraph 3 refer to the fact that____．A．it costs a lot to test a plane B．the wings are not good enough C．some problems are found with a plane D．the wings meet the highspeed air flow in the tunnel54．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 height55．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．【V．D
