  Passage 5
  These is a new type of advitisement becoming increasingly common in newspaper classified columns.It is sometimes placed among"situations vacant",although it doesn't offer anyone job,and sometimes it appears "situations wanted",although it is not placed by someone looking for a job either.What is does is to offer help in applying for a job.

  "Contact us before writing your application", or "Make use of our long experience in preparing your curriculum vitae (工作简历) or job history", is how it is usually expressed.The growth and apparent success of such a specialized service is,of course,a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae(or job histor),with the suggestion that it may now qualify as an art form in its own right.

  There was a time when job seekersimply wrote letters of application." Just put down your name,address,age and whether you have passed any exams", was about the average lavel of advice offered to young people applying for their first jobs when I left school.The letter was really just foropeners, it was explained,everything else could and should be saved for the interview.And in thosedays of full employment the technique worked.The letter proved that you could write and were available for work.Your eager face and intelligent replies did the rest.

  Later, as you moved up the ladder,something slightly more sophisticated was called for.The advice then was to put something in the letter which would distinguish you from the rest.It might be the aggressive approach. "Your search is over.I am the person you are looking for," was a widely used trick that occasionally succeeded.Or it might be some apecial feature specially designed for the job in view.

  There is no doubt,however,that it is the increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.

  The new type of advertisement which is appearing in newspaper columns _____.[ANSWER]
  A)informs job hunters of the opportunities available.
  B)promises useful advice to those looking for employment.
  C)divides available jobs into various types.
  D)informs employers that people are available for work.

  Nowadays a demand for this spacialized type of service has been created because _____.[ANSWER]
  A)there is a lack of jobs available for artistic people.
  B)there are so many top-level job available.
  C)there are so many people out of work.
  D)the job history si considered to be a work of art.

  In the past it was expected that first-job hunters would _____.[ANSWER]
  A)write a initial letter giving their life history.
  B)pass some exams before applying for a job.
  C)have no qualifications other than being able to read and write.
  D)keep any detailed information until they obtained an interview.

  Later, as one went on to apply for more important jobs,one was advised to include in the letter _____.[ANSWER]
  A)something that would attract attention to one's application.
  B)a personal opinion about the organization one was trying to join.
  C)something that would offend the person reading it.
  D)a lie that one could easily get away with telling.

  The job history has become such an important document because _____.[ANSWER]
  A)there has been an increase in the number of jobs advertised.
  B)there has been an increase in the number of applicants with degrees.
  C)jobs are becoming much more complicated nowadays.
  D)the other processes of applying for jobs are more complicated.

  Passage 6
  The accuracy fo scientific observations and calculations is always at the mercy of the scientist's timekeeping methods.For this reason,scientists are interested in devices that given promise of more precise timekeeping.

  In their search for precision,scientists have turned to atomic clocks that depend on various vibrating atoms or molecules to supply their "ticking"(滴答滴答地响).This is possible because each kind of atom or molecule has its own characteristic rate of vibration.The nitrogen atom in ammonia,for example,vitrates or "ticks" 24 billion time a second.

  One such atomic clock is so accurate that it will probably lose no more than a second in 3000 years.It will be of great importance in fields such as astrological observation and long-range navigation.The heart of this Atomichron is a cesium(铯) atom that vibrates 9.2 billion times a second when heated to the temperature of bioling water.

  An atomic colck that operates with an ammonia molecule may be used to check the accuray of the predictions based on Einstein's relativety theories,according to which a clock in motion and a clock at rest should keep time differently.Placed in an orbiting satellite moving at the speed of 18000 miles an hour,the clock could broadcast its time readings to ground station,where they could be compared with a readings on a similar model.Whatever differences develop would be checked against the differe nces predicted.

  The selection say that the accuray of scientific observation depends on _____.[ANSWER]
  A)methods of measurement.
  B)timekeeping methods.
  C)basic assumptions.
  D)earlier experiments.

  Atomic clocks differ according to _____.[ANSWER]
  A)function.
  B)type of molecule or atom used.
  C)rate of vibration.
  D)both B and C.

  From the selection,we may assume that temperature changes _____.[ANSWER]
  A)affect only ammonia molecules.
  B)may affect the vibration rate of atoms.
  C)affect the speed at which the atoms travel.
  D)do not affect atoms in any way.

  Identical atomic clocks may be used to check _____.[ANSWER]
  A)the effect of outer space on an atomic clock.
  B)the actual speed of an orbting satellite.
  C)the accuracy of predicitons based on theories of relativity.
  D)all of Einstein's theories.

  Implied but not stated: _____.[ANSWER]
  A)Precise timekeeping is essential in science.
  B)Scientists expect to disprove einstein's relativity theories.
  C)Atomic clocks will be important in space flight.
  D)The rate of vibration of an atom never varies.

  An appropriate title for this selectiom would be _____.[ANSWER]
  A)A Peacetime Use of the Atom.
  B)Atoms and Molecules.
  C)The Satellite Timekeepers.
  D)The Role of the Clock.
