ĐỀ THI SỐ 1 ĐỀ THI SỐ 1Question 1: Read the reading passage and then choose thebest answer a,b,c or d. About fifty years ago,plant physiologists set out to grow rootsby themselves in solutions in laboratory flasks.The scientistsfound that the nutrition of isolated roots was quite simple.Theyrequired sugar and usual minerals and vitamins.However,theydid not require organic nitrogen compounds.These roots gotalong fine on mineral inorganic nitrogen. Roots are capable ofmaking their own proteins and other organic compounds.Theseactivities by roots require energy,of course.The process ofrespiration uses sugar to make the high energy compoundATP,which drives the biochemical reactions.Respiration alsorequires oxygen.Highly active roots require a good deal ofoxygen. The study of isolated roots has provided an understanding ofthe relationship between shoots and roots in intact plants.Theleaves of the shoots provide the roots with sugar andvitamins,and the roots provide the shoots with water andminerals.In addition,roots can provide the shoots with organicnitrogen compounds.This comes in handy for the growth ofbuds in the early spring when leaves are not yetfunctioning.Once leaves begin photosyn-thesizing,they produceprotein,but only mature leaves can “export” protein to the restof the plant in the form of amino acids.1,What is the main topic of the passage ?a-The relationship between a plant’s roots and its shoots.b-What can be learned by growing roots in isolation.c-How plants can be grown without roots.d-What elements are necessary for the growth of plants.2,The word “themselves” in line 1 refers toa-plant physiologists b-solutions c-laboratory flasks d-roots3,According to the passage,what is ATP ? a-A biochemicalprocess. b-The tip of a root.c-A chemical compound. d-A type of plant cell.4,The word “intact” in line 10 is closest in meaning to a-mature b-wild c-whole d-tiny5,The use of phrase “comes in handy” in line12 indicates thatthe process isa-useful b-predictable c-necessary d-successful6,It can be inferred from the passage that,in the early spring,thebuds of plantsa- “export” protein in the form of amino acids. b-do notrequire water.c-have begun photosynthesizing. d-obtain organic compoundsfrom the roots.7,Which of the following best describes the organization of thepassage ?a-The results of two experiments are compared.b-A generalization is made and several examples of it are given.c-The findings of an experiment are explained.d-A hypothesis is presented,and several means of proving it aresuggested.Question 2: Rewrite these sentences,beginning as shown.1,You can’t visit the United States unless you get a visa. / Ifyou..........................................2,Henry found a wallet with no name in it. / Thewallet..........................................................3,That rumour about the politician and the construction contractis absolutely false.Thereis...................................................................................................................................4,Susan likes staying in hotels but she prefers camping. / Susandoesn’t............................5,One runner was too exhausted to complete the last lap of therace.One runner wasso..................................................................................................................6,He was sentenced to six months in prison for his part in therobbery.He receiveda..........................................................................................................................7,This affair does not concern you. / This affair isno............................................................8,The hurricane blew the roof off the house. / Thehouse.....................................................9,Tim insisted on being told the complete story. / Nothingbut..............................................10,Skyscrapers in the USA are on average taller than anywhereelse in the world.Theaverage............................................................................................................................Question 3: Choose the best answer a,b,c or d to complete thereading passage below.
