they are warned first by their friendly plant neighbors.it is not a simple story,and it may be happening in more plant species than tomatoes.it may also be happening with more chemical signals that are still unknown to us.in a word,we know that plants not only communicate,but also look out for one another.11the underlined “traced” in the fourth paragraph probably means _b_ here.areported bfollowedcdoubted ddeveloped12for scientists,which are the right steps to watch tomato plants infested by a pest?_c_place the infested plant upwind.place the uninfested plant downwind.expose the downwind plants to the pest.grow plants in two separate plastic spaces connected by a tube.a bc d13you can put the sentence “the researches also studied leaves from exposed plants and unexposed plants.” at the beginning of _d_.aparagraph 3 bparagraph 4cparagraph 5 dparagraph 614which of the following can be the best title of this passage?_b_acommunicating plants and terrible diseasesbtalking plants and friendly warningscprotecting plants and clear informationdgrowing plants and mysterious chemicalsb(2014,德州)if you want to see a thing well,touching can help you to “see”it better.your eyes can tell you that a glass ball is round.but by holding it in your hands,you can feel how smooth and cool that ball is.you can feel how heavy the glass ball is.when you learn all these about the ball,you really see it well.with your skin,you can feel better.for example,your fingers can tell the difference between two coins in your pocket.you can feel a little drop if water on the back of your hand,too.you can even feel sounds against your skin.have you ever wanted to know why some people like very loud music?they must like to feel the sounds of music.all children soon learn what“dont touch!”means.they hear it often.yet most of us keep on touching things as we grow up.in shops,we touch things that we might buy.to see something well,we have to touch it.the bottoms of our feet can feel things,too.you know this when you walk on warm sand,cool grass or a hard floor.all feel different under your feet.most museums are just for looking.but today some museums have some things to touch.their signs say,“do touch!”there you can feel everything on show.there are ways of learning to see well by feeling.one way is to close your eyes and try to feel everything that is touching your skin.feel the shoes on your feet,the clothes on your body,the air on your skip.if you want to see better,reach out and touch it.then you will really see!15the underlined word“these”in the paragraph 2 refers to(指代)_d_.aa glass ball is roundba glass ball is smooth and coolca glass ball is smooth,cool and heavyda glass ball is round,smooth,cool and heavy16from paragraphs 4 and 5,we can know that_a_.awe have to touch something in order to see it wellbwe never touch things that we might buy in shopscthe bottons of our feet cant feel cool grassdwe can see“do touch!”in all museums17by touching things,you can_c_.ahave a strange feelingbknow how to reach out your handclearn more about themdtell what colors they really are18which of the following is not true?_c_atouching is helping us to see better.bour skin may help us enjoy music.cpeople dont have to learn to feel.dmost people touch things to see them well.19_d_can be the best title of the passage.afeeling by seeingbto see or to feelcways of touchingdto see bettertouch.任务型阅读。(2014,十堰)whats the secret of being a great friend?
