These kinds of fruit do not need any help from an applethey release enough ethylene to ripen themselves.But that does not mean there is no way to get the job done faster.Growers suggest placing the fruit in a fruit bowl or in a paper bag with the top folded over.Keep the fruit at room temperature,out of direct sunlight.Once the fruit is soft enough,either use it or put it in the refrigerator to keep it from getting too ripe.5.Companion planting refers to the idea that A.some crops can grow together to benefit each other.B.some crops have the similar needs of nutrients,soil and water level.C.some plants can damage each other if grown together.D.a good farming method to prevent natural disasters.6.According to the text, cannot grow together.A.beans and potatoesB.tomatoes and watercressC.legumes and corns D.rice and sugarcane7.What is the function of ethylene?A.To improve the quality of fruits.B.To produce a poisonous gas.C.To keep vegetables fresh. D.To make fruits ripe earlier.8.The text is most likely to be taken from .A.a newspaper of medicineB.a magazine of biologyC.a journal of agricultureD.a travel report语篇解读:这篇文章主要介绍了一些农业知识,其中说明了哪些植物可以混栽,哪些植物不能一起种植以及有些植物可以挥发乙烯气体。答案及剖析:5.A细节理解题。由Companion planting is the idea that some kinds of plants can help each other grow.Plants that are compatible together generally have similar needs in terms of nutrients,soil and moisture levels.可知,混栽植物指的是有些植物可以一起种植,彼此受益的观点,选A。6.B细节理解题。由For example,tomatoes do not like wet soil but watercress does,so you would probably want to keep them separated.可知,西红柿和西洋菜不能一起种植,选B。7.D细节理解题。由Ethylene is a plant hormone(激素)that can cause some foods to ripen too quickly.可知,乙烯气体的作用是让果实早点成熟,选D。8.C推理判断题。这篇文章主要介绍了一些农业知识,所以这篇文章最可能出自农业杂志,选C。.语法填空(2018安徽皖南八校第三次联考)Youth seems to be fading away in my life,only leaving me some unforgettable 1.(memory).Things that we believed would last forever had 2.

(you) life every day!答案及剖析:1.memories考查名词复数。根据前面的“some unforgettable (memory).” some unforgettable 可知,有许多令人难忘的记忆,所以要用复数memories。2.actually考查副词。分析句子结构可知,此处作状语修饰gone,因此要用其副词形式,故用actually。3.which考查非限制性定语从句。分析句子结构可知,此处引导非限制性定语从句,修饰先行词youth,并在定语从句中作主语,故用which。4.until/before/unless考查连词。分析句子可知,是说人在失去某些东西时/之后才会知道忽略了它。故可填until/before/unless。5.have gained考查时态。根据后一句“but also we have lost a lot.”可知,表示已收获了很多的同时也失去了很多,表示动作已完成,故填have gained。6.to achieve考查非谓语动词。It is +形容词+to do sth.,为固定句式,这种句式中的it是形式主语,真正的主语是后面的动词不定式。句意:然而,我们很快意识到要实现它们是很困难的。故本题填to achieve。7.solution考查名词。根据空前的the best可知,此处要用名词形式,故用solve的名词solution。8.be treated考查语态。分析句子结构可知Life与treat之间存在被动关系,所以要用被动语态。而should后要用动词原形,故填(should) be treated。9.the考查冠词。分析 best things可知,形容词最高级前要用定冠词the,故本题填the。10.your考查代词。分析句子If you do not want to have tearing eyes.,hold a positive attitude towards (you) life every day!可知,如果你不想流泪,那就试着微笑,每天积极面对生活。此处修饰名词life,故用形容词性物主代词your。.短文改错(2018山东临朐一中5月模拟检测)Dear Miss Brown,boys and girls,Today we gather here to have a send-off meeting.Our English teacher Miss Brown was going to return to her own country tomorrow.On behalf of all my schoolmates as well as myself I express their hearty thanks to her.In the past two years Miss Brown has taught us writing English.We enjoyed her lessons very much because of her method of teaching was quite different from other.That she gave us in the lessons was both lively and interestingly.With her help,we wouldnt have made rapid pr
