Life on planet survives and thrives due to adaptable cloning that occurs over the course of time. Plants can be cloned using various medium, but this article speaks specifically about water as a medium for cloning.Using Water for CloningGrowing plants in water is a very old practice； the Chinese have been doing it for long. Just bear in mind a few of the following stTIF and tips, and you can grow your own plant clone.As old as it may sound, take cuttings from a healthier plant, and use a sharp knife to cut it. Healthier the mother plant, and sharper the cut, better will be the success rate. Cut the stems at an angle of 45， around 1/4 inch below the leaf nodes. Always have a minimum 56 cuttings.To prepare the rooting solution, take a water holder or container, and pour water in it. Threefourth of the jar should be filled.Stand the cuttings individually in different jars, and cover them with transparent plastic sheets while cloning. The plastic covering will ensure high humidity levels, and this, bined with the rooting water, will speed the rooting process. Make sure the water stays clean. Change water after 23 days.The roots will appear in a weeks time. Once you see them, remove the sheet and place them in a location where they can receive partial natural light. Move the rooted cutting to a soil medium once they have enough healthy roots.Cloning of plants in water or through other mediums can ensure existence of species, especially those which are endangered. There are many plants that have one in hundred chances of breeding naturally, or cant produce seeds, so cloning such plants through advance technologies will ensure there continued existence. Cloning plants and trees has helped in better harvest, and increased the plant resistance to harmful viruses and diseases.篇章导读：本文为说明文。大家对于克隆这个概念并不陌生，但是在水中克隆植物也许你并不了解。1According to Paragraph 1, _.Acloning can only be used in all animals and plantsBmany medium can be used to clone plantsCall the livings can clone themselvesDwater is the best medium to clone答案：B细节理解题。根据文章第一段最后一句的“Plants can be cloned using various medium”可知，可用多种媒介来克隆植物。故B项正确。2Why should transparent plastic sheets be used to cover jars?ATo recognize different jars.BTo recognize different cuttings.CTo fasten the rooting process.DTo make the water in jars clean.答案：C细节理解题。根据倒数第三段第二句“The plastic covering will ensure high humidity levels.will speed the rooting process”可知，此举的目的是加快植物生根的速度。故C项正确。3What should you do once you see roots appear?ARemove the sheet in the sun.BMove plants to a soil medium quickly.CChange water for plants more often.DMake them receive some light.答案：D细节理解题。根据倒数第二段第二句中的“place them in a location where they can receive partial natural light”可知，D项正确。4It can be inferred that cloning plants in water _.Ais seldom used in todays agricultureBcan make plants not catch diseasesCcan increase farmers ineDsometimes make specie be endangered答案：C推理判断题。文章倒数第一段提到了水中克隆植物可以使植物更加抗病、高产，因此可推知这样可以增加农民的收入。故C项正确。5What does the passage mainly tell us?AWays to clone plants.BCloning plants in water.CHow to clone animals and plants.DA special way to grow plants.答案：B主旨大意题。文章主要是讲怎样在水中克隆植物，故B项是最佳选项。1adaptable adj. 有适应能力的；能适应的2practice n. 惯常做的事；习惯3individually adv. 分别地；单独地4breed v. 交配繁殖；饲养5resistance n. 抵抗；抗拒；反对1over the course of time 在期间；在的时候2bear in mind 将记在心中；记住Bxx河西区高三质检People may use the expression “birdbrain” in English to talk about someone who is stupid, but crows prove that this is unfair. Now it has been discovered that crows may understand analogies (类推法)It was once thought that only humans could understand analogies, which help us to solve problems creatively, put things into categories， and make scientific discoveries.To test this ability in animals, scientists do “relational matchingtosample”(RMTS) tests, according to the IFL Science website. If a pair was AA, for example, then picking BB to match it would be correct. If the pair was CD, however, then EF would be correct.Apes and monkeys have learned RMTS, but scientists wanted to know if crows could do it, too. An international team led by Edward Wasserman from the University of Iowa in the US first trained two hooded crows to match things by color, shape, and number in what is called “identity matchingtosample (IMTS)”， then moved onto RMTS.For the IMTS test, the birds were put in a cage with a plastic tray that had three cards and two cups in it. The card in the middle was the sample card. The cups on either side were covered with the other two cards: One was the same as the sample (in the color, shape, or number of shapes pictured), while the other wasnt. The cup with the card that matched the sample card contained two worms to eat.In the second part of the experiment, the birds were tested with relational matching pairs. A card with two samesized circles, for example, meant they should pick the test card with two samesized squares and not two differentsized circles. The birds did well in the more difficult test and picked the correct card more than three quarters of the time, Science News reports.Wasserman was surprised that crows were able to solve the problem without any training in RMTS. “What the crows have done is extraordinary，” he said in a news release. “Honestly, if it was only by force that the crows showed this learning, then it would have been an impressive result. But this was spontaneous.”So perhaps its time to stop saying “birdbrain” in the opening paragraph?篇章导读：通过对乌鸦的研究表明，乌鸦表现出了以前人们没有意识到的鸟类的智力。6Why does the author mention the expression “birdbrain” in the opening paragraph?ATo get the reader interested in the origins of the expression.BTo urge people to stop saying that birds are stupid.CTo introduce the topic of Edward Wasserman and his experiments.DTo introduce recent findings about crows intelligence.答案：D推理判断题。根据第一段中的“.but crows prove that this is unfair. Now it has been discovered that crows may understand analogies (类推法)”可知，此举是为了引出关于乌鸦的智力的最新发现。故D选项正确。7Which of the following is TRUE about the tests on the hooded crows?AThe birds did better in RMTS than in IMTS.BThe birds were first made to do RMTS, then IMTS.CThe birds picked almost all the correct cards in RMTS.DIn the IMTS test, the birds needed to identify the sample card to get rewards.答案：D细节理解题。根据第五段最后一句“The cup with the card that matched the sample card contained two worms to eat.”，可知在IMTS实验中，鸟儿需要识别样卡才能得到奖励，即两条虫。故答案选D。8In the RMTS test, if the birds were given the sample card with two samesized triangles, they had to pick the test card with _.Atwo samesized circlesBone circle and one triangleCtwo differentsized circlesDtwo differentsized triangles答案：A推理判断题。根据第六段第二句“A card with two samesized circles, for example, meant they should pick the test card with two samesized squares and not two differentsized circles.”可知，在RMTS实验中，一张有2个相同大小的圆的样卡应匹配另一张有2个相同大小的正方形的卡。以此类推。故答案A正确。9The underlined word “spontaneous” in the secondtolast paragraph is closest in meaning to _.Acentral BcreativeCnatural Dpredictable答案：C词义猜测题。上文提到乌鸦的这种表现并没有经过训练，故可知spontaneous意为“自然的”。故C项正确。10Which of the following can be the best title for the passage?AMonkeys Are Clever Than CrowsBCrows Show ClevernessCCrows Did Well in RMTSDCrows May Understand Analogies答案：B主旨大意题。通读全文可知，通过对乌鸦的研究表明，乌鸦表现出了让人意想不到的聪明。故B项正确。1category n. 类别；种类 2.tray n. 盘；托盘3contain vt. 包含；含有4relational adj. 有关的；相关的5release n. 公开；发布1on either side 在任何一边；在两边都2the same as 与一样.短文改错(建议用时8)My mother is a teacher work in a key high school. She is too busy that she often has to get up early and stay up late. In addition to this, she hardly has any times to take exercise. She has been on poor health for some time. My father and I are worried that she may fall ill if she works too hard. These days Im thinking why to develop my mothers interest in playing sports. Considered that today is Mothers Day, I decided buy a pair of jogging shoes for her. I secret put them on the desk in her study. When my mother entered into her study this evening, she looked surprised, but she immediately realized my intention. She promises that she would go jogging every evening.答案：第一处：workworking考查现在分词作后置定语。因work与a teacher之间为主动关系，且是主动含义，因此用现在分词作后置定语。第二处：tooso考查固定结构。本句式为so.that结构。第三处：timestime考查固定搭配。have time to do sth中的time为不可数名词。第四处：onin考查介词。in poor/good health“身体差/好”。第五处：whyhow考查副词。根据句意应为how，此处表示如何培养母亲在运动上的兴趣。第六处：consideredconsidering考查现在分词作状语。动词consider与主语I之间为主动关系，因此用现在分词。第七处：buy前加to考查动词不定式。decide to do sth“决定做某事”。第八处：secretsecretly考查副词。副词secretly修饰动词put。第九处：去掉enter后的into考查动词用法。enter是及物动词，其后应直接跟宾语(her study)；再者enter的含义就是“进入”，也说明无需into。第十处：promisespromised考查动词的时态。根据上下文可知，应用一般过去时。
