But for plants，nectar production is costly—it requires vital energy and nutrients，so some plants try to cheat honeybees out of their food rewards by using the same attractive smells falsely to advertise poor quality nectar，or even none at all. Is it possible that honeybees are fooled by these cheats？No.Bees quickly distinguish which flowers produce the best nectar by their smells，even when the smells are extremely similar，a recent study by the scientists at Newcastle University in the UK has shown. Led by biologist Geraldine Wright，the scientists exposed collected worker honeybees to two different odors(氣味)based on natural floral compounds(化合物)．One odor led to a food reward having more sugar and the other food reward contained more salt.They found that the bees were able to tell apart the two odors based on their associated rewards.Wright explained that honeybees like sugary nectar and dislike salty nectar.How delicious or awfultasting the food nectar is to them determines how strong the bees preference is to the scent(香味)signals. Their research shows that bees can learn about the signals related to nectar quality，and they have ways to avoid floral “cheaters”．They prefer to visit the floral scents theyve learned to associate with profitable rewards，Wright told at www.discoverynews.com. To honeybees，the smell signal is even more crucial than the look of a flower. Wright explained：“When the floral scent isnt correct，even if the visual_aspect of the flower is exactly the same，a bee will not visit it.” The study suggests that a bees ability to learn which smells produce the best nectar may be the key to understanding how the smell of flowers has evolved in flowering plants. “It forces flowering plants to be honest about the rewards they advertise and honeybees may even select plants with both scented flowers and high quality flowers，”she said，“because these plants outcompete others in the floral market place.” 【解題導(dǎo)語】 本文是一篇科普說明文，介紹了蜜蜂具有識別花蜜質(zhì)量的能力。 16．This passage is mainly about________. A．how floral scents are evolved to attract honeybees B．the reasons and the ways flowers attract honeybees C．honeybees ability to distinguish high quality flowers D．how honeybees learn not to be fooled by plant cheats 答案　C　[主旨?xì)w納題。第三段是整篇文章的主題段落，主要介紹了蜜蜂具有識別花蜜質(zhì)量 的能力，有了這種能力蜜蜂才不會被一些假花蜜所欺騙，下文通過介紹科學(xué)家的研究來證明 此觀點。] 17．What is the food a honeybee gets? A．Nectar. B．Honey. C．Scents. D．Nutrients. 答案　A　[細(xì)節(jié)理解題。根據(jù)第一段的內(nèi)容可知，蜜蜂從鮮花中采取花蜜，因此也給它們授 了粉，故A項是最佳答案。] 18．Which of the following is TRUE according to the passage? A．The look of a flower matters as much as its scents to a honeybee. B．The honeybee will visit a plant if its flower smells good. C．The honeybee will avoid a plant whose nectar is salty. D．Plants dont need to make much effort to make nectar. 答案　C　[細(xì)節(jié)理解題。根據(jù)第四段中所講述的實驗可知，蜜蜂不喜歡咸味，所以它們是不 會光顧帶有咸味花蜜的植物的。故選C。根據(jù)第六、第七段可知，花的外貌不如它的香味重 要；根據(jù)第二、第三段可知，有時花雖然聞起來很好，但它是假的，這時蜜蜂會識破真相； 根據(jù)第二段可知植物造成花蜜需要維持生命所必需的能量和豐富的營養(yǎng)。由此可排除其余三 項。] 19．From the passage，we can conclude that ________. A．the visit of honeybees is not crucial for a flowering plant B．the honeybees “sweet tooth”is likely to affect the floral signals C．honeybees can judge the quality of nectar by its smells D．some plants succeed in avoiding“payment”to honeybees for their “service” 答案　C　[推理判斷題。根據(jù)倒數(shù)第三段“The study suggests that a bees ability to learn which smells produce the best nectar may be the key to understanding how the smell of flowers has evolved in flowering plants.”可以推斷出，蜜蜂是通過氣味來判斷花蜜的質(zhì)量的。] 20．The underlined phrase“visual aspect”most probably means “________”． A．look B．listening C．smell D．scent 答案　A　[詞義猜測題。根據(jù)上一段“To honeybees，the smell signal is even more crucial than the look of a flower.”可以推斷出答案。] Ⅲ.閱讀表達(dá)(共5小題；每小題3分，滿分15分) 閱讀下面短文，并根據(jù)短文后的要求答題。(請注意問題后的字?jǐn)?shù)要求) Psychology(心理學(xué))tells us that many people hate to take risks._But_it_is_good_for_us_to_ take_risks,_especially_when_the_risk_is_to_achieve_a_desired_result.In that way, we become stronger and braver. Our human nature should be to take risks, but some people just sit and wish they didnt have the fear to move on. This is because of one or two failures in their lives. Please step out and dont let the past hold you back from living life to the fullest. Move forward and move on! In studying the psychology of taking risks, we find that human nature provides us with the desire to experiment and take chances. Risk taking is a great benefit that allowed our ancestors(祖先) to become stronger and stronger day by day. By taking risks they fought off enemies and discovered new land.This attitude has become a part of our modern culture. Riding a roller coaster is a common risk taking activity that even the average person seems to enjoy although they have the understanding that it is dangerous. Getting in a car each day is a risk. Getting out of bed is a risk. We need to take risks so that we can finish many things. Astronauts take risks when they get inside a rocket; however, the things t hey achieve are great. Businessmen take a risk when they buy parts of a company. However, without doing that, they could not make more money. We need to take risks so that we can gain something. It is impossible to move forward in life, earn money, enjoy a relationship, play a sport, or do anything else____________.It is all part of the game. Its one of the most important parts of life. 21.
