Unit 3 Inventors and inventions一、阅读理解。Bees play a vital role in the world.Unfortunately，bees are dying by the second.The main purpose of bees is to make honey.Honey, shockingly，does not exist for human consumption；it is essential to the insects.Honeybees store honey in their hives (蜂箱)in order for the bees to have energy for their flight muscles and for heating the hives during the winter period.They collect pollen(花粉)which supplies protein for young bees to grow.According to National Honey Board，the increased production and quality of agricultural crops as a result of honeybee pollination are valued at more than $14.6 billion per year.These insects are responsible for over 70 of the fruits and vegetables we eat today，including apples，grapes，coffee, beans，and broccoli.So if they are so valuable to agriculture，why do they keep dying off？A key suspect seems to be pesticides(农药)Honeybees who are exposed to pesticides result in the damage to their neurological(神经系统的)functions, specifically memory or behavior.And thats why the majority of worker bees disappear and leave behind a queen，plenty of food and a few nurse bees to care for the remaining immature bees and the queen.There are several other causes of the decline of bees，including the destruction of natural habitats，like woodlands，forests，and other habitats for bees.Climate change is also a factor in the decline of the wild bee population.Actually，there are a variety of methods to help the bee population grow.One way is to start your own organic garden by planting beefriendly plants.Pesticides are used in both industrial practices and even in your home，so it is best to find organic seeds and weed killers.1Why do honeybees store honey in their hives?ATo provide enough honey for humans to consume.BTo draw protein out of honey for young bees.CTo help attract other insects and make hives stronger.DTo strengthen bee muscles and heat hives in winter.2Apples and beans are mentioned in the third paragraph to show that _.Abees supply human beings with basic foodBbees mainly live on these agricultural cropsCbees are of great importance to fruits and vegetablesDbees can bring in more money for farmers every year3What is most likely to cause the worker bees to leave their hives behind?AThe lack of food.BThe abuse of pesticides.CThe fighting among bees.DThe destruction of the habitats.4What would the author probably discuss in the paragraph that follows?AAnother way to save bees.BOther tips for choosing seeds.CMore methods to plant green organic fruits.DCauses of the decline in the wild bee population.【解题导语】本文是一篇说明文。蜜蜂在生物世界里起着重要的作用，但是由于农药的滥用，蜜蜂正在大批死亡。本文给出了增加蜜蜂数量的方法和建议。【难句分析】These insects are responsible for over 70 of the fruits and vegetables we eat today，including apples，grapes，coffee，beans, and broccoli.分析：本句为主从复合句，句中we eat today为省略了that的定语从句，修饰先行词the fruits and vegetables。译文：这些昆虫对我们如今所食用的超过70种的水果和蔬菜负责，包括苹果、葡萄、咖啡、豆类和西兰花。1D考查细节理解。根据第二段的第三句“Honeybees store honey in their hives(蜂箱)in order for the bees to have energy for their flight muscles and for heating the hives during the winter period”可知，蜜蜂储藏蜂蜜是为了增强飞行肌肉的力量，在冬天为蜂箱加热，故D项正确。2C考查细节理解。根据第三段的“These insects are responsible for over 70 of the fruits and vegetables we eat today，including apples，grapes，coffee，beans，and broccoli”可知，该段提及苹果和豆类旨在说明蜜蜂对水果和蔬菜的重要作用，故C项正确。3B考查细节理解。根据第四段的“Honeybees who are exposed to pesticides.And thats why the majority of worker bees disappear”可知，农药的滥用导致了工蜂离开蜂箱，故B项正确。4A考查推理判断。根据第五段的第一、二句“Actually，there are a variety of methods to help the bee population grow.One way is to start your own organic garden by planting beefriendly plants”可知，该段主要介绍了帮助蜜蜂增加数量的方法之一：种植对蜜蜂无害的植物。据此可以推断，下文将介绍其他的帮助增加蜜蜂数量的方法，故A项正确。二、单句语法填空1Some people say that classical music _(associate) only with old people.答案：is associatedbe associated with . “与有关”。2Though we are living a better life, I cant bear _(see) food thrown away.答案：seeingcant bear doing . “不能忍受做某事”。3What was it that distinguished her _her classmates?答案：fromdistinguish . from . “把与区分/辨别开”。4We must always bear in mind _China is a big country with a huge population.答案：thatbear in mind that . “记住”。5The service offers young people _(practice) advice on finding a job.答案：practical此处应用形容词修饰其后的名词advice。practical “实用的；实际的；实践的”。6We all have an _(expect) that he can pass the driving test next week.答案：expectation由空前的冠词可知应填名词。7In my opinion, only by facing difficulties bravely and _ (seize) opportunities can one succeed.答案：seizing该句为“only状语”位于句首引起倒装的句式。face与seize为and连接的两个并列成分，且均作by的宾语，故由facing可知应填seizing。8It was not until she got home _ Jennifer realized she had lost her keys.答案：that该句为含有not until的强调句。由该句型“It is/wasnot until .that其他”可知，应填that。9She _(tap) me on the shoulder but I didnt feel it.答案：tapped由but连接并列成分可知，设空处动词在句中作谓语；且后面并列句的谓语为didnt .，所以空格处也应用一般过去时，应填tapped。10Prices of daily goods _ (buy) through a puter can be lower than store prices.答案：bought过去分词短语在句中作后置定语修饰goods。三、完形填空。Not many people can say theyve been hit by a vehicle, but I can.
