6、nions. About a third of the food we eat is a result of pollination of the bees. Unfortunately, bees have been disappearing at an alarming rate.In 2006, bee keepers started reporting about something called Colony Collapse Disaster (CCD).The main sign of CCD is the loss of adult honey bees from a hive
7、. In October of 2006, some beekeepers reported that they had lost between 30 and 90 percent of their hives.There were many theories for the disappearance of the bees. But the most convincing one has to do with pesticides and lifestyles of bees today. Nowadays, beekeeper get most of their income not
8、from producing honey but from renting bees to pollinate plants. This means that the life of the typical bee now consists of travelling all around the country to pollinate crops as the seasons change. That means a lot of traveling on trucks, which is very stressful to bees. It is not unusual for up t
9、o 30% of the hive to die during transport due to stress. In addition, bees that spend most of their time locked up on trucks are not exposed to what they usually live on. Instead, they live on a sweet liquid from corn, usually polluted with pesticides.The exact reason for the disappearance of bees i
10、s not sure, but losing bees is very costly to the economy. The bee pollination services are worth over $8 billion a year. With no bees, pollination will have to be done by hand, which would have effects on the quality of food and increased food priced. We hear a lot about big environmental disasters
11、 almost every day. But one of the biggest may just be the less of that tiny flying insect._【答案】Bees not only provide us with honey, but also help pollinate crops.

14、ions: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible. Its a common sight to see food delivery workers riding electric bikes through big cities in China. Most of them seem to be in a hurry, a
15、s they run red lights to deliver their meals in time. However, such reckless(鲁莽的)behavior often causes serious problems. In the first half of this year, food delivery drivers had 76 traffic accidents in Shanghai alone, according to the Shanghai Public Security Bureau. This means that on average, the
16、re is a food delivery worker that gets hurt or even dies on the road in Shanghai every 2.5 days.Other cities also share similar problems. In Nanjing, three people died and 2,473 were injured in road accidents related to food delivery workers in the same period, according to the Ministry of Public Se
17、curity.The rise of reckless behavior among food delivery workers is closely related to the growing demand for their service, reported Peoples Daily. About 150 million people in China use food delivery services, according to China Radio International (CRI). Such a big market has led to a large demand
18、 for food delivery workers, with some companies offering high salaries to attract new workers.However, food delivery workers are often under high pressure from their employers. They face company fines of 20 yuan for delivering food late and upwards of 200 yuan for receiving complaints, reported CRI.
19、 Moreover, the more orders they take, the more commission(佣金)they can earn, leading to some workers checking their mobile phones for new orders while theyre riding their bikes.While most companies have measures requiring delivery workers to follow traffic rules, “there remains a problem of whether t
20、hese requirements and rules for delivery workers are truly entering their ears, brains and hearts,” Wang Liang, deputy head of the Traffic Police Security Bureau, told news website The Paper.To solve the problem, some cities have taken action. Shanghai has asked companies to train their workers on t
21、raffic rules and safety. Now in Shenzhen, if a delivery worker gets caught breaking traffic rules more than twice, he or she will be banned from driving food delivery vehicles for a whole year.【写作指导】1. 首先分析文章可以分为几个主要部分,分割完之后对每个部分主要内容进行总结概括即可。这篇文章大致可分为三个部分,第一部分paragraph 1-3,第二部分paragraph 4-6,最后一部分par
22、agraph 7。2. 第一部分是主要引入话题,很多城市的外卖送餐员为了尽快送快递,会闯红灯等,导致交通事故。总结出Food delivery workers have a higher risk of getting involved in traffic accidents.3. 第二部分包含三段内容,主要分析外卖送餐员莽撞行为的原因,一方面是送外卖业务需求量大;其次是他们面临罚款和投诉压力;且为了更高的收入,他们多接单。所以总结为:The large demand for their service, the high pressure from employers and their
23、strong desire to earn more commission lead to their reckless behavior.4.最后一部分阐述一些城市解决该现象的一些方案。比如对外卖送餐员进行交通安全的培训,或者对破坏法规两次以上的进行更严格的惩罚。可以总结为:In some cities, measures like stricter road safety education and more severe punishment have been taken to solve this problem.【参考范文】Food delivery workers have a
24、higher risk of getting involved in traffic accidents. The large demand for their service, the high pressure from employers and their strong desire to earn more commission lead to their reckless behavior. In some cities, measures like stricter road safety education and more severe punishment have bee
25、n taken to solve this problem. (58 words)SummaryDirections: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible.A large source of rubbish is packaging material. It often makes up more than 30 per
26、cent of the total. To understand why this is true, think of the packaging commonly used for a simple product, such as toothpaste. The packaging includes not only the tube for the toothpaste, but also the box for the tube. This box is put into a plastic wrapper. Then, the boxes are transported in a c
27、ardboard container.Most packaging material ends up in a landfill after it is thrown away. Though necessary, landfills take up valuable space, often stink(发出恶臭), and can leak harmful substances into the soil. Landfills not included, the production of packaging material itself is a major source of air
28、 and water pollution.People are now trying to solve the problems caused by packaging materials. In 1991, Germany took the lead by requiring companies to recycle the packaging used for their goods. To do this, the companies set up recycling bins in every neighborhood. Consumers now separate their rub
29、bish into three categoriesmetal, plastic and paper cartons. They then put it into the appropriate bin. The rubbish sorted, it is transported to a recycling company for processing.The programme worked well at first. However, the amount of rubbish has begun to increase again. One reason for this is th
30、at many consumers no longer reduce waste because they think the problem is solved. It seems that to properly deal with the problem of rubbish, everyone must remain alert and do their part.【写作指导】根据文本内容,这是一篇讲包装材料所带来的问题的说明文,要求对其进行概要写作。因此,我们必须首先弄清每一段落的主要内容是什么。第一段开头第一句话“A large source of rubbish is packa
31、ging material. It often makes up more than 30 percent of the total.”是段落的中心句,同时也点明了文章的主题,后面就在以牙膏为例进行举例说明。第二段主要讲的是包装材料所带来的问题,主要包括两方面,一是垃圾进入填埋场后所造成的污染;二是这些包装材料在生产过程中会产生对空气和水的污染。第三段主要在讲人们正在采取措施解决包装材料所带来的问题,其中第一句“People are now trying to solve the problems caused by packaging materials.”是段落的中心句,后面就在用德国的事
32、情举例说明,政府、制造商和个人采取的措施试图解决包装材料带来的污染问题。第四段开头的however至关重要,说明德国的方法尽管起到了一定的作用,但包装材料的污染仍然是一个大问题,我们绝不能放松警惕。弄清了每段的主要内容后,我们就按照概要写作的几个原则对其进行连接,在连接段落时需要添加必要的连接词使其通顺连贯即可:【参考范文】The article points out the problem of packaging. About one third of rubbish results from the packaging materials, which cause damage to t
33、he environment during their production and after ending in landfills. Though the programs carried out to combat the problem are temporarily successful, the problem remains a great concern. 实战演练AAre you working with your computer routinely either as a office employee or a game lover? Are your eyes dr
34、y, watery, blurry, seeing double or sensitive to light? If your answer is a “yes”, you are likely one of many people today who suffer from digital eyestrain, also called computer-vision syndrome. What on earth is this syndrome coming from? What can we do to deal with this problem?Eyestrain is often
35、related to the amount of exposure to screens, the distance from eyes to screens and the use of multiple screens simultaneously. However, studies have also shown that the blue light produced by digital devices today reaches further into the eyes than other kinds of light. This light actually assists
36、attention during the day but can result in interrupted sleep patterns at night.Years of scientific researches indicate that eyestrain isnt necessarily an unavoidable problem for those who deal with computer work in the daily base. There are ways you can adopt which can overcome the problem considera
37、bly. To begin with, your computer screen should be high-resolution (高分辨率), at least 50 centimeters wide diagonally and may require a screen filter to decrease reflections. Also, be aware that “computer glasses”, which cut down glare and blue light,are available.Besides, to reduce your risk for compu
38、ter-vision syndrome, take frequent breaks during your computer workday. Many workers take only two 15-minute breaks from their computer throughout their day. According to a recent study, eyestrain are significantly reduced when computer workers take four additional five-minute “mini-breaks” througho
39、ut their workday. Finally, many of us fall into bad habits while using digital screens, which only worsen the effects of eyestrain. While viewing digital screens, many people blink (眨眼) one third less often than they usually do. Place a reminder on your computer to “blink” so that your eyes dont dry
40、 out._【答案】Digital eyestrain is related to the amount of exposure to screens and the distance of the eyes to the screens. Scientists suggest we should use high-resolution screens and try to decrease reflections. Moreover, besides longer breaks, we should take more additional mini-breaks. Finally, rem
41、ind ourselves to blink as much as possible to prevent our eyes from drying out.【解析】本文为说明文。文章对 “数码眼疲劳”也被称为“电脑视觉综合症”的症状、原因及如何避免进行了介绍。眼睛疲劳通常与接触屏幕的次数、眼睛与屏幕的距离以及同时使用多个屏幕有关。因为数字设备产生的蓝光导致眼睛干涩、模糊的、对光敏感等。研究发现眼疲劳是可避免的,首先要减少屏幕的反射,此外要经常休息或增加间隔休息时间,最后要提醒自己尽量多眨眼睛,以防眼睛干涩。【详解】本文首先要概括出四段的大意。第一段介绍了什么是“Digital eyestra
42、in”,也叫做“computer-vision syndrome”及其症状。第二段叙述眼睛疲劳的原因,即眼睛疲劳有关的内容,即与“Eyestrain is often related to the amount of exposure to screens, the distance from eyes to screens and the use of multiple screens simultaneously”这是确切的定义,可照搬。第三段和第四段主要叙述了如何避免眼疲劳,即尽量避免反射(try to decrease reflection.),多休息(longer breaks)以及
43、提醒自己多眨眼(remind to blink),以防眼睛干涩(此句要用动词不定式来表示目的)。最后按照大意,用恰当的句式表达出来即可。在用英语句式表达时,要尽可能用自己的话,让句子灵活多变些。但句式一定要符合英语语言的要求,避免运用汉语式的英语。答案如下:Digital eyestrain is related to the amount of exposure to screens and the distance of the eyes to the screens. Scientists suggest we should use high-resolution screens and
44、 try to decrease reflections. Moreover, besides longer breaks, we should take more additional mini-breaks. Finally, remind ourselves to blink as much as possible to prevent our eyes from drying out. BImagine living on the edge of a vast desert, which is moving quietly closer to your village every da
45、y and covering your fields. The desert is on the move. This is called desertification.Desertification occurs in regions close to an already existing desert. It generally arises from two related causes. The first is over-use of water in the area. There is not enough water in any case, and if it is no
46、t carefully used, disaster can follow. As time goes on, water shortages make farming more and more difficult. In some places, locals can remember local lakes and marshes which were once the homes for all kinds of fish and birds. They have been completely buried by the sand now. Farmers leave the lan
47、d, and fields are replaced by deserts.The second cause is misuse or over-use of the land. This means that the wrong crops are planted and need more water than is available. Ploughing large fields and removing bushes and trees means that the wind will blow away the soil. Once the soil is lost, it is
48、hard to replace, and if there is rain, it has nowhere to go, and brings no benefit.It is not only the farmers and villagers who suffer. Every spring, the skies over some of eastern cities, thousands of kilometers away from the deserts, can be darkened by sandstorms. Dust from deserts can have a grea
49、t effect on weather systems. While desertification is perhaps being partly caused by global warming, these sandstorms can make global warming worse by adding to what is known as the greenhouse effect.What can be done to slow down or stop the process of desertification? A great deal of work is alread
