In fact, your family will have toabsorb the losses incurred when you miss work due to smoking-related illnesses.Second, there is a lot of debate over the best way to measure the economic costsof smoking.Every study is based on different assumptions, and uses different data andmethods. For example, should you measure the cost of smoking by looking at thecost of treating major illnesses like lung cancer and heart disease, or shouldyou also measure the cost of less serious illnesses Should you take intoaccount the fact that people who live longer also pay more taxes and insurancepremiums Should you look at the overall cost to the healthcare system, or atthe cost per individualAnyway, regardless of how you calculate them, the economic costs of smokingare incons equential when compared to smoking’s real price: the misery caused bythe deaths of over 400,000 people each year and the illnesses of severalmillion.【参考译文】人们总是为开始抽烟找各种理由，但是没有一种是好的，没有所谓的利他理由。

Another kind of business is the partnership. Two or more people go into business together. An agreement is usually needed to decide how much of the partnership each person controls.
And that's the VOA Special English Economics Report, written by Mario Ritter. You can lon our website, . I'm Jim Tedder.
A corporation is recognized as an entity -- its own legal being, separate from its owners.
A board of directors controls corporate policies. The directors appoint top company officers. The directors might or might not hold shares in the corporation.
One kind of partnership is called a limited liability partnership. These have full partners and limited partners. Limited partners may not share as much in the profits, but they also have less responsibility for the business.

五年级英语基本功训练第二单元听力材料
五年级英语基本功训练第二单元听力材料 I'm sorry, but as an AI text-based model, I am unable to generate audio files or provide listening materials directly. Additionally, creating a detailed listening material with over 1000 words specific to the second unit of a fifth-grade English workbook would require access to the actual workbook and its contents, which I do not have. However, I can provide you with general guidance on how to approach creating or using listening materials for English language learning at the fifth-grade level. When preparing listening exercises, it's important to ensurethat the content is age-appropriate, engaging, and aligned with the curriculum objectives.Here are some suggestions for creating or selecting listening materials for fifth-grade English learners:1. $$Choose Relatable Content$$: Select topics that are relevant and interesting to fifth-grade students. This could include stories about school life, family, friends, hobbies, or adventures.2. **Use Clear Language**: Ensure that the language used in the listening material is simple, clear, and easy to understand. Avoid complex vocabulary or grammar structures that might be unfamiliar to students at this level.3. **Include Varied Activities**: Design listening activities that engage students' attention and challenge their comprehension skills. This could include fill-in-the-blank exercises, multiple-choice questions, or true/false statements.4. **Utilize Authentic Materials**: If possible, incorporate authentic listening materials such as excerpts from children's stories, songs, or short videos. These can provide students with real-world examples of English language use.5. **Encourage Active Listening**: Encourage students to actively listen and engage with the material. They can take notes, predict outcomes, or discuss what they hear with classmates.Remember to adjust the difficulty level of the listening material based on the language proficiency ofyour students. If you have access to the actual workbook, you can refer to its content and align the listening material with the topics and skills covered in each unit. If you need specific help with a particular aspect of creating or using listening materials, feel free to ask more detailed questions, and I'll do my best to assist you.。

【听力文摘】蛋是如何成色的
How Eggs Get Their Color
Egg Dye
De pending on the species, bird eggs can be any color ranging from chicken’s plain white to a robin’s blue, streaked, spotted, bright, pale, and anything in between.
As the egg moves down the female’s oviduct, the tube that connects the ovary to the outside, it squeezes against glands that produce colored pigments that combine to form every color in the egg shell spectrum. If the egg is stationary at the time that it comes in contact with these glands, it’ll be spotted. If the egg is in motion, it will be stre aked.
With Flying Colors
So why go through all the trouble of producing colored eggs? For many species of birds that nest out in the open, the eggs’ colors help to conceal them by enabling them to blend into the background. Another way that colored eggs come in handy, is that in some species, like murres, individual birds learn to recognize their own particular markings and reject eggs that don’t match. In contrast, birds that nest in cavities, or that start incubating as soon as the egg is laid and consequ ently don’t need to hide their eggs, tend to lay unmarked white ones.
Given all this, how do scientists explain the fact that robin’s eggs are an eye-catching, unmarked blue? Perhaps this enables robins to spot when a parasitic bird tries to add its own eggs to the nest. For some species, this may pose a greater threat than that of nest robbers.
ＰＳ：为什么鸟蛋会有各种各样的颜色？有研究认为是因为蛋壳中胆绿素-IX、胆绿素的锌螯合物、原卟啉-IX这三种色素的比例不同导致。
其中，原卟啉-IX色素形成黄色、粉红色、浅红色、淡黄或褐色，而胆绿素-IX以及胆绿素的锌螯合物形成蓝色和绿色，这三种色素按照不同比例，就形成从紫蓝色到橄榄绿等不同颜色。
除此之外，鸟蛋的颜色还与其栖息的地方有关系，栖居在洞穴中的鸟，产的蛋大多为白色，其他鸟产的蛋，有着与环境颜色近似的保护色，比如水草丛中筑巢的鸭类的蛋为浅绿色。
——《果壳网》
译文：
蛋是如何成色的
根据种类的不同，鸟类的蛋颜色各异，从白色的鸡蛋，到蓝色的知更鸟蛋，还有条纹的、斑点的、鲜亮的、浅色的，以及其它介于这些颜色的蛋。
当蛋顺着雌性鸟类的输卵管向外移动时，连接卵巢和外界的管道会挤压腺体产生色素，这些共同作用下，蛋壳就染上了各种各样的颜色。
如果蛋在接触颜色腺体时是静止的，它就会染上斑点。
如果蛋是运动的，则会染上条纹。
大获全胜
为何要如此大费周章的给蛋上色呢？对许多露天筑巢的鸟类来说，蛋的颜色有隐身的作用，可以借着颜色与外界溶为一体。
有颜色的蛋还有另一个作用，那就是对诸如海鸥之类的鸟，它们能够识别蛋上的独特印记，以丢弃那些不属于自己的蛋。
相反的，在洞里筑巢的鸟，或是一生下蛋就开始孵化的鸟，它们不需要把蛋藏起来，因此更容易生下没有颜色的白色的蛋。
既然这样，科学家又怎么解释有着显眼纯蓝色的知更鸟蛋呢？或许是因为当寄生鸟把蛋下在
知更鸟的巢里时，这会帮助知更鸟区分出它们。
对于一些鸟类来说，鸠占鹊巢比被抢了老窝更危险。
