机经编号#03 Grass and Cow
The co-evolutionary relationship between cows and grass is one of nature’s underappreciated wonders; it also happens to be the key to understanding just about everything about modern meat.
For the grasses, which have evolved to withstand the grazing of ruminants, the cow maintains and expands their habitat by preventing trees and shrubs from gaining a foothold and hogging the sunlight; the animal also spreads grass seed, plants it with his hooves, and then fertilizes it with his manure. In exchange for these services the grasses offer ruminants a plentiful and exclusive supply of lunch.
For cows have evolved the special ability to convert grass which single stomached creatures. They can do this because they possess what is surely the most highly evolved digestive organ in nature: the rumen. About the size of a medicine ball, the organ is essentially a forty-five gallon fermentation tank in which a resident population of bacteria dines on grass.

Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home. These jobs are a normal part of family life. Paying children to do extra work around the house, however, can be useful. It can even provide an understanding of how a business works.
Allowances give children a chance to experience the things they can do with money. They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want. Or they can save and maybe even invest it.
Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer services to help children and teenagers learn about personal finance.
A savings account is an excellent way to learn about the power of compound interest. Interest rates on savings can be very low these days. But compounding works by paying interest on interest. So, for example, one dollar invested at two percent interest will earn two cents in the first year. The second year, the money will earn two percent of one dollar and two cents, and so on. That may not seem like a lot. But over time it adds up.
Paying children to do extra work around the house give children a chance to experience the things they can do with money and to understand that costly goals require sacrifice, and requiring children to save part of their allowance can also open the door to future saving and investing with a saving account, which is an excellent way to learn about the power of compound interest.
机经编号#24 Skipping Breakfast
Skipping Breakfast Has Drawbacks – It’s no mystery why so many people routinely skip breakfast: bad timing. It comes at a time when folks can be more occupied with matters of grooming, attire and otherwise making themselves presentable for a new day. However, studies conducted both in the United States and internationally have shown that skipping breakfast can affect learning, memory and physical well-being. Students who skip breakfast are not as efficient at selecting critical information for problem-solving as their peers who have had breakfast. For schoolchildren, skipping breakfast diminishes the ability to recall and use newly acquired information, verbal fluency, and control of attention. According to Ernesto Pollitt, a UC Davis professor of pediatrics whose research focuses on the influence of breakfast on mental and physical performance. Skipping breakfast can impair thinking in adults, also. For both children and adults, a simple bowl of cereal with milk goes a long way toward providing a sufficiently nutritious start to the day. Green-Burgeson recommends choosing a cereal that’s low in sugar — less than five grams per serving — and using nonfat or one percent milk.

In modern society, unemployment among young people is serious problem. Some people think shorten the working (week/time) can address the problem. Do you agree or disagree?
论点1: The development of temporary forms of work such as internships, seasonal jobs and short-term contracts can leave young workers in precarious situations in terms of employability.
展开1: Because their jobs are temporary contracts, youth are often the first to be laid off when a company downsizes, and many find themselves unemployed and disadvantaged in searching for another job.
论点2: Flexible contracts with shorter working period can ensure that young people who lack work experience can prove their abilities and skills to progressively transition to regular employment.
展开2: It is seemingly impossible for young labors, who normally lack vocational skills, to secure a decent long-term occupation nowadays, which means such short-term contracts can be acted as a steppingstone for those inexperienced young adults and pave the way for long-term employment.
