1The article entitled Eating Iron in last months issue of Eating for Health reported that a recent study found a correlation between high levels of iron in the diet and an increased risk of heart disease. Further, it is well established that there is a link between large amounts of red meat in the diet and heart disease, and red meat is high in iron. On the basis of the study and the well-established link between red meat and heart disease, we can conclude that the correlation between high iron levels and heart disease, then, is most probably a function of the correlation between red meat and heart disease.

　　Your recent article on corporate downsizing in the United States is misleading. The article gives the mistaken impression that many competent workers who lost jobs as a result of downsizing face serious economic hardship, often for years, before finding other suitable employment. But this impression is contradicted by a recent report on the United States economy, which found that since 1992 far more jobs have been created than have been eliminated. The report also demonstrates that many of those who lost their jobs have found new employment. Two-thirds of the newly created jobs have been in industries that tend to pay above-average wages, and the vast majority of these jobs are full-time.

　　Downsizing is the process in which corporations deliberately reduce the number of their employees.

　　3According to a poll of 200 charitable organizations, donations of money to nonprofit groups increased by nearly 25 percent last year, though not all charities gained equally. Religious groups gained the most , followed by environmental groups , whereas educational institutions experienced only a very small increase in donations . This poll indicates that more people are willing and able to give money to charities but that funding for education is not a priority for most people. These differences in donation rates must result from the perception that educational institutions are less in need of donations than are other kinds of institutions.

　　4A new study collected data that shows that people who snore are more likely to gain weight than are people who do not snore. It is well known that many people who snore also stop breathing frequently during the night for a few seconds, a condition called sleep apnea. The interruption of breathing wakes the person ― often so briefly that the waking goes unnoticed ― and can leave the person too tired during the day to exercise. Anyone who snores, therefore, should try to eat less than the average person and to exercise more.

　　The librarians in our towns school system have reported that the number of trips that our students make to their school library on a voluntary basis has decreased significantly in recent years. For example, the average seventh-grade student visited the school library five times last year, but four of those visits were part of required classroom activities. This shows that our students are reading less than in the past. To address this problem, our town needs to improve the atmosphere of the libraries so that they will be comfortable places in which to work. If students view the libraries as uncomfortable, then they are unlikely to want to spend much time there.

　　1上一期的《健康飲食》雜志上刊登的題為《食鐵》的文章報(bào)導(dǎo)說最近一項(xiàng)研究發(fā)現(xiàn)飲食中鐵的含量過高與心臟病發(fā)病率增加有關(guān)聯(lián)。而且，我們已經(jīng)知道飲食中大量的牛羊肉和心臟病是有聯(lián)系的，牛羊肉中鐵的含量很高。基于以上研究和牛羊肉與心臟病之間的已知聯(lián)系，我們可以得出結(jié)論，高鐵含量與心臟病之間的關(guān)聯(lián)最有可能是牛羊肉與心臟病之間關(guān)聯(lián)的作用。

　　2你們最近關(guān)于美國集體裁員的文章是有誤導(dǎo)性的。該文章給人們一種錯(cuò)誤的印象，即很多在企業(yè)面臨嚴(yán)重經(jīng)濟(jì)困難的時(shí)候裁員而導(dǎo)致失業(yè)的有能力的工人通常要用幾年的時(shí)間找到另一份合適的工作。但這種感覺與最近一次關(guān)于美國經(jīng)濟(jì)的報(bào)告相矛盾，報(bào)告發(fā)現(xiàn)自1992年以來新增的就業(yè)機(jī)會(huì)數(shù)量遠(yuǎn)超過消失的崗位數(shù)量。該報(bào)告也指出很多失業(yè)人員已經(jīng)找到了新工作。新增就業(yè)機(jī)會(huì)中有三分之二是那些提供高于平均水平薪酬的企業(yè)提供的，而且這些崗位絕大多數(shù)是全職工作。

　　3根據(jù)一項(xiàng)針對200個(gè)慈善組織的調(diào)查，去年對于非營利團(tuán)體的捐款上升了將近25%，而并不是所有組織都獲得了同樣的增幅。宗教團(tuán)體增幅最大(30%)，其次為環(huán)境組織(23%)，而教育機(jī)構(gòu)所獲捐款僅有少量增長(3%)。這一調(diào)查說明有的人愿意而且有能力為慈善組織捐款，但資助教育并不是大多數(shù)人的首選。這種捐款比率上的差異一定是由于人們認(rèn)為教育機(jī)構(gòu)沒有其他組織更需要資助的觀念而導(dǎo)致的。

　　4一項(xiàng)新的調(diào)查所收集的數(shù)據(jù)顯示打呼嚕的人比不打呼嚕的人更容易長胖。我們知道很多打呼嚕的人夜間也經(jīng)常有數(shù)秒鐘的呼吸停頓，這種現(xiàn)象被稱為睡眠呼吸中斷。這種呼吸的停頓導(dǎo)致本人醒來通常十分短暫以至于不被察覺并且會(huì)使本人在白天很累而無力鍛煉。因此，所有打呼嚕的人都應(yīng)該比正常人少吃多鍛煉。

　　5我市學(xué)校系統(tǒng)的圖書館管理員報(bào)告說近年來我們的學(xué)生主動(dòng)去學(xué)校圖書館的次數(shù)顯著下降。舉例來說，去年7年級學(xué)生平均去圖書館5次，但其中有4次是教學(xué)活動(dòng)所要求的。這表明我們的學(xué)生讀書比以前少了。為解決這一問題，我市需要改善圖書館的環(huán)境使他們適于工作。如果學(xué)生認(rèn)為圖書館不舒服，他們將不太可能想在這里花很多時(shí)間。
