小白老师说:法国杰出的外交家塔列兰曾经说过:“熬制得最理想的咖啡,应当黑得像魔鬼,烫得像地狱,纯洁得像天使,甜蜜得像爱情。”
嗯,说得太好了
为什么咖啡于我,却完全没这么浪漫
因为每天晚上带宝宝睡觉
睡眠质量非常差
有娃且自己带娃的宝爸宝妈们应该有体会
小孩子睡觉是整床转着睡
妈咪晚上睡不好白天精神差
不喝咖啡分分钟崩溃
昨天下午咖啡喝得有点多
结果到了半夜一点钟还丝毫没有睡意
睡不着照例是要起来翻冰箱的
结果发现一周前做的荔枝酒
因上次做了杨梅酒
闺蜜撒娇说要喝荔枝酒
就特特地浸了一瓶
此时倒来喝了催眠刚刚好
今天期末大考在学校监考一天累成狗
到下午又是黑咖一大杯
话说一考完同学们纷纷表示心情糟透
吐槽英语期末试卷太凶残
更有孩纸或是微信或是QQ向小白老师各种表白
说老师老师我爱你
这学期让我过下学期一定好好学
言辞恳切得让人心疼
小白老师怎么会忍心拒绝呢
小白老师怎么会是那种不讲情面的老师呢
嘿,还真的是
同学们考得不理想
势必要影响小白老师批改试卷的流畅度
明天阅卷一天
看来又是一场恶战
赶紧先把咖啡准备好

下面请大家倒上一杯香醇的咖啡,来听最优美的英文。VOA慢速英语,常喝咖啡是否有益身体健康。
From VOA Learning English, this is the Health and Lifestyle report.
Today we have more good news for all our coffee drinkers around the world. Another new study finds that drinking coffee can help you live longer.
Researchers at the Harvard School of Public Health recently discovered that drinking between three and five cups of coffee a day may prevent certain illnesses.They found that coffee can protect against heart disease, brain diseases, type 2 diabetes and suicide(自杀).
Walter Willett is a nutrition researcher at Harvard and co-author of the study. Willet says the findings extend to both caffeinated(含咖啡因的) and decaffeinated(不含咖啡因的) coffee – or decaf(无咖啡因咖啡), as Americans often call it.

So, the health benefits come not just from the caffeine in coffee, but from the compounds(化合物) in the beans(豆,咖啡豆).
The large study of about 200,000 subjects included data from three ongoing studies. Subjects in the study had to answer questions about their coffee drinking habits every four years over a 30-year period.
Researchers found that moderate coffee drinking was linked with a reduced risk of death from many diseases. These diseases include cardiovascular disease(心血管疾病), diabetes(糖尿病), neurological diseases(神经系统疾病) such as Parkinson’s(帕金森症), and suicide.

However, the researchers found no link between coffee drinking and cancer.
Researchers also considered other habits such as smoking, obesity(肥胖), and how active the subjects were. They also looked at what kinds of food the subjects ate, as well as how much alcohol – and what type of alcohol – they drank.
They published their findings in the journal Circulation.
This Harvard research adds to a growing body of evidence. This body of evidence finds that drinking a moderate(中等的,适量的) of coffee may have many health benefits, including a longer life. This is according to one of the researchers involved in the study.
Frank Hu is senior author of the study. He is also a professor of nutrition(营养学) and epidemiology(流行病学). He studies how food affects illness.
Hu adds that data from the study support the 2015 Dietary Guidelines Advisory Report. This report found that drinking a moderate amount of coffee can be part of a healthy diet.
But how much and when you drink coffee is important.

You may remember another study we reported on recently. That study said that drinking coffee too late in the evening can disrupt your sleep.
Not everyone feels the recent Harvard study confirms anything.
The news organization NPR spoke with one expert who warns that not everyone reacts to coffee the same way. Andrew Maynard of Arizona State University told NPR that the health benefits documented(有案可查的) in this new study are “small.”
Maynard says the study does not prove cause and effect between drinking coffee and living longer. He says the study points to an association,or link, between drinking coffee and living longer.
Even those involved in the research still have questions.
When NPR spoke with study co-author Walter Willett, he said he is not sure how coffee is linked to certain health benefits.
Willett says the take — home message — in other words, the important thing to learn — is that if you like coffee, do not feel guilty about drinking it in moderation. If you don’t like coffee, don’t feel you have to start drinking it to be healthy.
