咖啡的生长过程
咖啡原产于非洲的埃塞俄比举运亚,她是茜草科咖啡亚属和段的常青树,一般所说的咖啡豆其实是咖啡树所结正棚梁的果实,由于形状像豆子,所以叫咖啡豆。气候是咖啡种植的决定性的因素,她适合生长在热带和亚热带的南北纬25度之间的地带,一般称为"咖啡带"。阳光的照射,温度,湿度,降雨量,土壤的肥沃程度,土壤的排水性也都是非常重要的因素,都会对咖啡的品质产生影响。咖啡第一次开花约在树龄3年左右,花朵为白色的五瓣筒型,散发出淡淡的茉莉花香。花絮浓密呈串状排列。花朵凋谢后约两三个月结出成串的果实,最初为绿色,成熟后为红色,这就是我们常说的"咖啡樱桃"。
急求英语口语小短文:talking about life in the city and suburts 两三分钟之内的。
Life in the city is convenient, exciting but fastpaced and busy. Life in the suburbs is relatively slow, relaxing but it can get dull too. While living in the city, you’d probably be closer to your workplace, and that leaves less time on the road where you can listen to music, call a friend or whatever makes you feel nice, which if you live in the suburbs, you’d have plenty of time to do on the road. Also if you live in the city, you’d be likely to participate in social activities as you live closer to where most of them happen, and in the suburbs, you’d probably be unwilling to go as it would take more time, so it could get boring. On the other side you have much more alone time, you’d be more likely to have a garden because of the low housing price, and you can do gardening, or even fishing if you live near some river that’s unlikely to appear in the middle of town.
So living in either place can be fun, the choice depends on what kind of person you are.
