Tip:Put 50g jasmine tea into silk stockings, tie it up and put into refrigerator--a good way to remove compound smell of food. You can take it out once a month for solarizing under the sun bacause jasmine tea can be recycled.

将约50克的茉莉花茶叶放进丝袜内，绑扎后放在冰箱内，可缓和冰箱内的杂食味，每隔一个月取出茉莉花茶叶放在阳光下暴晒，可循环再用。

After the removal of the recyclables and either combustion or composting of the fibre only around 4% of sanitised inert material is needed to be landfilled or used in land preparation.

除去可循环垃圾以及纤维的燃烧或堆肥后，仅有 4%的已消毒惰性材料需要进行掩埋或土壤准备。

This paper discusses the conception of a carry-home high precision temperature equipment verification device based on a MSC1210 single chip computer. The device samples temperature signal by temperature sensor, standard platinum resistance and thermocouple, and realize multi-channel temperature meterage by controlling relay switch. The result be sent and displayed on LCD.

本课题研制出一种以MSC1210单片机为核心的便携式高精度温度试验设备检定仪，它以标准铂电阻和标准热电偶为传感器，通过控制继电器实现对温度试验设备的多通道循环温度测量，测量结果转化为温度值后由LCD显示。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
