Fill the blender with 1/3 of water, blend the fruits and raisins into riced size about 40sec.

先把冷开水及水果、葡萄干倒入果汁机后，打成将米粒状（约40秒）。

Yes, you ought, perhaps, to ha' done that,' snored Sir John.

&不错，你也许应该先打听打听的，&约翰爵士打着鼾声说。

There were solitary patches of road on the way between Soho and Clerkenwell, and Mr. Lorry, mindful of footpads, always retained Jerry for this service: though it was usually performed a good two hours earlier.

从索霍到克拉肯威尔的路上有一些荒凉的路段，罗瑞先生怕遇到翦径的，总预先约好杰瑞护送，虽然通常是在要比现在早两个钟头以前就动身。

Based on the results of the experiment, the results indicate as follows (1) the opportunity cost for key letter method learning of a fifth-grade student of an elementary school is 77 minutes of time;(2) the learning of the relations between letters and their chief representatives have a great transference effect on the learning of the relations between letters and their deputy representatives, and this result told us that the opportunity cost for key letter method learning could be reduced by learning and mastering first the relations between letters and their chief representatives.

实验结果表明：(1)小学五年级学生学习关键字母法的机会成本约为77分钟；(2)字母—正代表关系的学习结果，对于字母—副代表的学习具有较大的迁移作用。这说明，先学习并牢记字母—正代表关系，能够减少关键字母法的机会成本。

A pound of beef requires around 12,000 gallons of water to produce, compared to 60 gallons for a pound of potatoes. If you're a meat eater, for starters, try cutting out a serving of meat each week. Going vegetarian or vegan is a profoundly meaningful environmental choice

生产一磅牛肉，约需12，000加仑的水，而生产一磅的马铃薯，只需60加仑的水，若您是肉食者，请先试着每周减少一些肉品食用量，加入素食行列或成为全素者，是一项有显著意义的环保之举。

One was that one molecule of nitrous acid di-rectly reacted with DMA,and the other was that two molecules of nitrous acid reacted first to yield nitrogen trioxide,which then reacted with DMA.

计算结果表明，DMA与亚硝酸间接反应的活化能比直接反应的低约55kJ/mol，由此可推断DMA与亚硝酸生成NDMA的反应是以两分子的亚硝酸先生成ONNO2再亚硝化DMA为主要反应途径。

To cooperate with new and old parts: although standard zero, components, but in between interchangeable in assembly parts, and to make the optimal coordination between trim, still needs a lot of work, such as the gear and rack, boring if after removal of gear various performance indicators are used by detecting without the need to change, and to replace worn rack, rack and rack positioning pin hole on installation bolt holes and should be first, reoccupy hand crossed positioning drills and tapered reamer to match the drill and match hinge, and after the installation of new and old super-modulus gear mesh clearance to achieve technical standards, this work takes about one day.

。新，旧零部件重新配合过程：尽管标准零，部件间具有互换性，但在装配中，要使新旧零部件间的配合达到最佳状态，仍需大量的修整工作，如镗床的齿轮与齿条，若拆卸后齿轮的各项性能指标经检测尚能使用不需更换，而齿条磨损严重需更换，那么齿条及齿条安装面上的定位销孔和定位螺钉孔就需先划线定位，再用手电钻及锥形铰刀重新配钻和配铰，且新齿条安装完毕后与旧齿轮的啮合间隙需达到技术要求的标准，此项工作需时约一天。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
