1. Workers who can still demonstrate their capacity to carry out their work should not be asked to retire, simply because they have reached a certain age.

2. We had only expected around 20 people to apply for that post, but twice as many showed up. So we had to work overnight for the arrangement of interviews.

3. Many American companies now understand that they must study Chinese laws, trade practices and culture in order to be more effective in doing business with their new trading parnters.

4. Not long ago, people were still arguing over whether or not climate change was actually taking place. Now there is broad consensus that it is happening, and that human activities are largely to blame.

第一句难度中等，与现实颇为贴切，不需做太多笔记即能翻译，考生应注意前后语序的调整。

第二句出现了数字，但非常简单，20和twice，稍做笔记即可。

第三句中出现了列举，新东方课堂上特地强调过列举的重要性，不管是哪种词性都必须笔记，所以考生必须记下句中的Chinese laws, trade practices and culture。

第四句的主题是大家熟悉的环境问题，句中难词broad consensus（广泛一致），即使考生一时没有听懂，也可以根据句中but的转折关系判断出。

第五句讲的是人类的智商。一开始考生听到attributable可能会卡壳，但课上我特别提醒过，碰到不懂的字就放弃而不要过多纠缠。因此当听到之后的heredity和environment，就应该能正常联想到是影响智商的因素。
