 After taking some overnight rest at the hotel, walk the following day in the streets of Guangzhou could reveal that the people are very enterprising, engaged in one business or the other from one end to another in order for them to earn a living.

 也许可以这样理解:在“90后”眼中,住房条件不再是“生活质量好”的唯一、重要标准。生活质量可能包括吃饭、玩乐、休闲娱乐、体育活动等等综合维度,而这一切都会增加开支。在收入有限、开支此消彼长的选择中,高价住房将过大地挤占年轻人的生活支出,而房子给年轻人带来的生活满足感又或许已经不如以往。

 免疫检查点(immune checkpoint)这个词从文献上看,最早应该是出现在2006年Korman,Peggs和Allison的一篇综述文章上(10)。如今这个名称已是包罗万象,概念不仅远超出CTLA-4,还包括了PD-1/PD-L1以及后续所有其他对免疫反应有抑制作用的分子。如上所述,CTLA-4的免疫抑制作用是由Bluestone所发现,而且之前的文献对这一类有免疫抑制作用的细胞表面蛋白已有许多类似的描述,我也曾造出一个名词“共抑制”(coinhibition)来描述这个现象(11),但这些名词都没有火起来。为啥“免疫检查点”就能火起来呢?这个就和怎么宣传有关系了。也就是我下面还要说的话语权的问题。

"It improves the effectiveness of the governing bodies and allows China to adapt to changing times."

 "For example, the people are paying more and more attention to intellectual property, so it's a good idea to adjust this department," she said.

 The strategic defense and security review of 2015 set increased targets for many intelligence analyst roles, with some in the Royal Air Force being doubled or even trebled. The nature of newly-emerging threats means intelligence demands, such as language skills, can change rapidly, making training particularly challenging.
