In my opinion, we are living on borrowed time. We have 3 or 4 days" worth of food in the city. And if that food supply is disrupted, we"ll be in a lot of trouble. We should have something in the city that replaces this very tenuous food supply and it should be growing in the city. The bulk of the world"s population are going to be urban and are going to be living in high-rise accommodation. How do you make sustainable living solutions for the real world By the year 2050, over 3/4 of the world"s population is expected to live in cities. The trend towards urbanization is greater now than at any time in history. And as population grows, it poses a unique problem: how best to grow food and supply it to the cities We are looking at the exciting and unconventional field of agriculture, that is vertical farming. It could radically change the view across the Thames here in London. 注释： (1)disrupt v. 分裂，破坏 (2)tenuous a. 薄的，细的 (3)bulk n. 大量，大批，the bulk of大半，大部分 (4)accommodation n. 泛指房间，住所accommodate v. 向……提供住处 (5)urban a. 都市的，在都市的urbanization n. 城市化，urban加后缀-ize变动词，表示……化，在此基础上加后缀-ation变为名词 (6)sustainable a. 可持续的sustain v. 后缀-able有被动之意 (7)trend n. 倾向，趋势 (8)pose n. 造成，提出 (9)unconventional a. 非传统的，非惯例的，由conventional加前缀un-构成 (10)vertical a. 垂直的，直立的vertical farming垂直农业
Our hypothesis is that immigrants, who often do not speak the language and do not master the culture and norms of the host country, are concentrated in more manual-routine tasks (especially among less educated groups). The inflow of immigrants thus increases the supply of manual skills relative to the supply of abstract skills with two effects: ● Due to the complementarity between these types of skills, the increase in the supply of manual tasks boosts relative compensation for complex skills, making them better paid. ● Exploiting their comparative advantage, natives move to occupations requiring a relatively higher level of these skills. This positive reallocation and the complementarity of tasks can explain the lack of negative employment effects as well as the potential positive wage effects of immigration on native workers. So here"s how it all shakes out. Low-skilled immigration reduces economic inequality when we set aside nationalist assumptions and focus on people instead of populations. Even if we cling to analytical and moral nationalism, low-skilled immigration doesn"t happen to increase measured inequality. On the contrary, complementaries between the skills of migrant and native workers can leave natives better off than they would have been with less immigration. 注释： (1)hypothesis n. 假设 (2)account for动词短语固定搭配，解释……的原因 (3)positive a. 积极的/正面的negative a. 消极的/反面的 (4)host a. 主人，主持host country在文中指移民寄居国 (5)boost v. 向上推，推起 (6)reallocation n. 重新分配allocate v. 分配，配给 allocation n. 前缀re-，有“重新、再”的意思 (7)complementarity n. 互补性 complementary a.

Two to three times more people die in alcohol-related vehicle crashes during that time than during comparable periods the rest of the year, the National Institute on Alcohol Abuse and Alcoholism says. And 40% of traffic fatalities during winter holidays involved an alcohol-impaired driver, compared with 28% for other dates in December. Fueling the underage drinking problem, especially at this time of the year, is "a combination of greater access to alcohol, less parental oversight and mixed messages" about celebrating with alcohol, Delany says. Young people are told "don"t drink, don"t do that, but in every third commercial in recent weeks, we see something linked to alcohol and drinking," he says. And there"s also the issue of "what kind of message parents may give," Delany adds. "Maybe they"re drinking a lot. Kids see that it"s OK." What is needed is a long-term message "that underage drinking is not OK," he says. "But adolescents don"t do well with "Just say no." We have to find ways to help young people make good decisions." 注释： (1)comparable a. 由词根compare v. 变化词尾而来，英语后缀-ble，-able变化的形容词都有被动含义，翻译时可考虑译成动词 (2)fatality n.(由意外或灾祸导致的)死亡 (3)alcohol-impaired由连字符连接的合成词连字符前后没有修饰关系，impaired为过去分词，有被动意，可翻译成“酗酒导致的” (4)combination n. 结合 v. combine结合 (5)commercial n. 商业广告，由commerce一词变化而来 (6)adolescent n. 青少年 (7)oversight n. 失察、疏忽和小心照顾，根据语境这里取小心照顾之意
