【分析】他把物理学和幽默紧密地联系在一起．
【解答】1． A．主旨大意题．本文 主要写了著名的科学家霍金在自己生病后用科学的幽默来对待自己的生活，他把物理学和幽默紧密地联系在一起．所以A选项符合主旨．故选A．
2． C．推理判断题．根据第二段句子：he recounts how，in 1277，the Catholic Church declared scientific laws such as gravity to be wrong，since they seemed against God's idea．他叙述了1277年天主教会如何宣布重力等科学定律是错误的，因为它们似乎违背了上帝的想法．教皇是反对万有引力定律．所以答案选C．
3． A．推理判断题．根据倒数第二段句子：\，他喜欢冒险和乐趣，可以推断是冒险精神驱使霍金走上彗星的．所以选A
4． B．推理判断题．根据倒数第一段句子Maybe one day someone living in the future will find the information and use a wormhole time machine to come back to my party，proving that time travel will one day be possible也许有一天生活在未来的人会找到信息，用虫洞时间机器回到我的聚会上，证明有一天时间旅行是可能的．可知时间旅行的可能性没有得到证实．所以选B．

gives bread much of its appealing texture is gluten，a group of proteins found in wheat．But in people with celiac disease（乳糜泻），gluten damages the small intestine（肠）．Many others may have milder gluten intolerance and avoid foods that contain it．
Most gluten﹣free bread is made from alternative flours such as rice or potato，so it tastes and feels different from wheat bread．Now，however，researchers say that they have found a way to genetically engineer wheat that contains far less of the most troublesome type of gluten﹣but still has other proteins that give bread its characteristic taste and springiness．
Genetically modified crops are the subject of fierce debate around the world．The biggest concern involves the practice of inserting DNA from one species into another，says Francisco Barro，a plant biotechnologist．To avoid this genetic crossover，Barro and his colleagues used the gene﹣editing technique CRISPR/Cas9to cut selected genes from a wheat genome（基因组）．
Their study zeroed in on alpha﹣gliadins（α﹣胶质蛋白），gluten proteins believed to be wheat's major troublemakers in the immune system．The researchers designed bits of genetic material that directed the scissor﹣like Cas9 protein to cut out 35 of the 45 alpha﹣gliadin genes．When the modified wheat was tested in a Petri dish，it produced an 85 percent weaker immune response，the team reported online last September in Plant Biotechnology Journal． Wendy Harwood，a crop geneticist at the John Innes Center in England，who was not part of the study，notes that the engineered wheat has a long way to go before it can be turned into anything marketable．\．\．\important step in maybe producing something that is going to be incredibly useful．\a completely safe strain of wheat for celiac patients，the researchers may need to target more of the gluten genes．Barro says his team is working on that．

【解答】1．D．主旨大意题．本文主要介绍研究发现了发展转基因小麦的优点以及专家对此的看法．因此开发基因工程小麦符合标题，故选D．
2．B．推理判断题．根据第一段中What gives bread much of its appealing texture is gluten，a group of proteins found in wheat．But in people with celiac disease（乳糜泻），gluten damages the small intestine．让面包如此吸引人的是谷蛋白，是在小麦中发现的一组蛋白质，而对乳糜泻患者，谷蛋白损害小肠．然后下文就写了转基因小麦可以解决这一问题，因此写面包是为了引出话题，故选B．

You not only have high standards for yourself but you also have them for others．If people don't perform up to your expectations，then you think them incompetent．This causes a lot of frustration because you can't trust anyone to get things right．So instead of being a team player you fly solo（单飞）and try to do two or three jobs at once．Your unrealistic expectations cause you to criticize and judge others and that leads to problems in other areas of your life． The attempt to be perfect is called perfectionism and it's the unachievable American dream that's damaging our emotional and mental health．We strive for perfection with our body，in our performance，and in our relationships．In a society that overstates mistakes，is it any wonder that so many young people attempt the impossible task of being perfect？
