3、nd a chance to revolutionize a major environmental issue. Burds strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms(微生物)If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions. With

4、this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growthThen he added the plastic powder and let the microbes work their magic for 3 monthsFinally, he tested the resulting bacterial culture on

5、plastic bags, exposing one plastic sample to dead bacteria as a controlSure enough, the plastic exposed(暴露) to the live bacteria was 17% lighter than the control after six weeks. The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work

6、, and the only outputs are water and tiny levels of carbon dioxide. “Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of meOne day, I got tired of it and I wanted to know what other people are doing with these plastic bagsThe answer:

22、 (念一句话). A human who says that science is fun is telling you something important about being alive. Heres another inbuilt advantage we take for granted: as humans we are limited by design.

24、stopped people from inviting me to speak in person. Digital Alan seems to increase the appetite for human Alan, just as Spotify (a digital music service) can increase the demand for a musicians live performances.

27、ed him, bullied him, and smacked (掌击) him in the head. The point is not that the children were violent. The point is that the adults were not. They restrained whatever primitive impulse (冲动) they might have felt in childhood to smack something smaller and weaker in the head, because they had absorbe

28、d the habit of living together. We call it civilization. If we want artificial intelligence for the people, well need every bit of that civilizing instinct.

Althoug

32、h he might shed a tear at a funeral, he is expected to quickly regain control. Sobbing openly is for girls. One study found that women cry significantly more than men dofive times as often, on average, and almost twice as long per period. Historically, however, men routinely wept, and no one saw it

33、as shameful. For example, in the Middle Ages, knights cried purely because they missed their girlfriends. In The Knight of the Cart, no less a hero than Lancelot weeps at a brief separation from Guinevere. Theres no mention of the men in these stories trying to restrain or hide their tears. They cry
