    Ever since the University of Bologna in Haly was founded in 1088 as the first modern university, most people have associated great universities,with major cities.1.

Colleges and universities in the U.S.,though, have followed a different pattern. To be sure, leading universities such as the University of Chicago and Columbia University in New York City call major urban centers home.2.In some cases, the university is, for all practical

purposes, the whole town.

3. Many early colleges and universities were founded by religious (宗教的) groups that sought to educate students far from the distractions of city life. When Harvard University was founded in 1636 by Congregationalist Church ministers, Cambridge, where the university is now located, was quite separate from Boston. Moreover, when the U.S. began building a network of public universities in the 1860s to bring agricultural and technical research and know-how to the westward- spreading frontier, most were located in small towns. 4.

Given the huge diversity of U.S. higher education, the message for international students shopping for a great university is doubled.5.Don't be put off if you have never heard of the city or town where a school is located. Top-rated colleges and universities located in lesser

known places may amaze you in an unimaginable manner with their high quality and a significant number of their international students.

A.Bloomington is also a great college town.

B.Think the Sorbonne in Paris or Peking University.

C.Set your sights beyond the most well-known schools.

D.One reason: there were no major cities there at the time.

E.There was no better recipe for popularity than small campuses.

F.Part of the explanation for this lies in America's distinctive history.

G.But many are located in cities and towns most people have never heard of.

    Over the last 25 years, psychologists have found that personalities center on five basic traits(特性) — the Big Five: agreeableness, conscientiousness (责任心), neuroticism, extroversion and openness. Contrary to common belief, people just aren’t organized into certain personality types. Every trait is a continuous dimension and everyone can be described as having varying levels of each trait. A new research has also found animals from ants to apes all have the Big Five and that the universality of personality points to an evolutionary (进化) origin.

Animals and humans have common problems of survival, which are spelled out beautifully in the Big Five, and that’s why there’s so much continuity in human personality and animal personality. For example, conscientiousness involves behaviors like planning and consideration, which are important among animals for taking care of their young, selecting mates and living in groups. Being neat and orderly — aspects of conscientiousness-also has evolutionary superiority. Bees that like to keep clean and remove more dead group members reduce risk of disease, gain more weight and reproduce more Spiders that make tidy webs catch more insects. Birds that build neater and solider nests attract more mates.

These behaviors may seem primitive, but they’re nevertheless indications of personality. Personality is the expression of all of the behaviors that humans and animals exhibit that allow them to function adaptively in the world.

Evolution can also explain why personalities vary so much. Depending on the situation, each of the Big Five can be advantageous. For example, agreeableness is great for relationships. But if a lion were charging at you, you’d be better off with a less agreeable and more aggressive personality. Because the world is so unpredictable, every aspect of each personality trait could be useful at different times, so instead of evolving a single type of personality that’s best for every situation, we’re left with a wide variety.

    The Tokyo Summer Olympics is going green. The 5,000 medals Japan has made are more special than most.

One novel focus of the Tokyo Olympics is to be“sustainable”—to avoid using too many natural resources, so that the games are easy on the environment. As part of this goal, the organizers decided to make all of the Olympic medals out of metal recycled from old electronics.

Almost all electronics are made with small amounts of "precious metals", like gold and silver. But collecting enough of these metals to make 5,000 medals was a huge challenge. That's because the amount of metal in each device is tiny. It would take about 20,000 cell phones to get just 1 kilogram of gold.

Beginning in April 2017, the organizers placed collection boxes around the country, and asked people to turn in their old electronic devices. Soon people began to respond to the initiative, turning in smartphones, digital cameras, hand-held games, and laptops. At first, collection went slowly, but soon more and more areas began to take part. By the end, 1,621 local governments had helped out with the collection process.

Then came the job of breaking those devices down into smaller pieces. After being taken apart and sorted, the small electronics were smelted (熔炼) to get all the gold, silver, and bronze elements. This is a tricky job, which calls for careful attention and good skill. It's also dangerous, because some of the metals and other things aren't safe for people to touch or breathe.

By the end of March, 2019, the organizers had hit their targets of getting enough metal for the medals. They had collected around3xkilograms of gold, 4,100 kilograms of silver and 2,200 kilograms of bronze. And now all the 5,000 medals are available for the would-be winners.
