4 . Plastic is everywhere, from the Arctic ice to vital organs in the human body. In fact, previous estimates suggest that the average person swallows a credit card-worth of microscopic plastic particles(颗粒) every week. But new research shows that this could actually be an understatement.

Microplastics are plastics smaller than 5 millimeters, found in industrial waste, beauty products, and formed during the degradation of larger plastic pieces. Over time, they break down into even smaller nanoplastics. These tiny particles can pass through our intestines and lungs into our bloodstreams, reaching vital organs like the heart and brain.

While the idea of eating plastic is unsettling in itself, the major concern here is that these plastic particles contain chemicals that can interrupt our body’s natural release of hormones, potentially increasing our risk of reproductive disorders and certain cancers. They can also carry toxins(毒素) on their surface like heavy metals.

In the past, researchers have shown bottled water can contain tens of thousands of identifiable plastic fragments in a single container. However, until recently, only the larger microplastics were detectable with available measuring tools, leaving the area of nanoplastics largely a mystery.

Using Raman microscopy (显微镜学), capable of detecting particles down to the size of a flu virus, the team measured an average of 240, 000 particles of plastic per liter of bottled water, 90 percent of which were nanoplastics, a revelation 10 to 100 times larger than previous estimates.

These plastics likely originate from the bottle material, filters used to “purify” the water, and the source water itself. “It is not totally unexpected to find so much of this stuff, ” the study’s lead author, Columbia graduate student Naixin Qian, said in a statement. His team hopes to expand their research into tap water and other water sources to better inform our exposure to these potentially dangerous particles. “The idea is that the smaller things get, the more of them I reveal, ” he added.

8 . Future living: what will the home of tomorrow look like?

What will our homes be like in the future? Growing cities, shrinking living spaces, and climate change are major challenges     1    (face) urban planners and architects. We’re sharing three trends with you     2     will shape the home we live in tomorrow.

Energy efficient and carbon neutral

One of the greatest challenges for homes of the future is our increasing energy consumption, something that cannot be covered by fossil fuels going forward.     3    the impact of climate change becoming notable, it’s perfectly understandable that the buildings of the future could function as environmentally friendly power plants. Solar collectors and heat storage systems allow     4     are known as ‘plus-energy buildings’ to produce 100 percent renewable energy for emission-free operation.

The trend to downsizing

Living more efficiently not only means improving energy use and reducing one’s own carbon footprint, but also building to save space. Rooms     5    (design) to be multifunctional when there’s not a dedicated room available for every potential purpose. Modular and flexible furnishing systems that can be adapted to the individual floor space and room zones will replace     6    (fix) structures, ensuring that there’s room for everything even in a small space.   

Trends for living and working under one roof

Over the last few months, the office     7    (become) a feature in many people’s homes. For a number of years now, the home office has been evolving from a make-do desk into a comfortable long-term solution. This development means we need to ask     8     how we should construct our living spaces to allow us to concentrate and work productively.   

    9     you rent or own your own home in the future, what’s clear is that the home of tomorrow will be smarter, more flexible, and more sustainable. It will offer us space     10    (live), sleep and work both indoors and outdoors.

9 . What Makes a Nobel Laureate?

Are there any predictors that point to who will be selected as Nobel laureates?

Is brilliance in childhood a predictor? When the 2006 chemistry laureate, Roger Kornberg, was asked what he wanted for Christmas, he said, “A week in the lab.”     1    . Mario Capecchi (medicine, 2007) was an abandoned child on the streets of wartime Italy.

    2    . Five of Enrico Fermi’s (physics, 1938) postdoctoral students went on to win the Nobel Prize. Otto Warburg (medicine, 1931) advised an American doctoral student, “If you wish to become a scientist, you must ask a successful scientist to accept you in his laboratory.”

Experts often recommend that people specialize in one field of work or research to maximize their chances of success.     3     If you look at the careers of Nobel Prize winners, you’ll find that they are unusually likely to be “creative polymaths.” That is, they purposely integrate formal and informal expertise from widely varied disciplines to yield new and useful ideas and practices.

There remains one quality that is essential. It is what Leon Lederman (physics, 1988) called “compulsive dedication.”     4    . Take Marie Curie (physics, 1903; chemistry, 1911) and her husband Pierre (physics, 1903). The Curies were assigned a shed with a leaking roof and a dirt floor, where they worked for years, freezing in winter and sweltering in summer. “And yet,” Marie Curie wrote in her biography of her husband, “it was in this miserable old shed that the best and happiest years of our life were spent, entirely dedicated to work.”

A．What distinguishes Nobel laureates is passion for their work, work that engages their hearts as well as their heads.

B．But early privilege is not essential.

C．The typical Nobel laureate in science is a male born into a middle-class family.

D．In many Nobel laureates’ autobiographies, they pay tribute to an outstanding mentor.

E．In fact, Nobel laureates are mostly down-to-earth and discreet.

F．Yet recently published researches indicate that successful innovators take a broader path.

10 . Our culture has caused most Americans to assume not only that our language is universal, but that the gestures we use are understood by everyone. We do not realize that waving good-bye is the way to ask a person from the Philippines to one’s side, or that in Italy and some Latin-American countries, curling the finger to oneself is a sign of farewell.

Those private citizens who sent packages to our troops occupying Germany after World War II and marked them GIFT to escape duty payments did not bother to find out that “Gift” means poison in German. Moreover, we like to think of ourselves as friendly, yet we prefer to be at least 3 feet or an arm’s length away from others. Latins and Middle Easterners like to come closer and touch, which makes Americans uncomfortable.

Our linguistic and cultural blindness and the informality with which we take notice of the developed tastes, gestures, customs and languages of other countries, are losing us friends, business and respect in the world.

Even here in the United States, we make few compromises to the needs of foreign visitors. There are no information signs in four languages on our public buildings or monuments; we do not have multilingual guided tours. Very few restaurant menus have translations, and multilingual waiters, bank clerks and policemen are rare. Our transportation systems have maps in English only and often we ourselves have difficulty understanding them.

When we go abroad, we tend to cluster in hotels and restaurants where English is spoken. The attitudes and information we pick up are conditioned by those natives—usually the richer—who speak English. Our business dealings, as well as the nation’s diplomacy, are conducted through interpreters.

For many years, America and Americans could get by with cultural blindness and linguistic ignorance. After all, America was the most powerful country of the free world, the distributor of needed funds and goods.

But all that is past. American dollars no longer buy all good things, and we are slowly beginning to realize that our proper role in the world is changing. A l979 Harris poll reported that 55 percent of Americans want this country to play a more significant role in world affairs; we want to have a hand in the important decisions of the next century, even though it may not always be the upper hand.

1. It can be inferred that Americans being approached too closely by Middle Easterners would most probably________.

A．stand still
