Microplastics are some of the Earth’s tiniest and 【小题1】 (harm) enemies. 【小题2】new study reveals that microplastics have even polluted Alpine snow and Arctic ice. How did the microplastics get there? The study,【小题3】 (publish) this week in the journal Science Advances,assumes that the tiny particles become airborne and, when 【小题4】 (sweep) up into the Earth’s atmosphere, can be transported virtually around the globe. If microplastics 【小题5】(find) in original Arctic ice, they’re probably being breathed in, lived in and eaten by animals in other ecosystems.【小题6】 microplastics are being swirled around the atmosphere, the study says, we’re breathing 【小题7】in, as well. And that could have serious health 【小题8】 (consequent).“The high MP concentrations detected in snow samples from continental Europe to the Arctic indicate significant air pollution and stress the urgent need for research 【小题9】 human and animal health effects 【小题10】 (focus) on airborne MPs,” the study says.

How good are you at maths? Some people love algebra or enjoy number【小题1】(puzzle) such as Sudoko. Maths is around us; try working out how to split the bill after a meal, 【小题2】 cafculating your household bills. But many are scared of the moment when they have to deal with numbers and feel a real sense of 【小题3】 (confuse). It can seem scary, but this“maths anxieh” is too common to be neglected.

【小题4】 problem starts in childhood at school. So far, researchers 【小题5】 (find) that maths teachers【小题6】 are-nervous about teaching the subject can pass on their worry to pupils, and girls may be more likely to be affected. Around 31% of 15 and 16-year-olds across 34 countries said they got very nervous doing maths problems. Shulamit Kahn, from Boston University’s Questrom School of Business, told the BBC she believes giving students【小题7】(especial) girls, good role models 【小题8】 (be) important at a young age”.

Writing for BBC Future, David Robson says “It’s not clear why maths arouses (激发) so much fear compared to geqgraphy. But the fact that there’s a right or wrong answer might make you more【小题9】(worry) about underperforming.” And once we think we’re not a “maths person”, we avoid 【小题10】(solve) things we probably could do.

When we think of the most respected awards in the world, the Nobel Prize must be on 【小题1】 list. Created by Swedish inventor Alfred Nobel in 1895, the prize recognizes achievements in sciences and the people behind them, 【小题2】 (encourage) the young generation to engage in 【小题3】 (science) research and cultural creation. Every year in October, the announcement of winners catches the world’s attention.

But what is the importance behind this award?According to founder Nobel 【小题4】 (he), the prize is for people who have provided “the greatest benefit to humankind”.A number of Nobel Prizes have rewarded discoveries 【小题5】 have led to cures for diseases and health problems. Numerous components in telephones, computers and telecommunication systems are 【小题6】 (true) the fruits of Nobel Prize-awarded work. Other prizes have recognized those who have helped to create a more peaceful world.

The individuals 【小题7】 (select) and the contributions they made show how science, literature and peace efforts improve and change the world and better our lives. Think about the plastic bags in supermarkets. Plastic wouldn’t have been invented 【小题8】 Friedrich Wilhelm Ostwald’s research on catalysis (催化作用). The German scientist won the Nobel Prize in 1909.

In recent years, Chinese people 【小题9】 (pay) more attention to the results of the Nobel Prize, following many prizes’ uplifting 【小题10】 (recognize) of Chinese scientists and writers, such as 2012 Nobel literature prize winner Mo Yan, and Tu Youyou, China’s first Nobel winner in physiology or medicine in 2015.
