One of the most important battles in any home is for the TV remote. Whoever gets it has the________over what is watched. But after reading this article, your interest in winning the________for the remote may fall, as a study has shown that the remote is pretty________.

The toilet is always a good surface for________. During the study, researchers ________that a toilet had 12.4 colony-forming units (菌落形成单位) per cm² ________the TV remote had 290 colony-forming units per cm. The TV remote was the ________item tested by far. It makes________. How often have you seen someone clean the TV remote and how often are dirty hands________ it?

Many people are now able to________their TV from their smartphone or smartwatch. This may________the dynamics of the fight for the remote but it won’ t ________ it. If the battle does move to smart________, the bacteria (细菌) issue doesn’t disappear. While both smartphones and smartwatches appeared to be cleaner than the remote, they are________far from clean.

If you want to ensure that your home is ________of high amounts of bacteria, throwing out the remote is not the ________ . You need to have a________that ensures the house is clean but that the things you________most are also clean. Hopefully, this latest study can________ some action in your home and cause people to________ the importance of washing their hands regularly and cleaning common surfaces.

文章大意:本文是一篇说明文。文章主要讲的是一个研究小组声称,在理解软体动物可能形成的最简单的记忆方面取得了进展,并且通过快速注射,成功地将一只海螺的记忆转移到另一只海螺身上。

【推荐1】Science may never know the secrets to memories of the California sea hare, a foot-long sea snail. But a research team claim to have made progress in _______ the simplest kind of memory a mollusk (软体动物) might form, and, with a swift injection, managed to _______ one sea snail’s memory to another.

The kinds of memories that start a defensive reaction in the snails are encoded not in the _______between brain cells, but in RNA molecules (分子), according to David Glanzman, a biologist at UCLA. To _______ the idea, Glanzman implanted wires into the tails of California sea hares and gave them a series of electric shocks. The procedure made the animals so _______ that when they were touched, they contracted parts of their bodies intensely. Glanzman compares the reaction to being nervous after an earthquake: the memory of the event causes a(n) _______ response to any loud noise. After sensitizing the sea snails, Glanzman took RNA out from them and _______ it into new sea snails to see what would happen. He then found the new ones are _______ sensitized, suggesting the “memory” of the electrical shocks had been transplanted. According to Glanzman and his research team, the experiment shows that _______ parts of the memory trace are held in RNA, rather than in the connectivity of brain cells.

However, the work has not yet found widespread ________. “Further work needs to be carried out to determine whether these phenomena are obvious and what is the ________ of such phenomena,” said Prof Vann at Cardiff University. “While a sea snail is a fantastic model, we must be very ________ in drawing comparisons to human memory processes, which are much more complex.”

Tomás Ryan at Trinity College Dublin, is ________. “This work takes us down an interesting road, but I have doubt about it and I don’t think they’ve transplanted a memory,” he said. “This work tells me that maybe the most basic behavioral responses involve some kind of change in the animal.”


________, Ryan added that such creative thinking about memory was in great need: “In a field full of acceptance but lacking ________, we need as many new ideas as possible.”1.

【推荐2】A study from Switzerland’s Université de Genève(UNIGE) looked to answer the question of which came first: a decrease in physical activity or cognitive (认知的) decline?

“Interrelationships have been ________ between these   two   factors,   particularly   in   terms   of memory but also regarding the growth and survival of new neurons (神经元).” said Boris Cheval, a researcher at UNIGE’S Swiss Centre for Affective Sciences (CISA) in a press release. “But we have never yet ________ tested which comes   first: Does   physical activity   prevent a decline in cognitive skills or ________ ? That’s what we wanted to ________ .”

Earlier studies have considered that physical activity ________ cognitive decline.   But according to Cheval, recent studies may ________ that past research has “only told half the story… since those   recent studies demonstrate that our brain is ________ when it comes to engaging in physical activity.”

Researchers at UNIGE tested the two possible ________ by using data from the Survey of Health, Aging and Retirement in Europe, a socioeconomic database covering more than 25 countries across the continent.

Over the course of 12 years, 105, 206 adults _______ in age from 50 to go were tested every two years on their cognitive abilities and their physical activity.

Researchers ________ cognitive abilities with a verbal fluency test that saw participants name as many animals as they could in 60 seconds. They also tested cognitive abilities with a ________ test where they memorized 10 words before reciting them. Physical activity was measured using a scale from 1 to 4. A 1 indicated participants “never” ________ physical activity while a 4 meant they were physically ________ “more than once a week”.

The study found that the ________ of what past studies concluded was true ― cognitive abilities mostly influence physical activity, not the other way around.

“This study backs up our theory that the brain has to make a real effort to get out of a sitting lifestyle and that by _______ cognitive capabilities, physical activity will follow,” Cheval said.

文章大意:这是一篇说明文。文章主要讨论了数学是否也存在美的问题,作者认为尽管在哲学、心理学和教育等多个领域都在研究数学美的本质,但仍有许多悬而未决的问题。一旦你意识到数学除了它的科学价值之外,本质上还是一门美学学科,你就会意识到,把数学教给学生而不传达它的美,可能会失去这门学科的本质,失去这门学科的生命。

【推荐3】It is a human nature to hunt for what is beautiful, and we do so because beauty is appealing. I hold that the same is true of mathematics. Beauty -- or aesthetics (美学) more generally--is not just a by-product of the _____. It isn’t that you look back at the end of day and notice that a proof or definition is beautiful. It seems to be that beauty is an essential part of the _____.

This is not to say that all mathematical work is beautiful. Some proofs are boring and long. Some require computer code and are difficult to check. And it is not clear that aesthetic experiences are _____.What is beautiful to a geometrician might not be to an algebraist. What was beautiful to you as a graduate student might not be after 20 years of research.

Although research on the nature of mathematical beauty is under way in several fields--such as philosophy, psychology and education--there are still many _____ questions. What do we mean by beauty? Is it objective or subjective? Can equations be beautiful in their own right, or must they be connected to some sort of visual or sensory _____?

Answers are beginning to _____. For example, a recent study led by Semir Zeki at University College London involved scanning the brains of mathematicians while they viewed different formulae (公式), such as Euler’s identity, e+1=0, an equation rated as beautiful by the participants. The scans showed that the _____ of mathematical beauty excited the same area of the brain as music or art.

Whatever we mean by the term “mathematical beauty” and how we judge it, there is no doubt that aesthetics plays a significant role in the working life of mathematicians._____, it is not obvious whether the beauty of mathematics can be conveyed at the school level, but this question is not one that has _____ a great deal of attention. _____ tend to be centred on a standard set of mathematical topics and processes. There has been little discussion of aesthetics, despite its _____ potential. A leading journal, Educational Studies in Mathematics, called mathematical aesthetics one of the most under-researched areas in the field.

The question for school mathematics is simply this: do we teach it without conveying its true _____? Teaching maths just in terms of procedures such as practising sums is like teaching music through practising scales without ever _____ children to Beethoven.

When experiencing a moment of true mathematical understanding--_____ why something is so, or seeing how everything hangs together--you can feel a sense of meaningfulness, connection and purposefulness, just as you might with poetry or music.

Once you realise that mathematics is, in addition to its scientific values, an essentially aesthetic subject, you realise that teaching it to students without conveying its beauty might be to _____ the essence, the very life, of the subject.
