A seed bank stores seeds to preserve genetic diversity; hence it is a type of gene bank. Many people may wonder 1 the seeds are stored. One of the major reasons is to preserve the genes that plant growers need to increase yield (产量), disease resistance, drought tolerance, nutritional quality, and the taste of crops. Another is to prevent 2 (lose) of genetic diversity in rare or endangered plant species in 3 effort to conserve biodiversity. Many plants 4 (grow) centuries ago by humans are used less frequently now; seed banks offer a way to preserve that historical and cultural value. Collections of seeds stored 5 constant low temperature and low water level are guarded against reduction of genetic resources which are otherwise maintained in field collections. These alternative “living” collections can 6 (damage) by natural disasters, outbreaks of disease, 7 war. Containing valuable information about evolved strategies to reduce plant stress, seed banks are considered seed 8 (library), and can help to create genetically modified (调整过的) versions of 9 (exist) seeds. The work of seed banks often span decades and even centuries. Most seed banks are 10 (public) funded and seeds are usually available for research that benefits the public.

Now that the temperature is heating up, do you find yourself 1 (stare) at a sea of clothes in your cupboard, wondering what to wear? You may have a lot of choices, but which one is the 2 reasonable?

The idea of wearing dark clothes doesn’t make sense as heat hungrily goes into the clothes and 3 (cause) you to suffer a lot. But white clothes will lightly return the heat right off, and you’ll be more comfortable on a hot day.

4 it certainly sounds great in theory, there are a few other factors at play that might be working against the old saying about the light clothes. At the very least, there’s some 5 (convince) evidence that says it doesn’t matter. Let’s start with some 1980 academic research from the journal “Nature,” titled “Why do Bedouins (贝都因人) wear black robes (长袍) in hot deserts?”

The researchers, 6 you can guess, were as confused as you and I by the fact that in serious heat, the people of the Sinai desert wear black robes instead of white. 7 they found was that the differences were zero when they tested white robes versus black.

They found that the black clothes did collect more heat, but that’s 8 it stayed. In other words, the black clothes take 9 additional heat, but that extra is lost by the time it actually gets to your skin. Is there a way more useful for keeping cool, however? The robes are loose to allow air to move.

There’s also an argument that the whole “light clothes” argument is missing a key element: the person who’s wearing the clothes. This means that the heat your body gives out will actually reflect off white clothing, returning to your body 10 (keep) you comfortably warm. Not a bad theory, but it’s not tested on humans.

文章大意：本文是一篇说明文。文章讲述了美国的一项新的研究发现：在遗传学方面，没有生物学关系的朋友仍然倾向于彼此相似，该研究证明“朋友是你选择的家庭”。

【推荐2】阅读下面短文，在空白处填入1个恰当的单词或括号内单词的正确形式。

Friends who are not 1 (biological) related still tend to resemble each other when it comes to genetics, according to a U. S. study 2 (publish) recently that proves that “Friends are the family you choose.”

“ 3 (look) across the whole genome (基因组), we find that, on average, we are genetically similar to our friends,” lead author James Fowler, professor of the University of California, San Diego, says. “We have more DNA 4 common with the people we pick as friends than we do with strangers in the same population.”

On average, friends are as “related” as fourth cousins or people who share great, great, great grandparents, 5 translates to about one percent of our genes. One percent may not sound like much to the layperson (外行). “But to geneticists it is a 6 (significance) number. And how remarkable: Most people don’t even know who their fourth cousins are! Yet we are quite likely 7 (select) the people who resemble our relatives as friends.”

One of the most interesting 8 (discovery) in the study is that genes more similar between friends seem to be evolving faster than other genes. This may help explain why human evolution 9 (quicken) over the past 30, 000 years, which suggests that the social environment itself is 10 evolutionary force.
