I. 阅读理解
There are many gardening tips. Some suggest playing music for your houseplants, having conversations with them, or even giving them a gentle touch now and then. Most of these practices are probably more for the benefit of the gardener than the garden, and generally harmless enough but except the last one. Your plants really dislike it when you touch them.
A new study out of the La Trobe Institute for Agriculture and Food has found that most plants are extremely sensitive to touch, and even a light touch can significantly stunt (遏制) their growth. “The lightest touch from a human, animals, insects, or even plants touching each other in the wind, can cause a huge gene response in the plant,” Jim Whelan, who led the new study, said. “Within 30 minutes of being touched, 10% of the plant’s genome (基因组) is changed. This involves a huge expenditure (消耗) of energy which is taken away from plant growth. If the touching is repeated, then plant growth is reduced by up to 30%.”
Whelan and his team are still trying to find out why plants respond, at the genetic level, so strongly. They do have some theories, however. “We know that when an insect lands on a plant, genes are activated (激活) preparing the plant for defending itself against being eaten,” said Dr. Yan Wang, coauthor of the study.
Until more research is done, it’s just a guess at this point. Still, the findings might already lead to new methods for how agriculturalists deal with their crops, to best promote healthier growth.
It’s worth noticing that while the study found that plants often respond to just a single touch in negative ways, it’s really repeated touch that causes lasting stunted growth. That’s because the plants are looking for patterns in the touching, to tell harmful touch from random touch. So it doesn’t matter if you accidently brush up against a bush during a walk through the woods.

B. It helps find ways to ensure plants’ healthy growth.
C. it contributes to the further study on genes.
D. it uses data to warn people not to touch plants.
4. What is the passage mainly about

Is Fresh Air Really Good for You
We all grew up hearing people tell us to “go out and get some fresh air”. 1 According to recent studies, the answer is a big YES, if the air quality in your camping area is good.
2 If the air you’re breathing is clean—which it would be if you’re away from the smog of cities— then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles (肌肉) and your brain.
Recently, people have begun studying the connection between the natural world and healing (治愈). 3 In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood (情绪). Greenery is good for us. Hospital patients who see tree branches out their window are likely to recover at a faster rate than patients who see buildings or sky instead. 4 It gives us a great feeling of peace.
5 While the sun’s rays can age and harm our skin, they also give us beneficial Vitamin D. To make sure you get enough Vitamin D—but still protect your skin—put on sunscreen right as you head outside. It takes sunscreen about fifteen minutes to start working, and that’s plenty of time for your skin to absorb a day’s worth of Vitamin D.
A. Fresh air cleans our lungs.
B. So what are you waiting for
C. Being in nature refreshes us.
D. Another side benefit of getting fresh air is sunlight.
E. But is fresh air really as good for you as your mother always said
F. Just as importantly, we tend to associate fresh air with health care.
G. All across the country, recovery centers have begun building Healing Gardens.

参考答案
I. ◎语篇解读 本文是一篇说明文，主要讲述了虽然我们平时很喜欢触摸植物，但是研究表明，植物真的不喜欢被触摸。
1. D
解析：细节理解题。根据第二段中的A new study out of the La Trobe Institute for Agriculture and Food has found that most plants are extremely sensitive to touch 和第三段中的 Whelan and his team are still trying to find out why plants respond 以及第四段中的 Until more research is done, it’s just a guess at this point. 可知，本文主要是通过展示研究成果来展开语篇的，故选D。
2. A
解析：细节理解题。根据第二段中的This involves a huge expenditure (消耗) of energy which is taken away from plant growth. If the touching is repeated, then plant growth is reduced by up to 30%. 可知，这包括从植物生长中带走的巨大的能量消耗。如果重复触碰，植物生长将减少30%。因此触摸会消耗植物的能量，故选A项。
3. B
解析：细节理解题。根据第三段中的Whelan and his team are still trying to find out why plants respond, at the genetic level, so strongly. （Whelan和他的团队仍在试图找出为什么植物在基因水平上的反应如此强烈。）及第四段Until more research is done, it’s just a guess at this point. Still, the findings might already lead to new methods for how agriculturalists deal with their crops, to best promote healthier growth.（在做更多的研究之前，此时这只是一个猜测，尽管如此，这些发现可能已经为农学家如何处理他们的作物带来了新的方法，以最好地促进更健康的生长。）可知Whelan和他的团队研究的重要性在于它有助于找到确保植物健康生长的方法，故选B项。
4. C
解析：主旨大意题。阅读全文尤其第一段中的Your plants really dislike it when you touch them. 可知，本文主要介绍了植物真的不喜欢被触摸，故选C项。
长难句分析
原句：It’s worth noticing that while the study found that plants often respond to just a single touch in negative ways, it’s really repeated touch that causes lasting stunted growth.
分析：本句为主从复合句。其中It为整个句子的形式主语，第一个that引导的主语从句作真正的主语；while引导让步状语从句，其中that plants often respond to just a single touch in negative ways 为宾语从句；it’s really repeated touch that causes lasting stunted growth 为强调句型，强调主语repeated touch。
句意：值得注意的是，虽然这项研究发现，植物通常以消极的方式只对一次触摸作出反应，但确实是反复的触摸导致了持久的生长发育迟缓。
【高频词汇】
1. for the benefit of 为了……的利益 2. generally adv. 一般，通常 3. harmless 无害的 4. sensitive 敏感的 5. significantly adv. 显著地，明显地 6. take away 带走 7. respond v. 回应，作出反应 8. defend v. 保护，防御 9. negative adj. 消极的，负面的，有害的 10. promote v. 促进，推动 11. random adj.随机的，随意的
II. ◎语篇解读 本文介绍了新鲜空气对人体的各种好处。
1. E
解析：根据下句中的the answer is a big YES可知，该空应该是一个一般疑问句，选项中只有E选项是一般疑问句。E项（但是新鲜空气真得像你母亲总说的那样对你有好处吗？）承上启下，故选E。空前的people tell us to “go out and get some fresh air”和选项中的your mother always said亦是呼应。
2. A
解析：根据下句 If the air you’re breathing is clean... the air is filled with life-giving, energizing oxygen. 可知，新鲜空气充满赋予人生命的，充满活力的氧气。再根据下文中more oxygen to get to your muscles (肌肉) and your brain （更多的氧气进入你的肌肉和大脑）可知是对前文的递进，故该空应该提到新鲜空气的基本作用，我们知道吸人的空气首先进人的是肺部，然后才会使我们的肌肉和大脑受益，故应选A项（新鲜空气清洁我们的肺部。）。
3. G
解析：根据下句中的these places可知，该空应该提到表示地点的复数名词。选项中只有G选项提到该类名词，these places 就是指Healing Gardens。
4. C
解析：前文介绍的是“康复花园”中的绿色植物对于病人康复的好的作用：绿色的、正在成长的植物可以减轻压力、降低血压、使人情绪良好；空后提到“它给我们一种平和感”。本空起承上启下的作用，说明处于“康复花园”这种自然环境中的好处，空后的It也要指代这种情况。故选C项（身处大自然可以使人精神焕发。）。
5. D
解析：根据下文中提到的the sun’s rays... give us beneficial Vitamin D可知，该段介绍阳光的好处。故本空应提到阳光。选项中只有D选项涉及阳光。故选D项（获得新鲜空气的另一个好处是阳光。）。
长难句分析
原句：If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles (肌肉) and your brain.
分析：本句为主从复合句。其中If引导条件状语从句；现在分词短语allowing even more oxygen to get to your muscles (肌肉) and your brain作结果状语，表示“自然而然”的结果。
句意：如果你在户外锻炼，你的身体会学会更深度地呼吸，甚至允许更多的氧气进入你的肌肉和大脑。
【高频词汇】
1. be away from 远离 2. be filled with 充满 3. life-giving adj. 维持生命的 4. breathe deeply 深呼吸 5. recovery n. 恢复，康复 6. turn out 结果发现…… 7. beneficial adj. 有益的 8. absorb vt. 吸收
