阅读理解

    Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease.But there is another factor that can cause your heart problems more immediately: the air you breathe.

    Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem, but two analyses(分析) now show that poor air quality can lead to heart attack or stroke (中风)within as little as a few hours after exposure.In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely(可能的) to suffer a heart attack within days of exposure than those with lower exposure.A separate study of stroke patients showed that even air that the U.S.Environmental Protection Agency (EPA) considers to be of “moderate” (良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

    The authors of both studies stress(强调)that these risks are relatively(相对的)small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure.However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices.So stricter regulation(规章制度)by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

(1)、The text mainly discusses the relationship between _______.
A、heart problems and air quality B、heart problems and exercising C、heart problems and smoking D、heart problems and fatty food
(2)、The underlined word “modest” in Paragraph 3 most probably means_________ .
A、relatively high B、extremely(极大地)low C、relatively low D、extremely high
(3)、What can we learn from the text?
A、Eating fatty food has immediate effects on your heart B、The EPA conducted many studies on air quality C、Moderate air quality is more harmful than smoking D、Stricter regulations on pollutants should be made.
(4)、The author's purpose of writing the text is most likely to________
A、inform B、persuade(说服) C、describe D、entertain(娱乐)
举一反三
阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    A new study, which was published in the American Journal of Preventive Medicine, found that heavy use of platforms such as Facebook and Snapchat was associated with feelings of being separated from society among young adults—basically the opposite of what we are led to believe.

    Study co-author Brian Primack and his team surveyed 1,787 U. S. adults aged 19 to 32 and asked them about their usage of 11 social media platforms. They also asked participants questions related to social isolation, such as how often they felt left out. The participants who reported spending the most time on social media—over two hours a day—had twice the odds of perceived(感知到的)social isolation than those who said they spent a half-hour per day or less on the same sites.

    According to Tom Kersting, psychotherapist and author of Disconnected, the key to understanding these results lies in our understanding of “connections.” “Humans are social —emotional beings, meaning that it is in our DNA to be connected, face-to-face, with other humans,” he told Reader's Digest. “Although people think being on social media all the time makes them 'connected' to others, they are actually 'disconnected,' because the more time one spends behind a screen, the less time one spend face-to-face.”

    “Part of the issue of loneliness is that the majority of people who use social media aren't just posting, they are also viewing,” Kersting continued. “They are spending a lot of time looking at everyone else's posts, where they are and what they are doing. The constant exposure to everyone else's 'perfect' life experiences causes feelings of being left out.”

    So what's the answer? It's simple, says Kersting. “The solution to this is resisting the temptation to look at everyone else's life. Just focus on your own life, where you're going, what you are grateful for, and what you want to accomplish in this world.”

    It seems that no one can live a happy life without friendship. While a great number of people expect others to be their friends, they don't give friendship back. That is why some friendships don't last long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.

    Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven't been honest, you may lose your friend's trust. Good friends always depend on one another to speak and act honestly.

    Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.

    Sooner or later everyone needs understanding and help with each other. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend's place so that you can understand the problem better.

    No two friendships are exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.

    “Sorry seems to be the hardest word”—that is one of Elton Johns most popular songs. But not every public figure seems to find it so tough to say that powerful five-letter word.

    In recent days public figures, from politicians to stars, have all publicly expressed remorse. But with so much remorse, how can we tell a forced apology from a heartfelt expression of remorse?

    Specifically, saying sorry should be a realization that something you have said or done has hurt someone and you want to make amends. “People wants the response to be personal to them. They want to feel that they're being listened to and taken seriously,” says Martin Stone.

    Firstly, it is important to show that you understand. It is vital that any group or a person making an apology understands the focus—is it sorry for the way it's acted or is it sorry that the complainant feels the way they do? Watch out for the speed of response. The quicker the apology comes, the better it indicates that the person making it has felt an immediate sense of guilt.

    If sincere, the person making the apology will be looking for clues (线索) to see if he or she is being understood, such as eye contact and facial expressions. Performed apologies always have a sense of being “acted out”, and are often accompanied by too many unnatural gestures.

    For a sincere apology, it is also important to avoid promises that can't be kept. Don't say that you'll make sure that this will not happen again if you're not confident that it won't. It could come back to bite you. And do remember that the use of “but” can hugely change the tone (语气) of an apology. As Stone points out, “I'm sorry but…” sounds like you are making excuses and aren't actually taking any form of responsibility.

Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril (鼻孔) slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen (鲸须) whales, such as humpback and Rice whales, have two. 

Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo (立体空间). 

Many types of baleen whales eat tiny animals known as zooplankton (浮游动物), which they catch by filtering (过滤) them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb-the part of the brain that processes smell-is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton (浮游植物). When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales. 

Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits. 

The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies.
