福建省三明市第一中学2016-2017学年高二下学期英语第二次月考试卷

根据短文内容的理解,选择正确答案。

    Nobody likes doing the dishes, but it turns out that doing this daily task might pay off in an unexpected way. According to a new study published in the Journal of Pediatrics, washing dishes by hand instead of using a dishwasher might prevent the development of allergies.

    Researchers in Sweden surveyed the parents of 1,029 children ages 7 and 8. They discovered that children whose families hand-washed the dishes instead of using a machine were less likely to have allergies.

    Earlier research has shown that dishes washed by machine are cleaner than those washed by hand. So why would kids who eat off slightly dirtier plates be better off when we talk about preventing allergies? One explanation is based on a theory known as the "hygiene hypothesis (卫生假说)," which says the reason why kids develop allergies is that their surroundings are actually too clean.

    Your immune (免疫) system keeps you healthy by fighting germs (病菌) like bacteria and viruses. But when you have allergies, it overreacts and tries to fight ordinary things like pollen (花粉) or certain foods.

    Being exposed to germs, particularly early in life, is good training for the immune system, says the lead author of the study, Dr. Bill Hesselmar of Queen Silvia Hospital in Sweden. "You excite the immune system in various ways and it becomes tolerant."

    This study shows that while using the dishwasher might be easier, the old-fashioned method of cleaning up could be better for your health.

A、There is no harm done if kids live in a slightly dirty place. B、There is no need to keep the surroundings clean. C、It's better for kids to use clean plates to keep healthy. D、It's wise to use a dishwasher to prevent allergies.
(3)、What does the underlined word "it" in Paragraph 4 refer to?
A、Pollen. B、The immune system. C、The germ. D、A certain food.
(4)、What's the result when our immune system becomes tolerant?
A、It'll overreact to the foods we eat. B、It'll lead to the development of allergies. C、It'll make germs in our body more active. D、It'll prevent allergies and keep us healthy.

    Lights out, phones on. Many teenagers reach for their smartphones or tablets at bedtime, but it may be a good idea to switch off before you hit the pillow.

    According to a study by researchers at Murdoch and Griffith Universities in Australia, using mobile devices late at night could harm teenagers' sleep and lead to an increased risk of mental health problems.

    The study was carried out on more than 1,000 Australian high school students aged between 13 and 16. It lasted four years as student participants moved from Year 8 to Year 11.

    During the study, students were asked what time of the night they received or sent text messages and phone calls, and how well they slept.

    The results are impressive. When the study started in Year 8, more than 85 percent of the students had a mobile pone and around one-third of these students never used phones after lights out. In contrast, 93 percent of Year 11 students had a mobile phone and only 22 percent of then had no late night mobile use when the study concluded four years later.

    As the levels of mobile phone use increased, there was a growth in poor sleep behavior among the students. Meanwhile, mental health problems also increased. Students in Year 8 who were more likely to use phones at night were found to have higher levels of depression (抑郁) and lower self-esteem (自尊心) one year later.

    Lynette Vernon, lead author of the study, explained that phones affect our sleep patterns because of the unnatural blue light they produce. This light could affect the level of hormones (荷尔蒙) in the body, disrupting (打乱) its balance.

     “The more you sit in bed and watch TV, play with your tablet, and play with your phone at three o'clock in the morning, the more these things affect the slow waves of your sleep pattern and give your poor quality sleep,” Mark Levi, a Sydney-based sleep doctor said.

    Based on the findings, the researchers suggested parents should focus on guiding their children's use of mobile devices.

    According to Vernon, the solution is not simply to ban teenagers from using their devices, but teach them better ways of using them

     “Back when they're aged 7 to 10, you have to be a role model. If you put your phone away at night and it doesn't go into your bedroom, it becomes normalizedin the household and you have a much easier job,” he told The Guardian.

    In America, each of the states likes to promote itself with a slogan (口号). I currently live in Utah, where the slogan is '“Life Elevated”. It's a nod to outdoor entertainment in the hill country, including the ski industry. I previously lived in Colorado, a land with red dm. great mountains and golden plains. The slogan there is ''Colorful Colorado”. Years ago I lived in the “Peach State” of Georgia, and I grew up in New Mexico as a little boy, whose slogan is “Land of Enchantment (魔力)”.

    We never seemed to get away from dust in New Mexico, so I appreciate the story of a newcomer to the Land of Enchantment who learned about dusty wind. She was visiting an antique shop and the owner wiped down every item before showing it. The newcomer said, “Everything gets dusty here pretty quickly, doesn't it?” “That's not dust, honey,” the shop owner replied, “That's ENCIIANTMENT”. That made the problem more acceptable or at least can be live with. An escalator (自动扶梯) broke, so he posted a sign to warn customers. He chose not to use the traditional “Out of Order” or “Do Not Use” warnings. Instead, his sign read, “This Escalator Is Temporarily a Stairway”. He turned a minus into humor and made it a plus.

    And in fact there arc sonic things, like the weather, we can't change. All we can change is our ways that we think and feel about them. I believe one of the best techniques to do this is to find some humor in the situation. Finding something amusing or enjoyable of difficulty, a troublesome problem can be one of the most creative and effective things we can do. Sometimes the only sense you can make of a situation is a sense of humor.

    Have you been told you have penicillin allergy? Did your parents tell you that you had a reaction as an infant or child, so you should never take it again? Has it been so long since you had a reaction to penicillin that you don't remember what happened? If you fit any of these descriptions or are just not sure if you have penicillin allergy, there's good news for you: Chances are, you probably don't have it.

    Between 10 to 20 percent of Americans believe they have a penicillin allergy, but a recent study at Mayo Clinic found that only 10 percent of those people are truly penicillin allergic. In other words, 9 out of 10 people who think they have penicillin allergy are avoiding it for no reason. Even in people with documented allergy to penicillin, only about 20 percent are still allergic 10 years after their initial allergic reaction. It's not necessarily a permanent condition.

    Why is this important? Aren't there many other antibiotics you can use if you have penicillin allergy? Penicillin has been around since 1928. Penicillin and its related medicines include amoxicillin, methicillin and amoxicillin-clavulnate. These medicines are highly effective treatments for many bacterial infections, such as strep throat and ear infections. Of course, there are alternative antibiotics, but these are often much more expensive and carry a higher risk of side effects. Typically, these alternative antibiotics are broad-spectrum, meaning they fight many types of bacteria, both good and bad. That can lead to development of drug-resistant bacteria, or deadly “superbugs”. This increases the risk for all of us in the future of not having an effective antibiotic to treat our infection.

    How do you find out if you have penicillin allergy? Board-certified allergists can test you. First, the allergist will get a history from you about your possible allergy. Typical questions include: How long ago did you have the reaction? What type of reaction occurred, and how soon after you took the penicillin did the reaction appear? The testing is done on the forearm by pricking the skin with a needle. If the results are negative and there is no reaction, penicillin will be injected in the skin. These tests are not painful, and results are available in 15 minutes. A positive reaction may lead to some swelling and itching where the test was placed, which usually goes away within an hour.

    In very rare cases, an allergic reaction occurs. This can include hives, swelling, wheezing and/or difficulty breathing. The allergist is trained to treat this rare condition quickly if it happens. If all skin testing is negative, you may be given an oral dose of penicillin in the office. The oral drug challenge is used to verify that you don't have penicillin allergy. Usually, you'll be observed in the office for 30 minutes to make sure you have no problems.

    If you find out you don't have a penicillin allergy, notify your physicians that it's now safe for you to take penicillin. They can take “penicillin allergy” off your chart for good!

    If you also have a friend like Francia Raisa, you are really lucky. On Thursday, singer and actress Selena Gomez, 25, used Instagram(照片墙,一款社交软件) to explain why she was "laying low" this summer. She posted a photo of herself in a hospital bed with her friend Francia Raisa holding hands. She said she recently received a kidney transplant(肾脏移植) from her best friend because of complications(并发症) from lupus(狼疮), an autoimmune disease, which means it is the result of the immune system attacking normal tissue, including the kidneys, brain, heart and lungs.

    People with lupus may first experience tiredness, joint pain or a little bit of rash(皮疹) on their bodies and can go for a long time before their doctors realize it is more serious. Many people see two or four doctors before the real problem is picked up. According to Dr. Kyriakos Kirou, roughly a third to one­half of people with lupus develop kidney disease, and up to one in five of them will eventually need a transplant, sometimes because they weren't treated with effective drugs to prevent the immune system from attacking the kidneys. Though Gomez said that she was "very well now," she warned about the dangers of not taking medical diagnoses(医学诊断) seriously, like she did before.

    Her Instagram post also called attention to two major health topics: the need for living organ donators and the fact that Gomez represents three groups more likely to be diagnosed with lupus and lupus­related kidney disease. Nine out of 10 people diagnosed with lupus are women, and most develop the disease between the ages of 15 to 44. And lupus is two to three times more common among women of color, including Hispanic (西班牙裔)women, according to the Lupus Foundation.

    Raisa is Latin(拉丁人), and Gomez's father is of Mexican origin. While it's not essential that the organ donator and receiver be of the same race, people who share a similar racial background sometimes are better matched, according to data from the United Network for Organ Sharing.
