高三英语单项填空简单题查看答案及解析

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 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 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 that these risks are relatively 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 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 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          C. describe              D. entertain

Eating red meat is linked to cancer and heart disease, but are the risks big enough to justify giving up juicy burgers and delicious steaks? Probably not, according to researchers who reviewed data from 12 clinical trials involving about 54,000 people. In a series of controversial papers, the researchers argue that the increased health risks tied to red meat are small and uncertain, and that cutting back likely wouldn't be worth it for people who enjoy meat.

Those conclusions go against established medical advice. They were swiftly attacked by a group of famous U.S. scientists who took the unusual step of trying to stop the papers from being published until their criticisms were addressed.

The new work does not say red or processed meats like hot dogs and bacon are healthy, or that people should eat more of them. The team’s reviews of past studies generally support the ties to cancer, heart disease and other bad health outcomes. But the authors say the evidence is weak, and that there’s not much certainty meat is really the cause, since other diet and lifestyle factors could be at play.

If the latest example of how divisive nutrition research has become, with its uncertainties leaving the door open for conflicting advice. Critics say findings often aren't backed by strong evidence. Defenders counter that nutrition studies can rarely be conclusive because of the difficulty of measuring the effects of any single food, but that methods have improved.

Based on their analyses, the researchers said people do not have to cut back for health reasons. But they noted that their own advice is weak, and acknowledged that they didn't consider factors such as animal welfare and the environment. Indeed, the case that meat production is bad for animal welfare and the environment is stronger than the case that it's bad for human health, according to an editorial that accompanies the report.

Not all of the report authors agreed with its conclusions. Three of the 14 researchers said they support reducing red and processed meats. A coauthor of one of the reviews is also among those who called for a publication delay.

Those who pushed to postpone publication also questioned why certain studies were included in the reviews while others were left out.

As for his own diet, Dr. Gordon Guyatt, a member of the international research team that conducted the reviews, said he no longer thinks red or processed meats have significant health risks. But he said he still avoids them out of habit, and for animal welfare and environmental reasons.

1.What is the author’s purpose in writing the passage?

A.To introduce a new relationship between health and eating red meat.

B.To urge more people to keep away from eating red meat regularly.

C.To present a new controversial view on impacts of eating red meat.

D.To criticize nutrition studies for lacking of conclusive evidence.

2.What is the author’s attitude towards the new research?

A.Doubtful. B.Positive.

C.Disapproving. D.Objective.

3.Guyatt’s avoiding red meats has the weakest connection with ________.

A.health risks B.diet habits

C.animal welfare D.environmental protection

4.What can we learn from the recent research?

A.Red meats don’t have significant health risks.

B.Reducing meat consumption will be worth it.

C.The report authors have reached a consensus.

D.Consuming red meat will do good to health.

Experts note that an unhealthy lifestyle can put you at great risk of heart disease and stroke. So doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. But there is something else you can do. And it is free and easy. Smile!

Dr. Chockalingam, a heart disease specialist in Columbia, advises his patients to smile. He says a smile may be one way to help your heart. “When we smile, the brain wiring changes. The chemicals that are released are more positive.” He says smiling is the first step in fighting physical and emotional stress and its sometimes harmful effects on human health. This is not just New Age advice. Several studies support his opinion.

When you feel stressed or under pressure, your body releases many natural hormones (荷尔蒙) including adrenaline and cortisol. Adrenaline increases your heart rate and blood pressure. Cortisol is the body’s main stress hormone. It increases sugar in the bloodstream. If you are truly in danger, these hormones can help you. They are part of what we call our fight-or-flight response.

However, when we are stressed for a long period, these stress hormones are ever-present in our bodies. And that, medical researchers warn, may lead to health problems.

Researchers say the connection between stress and heart disease is still unclear. However, they claim that when people are stressed for long periods of time, they may have an unhealthy lifestyle, which can lead to health problems.

Dr. Chockalingam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish ... smiling for seemingly no reason. But a smile does not involve drugs. It is not invasive like a surgical operation. It is free and it has no bad side effects.

“Once people smile, they are relaxing. This relaxation directly lowers blood pressure, improves sugar levels in the blood. If we are smiling, we are breaking that link between stress and health.” And it just may provide a little extra protection to everyone’s heart health.

1.Which of the following agrees with Dr. Chockalingam’s opinion?

A.Smile has the same effects as laughter.

B.Smile can be used to take the place of medicine.

C.Smile is better than any healthy lifestyle to health.

D.Smile can make our body produce beneficial chemicals.

2.What can we know about the mentioned stress hormones?

A.They can lower our blood pressure.

B.They will surely lead to heart diseases.

C.They can benefit us when we are in danger.

D.They will make us live an unhealthy lifestyle.

3.Why does Dr. Chockalingam think smiling is helpful to our health?

A.It can make us relax. B.It increases sugar levels.

C.It has little bad side effects. D.It can happen for no reason.

4.What can be the best title for the text?

A.A Thorough Analysis of the Causes of Heart Diseases

B.One Thing You Can Do Right Now to Help Your Heart

C.One Thing That Is Closely Connected with Stress Hormones

D.The Clear Connection Between Unhealthy Lifestyles and Heart Diseases

When we hear of dangerous diseases, cancer and heart disease are often what first comes to mind． Recently, a virus (病毒) called Ebola has reappeared in Guinea (a country in West Africa), killing 62 people so far． It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc, Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa.
　　 Ebola is named after the Ebola River, where it was first discovered in 1976．There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Restoon, Bundibugyo, and Zaire．The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea.
　　 Ebola is naturally found in fruit bats (果蝠), which pass on the virus to other animals by biting or sucking on (吮吸) their blood．Humans who are suffering from the Ebola infection might have touched the bodily fluids (液体) of the infected animals．Once infected, a human becomes a carrier of the deadly virus.
　　 Since we live in an interconnected world, where the situation in one country can affect us all, the influences of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries．Already the Guinea virus is spreading fast with a few cases spotted in Conakry — the capital of Guinea, far away from the origin of the virus．It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too.
　　 Unfortunately, there are no disease-specific treatments for Ebola．Healthcare workers only supply the infected people with water to keep them in good condition．Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the affected．The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

2.What can we learn about Ebola?
A． It is a newly discovered virus.
B． It is the most dangerous virus in the world.

D． It could cause immediate death for anyone infected.
3.What is mainly described in Paragraph 3?
A． What the Ebola virus is.
B． The influences of Ebola.
C． The treatments for Ebola.
D． How the Ebola virus spreads.
4.Which of the following does the author probably agree with?
