【題目】根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

【1】 To answer that question you need to ask yourself, is your drinking water supply safe?

Your water may contain many impurities(雜質(zhì)) both man made and natural that can range from many different chemicals to all sorts of different bacteria. 【2】 Though these impurities aren't harmful to us, many can cause bathroom fixtures to rust and corrode and stain our laundry.

The government has set minimum standards for safe drinking water. 【3】 No one really knows the long term effects of many of the things that are allowed in our water.

There are two basic kinds of water quality standards. 【4】 Primary standards deal with the actual cleanliness of the water and whether or not it is healthy to drink and Secondary standards deal with the appearance and smell of the water. It might interest you to know that even though the EPA has set these standards, in 1997 the EPA was happy to state that 88% of the towns served by public water systems were reported to have no violations. However, it means that 12% of the water systems in the country did have water standards violations.

【5】 You wouldn't know until someone told you, if they told you. And by then you could have consumed quite a lot of substandard water. The really only safe thing to do today is take charge and do one better than the standard by either buying bottled water on a regular basis, which is expensive, or by getting a water purifier for your home.

A. What if you/span> were in that 12% ?

B. However, these are the minimum standards.

C. Most of these kinds of impurities are not harmful.

D. They are Primary and Secondary standards.

E. Is a water purifier a good choice today for you and your family?

F. Setting drinking water standards is not an easy process and there are sill many unknowns.

G. Whether you get a glass of drinking water or you take a shower, you expect that water to be safe.

【解析】

試題分析: 本文主要介紹了人們飲用水的現(xiàn)狀以及政府對飲用水質(zhì)量的控制情況。

【1】E 下一句提到“為了回答這一問題”，由此可知此句應(yīng)為一個(gè)問句，由于下文提到了水中的雜質(zhì)問題，因此此處應(yīng)為對于你和你的家人而言凈化器是不是一個(gè)好的選擇。

【2】C.因?yàn)橄戮渲姓f到盡管這些雜質(zhì)對人體無害，但卻會(huì)對人們的衣服及洗浴設(shè)備造成傷害，因此此句應(yīng)為這些雜質(zhì)大部分是無害的。

【3】B.本段首句提到政府對安全飲水設(shè)了最低標(biāo)準(zhǔn)，因此此處應(yīng)選B項(xiàng)。

【題目】Doctor are known to be terrible pilots. They don't listen because they already know it all. I was lucky: I became a pilot in 1970, almost ten years before I graduated from medical school. I didn't realize then, but becoming a pilot makes me a better surgeon. I loved flying. As I flew bigger, faster planes, and in worse weather. I learned about crew resource management (機(jī)組資源管理), or CRM, a new idea to make flying safer. It means that crew members should listen and speak up for a good result, regardless of positions.

I first read about CRM in 1980. Not long after that, an attending doctor and I were flying in bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot He was so busy because of the bad turn, he had forgotten to put the landing gear (起落架) down. He was a better pilot - and my boss - so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness and said, "We need to put the landing gear down now!" That was my first real lesson in the power of CRM, and I've used it in the operating room ever since.

CRM requires that the pilot/ surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn't overreact, which might prevent fellow doctors from voicing opinions again. So when I'm in the operating room, I ask for ideas and help from others. Sometimes they're not willing to speak up. But I hope that if I continue to encourage them, someday someone will keep me from ”landing gear up”.

【1】What does the author say about doctors in general?

A. They like flying by themselves.

B. They are unwilling to take advice.

C. They pretend to be good pilots.

D. They are quick learners of CRM.

【2】The author deepened his understanding of the power of CRM when_______.

A. he saved the plane by speaking up

B. he was in charge of a flying task

C. his boss landed the plane too late

D. his boss operated on a patient

【3】 In the last paragraph”landing gear up” probably means ______.

A. following flying requirements.

B. overreacting to different opinions.

C. listening to what fellow doctors say

D. making a mistake that may cost lives

【4】Which of the following can be the best title for the text?

A.CRM: A New Way to Make Flying Safe

B. Flying Makes Me a Better Doctor

C. The Making of a Good Pilot

D.A Pilot-Tumed Doctor

【題目】Scientists are learning new things about Antarctica, the coldest place on Earth. For example, the Antarctic ice sheet is shrinking. A new study found that summer ice loss in parts of Antarctica was at its highest level in 1,000 years. The study showed that Antarctic ice was melting mostly from below ice shelves, where the water is warmer than the ice.

Eric Rignot is an earth system expert at the University of California, Irvine. He also works for the American space agency, NASA. There he serves as senior research scientist at NASA’s Jet Propulsion Laboratory, also in California. He says ice melting from below is responsible for 55 percent of the shelf loss from 2003 to 2008. That is a much higher rate than scientists thought earlier.

Professor Rignot and his team used satellite observations, radar and computer models to measure features above the ice to learn what was going on below.

The measurements show differences from one area to the next around the continent. The major ice shelves are called Ross, Filchner and Ronne. They make up two-thirds of Antarctica’s ice shelves. But they are responsible for only 15 percent of the melting ice.

The professor says even small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf.

Sixty percent of the Earth’s fresh water is held in the huge Antarctic ice sheet. Professor Rignot says the study will help experts predict how the continent reacts to warmer ocean waters and helps to cause rising sea levels around the world. The study was published in the journal Science.

【1】What’s the main idea of the passage?

A. the Antarctic ice sheet is shrinking

B. the coldest place on earth

C. the major Antarctica’s ice shelves

D. the Atlantic Ocean are changing

【2】How did Eric Rignot and his team do the research?

A. He serves as senior research scientist at NASA’s Jet Propulsion Laboratory.

B. They used satellite observations, radar and computer models to know the things happening below the ice.

C. Small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf.

D. They melted 55% of the Antarctica’s ice to prove their theory is right.

【3】Which is true of the following statements?

A. Ice melting from below is responsible for 35 percent of the shelf loss from 2003 to 2008.

B. The major ice shelves are called Ross, Filchner and Ronne, which make up one-third of Antarctica’s ice shelves.

C. Sixty percent of the Earth’s fresh water is contained in the huge Antarctic ice sheet.

D. Summer ice loss in Antarctica was at its highest level in 1,000 years.

【題目】A

Most children have heard their parents at one time or another yell "sit up straight!" or "don't slouch!"

In the past, this was usually heard at the dinner table as children ate dinner. But these days, it is also heard around another activity-video games.

Ten-year old Owaish Batliwala, from Mumbai, India, admits he spends three to four hours each day playing games on his tablet computer. His mother Mehzabin became concerned when her son started saying that his neck hurt.

She said, "My son started having neck problems around June or July. The pain slowly spread to his hand and his back. He plays for hours on the iPad and mobile phone. This is what has caused the problem."

Sadia Vanjara is a physical therapist. She says the number of young children with chronic pain in their necks, arms and shoulders is on the rise. Dr. Vanjara says the pain is not from aging, accidents or disease. It is from poor posture, or body position, while playing video games.

"They are not aging, they haven't had an accident, their age is like, under 10, they are not complaining, the blood reports are fine, their x-rays are fine, their MRI's are fine, then where is the culprit(罪魁禍?zhǔn)?? And that is the very common thing that is happening amongst all children and that is smart phones and the gadgets(小電器)."

This is a problem in many parts of the world. But there are more smartphone users in India than anywhere else in the world, except China. Networking equipment company Cisco estimates that the number of smartphone users in India will increase from 140 million today to 651 million by 2020.

19-year old student Nida Jameel says she feels pain in the finger which holds the weight of her smartphone most of the day.

She says she uses her smartphone 24/7. This means 24 hours a day, seven days a week, or all the time.

"As I use phone 24/7 (all day) like, so probably yeah, it was because of the phone, continuous usage and Snapchat, Whatsapp, more and more you know social media coming, so like phone is the center of everything."

Dr. Vanjara says the best treatments for the pain are daily exercises.

"And start stretching it in all the possible directions that you can."

Correct posture can help prevent pain. Dr. Vanjara teaches children how to hold their gadgets correctly. She tells a patient to hold the gadget in front of the face. She says that bending the head down to look at the device, strains the neck and creates an unhealthy bend to the back.

Sadia Vanjara predicts we will see not only physical but psychological and emotional problems resulting from overuse of gadgets.

Experts advise taking breaks from using a computer or other device often. Stand up. Stretch your legs, back, shoulders and arms. And when your work or school work is done, unplug and exercise.

【1】According to Paragraph 2, when will one hear yells like “sit up straight!”_________?

A. When playing video games B. When sleeping

C. When walking D. When driving

【2】What caused Owaish Batliwala’s neck to hurt___________?

A. Studying too hard

B. The bad body position

C. Playing the iPad and mobile phone for hours

D. His mother’s concern

【3】According to Sadia Vanjara, the pain is from__________?

A. poor posture

B. aging

C. accidents

D. disease

【4】What can we learn from the passage_________?

A. the number of young children with chronic pain in their necks, arms and shoulders is decreasing

B. the culprit is smart phones and the gadgets

C. there are more smartphone users in India than anywhere else in the world

D. the number of smartphone users in India is 651 million
