【题目】 Imagine you're standing in line to buy an afterschool snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR code with your smartphone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.

1 As technology companies move away from traditional password, biometric(生物识别) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

In 2013, Apple introduced the iPhone 5s, one of the first smartphones with a fingerprint scanner. Since then, using one’s fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives. And since last year, Samsung has featured eye-scanning technology in its top smartphones, while Apple’s new iPhone X can even scan a user’s face.

2 “Biometrics, ideally, are good,” John Michener, a biometric expert, told tech website Inverse. “In practice, not so much.”

When introducing the new iPhone’s Face ID feature at Apple’s Keynote Event in September, Phil Schiller, Apple’s senior vice president, said, “3

But it’s already been done. In a video posted on community website Reddit on Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face, Quartz reported. And they aren’t even twins.

“We may expect too much from biometrics,” Anil Jain, a computer science professor at Michigan State University, told CBS news. “No security systems are perfect.”

Earlier this year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smartphone for police.

“It’s good to see biometrics being used more,” Jain told CBS News, “because it adds another factor for security. 4

A. But despite its popularity, experts warn that biometrics might not be as secure as we’d imagined.

B. Security experts don’t think it absolutely necessary to use biometric technology.

C. But using multiple security measures is the best defense.

D. Now, this type of technology might not be far away.

E. If a person’s biometric information is stolen, that could have extremely serious consequences for that individual

F. The chance that a random person could look at your iPhone X and unlock it with his face is about one in a million.

【解析】

这是一篇说明文。本文介绍了关于生物识别技术一些东西,一些人认为更多的使用生物识别全技术是好的,因为它为我们的生活提供了一道安全屏障,但使用多个安全措施是最好的防御。

1根据下文As technology companies move away from traditional password, biometric security, which includes fingerprint, face and voice ID, is becoming increasingly popular.(随着科技公司逐渐抛弃传统密码,包括指纹、人脸和语音识别在内的生物识别安全技术正变得越来越受欢迎。)可知随着科技的发达,上文所提到的技术离人们已经并不遥远了。故D项:Nowthis type of technology might not be far away.现在,这种技术可能并不遥远。符合语境。故选D

2根据后文“Biometrics, ideally, are good, John Michener, a biometric expert, told tech website Inverse. In practice, not so much.”(“理想情况下,生物识别技术是好的,”生物识别专家约翰·麦切纳(John Michener)告诉科技网站reverse。“实际上,没有那么好。”)可知理想情况下,生物识别技术是好的。但是也并没有人们想象的那么好。故可推测本空是在说明生物技术存在的问题。故A项:But despite its popularityexperts warn that biometrics might not be as secure as we'd imagined.但专家们警告说,尽管生物识别技术很受欢迎,但它可能不像我们想象的那么安全。符合语境。故选A

3根据上文提到了新iPhone的人脸身份识别功能。结合下文But its already been done. In a video posted on community website Reddit on Nov 3, two brothers showed how they were each able to unlock the same iPhone X using their own face, Quartz reported. And they arent even twins.(但已经有人这么做了。据Quartz网站报道,113日,在社区网站Reddit上发布的一段视频中,两兄弟展示了他们如何用自己的脸解锁同一款iPhone X。他们甚至不是双胞胎。)可推知苹果高级副总裁菲尔·席勒在绍新款iPhone的面部识别功能时,认为苹果手机不可能被随便任何人解锁。而下文推翻了他的说法,but表示转折。故F项:The chance that a random person could look at your iPhone X and unlock it with his face is about one in a million.随便一个人看到你的iPhone X,然后用他的脸解锁的几率大约是百万分之一。符合语境。故选F

4根据前文"It's good to see biometrics being used more"Jain told CBS News"because it adds another factor for security.(“很高兴看到生物识别技术得到更多的应用,”Jain告诉CBS新闻,“因为它增加了另一个安全因素。)中security可对应到C项中security measures。表示:但使用多个安全措施是最好的防御。符合语境。故选C

【题目】If anyone had told me three years ago that I would be spending most of my weekends camping. I would have laughed heartily. Campers, in my eyes, were people who enjoyed insect bites, ill-cooked meals, and uncomfortable sleeping bags. They had nothing in common with me.1

The friends who introduced me to camping thought that it meant to be a pioneer.2We sleep in a tent, cooked over an open fire, and walked a long distance to take the shower and use the bathroom. This brief visit with Mother Nature cost me two days off from work, recovering from a bad case of sunburn and the doctor’s bill for my son’s food poisoning.

I was, nevertheless, talked into going on another fun-filled holiday in the wilderness.3Instead, we had a pop-up camper with comfortable beds and an air conditioner. My nature-loving friends had remembered to bring all the necessities of life.

4 We have done a lot of it since. Recently, we bought a twenty-eight-foot travel trailer complete with a bathroom and a built-in TV set. There is a separate bedroom, a modern kitchen with a refrigerator. The trailer even has matching carpet and curtains.

5 It must be true that sooner or later, everyone finds his or her way back to nature. I recommend that you find your way in style.

A.I must say that I have certainly come to enjoy camping.

B.Things are going to be improved.

C.I was to learn a lot about camping since then, however.

D.The trip they took me on was a rough one.

E.After the trip, my family became quite interested in camping.

F. This time there was no tent.

G. There was no shade as the trees were no more than 3 feet tall.

【题目】 Forgetfulness can be a normal part of aging. 1 As a result, some people may notice that it takes longer to learn new things; they don’t remember information as well as they did, or they lose things like their glasses, cellphones or other small items. These are usually signs of mild forgetfulness, not serious memory problems.

2 For example, medication side effects, vitamin B12 shortage, alcoholism, tumors(肿瘤) or infections in the brain can cause memory loss. A doctor should treat serious medical conditions like these as soon as possible.

Emotional problems, such as stress, anxiety or depression, can make a person more forgetful. For instance, someone who has recently retired or who is coping with the death of a relative or a friend may feel sad, lonely or worried. 3

The confusion and forgetfulness caused by emotions are usually temporary and go away when the feelings fade. The emotional problems can be eased by supportive friends and family. 4 Treatment may include counseling, medication or both.

If you’re concerned that you or someone you know has a serious memory problem, talk with your doctor. 5 Health care professionals can recommend ways to manage the problem or make suggestions on treatment or services that might help you out.

A. Consider participating in clinical trials or studies.

B. It’s advisable to have health issues treated in time.

C. He or she can diagnose the problem or refer you to a specialist.

D. But if they last for a long time, it is necessary to get help from a doctor.

E. Some memory problems are related to health issues that may be treatable.

F. As people get older, changes occur in all parts of the body, including the brain.

G. Trying to deal with these life changes leaves some people confused or forgetful.

【题目】 Alabama: Priester’s Pecans

Dessert in the South basically starts and ends with an ooey-gooey pecan (核桃) pie. Especially in Alabama, where the pecan is the official state nut. While there are plenty of farms that pick and package pecans, perhaps the most famous is Priester’s, a family-run business that’s been supplying Alabama with its favorite nuts for over seven decades.

Alaska: Salmon jerky

Forget beef jerky (肉干) - in Alaska, it’s all about the salmon jerky. Home to five different species of the flavorful fish (king, red, pink, silver, and chum), the northernmost state produces nearly one-third of the wild salmon consumed around the world. Bonus: Salmon is one of the seven healthiest fish you can eat.

Arizona: Saguaro cactus

The largest cactus (仙人掌) in the United States, the saguaro cactus is found only in Arizona’s Sonoran Desert. Living to be up to 200 years old, the cacti, whose flower is also the state’s flower, are generally around 30 feet tall and can grow unlimited arms. Want to see for yourself? Visit one of these 10 outstanding desert escapes in America.

【题目】阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。

A gift of gold

It was the winter of 1937, just after Christmas. The Depression was still going on, but I was in good spirits. I was going to graduate from elementary school, but my mother still dressed me in shorts. Most of my classmates had given up wearing shorts. For the graduation ceremony, all the boys were expected to wear white shirts and dark blue wool pants.

I waited until a week before I told my mother. On a cold Monday afternoon I went home from school.

“Mom,” I said, “about graduation...”

“Yes?” she answered.

“They are going to give me the first-prize medal,” I said.

Still working over the stove, she looked over her shoulder at me and smiled broadly. “That’s wonderful, Babe. Dad and I will be both there, and we’ll be the proudest.”

She must have seen by the look on my face that something was wrong. She turned her back and said, “So?”

“So, I have to get long pants,” I said.

“Babe, we don’t have money for new pants right now,” she said.

“Okay,” I burst out.“Then I won’t go to graduation. Plus, I’m running away from home!”

“If I were you, I wouldn’t pack my bags. We’ll solve the problem of pants somehow,” she said.

The following Saturday, when my mother said “Let’s go shopping”, I knew that she had solved the problem. Then we left home. We took the trolley (有轨电车) and got off at Southern Boulevard, the best shopping street. The clothing store was just a couple of blocks away.

But first we walked a short way down the Boulevard and stopped at a place I had never noticed before.

“Wait here,” she said. Then she entered a storefront that looked like a bank and opened the door with the hand with a gold wedding ring on her ring finger.

She went out about ten minutes later with a purse in her left hand, and then we went to the pants store. I chose a pair of pants. After a patient bargain with the seller, my mother bought it at the price of three dollars and fifty cents and handed it to me.

注意:1. 所续写短文的词数应为150左右;

2. 至少使用5个短文中标有下划线的关键词语;

3. 续写部分分两段,每段的开头语已为你写好;

4. 续写完成后,请用下划线标出你所使用的关键词语。

Paragraph 1:

I was holding the pants tightly under my arm when my mother went to pay the money.
