【題目】 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(生物識別) 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.

【答案】

【1】D

【2】A

【3】F

【4】C

【解析】

這是一篇說明文。本文介紹了關(guān)于生物識別技術(shù)一些東西，一些人認(rèn)為更多的使用生物識別全技術(shù)是好的，因為它為我們的生活提供了一道安全屏障，但使用多個安全措施是最好的防御。

【1】根據(jù)下文As technology companies move away from traditional password, biometric security, which includes fingerprint, face and voice ID, is becoming increasingly popular.（隨著科技公司逐漸拋棄傳統(tǒng)密碼，包括指紋、人臉和語音識別在內(nèi)的生物識別安全技術(shù)正變得越來越受歡迎。）可知隨著科技的發(fā)達(dá)，上文所提到的技術(shù)離人們已經(jīng)并不遙遠(yuǎn)了。故D項：Now，this type of technology might not be far away．現(xiàn)在，這種技術(shù)可能并不遙遠(yuǎn)。符合語境。故選D。

【2】根據(jù)后文“Biometrics, ideally, are good,” John Michener, a biometric expert, told tech website Inverse. “In practice, not so much.”（“理想情況下，生物識別技術(shù)是好的，”生物識別專家約翰·麥切納(John Michener)告訴科技網(wǎng)站reverse。“實際上，沒有那么好�！保┛芍硐肭闆r下，生物識別技術(shù)是好的。但是也并沒有人們想象的那么好。故可推測本空是在說明生物技術(shù)存在的問題。故A項：But despite its popularity，experts warn that biometrics might not be as secure as we'd imagined．但專家們警告說，盡管生物識別技術(shù)很受歡迎，但它可能不像我們想象的那么安全。符合語境。故選A。

【3】根據(jù)上文提到了新iPhone的人臉身份識別功能。結(jié)合下文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.（但已經(jīng)有人這么做了。據(jù)Quartz網(wǎng)站報道，11月3日，在社區(qū)網(wǎng)站Reddit上發(fā)布的一段視頻中，兩兄弟展示了他們?nèi)绾斡米约旱哪樈怄i同一款iPhone X。他們甚至不是雙胞胎。）可推知蘋果高級副總裁菲爾·席勒在紹新款iPhone的面部識別功能時，認(rèn)為蘋果手機(jī)不可能被隨便任何人解鎖。而下文推翻了他的說法，but表示轉(zhuǎn)折。故F項：The chance that a random person could look at your iPhone X and unlock it with his face is about one in a million．隨便一個人看到你的iPhone X，然后用他的臉解鎖的幾率大約是百萬分之一。符合語境。故選F。

【4】根據(jù)前文"It's good to see biometrics being used more，"Jain told CBS News，"because it adds another factor for security．（“很高興看到生物識別技術(shù)得到更多的應(yīng)用，”Jain告訴CBS新聞，“因為它增加了另一個安全因素。）中security可對應(yīng)到C項中security measures。表示：但使用多個安全措施是最好的防御。符合語境。故選C。

The friends who introduced me to camping thought that it meant to be a pioneer.【2】We 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.【3】Instead, 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.

【題目】 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(腫瘤) or infections in the brain can cause memory loss. A doctor should treat serious medical conditions like these as soon as possible.

【題目】 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.

California: Wine Guide

It isn’t called “Wine Country” for no reason. Northern California, specifically Napa Valley and Sonoma Valley, produce over 60,000 registered wine labels, making vino (酒類產(chǎn)品) the state’s most valuable agricultural product.

【題目】閱讀下面短文，根據(jù)所給情節(jié)進(jìn)行續(xù)寫，使之構(gòu)成一個完整的故事。

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 (有軌電車) 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. 所續(xù)寫短文的詞數(shù)應(yīng)為150左右；

2. 至少使用5個短文中標(biāo)有下劃線的關(guān)鍵詞語；
