【題目】Security—for the information on your smart phone, as well as for the phone itself—is a hot topic these days.The truth is that you're packing a lot of sensitive information on your phone, and you should keep it safe.

When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map.You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data.

Android does not have an exact equivalent(等價(jià)物), but there are plenty of alternatives. A free app called Lookout offers the findmyphone feature.The paid version allows you to wipe the data from your phone remotely.

Then there is your coffee shop's WiFi network.Anyone with minimal technical expert skill can snoop on(窺視) people using shared wireless networks, harvesting passwords and other personal data. Lookout will caution you when you've logged on to an insecure network, but cannot protect you once you're there.

In order to protect yourself on such networks, you can use a virtual private network, or VPN. This turns all your activity into nonsense to anyone trying to read along with you from across Starbucks. It also keeps websites from tracking you and, if you're travelling, allows you to get access to sites that may be blocked in other countries.

If you have an iPhone, the simplest VPN app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing (瀏覽), as opposed to other VPN apps that require you to start them up manually(手動(dòng)地)．This matters, because even if you decide you want a VPN app, you want to spend approximately zero time thinking about it. For the most part, that was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning. I found myself having to turn the app on and off sometimes, which involved setting my phone constantly.

If even reading about the settings on your phone drive you crazy, then it is probably best to stay away from a VPN app. But if you're the type who can't resist checking your bank balance from your corner bar, the hassle(麻煩) may be preferable to the risk.

【1】Which of the following can warn you against the insecure network?

A. Android. B. VPN.

C. Lookout. D. Find My iPhone.

【2】By using VPN, users can ________．

A. find their lost phones on the Internet

B. remove all the data from the phone remotely

C. check the bank balance now and then

D. save their browsing from being tracked

【3】The underlined word “that” in Para.6 refers to the fact that ________.

A. a VPN app kicks in automatically

B. the users start VPN apps manually

C. the app takes a while to connect

D. users spend no time thinking about it

【答案】

【1】C

【2】D

【3】A

【解析】

試題分析：本文介紹的是智能手機(jī)上的信息安全問(wèn)題。

【1】C細(xì)節(jié)理解題。根據(jù)第四段中Lookout will caution you when you've logged on to an insecure network, but cannot protect you once you're there.可知，當(dāng)你登錄到一個(gè)不安全的網(wǎng)絡(luò)，Lookout不能保護(hù)你，但會(huì)警告你。故選C。

【2】D細(xì)節(jié)理解題。根據(jù)第六段中If you have an iPhone, the simplest VPN app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing (瀏覽), as opposed to other VPN apps that require you to start them up manually(手動(dòng)地)．This matters, because even if you decide you want a VPN app, you want to spend approximately zero time thinking about it.可知，如果你有一個(gè)iPhone，最簡(jiǎn)單的VPN應(yīng)用程序可能是熱點(diǎn)盾，其特點(diǎn)是，當(dāng)你瀏覽網(wǎng)頁(yè)的時(shí)候它會(huì)自動(dòng)啟動(dòng)，而其他VPN的應(yīng)用程序需要你打開(kāi)手動(dòng)。故選D。

【3】A細(xì)節(jié)理解題。根據(jù)文章的內(nèi)容可知，it是指a VPN app kicks in automatically。故選A。

How to unlock your talent

Search

To find your hidden talent (才能), you’ll have to search for it! We all know people who are great at drawing or good at sports, don’t we? They’re the lucky ones who have a natural talent for what they love doing. 【1】 It’s just that we might have to look a little bit harder, that’s all!

Try

Ask

Find out what excites you! The more enthusiastic (熱情的) you are about a hobby, the more you’ll want to keep doing it. And, you’ve guessed it, the more you keep doing it, the better you’ll get!

A. Get excited

B. Don’t give up

C. It won’t happen overnight.

D. Is your grandma great at making cakes?

Once a man got on a bus for New York. He hid in toilet, because he did not want to pay. But a passenger saw her. She tapped the person in front of her on the shoulder and say, "There's a bum(流浪漢) in the toilet. Tell the bus driver." The message was passing from person to person. But anywhere along the way, it changed. The bus driver was told that there was a bomb in the toilet. He immediate stopped the bus and telephoned the police. When the police came to, they told the passengers to get off the bus or stay far away. Then they closed the highway. This soon caused a 15-miles-long traffic jam. Under the help of a dog, the police searched for two hours. Of course they found no bomb!

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

In the cold and plain living room, Matt is sitting in his chair. His eyes don’t shine anymore. He looks extremely old and weak. Today is his birthday, and he is by himself. The only thing that he has been doing all day is thinking about how sad and lonely his life is. As he was looking at some old pictures, he found one special with him and his friends from college. This picture brought back the days when he had friends and his life was full of happiness. Also, it brought him a sad memory. This memory happened forty years ago, during his last year of college.

Throughout college, Matt had a friend named Mark. Mark was tall and skinny. He wore thick glasses. He was shy, smart and responsible. Also, Mark didn’t have as many friends as Matt had. He considered Matt as his best friend. As good friends, they knew everything about each other, and they hung out. Also, they overcame many problems together. They were really good friends.

On his twenty-fourth birthday their life changed. On the night before his birthday, Mark called Matt, “Hi! Matt,” his voice sounded strange. He continued, “ I have an important project to work on. I’m having some problem with this. Maybe, you could come over and help me with it giving me some new ideas. Could you?” Matt asked, “What time?” Mark kept in silence for a minute, and then he said, “At 8 pm. Is it good for you?” Then Matt answered, “OK! See you later.” At that night, it was Matt’s birthday. So, he didn’t want to spend his birthday helping Mark with his project. Matt went to a club with some other guys.

The next morning, Matt noticed that Mark was acting differently. When he went to talk to Mark, Mark ignored him completely. He left the classroom without saying one word. As Mark was walking away, Matt said in an angry voice, “You are selfish. You are just thinking about yourself. I was having fun on my birthday. Why can’t you understand it?”

【題目】When Dekalb Walcott III was just 8 years old, his father, a Chicago fire chief, let him_____on a call. Dekalb says a lot of kids idolized(崇拜) basketball player Michael Jordan when he was growing up in Chicago in the 1990s. Not him.

“I wanted to be like Dekalb Walcott Jr.,” he says of his father.

So when his dad asked if he wanted to go on that call with him when he was 8, Dekalb was excited. “I'm jumping up and down,” saying, “Mom, can I go? Can I go?”

The experience changed Dekalb's life, he tells his dad on a visit to StoryCorps. “My eyes got big from the moment the alarm went off.” the younger Dekalb says. “This is the life that I want to live someday. ”

Now 27, the younger Dekalb is living that life. He became a firefighter at 21 and went to work alongside his dad at the Chicago Fire Department. Before his father retired, the pair even went out on a call together — father supervising(監(jiān)督) son.

“You know, it's everything for me to watch you grow,”his father says. But he also recalls worrying about one particular fire that his son faced.

“I received a phone call that night. And they said, 'Well, your son was at this fire.' I said, 'OK, which way is this conversation going to go?' ” Dekalb Walcott Jr. recalls.

“And they said, 'But he's OK. And he put it out all by himself. Everybody here was proud of him.'”And the word went around, 'Who was out there managing that fire? Oh, that's Walcott! That's Walcott up there!' So, you know, moments like that, it's heaven on Earth for a dad."

Dekalb Walcott Jr. retired in 2009. The younger Dekalb says he's proud of being a second

-generation firefighter. "You know, it makes me look forward to fatherhood as well, because I'm definitely looking forward to passing that torch down to my son."

【1】The underlined phrase “tag along” in Paragraph 1 is closest in meaning to ______.

A. put out fire B. watch basketball

C. ask his mother’s permission D. follow his father

【2】Dekalb Walcott III determined to become a firefighter at the age of _________

A. 8 B. 21 C. 35 D. 27

【3】What can we learn from the last paragraph?

A. Dekalb Walcott Jr is proud to be a second-generation firefighter.

B. Dekalb Walcott III wants his son to become a firefighter too.

C. Dekalb Walcott Jr wants to pass the torch to Dekalb Walcott III.

D. Dekalb Walcott III is proud that his son has become an excellent firefighter.

【4】Which of the following is the best title of the passage?
