【题目】Thanks to expensive data fees, you might be tempted to log onto that free public Wi-Fi service while you’re out and about. 1

“Think about the cost of being connected all the time. Nothing is free,” David Lee, a product manager for Norton, told CNBC. “2” The Harvard Business Review agrees: “You’re taking a risk every time you log on to a free network in a coffee shop, hotel lobby, or airport lounge.”

3 According to a survey by the company Symantic, 87 percent of U.S. consumers have used a public internet connection. And it was found that over 70 percent of them checked their personal email through public Wi-Fi, while 11 percent logged onto their online banking account.

No matter how safe the Wi-Fi connection seems to be, using it leaves your computer or smart phone easy to be attacked by hackers and data thieves. You don’t really know who owns and monitors that router, nor who has access to the data that posses through it. Not to mention, hackers have dozens of ways to compromise public Wi-Fi accounts, from creating a network that appears legal to creating pop-ups that trick the user into downloading malware (恶意软件) onto their computers.4

To protect yourself against hackers, experts say your best defense is a virtual private network (VPN), which encrypts (加密) your online activity. You can download your very own VPN through an app for Apple or Android devices, or by using the free encryption service CyberGhost.5 But before you even start browsing, use this website to make a password that keeps you safe from hackers.

A. These are all of the tricks hackers use to hack your Internet security.

B. That can save you a lot of trouble.

C. The biggest threat is that your data and identity could be completely exposed.

D. Don’t let convenience outweigh the consequences, though.

E. Setting up firewalls and antivirus software will also defend your computer against hackers.

F. Unfortunately, most people are unaware of the dangers.

G Hackers usually steal data in this way.

【题目】任务型阅读
Have you ever wondered what an American high school is really like?
A typical American high school has several large buildings and enough space for about 1,500 students.When students first arrive at school, they go straight to their lockers to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather rent than buy them.
American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough.When they turn 16 years of age, most take a free driving class at school for one term. If students earn passing grades in the class and also pass their state driver's exam, they can begin driving themselves to school.
They must take science, math, English and social studies. They can choose art, homemaking, fashion design and other classes. In some schools students are required to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because each teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.
The regular school day usually ends early in the afternoon. After school more than half of the students are involved in after-school activities. These activities include sports-especially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, photograph or student government.
A. Every student is given a locker.
B. Each day, students take six or seven classes.
C. Sometimes their parents drive them to school.
D. Students must pay back if they lost any of them.
E. This is because each teacher has their own classroom.
F. The regular school day usually ends early in the afternoon.
G. This article will describe a typical American high school and its students.
