People elect a mayor (市长) to help run a city in the United States. The mayor must keep track of all city activities. 1. They run the city government with the help from city council (市议会).

Mayors may be “weak” or “strong.” In cities that use a weak-mayor system, the city council has most of the power. Under this system, people elect council members and leaders of some departments, or city offices. 2. A city may have many boards and committees, which are groups that make decisions. Each group manages one city department. Although people elect the mayor, he or she has little power. The weak mayor may suggest leaders for city departments. However, the council must approve these suggestions.

In a strong-mayor system, the elected mayor chooses the leaders of each department. 3.　 The elected city council doesn’t have the power to approve the leaders that the mayor chooses. Strong mayors check the work of many different city departments. These departments plan the way that the city will grow and develop.

A strong mayor prepares the city budget. 4. Citizens know whom to blame if services fail. However, the mayor works with the council to figure out the needs of the city and to complete city projects.

Strong mayors have a great deal of control over the government of a city. 5. Most cities have written city charter (章程) that explains the duties of the mayor and other officials.

A. However, mayors do not work alone.

B. However, they must stay within the law.

C. The council never prepares the city budget.

D. The council also may choose leaders for city departments.

E. The mayor makes sure that people who break the laws are punished.

F. In this sense, the mayor decides how to spend money for city services.

G. He or she makes sure that these leaders run their departments efficiently.

Lawmakers in the United States have expanded an investigation into the use of location-tracking systems on mobile devices． The action follows recent reports about the storing of information on the Apple iPhone． Some people consider location tracking to be a threat to personal privacy and security．

Allan Friedman, the research director, says, “All wireless companies do some location tracking as part of their networks． This information is usually stored by the companies, not the devices, and there are laws to protect it． Law enforcement（执法） agencies, for example, have to have a fairly high standard before it can access that data． And the phone company is also prohibited from selling that information．

Now, two researchers report that location tracking information is being stored directly on Apple devices． They said Apple’s newest operating systems gather global positioning system and timestamp information． The information is stored on the device in a file that is also uploaded （上传） to any computer that the device is connected to． The researchers say the information is available to anyone who has access to the device or computer．

Allan Friedman says, “This raises additional concerns． There’s the idea that because it’s on my phone and on my computer, rogue applications（恶意程序） that I pay for or that I’m tricked into downloading may be able to access this data and somehow misuse it．”

Apple says it is “not tracking the location of your iPhone”． It is simply keeping a database of Wi-Fi hotspots and cellphone towers near the user’s location． This information is meant to help the iPhone quickly find its location when needed．

Letters have been sent to some of the leading mobile device developers, including Apple and Google． The letters asked for more information about their location tracking systems． Allan Friedman calls this an important start to strengthening privacy laws． He says, “There aren’t strong controls over things like location information, what they are doing with it, how long they are keeping it． And perhaps the most important question is, is my location data with other facts about me?”

1.Why did American lawmakers investigate the use of location-tracking systems on cell-phones?

A.Because the systems can store users’ information

B.Because many users have suffered loss after using them．

C.Because it is thought to threaten users’ privacy．

D.Because many reporters have shown the problem of the systems．

2. Allan Friedman believes that ________．

A.wireless companies focus on personal privacy．

B.people are forbidden to get access to private data at will

C.phone companies may sell private information secretly

D.customers may ask wireless companies to locate their tracking

3. What do we know from Paragraph 3?

A．  Location tracking information is stored online．

B.Apple’s newest operating systems collect all kinds of information．

C.Location tracking information may be uploaded to any iPhone．

D.Apple’s newest operating systems may reveal the private information of users．

4.Which of the following statements is TRUE according to the passage?

A.Apple denies that it tracks the location of users．

B.The researchers may misunderstand the Apple’s systems．

C.The global positioning system is to blame for rogue applications．

D.The iPhone can quickly find its location by using its user’s information．

Sticky Note Flags

4., whether you’re putting together a big research project or you’re simply reading a book. Whenever you need to remember to take a certain object or assignment to school, place a sticky flag on the door knob, bathroom mirror, or the cereal box the night before. It works like an alarm!

Bedside Notepad

You can keep a notepad beside your bed to write down any items or tasks you have to remember for the next day. As you settle in for the night, take a few moments to think about the things you need to do tomorrow. Then write them down and tear off the sheet in the morning. 5.!
