Tens of thousands of smartphone applications are running ads from the overwhelming(势不可挡的) advertising networks that change smartphone settings and copy people’s contact information without permission.

Aggressive ad networks can disguise(假扮) ads as text message notifications (通告), and sometimes change browser settings and bookmarks. Often, the ads will upload your contacts list to the ad network’s servers--- information that the ad network can then sell to marketers.

Sounds scary? It’s not a giant problem yet, but it’s a growing one. As many as 5% of free mobile apps use an “aggressive” ad network to make money, according to Lookout, a San Francisco-based mobile security company. PhoneLiving was one of the most popular app developers to use these kinds of ad networks; their dozens of talking animal apps have been downloaded several million times. Later, PhoneLiving says it has mended its ways. The company admittedusing invasive techniques to make money from its apps, but said it dropped those methods at the start of July because of bad reviews and declining downloads.

The most popular type of apps that use aggressive ad networks are “Personalisation” apps, which include wallpapers. Comic and entertainment apps are also among the most likely to have rogue(凶猛的) ad networks running behind the scenes. Like aggressive pop-ups on PCs, the bad software isn’t easy to get rid of. Though the damage can typically be removed by deleting the app, it can be hard to tell which app is causing the problems.

When developers create free mobile apps, they usually make money through ads displayed within the app. App makers don’t usually tell people which ad network they are using, which makes it hard to avoid the known offenders. The best defense is to read reviews and avoid downloading apps that have attracted many complaints.

1.What is an example of bad behavior by the annoying mobile ads?

A.They change browser settings and bookmarks.

B.They change people’s calendar settings.

C.They send scam text messages occasionally.

D.They download free versions of games.

2.What do we know about PhoneLiving?

A.Its operation model is against the will of netizens.

B.It was forced to admit its bad behavior.

C.It has changed its business model rapidly.

D.Its relationship with Lookout may break up.

3.Why is the bad software hard to get rid of?

A.The software runs behind the scenes.

B.The app is very hard to delete.

C.It is difficult to find the problem app.

D.The network antivirus is out of date.

4.What does the underlined word, “ invasive”, mean in the third paragraph?

A.innovative         B.positive           C.flexible           D.aggressive

5.What is the main idea of the passage?

A.Mobile ads can attack your phone and steal your contacts.

B.Mobile ads have become popular in recent years.

C.Smartphones have been damaged by mobile ads.

D.You may download some aggressive apps unconsciously.

The concept of health holds different meanings for different people and groups. These meanings have also changed over time. This change is no more evident than in Western society today, when notions of health and health promotion are being challenged and expanded in new ways.

For much of recent Western history, health has been viewed in the physical sense only. That is, good health has been connected to the smooth mechanical operation of the body, while ill health has been attributed to a breakdown in this machine. Health in this sense has been defined as the absence of disease or illness and is seen in medical terms.

In the late 1940s the World Health Organization challenged this physically and medically oriented (导向的) view of health. They stated that health is a complete state of physical, mental and social well-being and is not merely the absence of disease (WHO, 1946). Health and the person were seen more holistically (mind / body / spirit) and not just in physical terms.

The 1970s was a time of focusing on the prevention of disease and illness by emphasizing the importance of the lifestyle and behaviour of the individual. Specific behaviours which were seen to increase risk of disease, such as smoking, lack of fitness and unhealthy eating habits, were targeted. Creating health meant providing not only medical health care, but also health promotion programs and policies which would help people maintain healthy behaviours and lifestyles. While this individualistic healthy lifestyle approach to health worked for some (the wealthy members of society), it was of little benefit to people experiencing poverty, unemployment, underemployment or who had little control over the conditions of their daily life.

During the 1980s and 1990s there has been a growing swing away from seeing lifestyle risks as the root cause of poor health. While lifestyle factors still remain important, health is being viewed also in terms of the social, economic and environmental contexts in which people live. This broad approach to health is called the socio-ecological view of health.

At the Ottawa Conference in 1986, a charter was developed which outlined new directions for health promotion based on the socio-ecological view of health. This charter, known as the Ottawa Charter for Health Promotion, remains as the backbone of health action today. In exploring the scope of health promotion it states that:

Good health is a major resource for social, economic and personal development and an important dimension (尺度) of the quality of life. Political, economic, social, cultural, environmental, behavioural and biological factors can all favour health or be harmful to it. (WHO, 1986)

A.good health means not having any illness

B.health has different meanings for different people in different periods

C.health has always been viewed in terms of the social, economic and environmental contexts in which people live

A.were strong enough

C.had enough money

D.had a good lifestyle

3.        of society benefited most from the healthy lifestyle approach to health. 

A.Rich people

B.Poor people

C.Old people

D.Young people

4.The socio-ecological view of health includes the following broad areas EXCEPT ________.

A.the social contexts

B.the environmental contexts

C.the economic contexts

D.the area of personal development

5.This passage mainly tells us that                 .
