§Text Passage
1Technology quietly reshapes family life. Video calls keep distant relatives close, robots share the housework, and family structures and roles become more flexible — dual-income parents, single-parent homes and three-generation households each divide tasks their own way. Our values decide whether technology serves family time or replaces it.
2Lifestyles fall into three rough types: a healthy one built on balanced diet, regular exercise and enough sleep; a sedentary one of long screen hours and little movement; and an unhealthy one of smoking, drinking and late nights. Adolescence is the key time to build habits, with family support and example.
3Community health runs on two tracks. Health promotion — health education, exercise campaigns and vaccination programmes — keeps people well; disease prevention — hand hygiene, clean environments and early treatment — cuts the routes infections travel.
4Air quality, mosquitoes and waste appear in the news constantly. Analyse each issue with the frame of problem, impact and solutions: understand the cause and who is affected, then weigh what a household, a school or the government can do. Families carry healthy habits into the community, and the community protects families in return.

3Step by step Steps
- Technology reshaping family lifeTechnology touches every detail of family living: communication keeps distant families close on video calls, smart appliances share the chores, and online shopping and banking change how households buy and pay. Family structures and roles evolve too — dual-income homes use rice-cooker timers and robot vacuums to stretch time, and grandparents learn tablets to reach grandchildren. Worth reflecting on is our sense of the good life: technology should serve family time, not replace it. For example, a family rule of thirty phone-free minutes after dinner for board games balances the two.
- Changing family structures and rolesModern families take many forms — nuclear, extended, single-parent — each with strengths and strains. Dual careers push households to redistribute chores and care, and roles now follow time and ability rather than gender. A duty chart is a practical tool: list shopping, cooking, cleaning, care of the young and old, and finances, assign and review regularly. For example, a Secondary 3 student can take washing-up two evenings a week plus homework checks for a younger brother, so late-working parents come home to a smooth household — responsibility and independence grow together.
- Three lifestyles comparedA healthy lifestyle means balanced diet, at least an hour of physical activity a day, enough sleep and wholesome leisure; a sedentary lifestyle means long seated screen time and little movement, raising the risks of obesity and poor fitness; an unhealthy lifestyle includes smoking, drinking, late nights and reliance on oily, salty, sugary food. Change starts small, with measurable goals instead of slogans. For example, cutting daily screen time from four hours to two and using the time for a half-hour family walk after dinner, then reviewing energy and fitness after a month.
- Health promotion: person to communityHealth promotion helps people take control of their health, from the personal level — washing hands, eating well, exercising — to schools with healthy-eating policies, PE lessons and fruit days, to community campaigns, vaccination programmes and elderly health checks run by the health authorities. Families implement and model these habits. For example, when grandparents take seasonal flu vaccination, the whole household also builds hand-washing and cough-etiquette habits — protecting the elders and sparing the home a round of colds.
- Disease prevention: breaking the chainInfections spread through a chain: source, route and susceptible host — remove any link and the outbreak stops. Control sources by resting and seeking treatment when ill; cut routes with hand hygiene, masks, disinfection and ventilation; protect the susceptible with vaccination and resistance. Gut infections hinge on food and water safety, respiratory infections on droplets and airflow, and mosquito-borne diseases such as dengue on removing stagnant water. For example, in flu season a class opens windows wider, cleans at lunch break, and sends symptomatic classmates home to rest — the chain breaks at the classroom door.
- Analysing environmental health issuesHealth and environmental hygiene issues fill the news: air pollution and respiratory illness, post-rain mosquito surges and dengue, waste charging and disposal, drinking-water safety. Use a three-step frame: describe the problem and its causes; analyse impacts on individuals, families and the community; compare solutions by feasibility and cost, starting with what a household can do. For example, when the mosquito index rises near your estate, the household answer is weekly clearing of vase saucers and air-conditioner trays plus window screens — far more useful than complaint.
- The family's role in the communityThe family is the basic unit of the community. It extends healthy habits to neighbours — bringing cutlery, sorting waste; joins community activities and volunteering, visiting the elderly, supporting food banks; and speaks up rationally through owners' committees and public consultations. Children who take part grow citizenship at home. For example, the family signs up for the estate clean-up and clothes-collection day, and the Secondary 3 student runs registration and sorting — serving the community while putting classroom knowledge to surprisingly practical use.
5Worked example Example
Flu season is coming. Your class teacher asks your group to design hygiene and infection-control measures for the classroom and a plan to roll them out.
- Identify risks: door handles, shared desks and poor ventilation are the main transmission points — list them first.
- Set measures: daily window ventilation with a cleaning rota, hand-sanitiser supply, and masks plus teacher notification when unwell.
- Assign duties: a rota gives two hygiene monitors each day for airing, cleaning and noting absences.
- Promote: posters and assembly notices on hand-washing and cough etiquette, with the school caretaker supporting disinfection.
- Review: after two weeks check absence numbers and compliance, then adjust.
- Answer: Class infection control mirrors family and community health: use the chain of infection to find risk points, make measures concrete with named duties, explain reasons rather than just rules, and review with data. The flow of problem, measures, responsibility and review transfers straight to household and community hygiene plans — proof that Secondary 3 students can lead change.
