One of the most common and most dangerous causes of borne accidents is wrong and careless use of electrical equipment. People will continue to use a loose plug without first turning off the power. In spite of warnings, one will carry an electric heater into the bathroom when he is going to have a bath. Sometimes one forgets to cut off the power before mending a lamp or something else. All these will cause accidents. So the rule about anything that works by electricity is: SWITCH OFF before you touch anything and don't pretend you know when you actually don't.
If you've got children in the house, it's always best to keep medicines of any kind out of their reach. Otherwise they may be taken for candies or a new kind of drink. When there are older people living with you, you have to take particular care in a number of ways in order to make them safe and happy.
Fire, of course, is always a risk. So, remember not to dry clothes in front of fires, or leave stoves in the middle of rooms where they can easily be knocked over. And don't forget to keep the children away from fire. Smoking, too, may cause fire. So you'd better give it up.
Safety first may mean a little more time and care, but it may save a lot of trouble.
(30)
A.Wrong use of electrical equipment, scald and smoking.
B.Electric shock, medicine poisoning and fire.
C.Electric bum and gas poisoning.
D.All of the above.

Following the Irish War of Independence and the subsequent Anglo-Irish Treaty, Ireland gained independence from the United Kingdom in 1922. Initially a dominion, Ireland received official British recognition of full legislative independence in the Statute of Westminster of 1931. A new constitution was adopted in 1937, by which the name of the state became “Ireland.” In 1949, Ireland was declared a republic under the Republic of Ireland act 1948.
Ireland ranks among the wealthiest countries in the world in terms of GDP per capita. In 1973, Ireland enacted a series of liberal economic policies that resulted in rapid economic growth, coupled with a dramatic rise in inequality. The country achieved considerable prosperity from 1995 to 2007. This was halted by an unprecedented financial crisis that began in 2008, in conjunction with the concurrent global economic crash.
In 2011 and 2013 Ireland was ranked as the seventh-most developed country in the world by the United Nations Human Development Index. It also performs well in several metrics of national performance, including freedom of the press, economic freedom and civil liberties. It pursues a policy of neutrality through non-alignment.
The population of Ireland stood at 4,588,252 in 2011, an increase of 8.2 percent since 2006. As of 2011, Ireland had the highest birth rate in the European Union (16 births per 1,000 of population). In 2012, 35.1 percent of births were to unmarried women. Annual population growth rates exceeded 2 percent during the 2002-2006 period, which was attributed to high rates of natural increase and immigration. This rate declined somewhat during the subsequent 2006-2011 period, with an average growth rate of 1.6 percent.
Ireland ranks fifth in the world in terms of gender equality. In 2011, Ireland was ranked the most charitable country in Europe, and second most charitable in the world. Contraception was controlled in Ireland until 1979, however, the receding influence of the Catholic Church has led to an increasingly secularized society . In 1983, the Eighth Amendment recognized “the right to life of the unborn”, subject to qualifications concerning the “equal right to life” of the mother. The passage of the Thirteenth and Fourteenth Amendments guarantees the right to have an abortion performed abroad, and the right to learn about “services” that are illegal in Ireland, but legal abroad. The prohibition on divorce in the 1937 Constitution was repealed in 1995 under the Fifteenth Amendment. Divorce rates in Ireland are very low compared to European Union averages while the marriage rate in Ireland is slightly above the European Union average.
Capital punishment is constitutionally banned in Ireland, while discrimination based on age, gender, sexual orientation, marital or familial status, religion and race is illegal.
Ireland became the first country in the world to introduce an environmental levy for plastic shopping bags in 2002 and a public smoking ban in 2004. Recycling in Ireland is carried out extensively and Ireland has the second highest rate of packaging recycling in the European Union.

Energy is used in three principal places: businesses, homes, and transportation systems. The most important energy source for businesses is coal, followed by natural gas and petroleum. Some businesses use coal directly in an industrial operation, while others rely on electricity, generated primarily at coal-burning power stations.
At home, energy primarily is used to generate heat and hot water. Natural gas is the most common source of home heat and hot water, followed by petroleum. Like businesses, homes also use electricity supplied from coal-burning power plants. Petroleum products operate virtually all transportation systems, including automobiles, trucks, buses, airplanes, and some trains. Only subways, streetcars, and some trains run on coal-generated electricity.
Petroleum, natural gas, and coal are known as fossil fuels. A fossil fuel comes from the residue of plants and animals buried beneath the earth's surface millions of years ago. As the earth's crust moved, these buried plants and animals were subject to intense changes in pressure and temperature.
The global distribution of fossil fuels raises two problems. First, some regions have relatively abundant reserves of one or more fossil fuels, while other regions have little. Second, fossil fuel reserves are not located in the same regions as their consumers.
In general, the relatively developed countries of North America, Europe, and the former Soviet Union possess a disproportionately large share of fossil fuel reserves. They contain approximately one-fourth of the world's population but possess more than half of the world's proven reserves of the three major fossil fuels. By far the largest proven reserves of fossil fuels are located in the former Soviet Union. The former soviet Union possesses more than one-third of the world's proven natural gas reserves and more than one-fourth of the proven coal reserves; it also ranks sixth in the world in proven petroleum reserves. The United States has more than one- fourth of the world's proven coal reserves, but its proven petroleum and natural gas reserves are relatively small.
European countries possess one-sixth of the world' s proven coal reserves, for the most part in Germany and Poland, but less than 5 percent of the petroleum reserves and less than 10 percent of the natural gas reserves. The region's major sources of petroleum and natural gas lie beneath the North Sea. Japan has virtually no proven fossil fuel reserves.
Overall, the developing regions do not have a fair share of energy reserves, but the situation varies by type of fossil fuel. Developing countries possess only one-tenth of the world's proven coal reserves, but nearly one-half of the natural gas and nine-tenths of the petroleum.
Energy reserves are not distributed uniformly within the developing world. A handful of the developing countries are well endowed with one of the fossil fuels, but most countries in Africa, Asia, and Latin America have relatively little. China accounts for most of the proven coal reserves in developing countries. Approximately 60 percent of the world's proven petroleum' reserves are concentrated in the five Middle Eastern states of Saudi Arabia, Kuwait, Iran, Iraq and the United Arab Emirates.
According to the passage, which is the principal energy source of home heat?
A.Wood.
B.Coal.
C.Natural gas.
D.Petrol.
