The family in Britain is changing. The once typical British family headed by two parents has undergone substantial changes during the twentieth century. In particular there has been a rise in the number of single-person households, which increased from 18 to 29 per cent of all households between 1971 and 2002. By the year 2020, it is estimated that there will be more single people than married people. Fifty years ago this would have been socially unacceptable in Britain.

In the past, people got married and stayed married. Divorce was very difficult, expensive and took a long time. Today, people's views on marriage are changing. Many couples, mostly in their twenties or thirties, live together (cohabit) without getting married. Only about 60% of these couples will eventually get married.

In the past, people married before they had children, but now about 40% of children in Britain are born to unmarried (cohabiting) parents. In 2000, around a quarter of unmarried people between the ages of 16 and 59 were cohabiting in Great Britain. Cohabiting couples are also starting families without first being married. Before 1960 this was very unusual, but in 2001 around 23 per cent of births in the UK were to cohabiting couples.

People are generally getting married at a later age now and many women do not want to have children immediately. They prefer to concentrate on their jobs and put off having a baby until late thirties.

The number of single-parent families is increasing. This is mainly due to more marriages ending in divorce, but some women are also choosing to have children as lone parents without being married.

Read the text and choose the answer (A, B, C or D) which you think fits best according to the text. (10pts) Life originated in the early seas less than a billion years after the Earth was formed. Yet another three billion years were to pass before the first plants and animals appeared on the continents. Life's transition from the sea to the land was perhaps as much of an evolutionary challenge as was the genesis of life.What forms of life were able to make such a drastic change in lifestyle? The traditional view of the first terrestrial organisms is based on mega fossils-relatively large specimens of essentially whole plants and animal. Vascular plants, related to modern seed plants and ferns, left the first comprehensive mega fossil record. Because of this, it has been commonly assumed that the sequence of terrestrialization reflected the evolution of modern terrestrial ecosystems. In this view, primitive vascular plants first colonized the margins of continental waters, followed by animals that fed on the plants, and lastly by animals that preyed on the plant-eater. Moreover,the mega fossils suggest that terrestrial life appeared and diversified explosively near the boundary between the Silurian and the Devonian periods, a little more than 400 million years ago.Recently, however, paleontologists have been taking a closer look at the sediments below this Silurian-Devonian geological boundary. It turns out that some fossils can be extracted from these sediments by putting the rocks in an acid bath. The technique has uncovered new evidence from sediments that were deposited near the shores of the ancient oceans-plant microfossils and microscopic pieces of small animals. In many instances the specimens are less than one-tenth of a millimeter in diameter. Although they were entombed in the rocks for hundreds of millions of years, many of the fossils consist of the organic remains of the organism.These newly discovered fossils have not only revealed the existence of previously unknown organisms, but have also pushed back these dates for the invasion of land by multi-cellular organisms. Our views about the nature of the early plant and animal communities are now being revised. And with those revisions come new speculations about the first terrestrial life-forms.
