In Britain, greetings cards are sold in chain stores and supermarkets, in newsagents’ shops, corner shops and, increasingly, in shops that specialize in the sale of cards and paper for wrapping presents in.
The most common cards are birthday and Christmas cards. Many Christmas cards are sold in aid of charity and special ‘charity card shops’ are often set up in temporary premises in the weeks before Christmas. A wide variety of birthday cards is available to cater for different ages and tastes. Some, especially ones for young children or for people celebrating a particular birthday, have the person’s age on the front. Many have comic, often risqué, messages printed on them, and cartoon-style illustrations. Others are more sober, with reproductions of famous paintings or attractive original designs. The usual greeting on a birthday card is ‘Happy Birthday’, ‘Many Happy Returns’ or ‘Best Wishes for a Happy Birthday’.
Some people also send special cards for Easter and New Year. Easter cards either portray images of spring, such as chicks, eggs, lambs, spring flowers, etc, or have a religious theme. Cards are produced for every ‘milestone’ in a person’s life. There are special cards for an engagement, a marriage, a new home, a birth, success in an examination, retirement, a death in the family, etc. Some are ‘good luck’ or ‘congratulations’ cards. Others, for example ‘get well’ cards for people who are ill, express sympathy.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the
correct answer to each of the questions from 39 to 48.
               Legend has it that sometime toward the end of the Civil War (1861-1865) a government train carrying oxen traveling through the northern plains of eastern Wyoming was caught in a snowstorm and had to be abandoned. The driver returned the next spring to see what had become of his cargo. Instead of the skeletons he had expected to find, he saw his oxen, living, fat, and healthy. How had they survived?
The answer lay in a resource that unknowing Americans lands trampled underfoot in their haste to cross the “Great American Desert” to reach lands that sometimes proved barren. In the eastern parts of the United States, the preferred grass for forage was a cultivated plant. It grew well with enough rain, then when cut and stored it would cure and become nourishing hay for winter feed. But in the dry grazing lands of the West that familiar bluejoint grass was often killed by drought. To raise cattle out there seemed risky or even hopeless. Who could imagine a fairy-tale grass that required no rain and somehow made it possible for cattle to feed themselves all winter? But the surprising western wild grasses did just that. They had wonderfully convenient features that made them  superior to the cultivated eastern  grasses. Variously known as buffalo grass, grama grass, or mesquite grass, not only were they immune to drought; but they were actually preserved by the lack of summer and autumn rains. They were not juicy like the cultivated eastern grasses, but had short, hard stems. And they did not need to be cured in a barn, but dried right where they grew on the ground. When they dried in this way, they remained naturally sweet and nourishing through the winter. Cattle left outdoors to fend for themselves thrived on this hay. And the cattle themselves helped plant the fresh grass year after year for they trampled the natural seeds firmly into the soil to be watered by the melting snows of winter and the occasional rains of spring. The dry summer air cured them much as storing in a barn cured the cultivated grasses.

II. Topic: Parents are said to influence their children many different way. What do you think about this?
Cha mẹ ảnh hưởng rất nhiều trẻ em của họ suốt đời. 
Tôi nghĩ rằng mọi người được hình thành(đúc) bởi hai yếu tố, gia đình và xã hội mà họ đang sống. .....................
Từ khi sinh ra, con người bị ảnh hưởng bởi những người xung quanh cho đặc điểm của họ. 
Các bậc cha mẹ có một vai trò lớn trong việc nuôi con, mà ảnh hưởng đến cuộc sống của chúng trong một thời gian dài. ..
.
Trong thời kỳ thơ ấu ban đầu, em bé đang nhìn các bà mẹ và ông bố để học cách cư xử cơ bản mà được chấp nhận trong xã hội. 
Một số trong những cách cư xử bao gồm việc không chạy xung quanh trong nhà hàng hoặc đánh những đứa trẻ khác..
 Khi lớn lên, họ tìm hiểu thêm từ các bậc cha mẹ về nghi thức xã hội, mà làm cho chúng phù hợp hơn để sống trong xã hội. .
Trẻ em có xu hướng tìm đến cha mẹ của chúng cho các mô hình vai trò cố ý hay vô tình .
Bên cạnh đó, cha mẹ cũng có thể ảnh hưởng đến thói quen học tập của trẻ em. 
Children of doctors, lawyers, investment bankers, and other professionals see their mothers and fathers work a lot of time, reading books, and punching keyboards, even at home. They are showing their children how to study by their own behavior.
However, parents can also be a bad example for their kids. It is difficult for children who have abusive parents to lead a normal childhood and is possible that they may become similar to their abusive parents when they grow up. In this sense, the parents' negative role in shaping the children's personality cannot be emphasized more.
In conclusion, parents are the best teachers for their children. They leave big marks on their children's lives and are therefore more influential teachers than any others they may have in their lives.
