Mít, Tèo và Tí ngồi nói chuyện với nhau về sinh nhật của mình. Mít nói rằng: - Ngày sinh của tớ không vượt quá 12. Tớ sẽ nói nhỏ ngày sinh cho Tèo và nói nhỏ tháng sinh cho Tí. Sau khi Mít nói nhỏ với từng bạn xong thì Tèo suy nghĩ một lúc rồi nói: - Tí không thể biết được ngày sinh nhật của Mít. Tí cũng suy nghĩ một lúc rồi nói: - Tèo cũng không biết được sinh nhật của Mít đâu. Hai bạn cứ suy nghĩ một lúc rồi lại thay phiên lặp đi lặp lại hai câu trên. Cho tới một lúc Tí nói: - Bây giờ tớ và Tèo có thể biết được sinh nhật của Mít rồi. Hay thật! Đó là câu chuyện dài nhất mà chúng tớ có thể có trước khi tìm ra sinh nhật của Mít. Hỏi sinh nhật Mít là ngày nào?

3 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. Many people now think that teachers give pupils too much homework. They say that it is unnecessary for children to work at home in their free time. Moreover, they argue that most teachers do not properly plan the homework tasks they give to pupils. The result is that pupils have to repeat tasks, which they have already done at school.

Spain and Turkey are two countries, which stopped homework recently. In Denmark, West Germany and several other countries in Europe, teachers cannot set homework at weekends. In Holland, teachers allow pupils to stay at school to do their homework. The children are free to help one another. Similar arrangements also exist in some British schools.

A pupil who can do his homework in a quiet and comfortable room is in a much better position than a pupil who does his homework in a small, noisy room with the television on. Some parents help their children with their homework. Other parents take no interest at all in their children’s homework. It is important, however, that teachers talk to parents about homework. A teacher suggests suitable tasks for parents to do with their children. Parents are often better at teaching their own children. According to many parents, _____. A: children shouldn’t be given marks for homework B: teachers do not set enough homework.
