Đề bài:

Ann và Bob có một số lượng lớn đồ ngọt mà họ đồng ý chia sẻ theo các quy tắc sau. Ann sẽ lấy một viên ngọt, sau đó Bob sẽ lấy hai viên kẹo và sau đó thay phiên nhau, mỗi người lấy một viên ngọt hơn những gì người kia vừa lấy. Khi số kẹo còn lại ít hơn số kẹo sẽ lấy ở lượt đó thì người cuối cùng lấy hết số kẹo còn lại. Trước sự ngạc nhiên của họ, khi họ ăn xong, họ đều có số kẹo như nhau

Họ quyết định thực hiện chia lại lần nữa, nhưng lần này, trước tiên, họ chia kẹo thành hai đống bằng nhau và sau đó lặp lại quy trình trên với mỗi đống. Ann đi đầu tiên cả hai lần. Họ vẫn kết thúc với cùng một số lượng kẹo mỗi loại.

Số lượng đồ ngọt tối đa ít hơn 1000 mà họ có thể bắt đầu bằng là bao nhiêu?

Lesson 2. Game together across the bridge. Four people need to cross a bridge. Because of the weak demand, each time we go not more than two people, and because it is dark, we have to take the light. Four people walk differently, crossing the bridge with corresponding time of 10 minutes, 5 minutes, 2 minutes and 1 minute. Since there is only one lamp, each passage must be carried back to the next person. When two people go together, cross the bridge with a slower time. The following example is a way to go: - 10 minutes to go with people 5 minutes to bridge, 10 minutes to take. - 5 minutes to take the lamp back, take 5 minutes. - 5 minutes to go with people 2 minutes through the bridge, It takes 5 minutes. - 2 minutes to take the lamp back, take 2 minutes. - 2 minutes with people 1 minute over the bridge, take 2 minutes. Total time is 10 + 5 + 5 + 2 + 2 = 24 minutes. Let's try to get away with a little less time as possible, and if less than 19 minutes is great

Sson 1. Lan trong số căn hộ? Lan nhà ở trong một ngôi nhà 8 tầng, mỗi tầng có 8 căn hộ. Một ngày kia, lớp học hỏi Lan: "Ngôi nhà của bạn trong căn hộ là gì?" "Hỏi tôi một số câu hỏi, tôi sẽ trả lời tất cả các câu hỏi của bạn, nhưng chỉ nói" có "hoặc" không. Huy nói: "Tôi sẽ hỏi bạn ở trong căn hộ số 1, số 2, ..., số 63. Vậy với 63 câu hỏi bạn sẽ biết "Tôi chỉ cần 14 câu hỏi, 7 câu đủ để biết bạn đang ở tầng nào và 7 bạn có thể biết chính xác bạn đang ở trong căn hộ." Các bạn thân mến, tôi phải hỏi nhiều lần để biết. Bạn Lan như thế nào trong căn hộ?

Bài học 2. Trò chơi với nhau qua cây cầu. Bốn người cần băng qua cầu. Bởi vì nhu cầu yếu, mỗi lần chúng ta đi không quá hai người, và bởi vì trời tối, chúng ta phải lấy ánh sáng. Bốn người đi bộ khác nhau, vượt cầu với thời gian tương ứng là 10 phút, 5 phút, 2 phút và 1 phút. Vì chỉ có một đèn, mỗi đoạn văn phải được mang về cho người kế tiếp. Khi hai người đi cùng nhau, băng qua cầu với thời gian chậm hơn. Ví dụ sau đây là một cách để đi: - 10 phút để đi với người dân 5 phút để cầu, 10 phút để đi. - 5 phút để lấy đèn trở lại, mất 5 phút. - 5 phút để đi với người 2 phút qua cây cầu, mất 5 phút. - 2 phút để lấy đèn trở lại, mất 2 phút. - 2 phút với người 1 phút qua cây cầu, mất 2 phút. Tổng thời gian là 10 + 5 + 5 + 2 + 2 = 24 phút. Hãy cố gắng để có được đi với một ít thời gian càng tốt, và nếu ít hơn 19 phút là tuyệt vời

Bài học 3. Cashmere. Mallard mua 27 quả táo giống hệt nhau về kích cỡ và khối lượng. Tuy nhiên, nhân viên bán hàng nói rằng của táo bên phải là một trọng lượng nhẹ hơn. Bạn sử dụng một bảng vảy trên cả hai mặt để tìm táo mà ánh sáng. Số lượng yêu cầu tối thiểu. Hãy giúp bạn tìm thấy quả táo nhỏ. Nếu họ tìm thấy trái cây sau khi ít hơn 5 trọng số, thì nó là tốt.

   In 1988, for the first time in British history, a National Curriculum was introduced. The National Curriculum tells pupils which subjects they have to study, what they must learn and when they have to take assessment tests. [assessment: đánh giá]

   Between the ages of 14 and 16, pupils study for their GCSE (General Certificate of Secondary Education) exams. Pupils must take English Language, Maths and Science for GCSE, as well as a half GCSE in a foreign language and Technology. In addition, they must also be taught Physical Education, Religious Education and Sex Education, although they do not take exams in these subjects.

   At the age of 16, pupils can leave school. If pupils stay on, they usually take A (Advanced) levels, AS (Advanced Supplementary) level or GNVQs (Greater National Vocational Qualifications). It is quite common to combine, for example, two A levels with one AS level, or one A level with one GNVQ.

   Pupils taking A levels study traditional subjects, such as French, Physics or History. To go to university, pupils usually need two or three A levels.

   AS levels are the same standard as A levels, but only half of the content: AS level German pupils take the A-level German language exam, but do not take the A-level German Literature exam.

   GNVQs are vocational qualifications. Pupils usually take on GNVQ in subjects such as Business, Leisure and Tourism, Manufacturing, and Art and Design. One GVNQ (at advanced level) is equal to two A levels.

4. Which of the following subjects do pupils NOT take on GNVQ in?

A. German Literature

B. Business

C. Art and Design

D. Manufacturing

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.

         Students working for their first degree at university are called undergraduates. Then they take their degree we say they graduate, and then they are called graduates. If they continue studying at university after they have graduated, they are called post-graduates. Full-time university students spend all their free time studying. They have no other employment. Their course usually lasts for three or four years. Medical students have to follow a course lasting for six or seven years. Then they graduate as doctors. In Britain, full-time university students have three terms of about ten weeks in each year. During these terms they go to lectures or they study by themselves. Many students become members of academic societies and sports clubs and take part in their activities. Between the university terms they have vacations (or holiday periods). Their vacations are long, but of course they can use them to study at home.

According to the passage, the full-time university students have ________ of about 10 weeks in each year.
