"Through these questions you try to figure out how many in the apartment" Huy said: "I will ask, are you in the apartment number 1, number 2, ..., No. 63. So with most 63 questions you will know which apartment you. You say, "I only need 14 questions, 7 sentences enough to know what floor you are on and 7 you can know exactly what you are in the apartment." Dear children, I have to ask several times to know. How are you Lan in the apartment?

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.

And a new government survey of how young adults spend their leisure time says that 87 percent of people in the UK between the ages of 13 to 19 use the Internet every day. But it’s still important for young people to go out with friends. And the most popular evening out is going to the cinema: 42 percent say it’s their favourite
way to spend an evening.
For people who don’t go out, not surprisingly, television is more popular than radio. 82 percent say that they watch television for more than ten hours a week – mainly for films and news programmes – but only 23 percent listen to the radio. Music is always a favourite topic, but it seems that many people listen to music than can play a music instrument. The survey reveals that 38 percent watch live music, but 30 percent of people between 13 and 19 can play a musical instrument.
Only 32 percent of young adults play sports; with football, swimming, and cycling the most popular activities. But that means that more than two-thirds don’t play any sport!

đồng hồ có ngăn nhỏ để lắp pin, có nắp đậy rất tiện lợi.

 Chiếc đồng hồ này tuy nhỏ nhưng rất tiện dụng. Nó giúp tôi xem thời gian để tổ chức các hoạt động trong ngày. Nó thậm chí còn đánh thức tôi mỗi sáng để đến lớp. Không chỉ vậy, đồng hồ còn là vật trang trí siêu dễ thương cho góc học tập của bé.

Tôi yêu đồng hồ của tôi rất nhiều. Hàng ngày, tôi siêng năng lau chùi cẩn thận và sử dụng nó một cách nhẹ nhàng. Để chiếc đồng hồ có thể đồng hành cùng bạn lâu dài
