Last week I made the mistake of visiting the village where I grew up. It was a small, friendly community with two farms and a number of old cottages round the village green. I realized very quickly that although in many ways it appears unchanged, in reality hardly anything is the same. All the pretty cottages are there, of course, and both the picturesque farmhouses. But none of the inhabitants are country people. All of them are commuters, who leave early every morning for the nearby town. Neither of the farmhouses is attached to a farm these days; the land has been sold and is managed by somebody in an office somewhere who has little interest in the village itself. There are a few new houses, but they have no local character; you can see the same style anywhere in the country. The whole of the village, in fact, has been tidied up so much that it has become nothing more than just another suburb. 1. When the writer revisited his village, he quickly realized that _____________. A. the village changed a lot in appearance B. everything has almost changed C. all the pretty cottages as well as the farmhouses have been built D. the residents of the village are all commuters 2. Neither of the farmhouses ________________. A. has a connection with a farm B. has been sold C. is attached to the farmers. D. is managed by the commuters 3. The word “managed” in the line 8 can be best replaced by ______________. A. controlled B. spent C. used D. taken 4. According to the writer, __________________. A. the village now has no local character B. all the new houses are the same style C. the village is tidier than it used to D. the village has become nothing but a suburb 5. Which of the following is NOT MENTIONED in the passage? A. The writer has visited the village several times before. B. The writer revisited his village last week. C. In fact, the village has changed much. D. The village nowadays has become another suburb.

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.

   Millions of people are using cellphones today. In many places, it is actually considered unusual not to use one. In many countries, cellphones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

   The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

   On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

   What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

   As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often.

Question: According to the passage, cellphones are very popular with young people because _______.

A. they make them look more stylish

B. they are worrying

C. they are a means of communication

D. they are considered unusual

The sun goes down for a long time. The gentle night falls. Praying in deep, sparkling all the stars. At the far end of the village, the moon is slowly rising from the bamboo forest in the thin mist. The drum frog stirred the air quietly in the countryside. Today is the full moon in August, we are excited to prepare for the Mid-Autumn Festival.

I give you candles to welcome the moon. The yellow grapefruit is tanned, the stem is fresh green placed in the middle, surrounded by bright red roses, ripe. Spicy banana pepper mottled with peanuts. The jade pearl ring wrapped in fresh lotus leaf. The pork pies are nestled together in the new look funny! A sweet scent spread in space is busy laughter baby voices mixed with frogs drumming.

The lanterns dancing in the night like to pull out of the handle to fly to the sky with the moon. The village is filled with silver shimmering along with the voices of young children resound echoing. The lights are finished, we organize the festival. Everyone lit up and lit the lights to look at each other laughing happily. The candy dance in the tray, they also want to play the Mid-Autumn Festival! People sit at the table, excited joy. Never as happy as tonight.

You and your friends in the village all year, grouped together in a row along the snake dragon to take the lights of the Mid-Autumn Festival. The paper lamp star, carp lamp ... with the flickering blaze with moonlight made one. We are bored, we break the bank. In the tray is the part of Sister Hang and Cuong. Sometimes I look up, I feel like they are smiling at us and then hold a candy stick to the part that they give them.

River country as well as the air jubilantly of the full moon night. The sky is clear inside, so why not, sparkling. The full moon shines brightly. Moon as the artist spread the surface of the silver shining silver. Then the river was quiet as a dream of watching the night sky. The river hides the full moon into the bottom of his heart. The naughty wind, constantly shaking the ripples hit the shore.

Watching the sky, plants for a while, suddenly ... I suddenly thought if there is no moon star how? It must have been black, silky, cold and dark, all over the air. There will be no fun scenes, busy lanterns, but just see the strange emptiness. The more I think, the more moon. The great light has only one but two

Mặt trời lặn trong một thời gian dài. Đêm dịu dàng té ngã. Cầu nguyện sâu, lấp lánh tất cả các ngôi sao. Ở cuối làng, mặt trăng đang dần dần mọc lên từ rừng tre trong màn sương mỏng. Con ếch trống khuấy động không khí lặng lẽ ở nông thôn. Hôm nay là trăng tròn vào tháng 8, chúng tôi rất vui mừng chuẩn bị cho Lễ hội Trung thu.

Tôi cung cấp cho bạn nến để chào đón mặt trăng. Quả bưởi màu vàng được rám nắng, thân cây xanh tươi được đặt ở giữa, được bao quanh bởi hoa hồng đỏ tươi, chín muồi. Ớt chuối cay với đậu phộng. Chiếc nhẫn ngọc trai được bọc trong lá sen tươi. Các bánh nướng thịt lợn được nép mình với nhau trong cái nhìn mới buồn cười! Một mùi hương ngọt ngào lan tỏa trong không gian là tiếng cười bận rộn của tiếng trẻ con trộn lẫn với tiếng ếch trống.

Những chiếc đèn lồng nhảy múa trong đêm như kéo ra khỏi tay cầm để bay lên trời với mặt trăng. Ngôi làng tràn ngập ánh bạc lung linh cùng với tiếng nói của những đứa trẻ vang vọng vang dội. Đèn xong, chúng tôi tổ chức lễ hội. Mọi người thắp sáng và thắp đèn để nhìn nhau cười vui vẻ. Nhảy kẹo trong khay, họ cũng muốn chơi Tết Trung thu! Mọi người ngồi ở bàn, vui sướng. Không bao giờ hạnh phúc như tối nay.

Bạn và bạn bè của bạn trong làng cả năm, nhóm lại với nhau trong một hàng dọc theo con rắn rắn để lấy đèn của Lễ hội Trung thu. Ngôi sao đèn giấy, đèn cá chép ... với ngọn lửa nhấp nháy với ánh trăng tạo thành một cái. Chúng tôi đang chán, chúng tôi phá vỡ ngân hàng. Trong khay là một phần của chị Hằng và Cường. Đôi khi tôi nhìn lên, tôi cảm thấy như họ đang mỉm cười với chúng tôi và sau đó giữ một kẹo dính vào phần mà họ cung cấp cho họ.

Sông nước cũng như không khí hân hoan của đêm trăng tròn. Bầu trời trong trẻo, vậy tại sao không, lấp lánh. Trăng tròn tỏa sáng rực rỡ. Mặt trăng khi nghệ sĩ trải rộng bề mặt của bạc sáng bạc. Rồi con sông yên lặng như một giấc mơ ngắm nhìn bầu trời đêm. Con sông che giấu trăng tròn vào tận đáy lòng. Gió nghịch ngợm, liên tục lắc những gợn sóng đánh vào bờ.

Quan sát bầu trời, cây cối trong một lúc, đột nhiên ... Tôi đột nhiên nghĩ nếu không có sao trăng sao? Nó phải có màu đen, mượt, lạnh và tối, khắp nơi trên không trung. Sẽ không có những cảnh vui nhộn, những chiếc đèn lồng bận rộn, nhưng chỉ thấy sự trống rỗng kỳ lạ. Tôi càng nghĩ, mặt trăng càng nhiều. Ánh sáng lớn chỉ có một nhưng hai
