I.-Choose the item among A, B, C or D that best answers the question about the story. I often hear or read about ‘natural disasters’ – the eruption of Mount St. Helen, a volcano in the state of Washington. Hurricane Andrew in Florida, the floods in the America Midwest, terrible earthquakes all over the world, huge fires, and so on. But I’ll never forget my first personal experience with the strangeness of nature – ‘the London Killer Fog’ of 1952. It began on Thursday, December 4, when a high-pressure system of warm air covered southern England. With the freezing-cold air below, heavy fog formed. Pollution from factories, cars and coal stoves mixed with the fog. The humidity was terribly high, there was no breeze at all. Traffic such as cars, trains, boats stopped. People couldn’t see, and some walked onto the railroad tracks or into the river. It was hard to breathe, and many people got sick. Finally, on Tuesday, December 9, the wind came and the fog went away. But after that, even more people got sick. Many of them died. 1. Which ‘natural disaster’ isn’t mentioned in the passage?

The people of Kiribati are afraid that one day their country in the not-too-distant future will disappear from the surface of the earth. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tide, which swept across the island and destroyed houses, came when there was neither wind nor rain. This never happened before. What is causing these mysterious high tides? The answer may be global warming. When fuels like oil and coal are being burned, pollutants are released, these pollutants hold heat in the earth’s atmosphere. Warmer temperatures cause water to expand and also create more water by melting glaciers and polar ice caps. If the situation continues, scientists say that many countries will suffer, Bangladesh, for example, might lose one-fifth of its land. The coral island nations of the Pacific like Kiribati and the Marshall Islands, however, would face an even worse fate – they would be swallowed by the sea. The loss of these coral islands would be everyone’s loss. Coral formations are home to more species than any other place on the earth. T F 1. In Kiribati there were sudden high tides coming when there was no wind or rain.   2.High tides without wind or rain often happen in Kiribati.   3. Global warming is definitely the cause of those mysterious high tides.   4.The loss of coral islands doesn’t affect people on the earth   5.

It was dark and the wind was howling. I was terrified. The building was falling down all around me. The wind was awful. It reached a speed of 234 miles per hour. I was cut and bleeding from head to toe. Finally, someone found me 8 km from my house and they took me to hospital. 1.

Cảm nhận của em vềquan niệm thời gian và tuổi trẻcủa nhà thơ Xuân Diệu được thểhiện trong đoạn thơ sau. Qua đó, liên hệvới bản thân.Xuân đang tới, nghĩa là xuân đang qua,Xuân còn non, nghĩa là xuân sẽgià,Mà xuân hết, nghĩa là tôi cũng mất.Lòng tôi rộng, nhưng lượng trời cứchật,Không cho dài thời trẻcủa nhân gian,Nói làm chi rằng xuân vẫn tuần hoàn,Nếu đến nữa không phải rằng gặp lại.Còn trời đất, nhưng chẳng còn tôi mãi,Nên bâng khuâng tôi tiếc cảđất trời;Mùi tháng, năm đều rớm vịchia phôi,Khắp sông, núi vẫn than thầm tiễn biệt...Cơn gió xinh thì thào trong lá biếc,Phải chăng hờn vì nỗi phải bay đi?Chim rộn ràng bỗng đứt tiếng reo thi,Phải chăng sợđộphai tàn sắp sửa?Chẳng bao giờ, ôi! Chẳng bao giờnữa...(Trích “Vội Vàng, Xuân Diệu, sgk NgữVăn 11, tập 2, trang 22)

A smart board is an interactive whiteboard. It can be connected to one or more laptops, PCs, tablets, or other electronic devices. Smart boards are extremely useful in a classroom because they can engage students, provide interactive opportunities that a traditional whiteboard, blackboard or flip chart can't, and can also develop students' computer skills along with their English skills. Smart boards also have touch-screen technology so you do not actually need a computer to access the basic functionality. You can write on a smart board with special pens which are usually provided with the board, and anything written on the board can be saved for future reference, or printed out. It is great, for example, if you are doing a brainstorming session or a mind map with your classmates and you want to keep a record of it. If you don't want to draw with the pens, you can use a keyboard and type onto a programme such as Word, and have it appear on the screen for everyone to see. This is great if you are doing an exercise with your class and you want everyone to be able to see the answers during the checking stage. You can also run PowerPoint presentations on an interactive whiteboard. These can sometimes be great for grammar or vocabulary presentations and the advantage of them is that students can make contributions. If you have the Internet access, you can access websites and put them onto a white board. This is great in an English classroom if you have online quizzes or games you want to use. Students can actually come up to the board and select their answers. This involves them directly in the board work, which they usually love. You can also run video clips or sound files from the Internet, or some which are saved on your computer. In short, a smart board can make the lessons more varied, and can give students a more active role in the lesson. 36. A smart board is more useful than a traditional board because .
