When people talk about Nha Trang, the biggest city in Khanh Hoa Province, they often think of a tropical paradise. Nha Trang is a famous seaside resort. It has a long coastline with beatiful white sandy beaches.

In the morning and afternoon, tourists can take part in various fascinating outdoor activities such as mud bathing, swimming, snorkeling or scuba diving. Snorkeling and scuba diving are both interesting sports, as swimmers may swim underwater and admire the lives at the bottom of the sea. Besides, tourist can also take boat trips to the islands. One of the most enjoyable trips is the trip to Mieu Island, where Tri Nguyen Aquarium was built in 1999. This aquarium is now home to different kinds of colorful fish and even a few sharks.

In addition, tourists can spend an evening visiting a fishing village, where they could get a taste of the local seafood. There are crabs, shrimps, lobsters, clams, oysters, and several other kind of fish - all are fresh and delicious.

Which of the following sentences is not true?

A. Nha Trang is a nice seaside resort

B. Tri Nguyen Aquarium is on an island

C. Most of tourists are interested in snorkeling and scuba diving

D. The local seafood is fresh and delicious

Many people from rural areas are leaving behind their traditional way of life and moving to the city. They believe that well-paying jobs are plentiful in the city.

At home on the farm, life is always a straggle with nature. Typhoons, floods or droughts can easily destroy a harvest and leave the farmer with little or no money until the following year. Often fanners look for other work when they need more money for their family.

The increase in population, however, has led to overcrowding in many cities. This puts a strain on schools and hospitals, as well as water and electricity supplies. Increased pollution is another unpleasant result.

There is also a human side to this tragedy. Families sometimes have to live apart. In these cases, children may live at home with relatives, while their parents so and live in an urban area.

Governments all over the world are trying to provide facilities for these migrants, but it can be quite a problem.

Nhiều người từ nông thôn đang bỏ lại cuộc sống truyền thống của họ và di chuyển đến thành phố. Họ tin rằng các công việc được trả lương cao đang dồi dào trong thành phố.

Tại nhà trong nông trại, cuộc sống luôn là sự lạc lõng với thiên nhiên. Bão, lũ lụt hoặc hạn hán có thể dễ dàng hủy hoại mùa màng và để lại cho nông dân ít hoặc không có tiền cho đến năm sau. Thường thì những người nông dân tìm kiếm những công việc khác khi họ cần nhiều tiền hơn cho gia đình họ.

Sự gia tăng dân số, tuy nhiên, đã dẫn đến sự quá tải ở nhiều thành phố. Điều này gây căng thẳng cho các trường học và bệnh viện, cũng như cung cấp nước và điện. Tình trạng ô nhiễm gia tăng là một kết quả khó chịu.

Cũng có một khía cạnh của con người đối với bi kịch này. Các gia đình đôi khi phải sống xa nhau. Trong những trường hợp này, trẻ em có thể sống ở nhà với người thân, trong khi cha mẹ chúng và sống ở khu vực thành thị.

Chính phủ các nước trên thế giới đang cố gắng cung cấp cơ sở cho những người di cư, nhưng có thể là một vấn đề.

A hurricane is a huge storm that forms over warm ocean water. Bands of thunderstorms form and swirl around and around because the rotation of the earth. As more and more thunderstorms form, the hurricane gets bigger and bigger. A hurricane is one of the world's worst storms because it can last for days or weeks.

Hurricanes can also be very large. They may cover hundreds of miles and affect large areas of land. For a storm to be classified as a hurricane, wind speeds within the storm have to reach at least 74 per hour. But hurricane winds can reach speeds of over 155 miles per hour! A large amount of destruction may occur with winds that strong. Roofs may be torn off homes. Buildings may be flattened. Trees topple over. Hurricanes are deadly, but not just because of their winds. They can also produce very heavy rains and huge waves that slam into the coastline. Hurricanes are very common along the east coast of the United States. Here, wind, waves, and rain do the most damage.

Luckily, meteorologists (people who study weather) can forecast hurricanes days in advance by using radar technology. Radar is a little bit like a moving picture. It shows how big storms are and which way they are moving. Radar images people time to prepare for a coming storm. If the storm is very strong, home and business owners will put up plywood to protect their glass windows and doors. People who live along the coast will evacuate. They'll go to a hurricane shelter or stay with friends and relatives who live in safer places farther inland. Many lives are saved every year by people who take the necessary precautions.

Question28. What is a hurricane?

A. a tidal wave B. a huge storm C. a thunderstorm D. a tsunami

Question 29. What makes a hurricane?

A. thunderstorms B. strong winds C. seawater D. the earth rotation

Question 30. What of the following is not correct?

A. A hurricane is very dangerous because it lasts for days and weeks.

B. The hurricane wind speeds per hour can be nearly twice as fast as the wind speeds.

C. A hurricane can reach speeds of at least 74 km per hour.

D. Hurricanes often appear along the east coast of the United States.

Question 31. Who is meteorologist?

A. People study weather.

B. People do businesses in the meteorological field.

C. People live along the coast.

D. People are evacuated from the regions affected by hurricanes.

Question 32. What is radar used for?

A. making moving pictures

B. showing the size of hurricanes and their movements

C. giving people time to prepare for a coming storm

D. All above

Scientists have long struggled with how to measure the effects of climate change on wildlife. This is especially true for birds flying in and out of coastal areas bordering the Arctic Ocean. In the past, researchers depended mainly on information gathered by satellite to follow the movement of birds and animals. But this method can be costly and result in huge amounts of information, which can be difficult to process.

Now scientists are turning to another kind of technology to help them follow birds and other wildlife. Songbirds are especially difficult to study in the wild. They can fly across thousands of kilometers and their bodies are too small for electronic tracking devices.

A new report tells about a project in which researchers recorded songbirds and then put the sounds into a computer program to be studied. The researchers created machine learning algorithms with the ability to focus on bird calls while ignoring other noises. The algorithm helps improve the likelihood of predicting the correct result. Similar machine learning methods have been used to recognize human speech.

Các nhà khoa học từ lâu đã phải vật lộn với cách đo lường tác động của biến đổi khí hậu đối với động vật hoang dã. Điều này đặc biệt đúng đối với các loài chim bay vào và ra khỏi các khu vực ven biển giáp với Bắc Băng Dương. Trong quá khứ, các nhà nghiên cứu phụ thuộc chủ yếu vào thông tin thu thập bởi vệ tinh để theo dõi sự di chuyển của chim và động vật. Nhưng phương pháp này có thể tốn kém và dẫn đến lượng thông tin khổng lồ, có thể khó xử lý. Bây giờ các nhà khoa học đang chuyển sang một loại công nghệ khác để giúp họ theo dõi chim và động vật hoang dã khác. Songbirds đặc biệt khó học trong tự nhiên. Họ có thể bay qua hàng ngàn cây số và cơ thể của họ quá nhỏ cho các thiết bị theo dõi điện tử. Một báo cáo mới cho biết về một dự án trong đó các nhà nghiên cứu ghi nhận loài chim biết hót và sau đó đưa âm thanh vào một chương trình máy tính để nghiên cứu. Các nhà nghiên cứu đã tạo ra các thuật toán học máy với khả năng tập trung vào các cuộc gọi chim trong khi bỏ qua các tiếng ồn khác. Thuật toán giúp cải thiện khả năng dự đoán kết quả chính xác. Các phương pháp học máy tương tự đã được sử dụng để nhận ra lời nói của con người.
