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.

Since the world has become ............ (industry),there has been an increase in the number of animal species that have either become extinct or have neared extinction. Bengal tiger, for instance, which once roamed the jungles in vast number, now only about 2,300 and by the year 2025, their population is ............ (estimate)to be down to zero. What is alarming about the case of the Bengal tiger is that this ............ (extinct) will have been caused almost entirely by poachers who according to some sources, are not interested in material gain but in ...........(p gratification. This is an example of the callousness that is part of what is causing the problem of extinction. Animals like Bengal tigers as well as other endangered species are a valuable part of the world's ecosystem. .................(nation) laws protecting these animals must be enacted to ensure their .......(survive) and the survival of our planet.
Countries around the world have begun to deal with the problem in ..........(vary) ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission to help defray the costs of maintaining the parks and they often must also depend on world organizations for support. With the money they get, they can invest in equipment, and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective but it will not, by itself, prevent animals from being hunted and killed.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

A new university without a library has recently opened in the USA. All the information normally found in a library is now stored in the university's computers. Without leaving their computers, users can send messages and receive information through telephone lines. However, this means that each student must have access to a computer, and many universities are making this a requirement for freshmen. College campuses now have computer jacks in every part of the university. Study is no longer restricted to just one location.

Computer bulletin boards are used in the same way as traditional ones in schools and colleges. The difference is that over 20 million people may have access to them. If students want to discuss math at 3 am, it's not a problem. They post messages on the bulletin board and find other people who want to talk about the same topic.

Technology now means students can get a degree without being on campus. There are people who are skeptical about this new method of education, but their concerns have had little impact.

Một trường đại học mới mà không có thư viện gần đây đã được mở ở Mỹ. Tất cả các thông tin thường tìm thấy trong thư viện bây giờ được lưu trữ trong các máy tính của trường đại học. Không để máy tính của họ, người dùng có thể gửi tin nhắn và nhận thông tin qua đường dây điện thoại. Tuy nhiên, điều này có nghĩa là mỗi học sinh phải có quyền truy cập vào một máy tính, và nhiều trường đại học đang làm cho một yêu cầu này cho sinh viên năm nhất. Các trường đại học bây giờ có các lỗ cắm máy tính trong mọi phần của trường đại học. Nghiên cứu không còn giới hạn ở một địa điểm.

Bảng thông báo bằng máy tính được sử dụng giống như các bảng truyền thống trong các trường học và cao đẳng. Sự khác biệt là hơn 20 triệu người có thể truy cập vào họ. Nếu học sinh muốn thảo luận về toán vào lúc 3 giờ sáng, thì đó không phải là vấn đề. Họ đăng tin nhắn trên bảng tin và tìm những người khác muốn thảo luận về cùng một chủ đề.

Công nghệ bây giờ có nghĩa là sinh viên có thể có được một văn bằng mà không có trong khuôn viên trường. Có nhiều người hoài nghi về phương pháp giáo dục mới này, nhưng mối quan tâm của họ ít có tác động

Do you think the animals can understand each other? The answer is yes. They can communicate to each other by signs and sounds. For example, dogs communicate in many ways. They not only bark, even they howl, growl, snarl, and whine. They lift a paw, or bare their teeth. Other dogs can understand what these sounds and actions mean_.
Animals communicate with each other not only with sounds and movements but with smell. Most animals that live in herds depend on smell to keep together. And, of course, we know how dogs recognize each other by smell.
Apes are supposed to be among the most intelligent of animals, yet, they really have no better “language” than other animals. They make many sounds and expressions of the mouth to communicate their feelings of anger or hunger or joy, but they have nothing like the words of human speech.
By the way, unlike human beings who have to learn how to talk, apes and other animals know their “language” by instinct. They will make the right kind of cries and sounds and expression even if they have never seen another animal like themselves before.
Birds, however, learn their way of singing, at least in part. That is why a sparrow brought up among canaries will try to sing like one. It has been learning the wrong “language”!

Everyone knows that honeybees make honey, but how do they actually do it? Honeybees live in colonies, which means that they live with lots of other bees. Beehives, nests made of wax, are the places where they live and stow their honey.

Honeybees drink nectar from flowers or other sweet deposits from plants or trees. The honey made by these bees is used to supply the colony with food during the cold winter when there arc no flowers to drink from. Thus, these bees not only consume the nectar for nourishment but also bring it home. They have a special organ called a honey stomach which is used to carry the food to their colony.

When honeybees come back home, they regurgitate what they have put in their honey stomachs. Other honeybees in the hive come along and help them. They repeatedly eat and regurgitate many times until the product becomes somewhat digested. Next, the bees move the syrupy product into open honeycomb cells. Then they beat their wings to fan it to prevent fermentation. The fanning makes the water evaporate so that the product gets thick enough. Now it cannot easily be attacked by bacteria. Finally, it can be called honey. After this process, honeybees seal up the honeycomb cells with wax until they are hungry.

The most impressive part of this process is how seamlessly a bee colony works together. In a colony, there are female worker bees, male drones, and one queen bee. Although there are both male and females in the hive, the majority of the work is done by females. The female worker bees are in charge of taking care of the hive and creating honey. When they are young, they take care of feeding the young bee larvae. When they are older, they go out and bring nectar back to the hive, where they begin making honey. The male drones are responsible for fertilizing the eggs, but require little energy as they spend their time waiting around the hive. The single queen bee is responsible for the colony's survival. She is the only female that can lay eggs. The wonderful substance called honey would not exist without the bees' teamwork.

1. What is the main topic of the passage?

A. The role of the female honeybee
B. Preventing fermentation in honey
C. Why honeybees build huge wax nests
D. How a honeybee colony works to make honey

2. What can be inferred from the passage about honey? A. It's not always the same color
B. It is only liked by a minority of people
C. Watery honey can go bad easily
D. It is created and cared for by the queen bee 3. What do honeybees do to prevent fermentation? A. Blow air on the honey by waving their wings
B. Overproduce honey using their legs
C. Feed the larvae the unfermented honey
D. Bring the honey to the honeycomb cells 4. According to the passage, which of the following is NOT true of honeybees? A. They work together in their colony.
B. They produce honey through a complex process
C. The queen bee is responsible for making honey
D The worker bees work both inside and outside of their hive.
