LESSON ONE OF THE CONDITIONS OF THE LOVE OF THE PEOPLE

Patriotism - that is the source of the nation. Since his father also established the country, keep the country until now peace build the country, our patriotism is still intact. I love the water in a way that suits each time. Because really the patriotism of our people passionately passionate.

Have you ever wondered what is patriotism? Patriotism is love for the country, the country; Effortless effort to build and develop the country more and more powerful. Speaking of patriotism, it's not something high, far away, but very close. One sentence saying "I love my country" is the patriotic spirit. A little support for the highland is also patriotic. Simple love, it's so simple, it's close to us every day for hours.

Each time we have a different spirit of patriotism. In the past, our people loved the country by protecting the country. There are many people sacrificed for the country to keep each island, each island of the island: from the king he established An Duong Vuong, Ngo Quyen, from the skillful general commanded an entire army. Tran Hung Dao, Ly Thuong Kiet, poets use literature to express the patriotic spirit as Nguyen Trai, the national heroes Vo Thi Sau, ... the soldiers of the lake do not bear suffering, difficult and not. lack of strength, solidarity of our people - a great demonstration of patriotism.

At the time of bloody war, when the country was at peace, every minute of every second we were surrounded by people who were trying hard to learn to contribute to the national construction: Only building solid buildings, hard-working teachers teach students to help the country with talented people ... Every month there are people who bring glory, proud of the country. U23 Vietnam goes down in history as the heroes of the grass field, bringing glory to the nation so many people see the love and glory. Prof. Ngo Bao Chau is internationally recognized to affirm Vietnamese talent ... That's right, these are the actions that demonstrate the patriotism of our people.

We are the people of our homeland, we grow up thanks to our homeland. If there is no homeland, there will probably not be us. Therefore, our patriotism has been penetrating us since childhood. It is natural to instill in me. The spirit follows us from small to large and grow stronger day by day, blooming more.

Thinking about the patriotism many people think that only when fighting guns, only when standing up to kill foreign invaders patriotism. But true love is not just big things. Patriotism is always present in our society. I go to work, go to school is to build the country's development. We promote the activities of the country as football, badminton, volleyball on the international arena, it is also patriotic. We preserve historical culture is also the patriotic spirit.

We are young people, the preschool of the country, so we have different ways of expressing our patriotism. But first of all, as President Bao said: "Non Vietnam River has become beautiful or not, the Vietnamese people are comparable to the five continents, it is thanks largely to the study of "Education is the first source of contribution to build the country. Learning helps us to contribute talent, contribute talent to the country. We are not only learning but we have to know the smallest actions of loving people around us, sharing the sorrows and joys with others.

We, the preschoolers of the country, show our patriotic spirit is always burning, always exist.

Read the passage below carefully, and then choose the best answer

Conservation conflicts arise when natural-resource shortages develop in the face of steadily increasing demands from a growing human population. Controversy frequently surrounds how a resource should be used, or allocated, and for whom. For example, a river may supply water for agricultural irrigation, habitat for fish, and water-generated electricity for a factory. Farmers, fishers, and industry leaders vie for unrestricted access to this river, but such freedom could destroy the resource, and conservation methods are necessary to protect the river for future use.

Conflicts worsen when a natural resource crosses political boundaries. For example, the headwaters, or source, of a major river may be located in a different country than the country through which the river flows. There is no guarantee that the river source will be protected to accommodate resource needs downstream. In addition, the way in which one natural resource is managed has a direct effect upon other natural resources. Cutting down a forest near a river, for instance, increases erosion, the wearing away of topsoil, and can lead to flooding. Eroded soil and silt cloud the river and adversely affect many organisms such as fish and important aquatic plants that require clean, clear freshwater for survival.

Question: What is the passage above mainly about?

A. Natural-resource shortages

B. Agricultural irrigation

C. The headwaters of a major river

D. Conservation conflict
