Work in pairs. Say how a forest fire may start and what every camper ought to remember. (Làm việc theo cặp. Hãy nói xem một đám cháy rừng có thể bắt đầu như thế nào và mỗi người cắm trại cần ghi nhớ điều gì.)

Guide to answer

A forest fire can start with a small burning cigarette butt, or with a burning campfire near a heap of dry leaves or grass. Sometimes a lightning can cause a forest, too.

Every camper ought to remember to put out the campfire before he leaves the place by covering it with earth. And another thing they should keep in their mind is they should not make a campfire near heaps of dead leaves or grass, especially in the very dry weather.

Have you ever seen a forest destroyed by fire? A great forest fire is an awful thing to see. Once a fire has started, it spreads quickly. Foresters say that late summer is the season when fire is the greatest danger to woods and foresters.

They are very dry then. Sometimes when the danger of fire is very great, foresters will not allow anyone to go into the forests.

If people leave a campfire burning near a heap of leaves, this often causes a forest fire. Campers must always remember to put out their campfire and cover the place with earth. It is the duty of every camper to take the greatest care not to start a forest fire.

Anyone careless enough to start a forest fire has done something, which makes life more difficult for all of US. Every fire destroys valuable wood, wild life, and good soil. Everyone of US must know how important it is to care for our great forests and save them from fire.

• Câu 1: Read the passage carefully and choose the correct answer

  Our family members resemble each other because we have the same genetic formation in our DNA, and this formation has been passed from parents to children for many generations. Much like the children humans create, plants pass on their genetic formation in their seeds. The seeds of endangered and imperiled plants are so valuable because there are no other plants in the world with that same genetic formation, and we are at risk of loosing these genetic resources forever. But preserving the genetic diversity of some species can be quite difficult. When researchers and conservationists preserve a plant, one of their goals is to preserve genetic variety. “By preserving the genes of these plants, we preserve the possibility for adaptations in the future,” explains Dr. Christina Walters, a plant physiologist. After collected seeds must be stored for future use, planting or research. Since seeds begin to grow when it is warm and wet, scientists store seeds in places that are cold and dry, which is called a seed bank. But not all seeds survive the drying and freezing treatments, and care must be taken so that they are not harmed during banking. When researchers attempt to store a seed, they examine what is known about the growth habits of the plant, its habitat and geographical distribution, and then classify the seeds by storage needs.
