Đề bài

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.

              Plants are subject to attack and infection by a remarkable variety of symbiotic species and have evolved a diverse array of mechanisms designed to frustrate the  potential colonists. These can be divided into preformed or passive defense mechanisms  and inducible or active systems. Passive plant defense comprises physical and chemical  barriers that prevent entry of pathogens, such as bacteria, or render tissues unpalatable or toxic to the invader. The external surfaces of plants, in addition to being covered by an epidermis and a waxy cuticle, often carry spiky hairs known as trichomes, which either prevent feeding by insects or may even puncture and kill insect larvae. Other trichomes are sticky and glandular and effectively trap and immobilize insects. If the physical barriers of the plant are breached, then preformed chemicals may inhibit or kill the intruder, and plant tissues contain a diverse array of toxic or potentially toxic substances, such as resins, tannins, glycosides, and alkaloids, many of which are highly effective deterrents to insects that feed on plants. The success of the Colorado beetle in infesting potatoes, for example, seems to be correlated with its high tolerance to alkaloids that normally repel potential pests. Other possible chemical  defenses, while not directly toxic to the parasite, may inhibit some essential step in the establishment of a parasitic relationship. For example, glycoproteins in plant cell walls may inactivate enzymes that degrade cell walls. These enzymes are often produced by bacteria and fungi.

            Active plant defense mechanisms are comparable to the immune system of  vertebrate animals, although the cellular and molecular bases are fundamentally different. Both, however, are triggered in reaction to intrusion, implying that the host has some means of recognizing the presence of a foreign organism. The most dramatic example of an inducible plant defense reaction is the hypersensitive response. In the hypersensitive response, cells undergo rapid necrosis ― that is, they become diseased 

and die ― after being penetrated by a parasite ; the parasite itself subsequently ceases to grow and is therefore restricted to one or a few cells around the entry site. Several theories have been put forward to explain the bases of hypersensitive resistance.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.

In the 1970s, many people became concerned about energy. People has to face up to the fact that they used too much energy, and energy sources were not going to last forever. One architect, Michael Reynolds, decided to do something. He set out to design homes that were cheaper to build and more energy-efficient. In addition, he wanted to do something about all the garbage. Finally, he came up with the idea of “earthships.”
Although it sounds like a boat, an earthship is a house. However, unlike regular houses, earthships are constructed from garbage and are built using only ten percent of the energy needed to build a typical house. Moreover, after they are built, earthships use only ten percent of the energy required to heat, light, and cool a regular home. Although earthships sound unique, they can actually be built to look just like any other house.
One of the big benefits of earthships is that they are made from recycled materials. The main construction material of an earthship is used tyres that are filled with dirt. The dirt-filled tyres are then laid flat and stacked like bricks. Because the tyres are round, there is lots of extra space between the columns of tyres. These spaces are filled with used cardboard. The tyres and cardboard form the outside walls of an earthship. The inside walls between rooms in the earthship do not need to be as strong as the outside walls; therefore, the inside walls are made with old cans, bottles, and cement that are eventually covered and painted to look just like walls in a typical home.
Another benefit of an earthship is that it saves energy and natural resources. For example, an earthship uses less water. Rain water, which is collected on the roof, is used for drinking and bathing. Furthermore, earthships need much less energy for heating and cooling because they are built into the ground, which keeps the temperature inside the house from getting too hot or too cold. In the long run, this helps earthship owners lower their utility bills. As well, one wall of an earthship usually faces south. Therefore, solar heat helps to warm the house, and solar panels built on the roof generate electricity to run appliances in the house.
All of these features make earthships very environmentally friendly. That’s one of  the reasons they have become popular throughout the world. Earthships have been built in Bolivia, Australia, Mexico, Japan., Canada, England, Scotland, and all over the YS. Maybe in the near future, an earthship will be landing near you!
