Câu VIII. Đọcđoạnvănsauvàchọncâutrảlờiđúngchocáccâuhỏi.(0,8điểm) It is often considered that the schoolyard is where bullies go to make other kids a miserable school life, but a new study suggests that classrooms are another popular place.

A bit more than half said they had been laughed atin an unfriendly way, and half reported being called hurtful names. About one third said groups had excluded them to hurt their feelings. 28% said their belongings had been taken or broken; 21% said someone had threatened to hurt them. According to the results, two-thirds of the students said they had been bullied in more than one way over the previous month. The study authors mentioned that 8% of the students who answered said they had missed school at least once during the school year because of fear of being bullied. 25% said they had taken other actions, such as missing recess, not going to the bathroom or lunch, missing classes, or staying away from some area of the school to escape from experiencing a bully.

Câu VII. Đọcđoạnvănsauvàtrảlờicáccâuhỏi.(0,8điểm) Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on house roofs, so no new space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages. Wind and water power rely on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime. However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cells require large area to work effectively. The main disadvantage of solar energy is that it costs about twice as much as traditional sources such as coal, oil, and gas. This is because solar cells are expensive. Scientists are hoping that the costs of solar cells will reduce as more and more people see the advantages of this environmentally friendly source of energy. 1. Where can we install solar cells to generate solar energy: on house floor or the house roofs? 2. What are the disadvantages of wind and water power? 3. Do solar cells require much maintenance? 4. Which is more expensive, solar energy or traditional sources of energy?
