Our environment is at stake. Water, air pollution, forest fires ... are getting more and more serious. And this will significantly affect our life. Therefore, each person needs to have a sense of environmental protection. In particular, schools and students also need to raise their awareness. As students, we can do small things to protect the environment such as disposing of trash in the right place, not littering. We can have street cleaning sessions. In addition, students also need to propagate to people not to litter waste indiscriminately, propagate about the harmful effects of environmental pollution. On the side of the school, there should be rules about school sanitation, organizing for students to clean the school so that it is always clean. The above are things that students and schools can do to protect the environment. Let's join hands for a clean environment

Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash.

Chemical contamination, or nutrient pollution, is concerning for health, environmental, and economic reasons. This type of pollution occurs when human activities, notably the use of fertilizer on farms, lead to the runoff of chemicals into waterways that ultimately flow into the ocean. The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans. The negative effects on health and the environment caused by algal blooms  hurt local fishing and tourism industries.

Marine trash encompasses all manufactured products—most of the plastic—that end up in the ocean.  Littering, storm winds, and poor waste management all contribute to the accumulation of this debris, 80 percent of which comes from sources on land. Common types of marine debris include various plastic items like shopping bags and beverage bottles, along with cigarette butts, bottle caps, food wrappers, and fishing gear. Plastic waste is particularly problematic as a pollutant because it is so long-lasting. Plastic items can take hundreds of years to decompose.

This trash poses dangers to both humans and animals. Fish become tangled and injured in the debris, and some animals mistake items like plastic bags for food and eat them. Small organisms feed on tiny bits of broken-down plastic, called microplastic, and absorb the chemicals from the plastic into their tissues. Microplastics are less than five millimeters (0.2 inches) in diameter and have been detected in a range of marine species, including plankton and whales. When small organisms that consume microplastics are eaten by larger animals, the toxic chemicals then become part of their tissues. In this way, the microplastic pollution migrates up the food chain, eventually becoming part of the food that humans eat.

Solutions for marine pollution include prevention and cleanup. Disposable and single-use plastic is abundantly used in today’s society, from shopping bags to shipping packaging to plastic bottles. Changing society’s approach to plastic use will be a long and economically challenging process. Cleanup, in contrast, may be impossible for some items. 

Nonetheless, many countries are taking action. According to a 2018 report from the United Nations, more than sixty countries have enacted regulations to limit or ban the use of disposable plastic items.

Volunteering activities play a crucial role in fostering empathy, strengthening communities, and promoting personal growth. By dedicating time and effort to causes that matter, volunteers not only contribute to the well-being of their communities but also develop a sense of purpose and fulfillment. They acquire new skills, broaden their perspectives, and build meaningful relationships. In terms of communication, clarity, empathy, and active listening are key. To help others, one can offer emotional support, share useful information, or simply lend an ear to those who need to be heard. Communication can also be used to raise awareness about important issues, mobilize resources, or coordinate community efforts. Remember, every small act of kindness can make a big difference. So, let’s use our words and actions to create a positive impact.

1)History was my favourite subject in my academic year and I have learned so many things from the history books I read and learned from teachers related to history and they were so interesting that I later did my graduation majoring History.

Learning about the past history is something that gives us real knowledge about our country, the world and about the human race. I read History in my grade 7 and found it very interesting. This subject taught us about the past of your world, how the social and economic condition was and how the world has been shaped by the different events throughout the time. After that, I become so interested in this subject that I started reading books on History from different writers. There is a famous saying that "to shape the future you must know the past" and history teaches us that. I had been lucky to have some great teachers who have a tremendous way of explaining the topics of History. To me, other subjects like literature and Math were also interesting but I felt a different passion on History.

After I finished my school, I took History as my major and that has greatly influenced me the way I look at the world and to the past and future. Reading and learning history was like travelling through time and generations that excited me so much.

2)Would your students benefit from participation in a study group? Are you too busy to organize and supervise study groups for students in your courses? I’m guessing the answer to both questions is yes. If so, here are some ways teachers can encourage and support student efforts to study together without being “in charge” of the study groups.

Promote study groups – First, include a list of reasons why students should join study groups in the syllabus or on the course website. Maybe there’s a short podcast available in which you talk about the usefulness of study groups. Better yet, if you’ve got some students who studied together in a previous course, ask them to make some comments about their experiences. Second, talk regularly in class about study groups. You can repeat all the benefits, suggest activities that involve good group study strategies, or propose some things they could study together (like problems they could solve, questions they could discuss). You also can solicit feedback from study groups in class or mention content you discussed with a group during office hours.

Make study groups an option – Encourage students to organize their own groups, but offer to help with the process. Nudge them with reminders, such as “Send me an email if you’re interested in being part of a study group.” Have study groups “register” their members, and then report on meeting times and activities. Suggest study activities for the group (ideas like those offered in the next item). Invite the group to meet with you during office hours or to send questions electronically. Offer registered study groups that report regular meetings a bonus point incentive depending on the average of their individual test grades. Let all students know that joining a study group is an option throughout the course.

Demonstrate the value of a study group – Too often when students study together, it’s pretty much a waste of time. If they’re reviewing for a test, they talk about how it can’t possibly be that hard and thereby relieve themselves of the need to study. Or they “go over” their notes, reading what they’ve written but never with any discussion. Group studying is too often accompanied by eating, texting, and regular side conversations.

In order for students to get the most value from their study sessions, you’ll need to help them come up with a different set of strategies. You can do so by holding a review session and asking students to form potential study groups (it’s up to them if they want to meet as a group more often). Give the groups tasks like these: 1) For three minutes everybody reviews their notes and lists five things they think will be on the test and then for five minutes they share lists and create a group list of the items most often mentioned. During the exam debrief, students revisit their list of things they expected to see on the exam. Were those things on the exam? 2) Everybody takes three minutes and writes a question about some content they don’t understand or wish they understood better. The group devotes a specified amount of time to each question, looking for relevant content in their notes and the text. 3) The group has 20 minutes to make one crib sheet that everyone in that group can use during the exam.

Offer proof that study groups improve performance – Compare the scores, points, or grades of those working in study groups with those who aren’t. These are data which should be collected across several sections of the course.

Define study groups broadly – Students tend to think of study groups for exam preparation, but that isn’t the only kind of student collaboration that promotes learning. If there are regularly assigned readings for the course, students can get together to discuss the reading. Again you might let them do this first in class with a good set of prompts so they see how dialogue can enrich and deepen their understanding of the assigned material. Readings are easily discussed in virtual environments, which means the group doesn’t have to find a time when everybody can meet. If various writing assignments are required in the course, students can form peer editing groups. Rubrics, checklists, and prompts can help them get beyond superficial feedback (“you might need a comma here”) to the kind of helpful critique that improves the writing.

I usually get up at 5:30 in the morning. After washing my face and brushing my teeth, I do morning exercises for fifteen minutes. Then I have breakfast with Mum and Dad at 6:15 and leave home for school at 6:30. My classes start at 7:00 and end at 11:15. After that I go home, and have lunch with my family at 12:00. After lunch I usually have a short rest. I study my lessons , read books, and do homework from 1:30 p.m. to 4:00 p.m. I often play badminton with my friends on the ground at 4:30. I come back home and have dinner at 6:00 p.m. After dinner, I often watch the news on TV for thirty minutes. Then I prepare for the new lessons and go to bed at 10:30 p.m
