The given diagram indicates information about how used glass bottles are recycled.

In general, it can be seen that there are three stages in this process, commencing with the collection of used bottles, and culminating with newly recycled bottles used for storing drinks to be sold in supermarkets.

At the first stage of the process, glass bottles are used by customers and gathered at a collection point before being delivered to a cleaning plant by a truck. The second stage begins when the bottles are washed with high-pressure water, and subsequently sorted based on their colour (green, brown and clear). After that, the bottles are broken down into pieces in a glass factory and melted in a furnace to form a liquid. The recycled liquid glass is then mixed with new liquid glass and poured into a mould to form new glass bottles.

During the final stage of the process, the recycled bottles are filled and packaged, and then transported to supermarkets to be sold.

Many teachers hold the view that international exchange programs would bring benefits to all teenage school students. In my opinion, although such programs can be disadvantageous to students to a certain extent, I believe that the advantages are still more significant.

To begin with, the biggest difficulty for students when attending an exchange program is the financial burden on their families. More specifically, many parents whose income is at a low or average level may struggle to cover tuition fees and daily living expenses for their children, especially when students study in a developed country. To make mater worse, students who travel to another country through an educational exchange program would not receive the medical coverage like the local people. Therefore, if an exchange student happens to encounter a serious health problem during their stay, it will cost their family a fortune to cover the cost of healthcare services and medications in a foreign country.

However, there are numerous benefits that can be gained from international student exchange programs. Firstly, studying abroad allows students to significantly improve their foreign language skills. In fact, when studying in a new country, students will have the perfect opportunity to engage in conversations with their classmates and teachers, in both academic and general contexts on a daily basis, which is the perfect condition for them to improve their language skills. Furthermore, studying in a developed country often gives students access to more modern and effective facilities and methods of learning. Finally, although studying abroad can be costly, all international students have equal opportunities to apply for scholarships and financial aid from the host country to ease such financial burdens.

In conclusion, though financial problems may cause some difficulties for students and their families when participating in international exchange programs, the positive aspects that such programs bring to students are well-worth the cost.
