Directions：For this part，you are allowed 30 minutes to write a short essay on the challenges of studying abroad. You should write at least 120 words but no more than 180 words.
With economic globalization and cultural integration go side by side, an increasing number of college students are inclined to study abroad, including senior middle school students.
The challenges of studying abroad can be listed as below. Initially, different habits and customs can cast some unexpected effects on our life. We are not used to living in a completely strange environment. Similarly, teaching philosophy and methods among diverse countries are contradictory sometimes, which is not suitable for juveniles. At last, studying abroad needs huge expense. Not only should our parents take pressure, but also we do heavy part-time jobs after school.
By and large, were it left to me to comment, I would recommend that students are expected to fully consider whether studying abroad is the best choice for themselves and their family.
