I am a person who loves to eat, so I often go to restaurants to eat but there is one bad thing I always remember when I go to a restaurant that is not bringing enough money. It's a beautiful day as always. Whenever I have free time, I will stop by this particular restaurant to eat. The restaurant is very nice and the food is always delicious. Before eating, I usually make a reservation, I choose the most vip place and confidently choose the dish. While rummaging through the selection of dishes, I saw a new item that was very beautiful and genuine, but did not look at the price I chose. Who would have thought that later my friend came and I was the one to invite my friend to eat. The food arrived very nice and very fragrant. After a while after I had eaten, I paid the bill, who would have thought. A huge amount of money appeared before my eyes. I took out the money but only half of it. At that time my face was pale and very shy and behind me was a long line waiting. I told them that I didn't have enough money, I thought I would stay and wash the dishes, who would have thought that because I am a regular customer, I can let the next time pay. Luckily for me that time was returned or else I don't know what to do to pay them anymore. And from that meal, I learned the lesson that when I eat, I should save or I'll be happy or miserable.

Last summer , I was allowed to eat lotus buffet by my uncle. At four hundred thousand a ticket , a price not cheap for ordinary people . It is so beautiful there is nothing more to say , attentive service staff , always smiling with guests . There is also a fountain with a lotus pond. It is the ideal place for us to have a delicious meal like mom's cooking. I eat very little seafood , yes , it is the food I hate from the sky to the bottom of the sea ( especially oysters ) . If it's seafood, I only eat two seafood dishes that I don't dislike, the only ones being octopus and squid fried with butter. I ate only sushi , adding some deep fried dishes and a few bowls of soup was enough . Choosing dessert , I ate a greasy cheesecake and reminded me of an indispensable summer dish , which is all flavors of ice cream .

Nowadays testing has an extremely prominent place in education. The preparation required for examinations places limits on teachers as well as considerable amounts of stress on students. While some testing may be necessary to gain a better understanding of what a child has learned, I completely agree that excessive testing is too restricting for teachers. Furthermore, it can actually inhibit students’ learning and potentially be damaging over the long term. Firstly, with the heavy emphasis placed on exams, teachers must teach only to the test. The result of this is that teachers cannot take the time to answer students’ questions about the content. This is because there is only time to teach what is going to be in the exam. This squashes children’s natural interest in subjects. Another point to consider is that studies have shown that any student, regardless of age or subject, needs time to consolidate learning before being tested. A student who is tested too soon may get a low mark which is actually not representative of this student’s learning. Continual testing, therefore, does not take in account students’ natural developmental stages. Finally, the amount of stress placed on students to pass all these exams is not healthy. The continual cycle of preparing for a test and taking a test can exhaust and burn out even the most motivated student. This is particularly dangerous when pupils are still young. It also removes the natural joy that comes from learning for both teachers and students when exams are constantly looming over their heads. In conclusion, although a certain amount of testing will always be required at schools, I firmly believe that the current emphasis placed on tests is unnecessary and could have longterm negative effects on students.

"Education is not just about going to school and getting degree. it is about widening your knowledge and absorbing the truth about life". In today's era the school system is over focused on testing. This results in stress on students about learning, and also teachers seem helpless, and are unable to adapt course to meet the needs of individuals. I am totally argue with the statement, and also give reasons as well as provide possible solutions for this.

To begin with, Teachers are unable to teach students with interest due to lack of timing. School Authorities will pressurize the teachers for completing their syllabus in a particular time. As a result of it, they are unable to give proper information to students. This results in bad performance of students in their exams. For instance, Delhi school community declared that there are still many schools; there intentions is only teach students no matter how much knowledge students gain from teachers. The solutions of this, could be limited test should conducted by school authorities to help teachers teaching the students with full knowledge and self-assureness
