Read the passage below carefully and choose the best option A,B,C or D
The start of every New Year is when we make plan to change our life for the better over the fothcoming twelve months. Psychiatry professor Jayashri Kulkami says “ January 1st is a “ magical” date and a vow made on this day is more powerful than one made on June 1st, for example.” So, we make a list of things to quit, start or change. Unfortunately, most of these promises are, more often than not, broken by January 31st. They are usually the identical resolutions that were not fulfilled from the previous year, and the years prior to that.
Researchers show 45 percent of us make a new year resolution. The most common vows include losing weight, volunteering to help others, quiting smoking, saving money, and getting fit. Others include eating healthier food, drinking less alcohol, and going on overseas trips. However, researches also show that most of us are not so goood at sticking to these. A study from the University of Scranton reveals that 71 percent stick to our annual promises for the first two weeks; six months later, less than 50 percent are still on track to keep their resolutions. Most people who give up on their resolutions do so because of a lack of willpower and the use of the “ escape clause” that they will “ try again next year”

Ai vs giúp mik vs ạ!! Mai mik phải nộp bài test r mà k bk tl như nào
I have Learned, often the hard way, that there are a few simple rules about how to make life easier both before and after your journey. First of All, always check and double-check departure times. It is amazing how few people really do this carefully. Once i arrived at the airport a few minutes after ten. My secretary had got the ticket for me and i thought she said that the plane left at 10:50. I walked calmly to the departure desk, thinking I still had a little time to spare. I didn`t bother to take a good look at the ticket. The clerk at the desk told me politely but firmly that the departure time was 10:15 and that the flight was, according to international regulations, " now closed! ". I had to wait three hours for the next one and missed an important meeting.
The second rule is to remember that even in this age of credit cards, it is still important to have at least a little of the local currency with you when you arrive in a country. This can be absolutely essential if you are flying to a place few tourists normally visit. A few years ago, I took a business trip to Oklahoma. I flew there from London via Dallas,with very little time to change planes in between. I arrived there at midnight and the bank at the airport was closed. The only way to get to my hotel was by taxi and since I had no Dollars, i offered to pay in Pounds instead." Listen, Buddy! I only take Real money! " the driver said angrily. Luckily I was able to borrow a few dollars from a clerk at the hotel, but it was Embarrassing.
The third and last rule is to find out as much as you can about the weather at your destination before you leave, especially if you can take only a little baggage with you. I feel sorry for some of my colleagues who travel in heavy suits and raincoats in May, when it is still fairly cool in London or Manchester, to places like Athens, Rome or Madrid, where it is already beginning to get quite warm during a day. Few people understand just how important it is to have the right sort of clothes with you in these days of rapid air travel.
I. Discuss these questions. Campare your answers.
1. Explain why the writer once arrived at the airport only a few minutes before the plane left.
2. Whose fault do you think it was? Thư writer's or his secretary's? Give reasons for your answer.
3. Explain why the writer think it is essential to have at least a little local currency when you arrive in a foreign country.
4. Describe some of the problems you could have if you ignore the advice in the last paragraph
