A

I woke up late and had breakfast in a hurry. I had never been late and didn't want my boss to be unsatisfied.

However, it seemed that the day wasn't a lucky one for me from the very second I left my flat. The moment I wanted to rush downstairs, one of my stiletto heels (细高跟) broke. I had to return to change my red shoes. I also had to change my purse and other little things that I had tried to match with the shoes. I was sure I would be late for work.

On my way to work I had to wait for over half an hour because of an accident. I had no choice but to wait. I phoned my boss and he told me that it was no problem, but he needed me for the meeting with the Japanese clients (客户) that morning.

Finally, I arrived at the office one hour later. I had to keep calm and be fresh for the meeting to make the clients sure that our plan was the best for their future business project. However, I left the plan I had made the night before at home and was going to make a presentation (介绍) about it to the clients. I was about to get angry when I realized that I had a copy of it in my office.

At last, the meeting came to an end and it turned out to be a success. But I have to say that I had a terrible day, full of incidents.

Arriving in New York

There are three airports in New York. When you arrive at one of them, you can take a bus or a taxi to any place in New York.

Eating out

There are many kinds of food in New York. And you shouldn't eat at McDonald's every day. There are good restaurants in Little Italy and Chinatown, for example.

Public transport

In New York, there's a good bus and subway service. If you are planning to use the subway a lot, you should buy a subway ticket for the journey because it's cheaper. But you don't have to use the public transport — there are lots of places you can go to on foot, such as the Empire State Building, the 5th Avenue and the Central Park. The New Taxis are a part of the city experience, so you should take at least one taxi during your visit.

Places to see

Finally, there are a lot of places to see in New York — the Times Square, the Statue of Liberty, and so on. And you shouldn't go home without climbing the Statue of Liberty to enjoy the scenery of the city.

Shopping

D. Terrible.

Shopping in New York is fun. There are big shops on the 5th Avenue. They are open seven days a week. But be careful when you look at the prices; you have to pay a special 8% tax (税) on everything you buy in New York.

What you see

Not all films are made in “real” places. When they are, they are shot on location, which means that real streets, trees and buildings are used. However, this can be difficult and expensive, so many films are made in buildings called sound stages. If this is the case, a backdrop(背景) may be carefully painted and hung behind the actors. Backdrops are so good that you often think you are looking at a real place.

There are so many important words that refer to the camera. When the entire screen is full with one image, like someone‟s face, this is called a close-up shot(特写镜头). When the camera moves back and the screen shows a picture from far away, this is called a wide-angle shot(广角镜头). Wide-angle shots are used to show things such as mountains and a river or a city with many streets and buildings.

At the end of a film, the credits(演职人员) appear. They include a list of people who worked on the film and the list of songs you heard in the film, as well as other things.

What you hear

The music which plays in the background while you watch a film is called the

D. $10.

film score. The sounds like raindrops, a doorbell or footsteps in a corridor are called sound effects.

Sometimes, when a film is popular in many countries, people want to hear the and it is recorded over the original talking. This is called dubbing and people describe this kinds of films as „dubbed‟(译制片).
