Does this situation seem familiar to you? Your English is progressing well, the grammar is now familiar, the reading comprehension is no problem, and you are speaking quite fluently.1.
First of all, remember that you are not alone. Listening is probably the most difficult job for almost all 
learners of English as a foreign language. The most important thing is to listen as often as possible.2. The Internet is really a useful tool for English students. You can download The RealPlayer from RealMedia.com. The RealPlayer allows you to use the Internet like a radio station.
Once you have begun to listen on a regular basis, you might still be frustrated (受阻)by limited understanding.3.
Here is some of the advice I give my students:
●Accept the fact that you are not going to understand everything.
●Stay relaxed when you do not understand, and try listening to the material for more times.
● Do not translate everything into your native language.
●4. Don't concentrate on details before you have understood the main ideas.
● Listen to something you enjoy.
I remember the problems I had in understanding spoken German when I first went to Germany. In the
beginning, when I didn't understand a word, I insisted on translating it in my mind. This method usually resulted in confusion.5.Firstly, translating creates a barrier(障碍) between the listener and the speaker. Secondly, most people repeat themselves constantly. By remaining calm, I noticed that even if I didn't pay much attention I could usually understand what the speaker had said.
A. But you can't follow a native English speaker at all!
B. What should you do?
C. But listening is a problem for most of the beginners!
D. However, after several weeks, I got used to the new environment in Germany.
E. So, what you need to do is to find listening resources.
F. Then, after the first six months, I discovered two extremely important facts.
G. Listen for the general idea of the conversation.

With fuel costs rising and airlines finding more fees to impose （强加，征税）on travelers every day, airfare isn’t getting any cheaper. Since you can’t drive to all your dream destinations, flying is the only way to go sometimes and, undeniably, the fastest. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.
Get the best fare. Airlines put out their fare sales on Tuesday morning, making this day the best day to book a flight for less.
Fly during the least popular times. Tuesday, Wednesday and Saturday are the slowest days to fly, which means cheaper deals than the rest of the week. You can also find reduced rates on early morning flights, since many people don’t like to get up before the sun to get to the airport. Earlier boarding times can also considerably cut down your chances of getting bumped on an overbooked flight or delayed because of other delayed flights or mechanical issues.
Choose your seat later. Some airlines charge you to pick your seat when you book online, adding even more to the bottom line of your ticket cost. If you show up early on your travel day, you can still get suitable seats. Some of the best seats get held back until flight day, unless others are willing to pay extra for them ahead of time, so you still have the chance at one of those.
Fly on holidays. You already know that summer is the most expensive time to fly, and even though most other times are more affordable, the days surrounding holidays can be crazy. Save big if you’re willing to travel on major holidays, such as Thanksgiving and Christmas.
Don’t wait until the last-minute to book. Many travelers don’t know that there’s a sweet spot for booking and getting the best price on your tickets. Book too early or too late and you could end up paying more than you need to. The best time to book is between three months and six weeks from when you want to travel.
1.The passage is intended to _______.
A. inform us how to book a cheaper ticket
B. tell us how to choose the seat and time for a flight
C. persuade us into travelling by air
D. inform us of some best ways to save money on a flight
2.Which of the following statements is not true?
A. Airline travelers are supposed to pay more for the rising fuel costs
B. Early morning flight will help avoid some bumps and delays.
C. You can only book your seat online before or on your flight day.
D. Booking too early may cost you more money on your tickets.
3.Which is the best time to book the flight for October 2nd?
A. May 15th B. August 15th
C. June 15th D. September 15th

Some people will do just about anything to save money. And I am one of them. Take my family’s last vacation for example. It was my six-year-old son’s winter break from school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York, so I had to get back. But that didn’t mean my husband and my son couldn’t stay. I took my nine-month-old and took off for home.
The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged---okay, ordered them to wait it out at the airport, to “earn” more Delta Dollars. Our total take: $1,600. Not bad, huh?
Now some people may think I’m a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.
I've made a living looking for the best deals and exposing the worst tricks. I have been the consumer reporter of NBC’s Today Show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.
I tell you this because there is no shame in getting your money’s worth. I’m also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn’t hesitate to spend on a good haircut. It keeps longer, and it’s the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.
1.Why did Delta give the author’s family credits?
A. They took a later flight.
B. They had early bookings.
C. Their flight had been delayed.
D. Their flight had been cancelled.
2.What can we learn about the author?
A. She rarely misses a good deal.
B. She seldom makes a compromise.
C. She is very strict with her children.
D. She is interested in cheap products.
3.What does the author do?
A. She’s a housewife. B. She’s a writer.
C. She’s a media person. D. She’s a business woman.
4.What does the author want to tell us?
A. How to expose bad tricks. B. How to reserve airline seats.
C. How to spend money wisely. D. How to make a business deal.

Have you ever wondered?
（1）Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet(喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when the air moving with the wind than in the opposite direction.
（2）What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed moving at over a thousand miles per hour. If you turn something round your head on a string, it goes around in a circle until you let go of the string. Then it flies off in a straight line. “Switching off” gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things would fly off into space.
1.What information can we get from the first passage?
A. It is the jet stream that affects how fast airplanes fly.
B. Planes go slower when they are moving with the wind.
C. It takes more time to fly from NY to London than from London to NY.
D. The jet stream always blows from the east to the west across the Atlantic.
2.The word “shoot” underlined in the 2nd paragraph probably means“________”.
A. send for B. move quickly C. come out D. grow quickly
3.It can be inferred that without gravity ________.
A. buildings and other structures would float away
B. trees and buildings would not so easily fly off
C. something around your head would not float away
D. everything outside buildings would fly off into space
4.Where can we most probably read this text?
A. In a research paper. B. In a short story.
C. In a travel magazine. D. In a students’ book.

For a long time in history,numerous scholars have asked the question:what is beauty?As designers update the latest fashions and artists create their masterpieces,what is considered beautiful changes at an alarming pace.Fifty years ago,the full-figured American actress Marilyn Monroe was a symbol of the American aesthetic（美学的）value; today,many Hollywood actresses different in appearance from Marilyn’s have taken her taken per place.However, aesthetic values not only differ from generation to generation,but do so along cultural lines as well.Often,what is considered hating one civilization is just the aesthetic appeal in another.Thus it is difficult to give an absolute definition of beauty.
As fundamental physicists,my colleagues and I like to believe that we are involved in a search for a beauty that affects definition.The beauty that we search for is not what is set up through the work of people and subject to the tastes,but rather what has been laid down by nature Physics allows its students to look past outer appearance,into a deeper beauty.As a human being,I am attracted by the visual appeal of a wave crashing on the beach.As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon.
In truth,since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe,aesthetics,have become a driving force in modern physics.Einstein and other later physicists have discovered that:Nature,as its most fundamental level,is beautifully constructed.The extraordinary simplicity of the laws that govern the universes is really breathtaking.As Einstein said, it would seem more likely that we should find ourselves living in a "disorderly world,in no way apprehensible through thinking".Yet we are now closer than ever to a full understanding of the universe's beautiful clockwork.As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels, we find that the beauty itself becomes much deeper.
1.The reference to" Marilyn Monroe" in paragraph 2 mainly serves to .
A. show there is no fixed definition of aesthetics
B. provide an example of today's beauty standards
C. compare traditions of the East to the west
D. discuss her abilities as an actress
2.When appreciating a wave crashing on the beach,a physicist sees the beauty of .
A. the visual attraction B. the powerful sounds
C. the lovely creatures D. the physical laws behind
3.Why are Albert Einstein's words mentioned in paragraph 3 ?
A. To detail the functions of physical laws.
B. To highlight the range of Einstein's influence.
C. To stress the very simplicity of the laws of the universe
D. To show that Einstein doubted the beauty of physics.
4.the passage is mainly to .
A. emphasize the influence of physics
B. present a special way of seeing beauty
C. discuss the awareness of across-culture
D. argue the traditional ideas on value
