It is a hot summer day，and you feel thirsty A friend gives you a glass of cold lemonade．How do you feel when you see the glass? Will you describe your feeling as happiness or as pleasure? I believe you will say it is a feeling of pleasure．There is a connection between these two kinds of feelings，and sometimes one causes the other，but they are not the same．Pleasure is more dependent on the five senses while happiness is independent of them．
When you are happy，little unpleasant events usually do not disturb you．When you are unhappy，you feel as if everything is against you．You may compensate for it by eating chocolate and sweets because this gives you pleasure；yet you stay unhappy．A person may smoke cigarettes
because it gives him pleasure，yet，this does not make him happier，especially if he knows the fact that it is not good for his health
The physical world is always in a changing state．At each moment a new thing is being created，changed，transformed and then destroyed. This is the normal state of things and no one call change it．If we stay still in a certain state，we are sure to experience unhappiness sooner or later．On the other hand，if we adjust to the environment，nothing can influence our moods．Then outer events have nothing to do with our inner joy of mind.
The room of the mind was filled with worry or fear．If you are free of thinking about them, the room has been emptied，and then you will see what is happening and experience it When your
mind stays quiet，you will see that happiness comes from the inside．

It is hard to predict（预言）how science is going to turn out, and whether it is really good science, it is impossible to predict．If the things to be found are actually new, they must be unknown in advance．You cannot make choices on this matter．You either have science or you don’t and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits．
The only solid piece of scientific truth about which I feel totally confident is that we don’t know enough about nature．Indeed, I regard this as the major discovery of the past hundred years of biology．It is, in its way, a clear piece of news．It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange the way ahead seems．In earlier times, they either pretended to understand how things worked or simply made up stories to give answers．Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered．Because of this, we are sorry．It is not so bad being ignorant（无知的）if you are totally ignorant; the hard thing is knowing in some details the reality of ignorance, the worst spots and here and there the not so bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted．
But we are making a beginning, and there ought to be some satisfaction．There are probably no questions we can think up that can’t be answered, sooner or later．Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, and pay attention．
51．Acoording to the writer, really good science________．
A．would surprise the brightest minds of the 18th  century．
B．will help people to make the right choice in advance
C．will produce results which cannot be predicted
D．will bring about disturbing results
52．It can be inferred from the passage that scientists of the 18th century________．
A．thought that they knew a great deal and could deal with most problems of science．
B．knew that they were ignorant and wanted to know more about nature
C．were afraid of facing up to the realities of scientific research
D．did more harm than good in man’s understanding of nature
53．Which of the following is NOT mentioned about scientists in earlier times?
A．They falsely declared to know all about nature．
B．They did not believe in results from scientific observation．
C．They paid little attention to the problems they didn’t understand．
D．They invented false rules to explain things they didn’t understand．
54．What is the writer’s attitude towards science?
A．He is sorry because of the ignorance of scientists．
B．He is delighted because of the latest scientific findings．
C．He is doubtful because of the great difficulties in scientific research．
D．He is confident though he knows well the great difficulties in scientific research．
55．The writer believes that sooner or later________．
A．man can’t deal with all the problems he can find because of the limits of human knowledge．
B．man can find solutions to whatever questions concerning nature he can think up
C．questions concerning nature are outsiede the field of scientific research
D．man can think up all the questions and answer them all．

It’s hardly surprising that weather is a favorite topic for so many people around the world---it affects where we choose to live, what we wear, our moods, and perhaps even our national characteristics．Studies have shown that changeable weather can make it difficult to concentrate, cloudy skies slow down reaction, and high humidity with hot, dry winds makes many people bad-tempered．
If you live in a place like Britain, where the weather seems to change daily if not hourly, you could be forgiven for thinking that the weather is random．In fact, the weather is controlled by systems which move around areas of the globe．In the UK the weather depends on depressions, often called lows, and anticyclones, also known as highs．These systems start in the Atlantic Ocean, and make their way across the British Isles from the west to the east．Highs bring sunny weather, while lows bring rain and wind．In modern times, human activities seem to be altering weather patterns．Gases produced by heavy industry change the temperature of the Earth’s surface, and affect cloud formation．Some researchers say that factories in Europe and North America may have been one of the causes of the droughts in Africa in the 1980s．
The human race has always tried to guess the weather, especially in areas of the world where there are frequent changes．Traditional rhymes point to early attempts to identify weather patterns, popular poems include:
Red sky at night, shepherds’ delight; red sky in the morning, shepherds’ warning．
Flies will swarm before a storm．
Rain before 7, clear by 11．
While folk wisdom can still provide a guide to help forecast weather, today’s methods of prediction increasingly rely on technology．Satellites, balloons, ships, aircrafts and weather centers with sensitive monitoring equipment, send data to computers．The data is then processed, and the weather is predicted．However, even this system cannot predict weather for longer than about a week．
66．When weather keeps changing, _____________．
A．people become bad-tempered
B．people’s reaction slows down
C．people find it hard to focus on their work

69．According to a traditional rhyme, if there is a red sky at night, the next day will be _______．
A．windy      B．rainy C．fine   D．snowy
70．Which of the following statements is true?
A．Anticyclones often bring rain and wind．
B．Weather forecasting has been done for a long time．

It is the season for long lines and frayed (紧张的) nerves. Here’s how to deal.

Lighten up

Do youreslf a favor and ship(运送) your presents. Nearly every U.S. airline charges a fee to check a bag, so shipping gifts is now cheaper and more convenient than carrying them in your luggage.

Weigh your options

Now knowing what you’re going to pay for your luggage is annoying. So calculate your overweight-luggage fees at home. You can find the fees out in advance by visiting new site Luggage Limits, which provides the latest information on more than 90 airlines.

Leave amateurs（不熟练者） in the dust

Trust us and get to the airport an extra half-hour early. The check-in and security lines are filled with inexperienced fliers, and it’s a hard walking. Plus, if you decide to cut it close, you may not get onto the flight at all. To reduce costs, airlines have reduced on flights and routes. The remaining flights are more likely to be oversold, especially on busy travel days. Fliers who check in early are the least likely to get bumped from oversold flights.

Take it public

The rates for renting a car at the airport have more than doubled over the past year because rental lot inventories(地产) have increased dramatically. True, renting at the airport is convenient, but it’s just not worth it anymore. Unless you really need a car, take public transportation, hop a cab, or beg a friend to pick you up at the airport instead.

Say no to bumper cars

Tell the people picking you up to avoid parking their car. They can hang out in their car for free while waiting to get a call from you when you land. Many airports, including JFK and LAX, now feature this sensible choice.

68.Airlines have reduced flights to_________.

A. deal with crisis                         B. reduce the time for leave

C. lower the cost                          D. provide more job chances

69. We can learn from the passage that____      .

A. taking a taxi at the airport is expensive

B. taxis stay at the airport free of charge

C. cars can park at the airport for free

D. JFK encourages people to take a taxi

70. What’s the best title for the passage?

A. 5 Ways to Survey a Holiday Flight.             B. Good Seasons for Flight

C. Cars at the Airport                     D. How to Board a Flight
