Some people will do just about anything to save money.And I am one of them.Take my family's last vacation.It was my sixyearold son's winter break from schooland we were heading home from Fort Lauderdale after a weeklong trip.The flight was overbookedand Deltathe airline,offered us $400 per person in credits to give up our seats and leave the next day.I had meetings in New Yorkso I had to get back.But that didn't mean my husband and my son couldn't stay.I took my ninemonthold and took off for home.

The next day,my husband and son were offered more credits to take an even later flight.YesI encouraged—okay,ordered—them to wait it out at the airport to “earn” more Delta Dollars.Our total take$1,600.Not badhuh?

Now some people may think I'm a bad mother and not such a great wife either.But as a bigtime bargain hunter,I know the value of a dollar.And these daysa good deal is something few of us can afford to pass up.

I've made a living looking for the best deals and exposing(揭露) 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 TradeA 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 its shape longerand 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?

AThey took a later flight.

BThey had early bookings.

CTheir flight had been delayed.

DTheir flight had been cancelled.

2.What can we learn about the author?

Can people change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour.

The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.

Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment(色素) gene into a young fish. As with humans, zebrafish skin colour is determined by pigment cells, which contain melanosomes(黑色素). The number, size and darkness of melanosomes per pigment cell determines skin colour.

It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation(變異) in the gene for melanosome production. This results in less pigmented skin.

However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.

Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun(太陽光紫外線), which can cause skin cancer.

But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.

Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin colour, said Cheng.

The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treatment did on Michael Jackson.

The passage mainly tells us that ________.

  A. people can not change their skin colour without any pain

  B. the new discovery could lead to search into ways to change skin colour safely

  C. pop king Michael Jackson often changed his skin colour as he liked

  D. scientists have found out that people’s skin colour is determined by the gene

It can be inferred from the passage that ________.

  A. nowadays people who want to change their skin colour have to suffer a lot from the damage caused by the chemical  treatment

  B. Europeans and Africans have the same gene

  C. the new discovery could help to find medical treatments for skin cancer

  D. there are two kinds of genes

Scientists have done an experiment on a dark-striped zebra fish in order to ________.

  A. find the different genes of humans’

  B. prove the humans’ skin colour is determined by the pigment gene

  C. find out the reason why the Africans’ skin colour is dark

  D. find out the ways of changing peopl’s skin colour

The writer’s attitude towards the discovery is ________.

  A. neutral                      B. negative                   C. positive                    D. indifferent

閱讀理解
     That cold January night, I was growing sick of my life in San Francisco. There I was walking home 
at one in the morning after a tiring practice at the theater. With opening night only a week away, I was 
still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at 
night at the same time. 
     As I walked, I thought seriously about giving up both acting and San Francisco. City life had become 
too much for me. As I walked down empty streets under tall buildings, I felt very small and cold. I began 
running, both to keep warm and to keep away from any possible robbers. Very few people were still 
out except a few sad-looking homeless peopl e under blankets.
     About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to 
see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the 
noise had made me nervous, so I started to run faster. Not until I reached my apartment building and 
unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.
     Suddenly I wasn't cold or tired any more. I ran out of the door and back to where I'd heard the 
noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.
     Just as I was about to give up the search, I heard the garbage truck pull up to the sidewalk next to 
me. When a voice called from the inside , "Alisa Camacho?" I thought I was dreaming. How could this 
man know my name? The door opened, and out jumped a small red-haired man with an amused look 
in his eyes. "Is this what you're looking for?" he asked, holding up a small square shape.
     It was nearly 3 a.m. by the time I got into bed. I wouldn't get much sleep that night, but I had got my 
wallet back. I also had got back some enjoyment of city life. I realized that the city couldn't be a bad 
place as long as people were willing to help each other.
1.How did the writer feel when she was walking home after work?
A. Cold and sick                    
B. Lucky and hopeful
C. Satisfied and cheerful              
D. Disappointed and helpless
2.From the first paragraph, we learn that the writer was busy _____.
A. solving her problem at the bank      
B. getting used to the city life
C. learning acting in an evening school   
D. preparing for the first night show
3.On her way home the writer______.          
A. lost her wallet unknowingly
B. talked a lot with a garbage truck driver
C. was robbed of her wallet by a man with a knife  
D. found some homeless people following her
4.From the text, we can infer that the writer_____.
A. would stop working at night        
B. would stay on in San Francisco
C. would make friends with cleaners.   
D. would give up her job at the bank
