[1]It's safe, it's simple, and it works: Drinking right amounts of water really can help you lose weight, new research shows．

[2]In what researchers claim is the first-ever trial of the effect of water consumption on weight loss, scientists from Virginia Tech found that dieters who started each meal with two glasses of water lost nearly five pounds more, on average, than dieters who did not, over the course of 12 weeks．There's no shortage of clear evidence about how water might work to control your appetite（食欲）．It ________________ so you don't eat so much; it keeps down your thirst so that you don't turn to calorie－rich sodas or juices．But until now, the researchers say, there has been no true evidence that water's appetite-controlling benefits ever translate into actual weight loss．Now there is． In the 12-week study period, dieters instructed to drink water with every meal lost an average of 15.5 pounds; dieters given no instructions lost, on average, just 11 pounds．

[3]Perhaps the most surprising thing about the finding is how little we still know about healthy water consumption in general．In fact, although doctors and public health authorities regularly remind us to drink more water, very few studies give any insight into what our ideal quantity may be．

[4]The new results today suggest that many people could indeed stand to drink a little more water than they do．But if you're looking to lose weight, be aware that it is actually possible to drink too much water, and you probably won't help matters any by drinking too much water at a time．In extreme cases, it can even be deadly．A couple of glasses with each meal, however, should be no problem at all for a healthy person．

It's time to remind myself what I love about life here in California,USA, to remember what I desperately miss when I go home.

Real radio

In the USA there are so many radio stations that those iPod tuner things don’t work at all. There is, simply, no dead air. It took me a while to discover the USA's many pub­lic radio stations, which don't broadcast any advertisements. KCRW is my favorites station, for its blend of indie music and current affairs. But I also listen to KJAZZ and KPCC. But before you feel jealous — it’s all online. My favorites: American life Snap Judgement and Henry Rollins live every Saturday night. Take listen online for free News? Well, there's not a lot of news from South Africa, and when it is, it's bad and full of fear, so I ignore it. But I care about any place I live in, and that includes the USA. And on public radio, the USA is covered in depth, from the perspective of individual stories rather than statistics.

The festivals

I’m jealously watching tweets and Facebook boasts and reviews from SXSW — seems like half the people I used to work with in South Africa are there,meeting Grumpy Cat and watching bands they’ve always wanted to see live. It’s great to know that these 1000s of festivals are so close, and that one day,if film school schedule ever allows me to leave campus for more than a few days, I can go to one or two of them. I have already ex­changed my much loved Ford Mustang for a bigger, less sexy car — a car spacious enough to sleep in — so that next year I can be there, not just dream of it.

The famous people

When I go back to SA, I'm often asked if I’ve spotted any famous people. It's awkward for me. I feel the the same way about it as I feel when an American asks me if there are lions in the streets. Except yes, I have. No,not lions. I have met some famous people. I chatted to RJ Mitte from Breaking Bad outside a dub in West Hollywood. Many of my professors are famous directors. The problem is, once you meet these famous people, they're just people, FFS. This feels disappointing at first, like you're missing a Jesus mo­ment of some sort. But if you think about it, it's inspiring. What it means, is that I, litlle me (right now, also "just a person") could be a famous just-a-person person one day, and get to make all the films I just dream of now.

1.The underlined sentence "There is,simply, no dead air." probably means____.

A. there is no useless radio programmes in the USA

B. there is no useful radio programmes in the USA

C. there is no polluted air in the USA

D. there is no advertisements from the radio programmes in the USA

2.There are so many festivals that_____.

A. I often leave campus for more than few days

B. I often attend some of them in person

C. I bought a bigger Ford? Mustang

D. I can share many reviews and performances online with my friends in South Africa

3.The author thinks the famous people in the USA _____.

A. are just Like lions????????????? ???????????? B. are well-known but ordinary

C. are disappointing????????????? D. are inspiring

4.The author is most likely to be _____.

A. a director in America????????????? ?????????? B. a professor in South Africa

C. a student in America????????????? ???????? D. an actor in South Africa

閱讀理解。
     When I was seven, my father gave me a Timex, my first watch. I loved it, wore it for years, and haven't
had another one since it stopped ticking a decade ago. Why? Because I don't need one. I have a mobile phone
and I'm always near someone with an iPod or something like that. All these devices (裝置) tell the time-which
is why, if you look around, you'll see lots of empty wrists; sales of watches to young adults have been going
down since 2007.
     But while the wise have realized that they don't need them, others-apparently including some distinguished
men of our time-are spending total fortunes on them. Brands such as Rolex, Patek Philippe and Breitling
command shocking prices, up to ￡250.000 for a piece.
     This is ridiculous. Expensive cars go faster than cheap cars. Expensive clothes hang better than cheap
clothes. But these days all watches tell the time as well as all other watches. Expensive watches come with
extra functions-but who needs them? How often do you dive to 300 metres into the sea or need to find your
direction in the area around the South Pole? So why pay that much of five years' school fees for watches
that allow you to do these things?
     If justice were done, the Swiss watch industry should have closed down when the Japanese discovered
how to make accurate watches for a five-pound note. Instead the Swiss reinvented the watch, with the aid
of millions of pounds' worth of advertising, as a message about the man wearing it. Rolexes are for those
who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family;
a Breitling suggests you like to pilot planes across the world.
     Watches are now classified as "investments" (投資). A 1994 Philippe recently sold for nearly ￡350, 000,
while 1960s Rolexes have gone from 15, 000 to 30, 000 plus in a year. But a watch is not an investment. It's
a toy for self-satisfaction, a matter of fashion. Prices may keep going up-they've been rising for 15 years.
But when fashion moves on, the owner of that? ￡350, 000 beauty will suddenly find his pride and joy is no
more a good investment than my childhood Times.
1. The sales of watches to young people have fallen because they _____.
A. have other devices to tell the time
B. think watches too expensive
C. prefer to wear an iPod
D. have no sense of time
2. It seems ridiculous to the writer that _____.
A. people dive 300 metres into the sea
B. expensive clothes sell better than cheap ones
C. cheap cars don't run as fast as expensive ones
D. expensive watches with unnecessary functions still sell
3. What can be learnt about Swiss watch industry from the passage?
A. It targets rich people as its potential customers.
B. It's hard for the industry to beat its competitors.
C. It wastes a huge amount of money in advertising.
D. It's easy for the industry to reinvent cheap watches.
4. Which would be the best title for the passage?
A. Timex or Rolex?
B. My Childhood Timex.
C. Watches? Not for Me!
D. Watches-a Valuable Collection.

        Most of my earliest childhood memories are of the beach-in the hot sun, building sandcastles,
burying Dad in the sandNow the coast has a pleasant and relaxing attraction beyond words. I looked
forward to a windy cliff-top walk or a rainy day rock-picking just as much as those rare moments when
Iget to a short sleep in the sun. But there's nothing more pleasurable than turning up at a beach to find it
deserted.
      These are my favourite secret beaches-ones either not well known or take a bit of effort to get to.
Most of those listed scored highly in the Marine Conservation Society Good Beach Guide 2009; the
others are too secret even for them.
     Sennen Clove is just a mile northeast of Land's End, the westernmost point of mainland England. It's
a beautiful spot, with white sands, deep green sea and amazing sunsets over the Isles(群島) of Scilly, 28
miles away.
     The west-facing beach is popular with surfers, with bigger waves and winds often found at the Gwenver end. There's a beach restaurant with good views of the bay and the sunsets.
     The smallest of Isles of Scilly, Bryher is a mile long, half a mile wide-and a natural wilderness of
unbelievable scenery. Walk along the narrow sandy roads to the eastern seaboard and you come to
two quiet beaches.
     Green Bay has views over to the palm trees of Tresco's Abbey Gardens, and a little further south is
Rushy Bay, a beautiful beach facing the deserted island of Samson.
     On Bryher, farm shops sell locally grown produce, and they trust you to leave the money in the pot.
It's that kind of place.
1. The best title for this passage is ________. 
A. The Beautiful British Isles
B. Secret Beaches on the British Isles
C. The Most Pleasurable Place in Britain
D. My Experience of Searching Beaches
2. According to the passage, which of the following is TRUE? _______ 
A. The author is a tourist guide in a tourist agency
B. The author likes walking on a rainy cliff-top most
C. The author wrote the article to advertise for the beaches
D. the author loves beaches that are not known to most people
3. Which of the following maps can correctly describe the geography position? ________
   (LE=Land's End    SC=Sennen CoveIS=the Isles of Scilly)
4. In author's view, farmers on Bryher are ________.
A. mean
B. selfish
C. sincere
D. lazy
