The porter brings your bags to your room and helpfully explains all you want to know．Then he points to the phone and says：“If there’s anything else you need, just can．”All this time you have been thinking of one thing：“How much should I tip(付小费)him?”To make your next trip a little easier, here’s guide to tipping across some Asian countries.
Bangkok
In general, the more westernized the place is, the more likely you will be expected to leave a tip．Some top-end restaurants will add a 10％ service charge to the bill．If not, waiters will appreciate your tacking on(附加)the 10％ yourself．However, if you’re eating at a lower-end restaurant, a tip is not necessary．If you’re staying at one of Bangkok’s many five-star hotels, expect to tip the porter 20 to 50 baht(泰国货币单位),depending on how many bags you have．Taxis are now metered in Bangkok．Local custom is to round up(凑整数)the fare to the nearest five baht．
Hong Kong
Tipping is customary in this money-mad metropolis(大都市)．Most restaurants add a 10％ service charge to the bill, but the extra money often ends up in the pocket of the owner. If the service is good, add another 10％ to the bill, up to HKMYMl00 in an especially nice restaurant．For HK MYM10 hotel porters should do it at all but the nicest hotels where a new HKMYM20 bill may be more acceptable．When in a taxi, round up to the nearest dollar．
Kuala Lumpur
Tipping in Malaysia is limited to the expensive westernized hotels, which often add a 10％ service charge to your meal or hotel room．If you are at a hotel restaurant, expect a 10％ service charge．
But at local restaurants, there’s no need to add a tip. At five-star hotels, one or two ringgit(马来西亚货币单位)will satisfy a porter. At lower-end buildings don’t feel you have to tip Like Bangkok, many taxis are now metered so you can just round up to the nearest ringgit．
Seoul
Tipping is not part of Korean culture, although it has become a matter of course in international hotels where a 10％ service charge is often added．If you’re at a Korean barbecue joint(烧烤处),there’s no need to add anything extra．But a nice Italian restaurant may require a 10％ contribution．
If you’re at a top-end hotel, so expect to pay 500～l,000 won per bag．Taxi drivers don’t accept a tip．Keep the change for yourself．
( )57．Which of the following is NOT the unit of money?．

Heading out for some exercise? You’ll take your shoes, socks, and a towel．You might take a music headset．But you’ll also need a bottle of water．Here is why．When you exercise, you sweat. Sweating is your body’s way of cooling down．The more you sweat, the more water your body loses．However, exercise also reduces thirst If you’re not thirsty, you may not drink enough water．You could lose too much water and become dehydrated(脱水)．A water loss of 10 percent can make you sick．A loss of 20 percent can kill you. So you need to be careful．
Here’s how to keep your body hydrated．About two hours before you exercise, drink one 500millilitre(1/2litre)bottle of water．Then drink another half bottle right before you begin．Drink water every 20 minutes as you exercise．You’ll need water long before you’re thirsty．
You need water even when you’re not exercising．You should drink about five bottles of water each day．Why so much? Your body cells are mostly water．So is your blood. Water helps your body to digest(消化)food and remove wastes．But your body loses water as you breathe, sweat, and urinate(排尿)．It loses about 2.5 liters (2,500 milliliters)of water each day．
You must replace the water your body loses．You can get water from many sources．Drinking water is the best source．Food and other fluids are good too, All food has some water in it．Fruit and vegetables are high in water Milk, juices, and other drinks also contain water．So take your pick．And remember to drink more water when you exercise．A happy body is a hydrated body．

A．about 2,500 milliliters of waterB．about 500 milliliters of water
C．as much water as you can D．only when you get thirsty
( )54．What are some ways to replace water your body has lost?
A．Taking baths and eating eggs．
B．Drinking juice and eating vegetables
C．Digesting food and removing wastes．
D．Eating many kinds of food and exercising．
( )55．After reading the whole passage, we learn it is mainly about．
A．the results of research on dehydration
B．water being important when we exercise
C．the importance of having enough water
D．how much water our bodies lose ever day
( )56．The author explains how to keep your body hydrated during exercise by presenting .
A．some related numbers B．the reasons why we need water

A few months ago, I had the responsibility of delivering some donations (捐赠物) to the local City Mission, a place where the homeless, and often the injured can find shelter from a life that has been turned upside down for them.
It was late autumn, and already the promise of winter was whispering through the open windows of the Mission's storage area.
After setting the donations near the sorting table, I said goodbye to the worker, and headed back through the dining area towards the door.
I was careful not to notice the people sitting at the tables, choosing to leave before feeling the guilt (罪过) of my " having", in the midst of so many who have nothing.
But it was not to be.
"Not yet," I heard a woman's voice say. "Not till we pray (祈祷)."
I was behind them when the mother bowed her head and began one of the most heartfelt prayers I have ever heard, and I stopped where I was to look over at the table. A young mother was there with her two young boys, one about three years old on her left, the other, about five, on her right. Both were waiting, heads bowed, eyes closed.
My heart broke as I watched and listened. She was in a leg cast (腿上打着石膏), and scars (伤疤) covered her arms, her face and head.
One of the younger ladies working at the Mission had come to stand beside me, and she whispered, "She's a single mom; her husband just took off one day and didn't come back. She came here when their apartment caught fire. She was burned getting her kids out."
She started to say something else but stopped.
We were silent ... and the words this young mother said in our silence will always follow me, "... and thanks for the fruit on the ground, when I just can't reach the tree."

A. happy to find the fallen fruit on the ground
B. regretful for not climbing the tree for the fruit
C. satisfied to pick up the fruit for her children
D. grateful very much for the help she received

The brain of an insect isn’t very big. But insects are somehow still able to make lots of important decisions. Bees, ants and roaches(蟑螂) build hives with thousands of workers doing specialized work. The jobs are done without a head or even a plan. How do insects manage this?
To solve the mystery, scientists in Belgium spent months building robotic roaches and then putting them among real roaches. The final goal of the research is to find out how the simple behavior of individuals gives rise to a collective(集体的) decision. The roach is a good starting point for trying to answer the big question because its social system is simple enough for scientists to study.
The first step was to build robots that real roaches would accept as their own. Although the robotic roaches don’t look much like the real thing, they have similarities with them in three key ways: they naturally head toward dark areas, they are influenced by the behavior of other roaches, and even more importantly, they smell like roaches.
The next step was getting the robotic and real roaches to work together on common tasks. In experiments, the robots would collectively head towards a dark place, copying the behavior of natural roaches. That got the researchers wondering: if you program the robotic roaches to go toward the lighted place, will the real roaches follow, going against their natural instincts.(本能) ?
They will – it turned out. Many of the real roaches followed the robots to a lighter shelter. But influence turned out to be a two- way street. On occasion, the real roaches were able to override the programming of the robot roaches and get them to turn into dark hiding places. Being social creatures, both the robotic and natural roaches were paying attention to and following the example set by others.
In theory, it would be possible to create a robot that could influence collective decision-making in humans. To do this, researchers would have to invent a robot that people would accept. Fortunately, the technology isn’t there yet.
69. Why do scientists choose the roaches to study?
A. Their social system is simple
B. They are social creatures.
C. They are able to build their hives quite well.
D. It is easy to create robotic ones.
70. The robotic roaches are accepted by real ones because of all the following EXCEPT that ______ .
A. they smell like real ones B. they look exactly like real ones
C. what they do are somewhat influenced by other roaches
D. they naturally head toward dark areas
71. What’s the author’s attitude to creating a robot that would influence collective decision-making in humans?
A. Uninterested B. Positive
C. Negative D. Doubtful
72. Which of the following might be the best title of the passage ?
A. Scientists’ Research B. Robotic Roaches
C. Amazing Insects D. Insects’ Social System
