The huge explosion at Krakatau was the result of two different factors. One was that the volcano had not broken out for some time and so at the very center of the volcano there was a huge plug of lava, which acted like a cork(塞子) in a bottle, stopping the pressure below from being released(释放). The second factor was that ocean water entered the very centre of the volcano as the explosions became more violent. This caused superheated steam to build up enormous pressure and this was finally released in the largest explosion of all on August 27, 1883. The sudden release of the pressure sent huge amounts of ash, rock and dust into the sky. Some of the ash rose 80km into the air and traveled around the Earth causing brightly coloured sunsets for several years.
Krakatau almost disappeared; for many years after this explosion, it remained very quiet. However, there was still activity going on under the sea and on 25 January, 1925, a small volcanic cone appeared above the surface of the water. This new volcano was named Anak Kmkatau, or Child of Krakatau. Over the following years, the size of the island grew larger, by 1959, the island was 300 metres above the surface of the sea. The volcanic activity has continued and the latest eruptions were in 1995.
There is no doubt Krakatau will continue to grow and there is also strong evidence that at some point in the future there will be another violent explosion. Krakatau is in a part of the world where the surface of the Earth is unstable and is always moving and cracking. If, in the future, another “cork” becomes fixed in the centre of the volcano, the pressure will build up. A series of a smaller explosions will allow sea-water into the centre of the volcano and once again the result will be a terribly destructive explosion.

When I was small and my grandmother died, I couldn’t understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying.
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying.
Whatever it takes for us to reduce pressure is important to our emotional (情感的) health, and crying seems to work well. One study found that 85 percent of women and 73 percent of men report feeling better after crying.
Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and more friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we' re very sad until we cry. We learn about our emotions through crying, and then we can deal with them.
Just as crying can be healthy, not crying — holding back tears of anger, pain or suffering — can be bad for physical health. Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural — and healthy — emotional response.
1.People can do benefit from crying except_______?
A. reduce pressure

A. Because her father did not want her to feel too sad.

D. The author doesn’t give the reason.
3.It can be inferred from the text that ______.
A. there are two ways to keep healthy
B. crying does more good to health than laughing
C. crying and laughing play the same roles
D. emotional health has a close relationship to physical health
4.According to the author, which of the following statements is true?
A. Crying is the best way to get help from others.
B. Fighting back tears may cause some health problems.
C. We will never know our deep feelings unless we cry.
D. We must cry if we want to reduce pressure.
5.What might be the most suitable title for the text?
A. Power of Tears B. How to Keep Healthy
C. Why We Cry D. A New Scientific Discovery
In the southern part of America, when somebody has a birthday, often family or friends, or both, will arrange a party. The party could be elaborate(精心准备的)and include a meal or may be simple with a birthday cake and drinks. One does not plan, nor give, one’s own birthday as is the custom in some cultures. At a party there is usually a decorated cake, often with the words “Happy Birthday” and with the name of the person written on the top of the cake. Sometimes there is also one candle for each year of the person celebrating the birthday before the cake is cut. While blowing out the candles, the person makes a wish for something pleasant.
Usually those invited to a birthday party will bring a gift for the person honored. Gifts given by friends do not have to be expensive, but the family of the birthday person will spend whatever they can afford on a gift.
Christmas parties also are very popular in the South. Often this is the only time during the year that some people see acquaintances(熟人). These parties can be elaborate or simple, ranging from a buffet(自助餐)to a reception called “open house (家庭招待会)”. If you are invited to one of these, you don’t need to take a Christmas gift, as it is not customary to take the hostess a gift every time you are invited to a party or a meal. However, if you wish to take a gift, it should only be something useful and inexpensive and should be given to the hostess at the door as you enter the party. Usually gifts of Christmas food treats are the most appreciated.
