题目内容

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．

1．The latest eruptions were in_______.

A．1925 B．1959 C．1995 D．1983

2．The pressure under the volcano can not be released because _______.

A．the plug looks like a cork in a bottle

B．the volcano hasn’t broken out for some time

C．the center of the volcano is blocked（堵塞）by lava

D．the temperature of the steam is not high enough.

A．has broken out three times

B．never dies but continues to be active

C．will kill many people again in the future

Breathe, wave and smile. Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping.

It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment—the commencement (graduation ceremony).

Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown.

Our principal, Mr. Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance(美国的爱国誓言).

Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, “Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever.”

Then came the core (the most important part) of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest.

To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn’t boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives.

A new page in the book of that person’s life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage.

What’s the article mainly about?

A. An American high school’s graduation ceremony.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

I live in Japan, where electronic items are a way of life, so it is no surprise that many students carry these little electronic dictionaries. E-dictionaries may be lighter and compacter (简洁的) than any paper dictionary. However, to me, these are pretty much the limits to their advantages.

I think e-dictionaries should be limited in their use in classrooms.

E-dictionaries are much more expensive. In Japan, they cost as little as 10,000 yen(US$100)much as 40,000 yen, depending on how many functions you want (or think you want) and depending on how fashionable you are. My trusty Random House paper dictionary is copyrighted at1995, cost me a mere US$12.95 plus tax.

E-dictionaries are more fragile. Drop your paper dictionary. Go ahead. Hold it above your head and drop it.

E-dictionaries need batteries. Batteries are temperature sensitive. Batteries cost money, too.

E-dictionaries have keypads. Typing in the spelling of a word is harder and more time consuming than looking through pages and using the index at the top of each page.

Sound . Little devices beep (嘟嘟声) when you press the buttons, but it is very disturbing to some people in a classroom situation or library.

Finally, let’s consider making corrections or additions. No dictionary is perfect, paper version or electronic. However, when you find something you’d like to change in the e-dictionary, you can’t do anything about it. You can pencil in some notes with the paper type. Similarly, if you learn a word that isn’t in the dictionary, a few notes of a pencil make it easy to increase its memory capacity. And, for those students whose habit is to mark certain words with a highlight pen for ease of future reference, again, the paper dictionary wins out.

A．But it is impossible to do so with a keypad model.

B．They may even contain more words and expressions.

C. Let me add a statement about one that really troubles me.

D．Now, try this with any lightweight plastic e-dictionary, and you’ll be picking up the pieces.

E．That huge, heavy paper dictionary that you see in your library looks like a building block in size and weight.

F．E-dictionaries have advantages as well as disadvantages.

G．Let’s take a look at the following reasons.

As the sound of footsteps behind her grew louder, she quickened her pace. She didn’t want to turn around as the memory of that morning’s newspaper headline made her afraid of what she would see: “City Killer Claims Fourth Victim.”
“Why did I stop for a few drinks in the bar after work?” she thought to herself. Now it was dark and the streets deserted. She was alone and a sitting duck.
She felt as if she was walking in the rain. Her clothes were damp from nervous sweat and as each short hot breath hit the night air, it turned to steam, coating her glasses in a thin film so all she saw seemed covered in fog.
The footsteps were closer now. She needed to get off this street. Her eyes began a useless search for an open store or lighted window. Passing a small lane she looked through，for a possible escape route. But the lane was a dead - end and she laughed to herself at the irony.
The sound of a car behind her turning onto the street interrupted her self – pity. Escape was at hand. But as she was about to throw herself onto the road and shout for the car to stop, the car’s headlights cast a shadow that paralyzed （使瘫痪） her with terror.
It was the footsteps’ owner. The figure was huge and in its raised arm it held what looked like a lead-pipe, no doubt the one that was about to claim victim number five.
The shadow dissolved as the car passed by and disappeared into the distance. She felt a hand on her shoulder. It was all happening as if in slow – motion. She was waiting for her life to flash before her eyes like all those novels said it would – but it didn’t. The only thing she thought of was her dear husband. She recalled phoning him from work that very afternoon and joking about, of all things, the city killer. It was a night full of ironies.
There was a voice talking to her now but she was lost in thoughts of her fate and didn’t respond. The hand then began turning her around. It was surprisingly gentle given what was about to come. She allowed it to guide her without resistance. （抵抗；反抗）
She looked up. She recognized the face, but she didn’t know from where. Its mouth was still talking to her but she couldn’t understand. Then she remembered. The face belonged to the foreign looking man who had served her at the bar. She looked down to his hand and saw in it not a lead – pipe but a rolled up copy of a work report she had been correcting in the bar as she drank.
His words suddenly started to register in her brain and she could hear him. “Miss, Miss. Are you OK? You left this in the bar and it looked important so I thought I’d better give it to you.”

C. The city of Machu Picchu in Peru includes some of the best stone work ever built. The ancient Inca people built Machu Picchu high in the Andes Mountains, northwest of the city of Cuzco. Machu Picchu is about thirteen square kilometers. Historians say it might have been one of the last places of safety for the Incas who were fleeing invaders from Spain.

D. India is famous for its temples and buildings. The most famous is the Taj Mahal, considered one of the most beautiful buildings ever built.
