Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids: the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.
The people who built the pyramids made lots of secret doors and rooms to stop robbers from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing.
In AD 820, an Arab king named Abdullah AL Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms --- the Queen’s Chamber, the Grand Gallery and the King’s Chamber. But to their surprise, the men didn’t find the treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had someone already taken them away? The huge stone doors at the pyramid’s entrance were still closed when AL Manum’s men went inside. How had the thieves got in and out?
Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.
In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door.The first two paragraphs were written to show that ________.

| B．It is the only one of the ancient wonders that is still standing. |
| C．Abdullah AL Manum took the King’s mummy and his treasures away. |

On June 15th，2012，millions of people watched as 33yearold Nik Wallenda walked across one of the world's greatest waterfalls on a tightrope(钢丝)．What made the 25－minute walk that was televised live and watched by over 13 million people worldwide even more amazing，is that it was done over the Niagara Falls－An action that had never been attempted before.
Even though Nik was wearing a harness(保护带)，a safety measure provided by ABC，the television network that broadcast the event，his action to keep his balance against the strong winds made for some heart－stopping(令人担忧的) moments for the audience.
Nik，however，never slowed down for even one moment.Wearing special shoes made by his mother，he remained totally focused on the job at hand.It was only when he got to the last stretch near Canada's Table Rock that he knelt down on one knee and finally broke into a smile.Waving and blowing kisses to the cheering audience，he knew he had accomplished a great task，which most people had thought impossible.
While he described the whole experience as peaceful and relaxing，Nik said his biggest challenges came from a totally unexpected source－his 40 pound balancing pole.The balancing pole was so heavy that he could hardly carry it on the tightrope.
One would think that now that Nik has realized his lifelong dream he would be ready to hang up his “balancing pole”．However，the adventurer who already has seven Guinness World Records under his belt，is just getting started－Next up? A 5，000－foot tightrope walk across the Grand Canyon.While the one across the Niagara Falls took years of planning because he had to convince the US and Canadian officials，this one should happen in the very near future.That's because，the Florida resident has already been granted(授予) a permit by the Canyon officials.Why did so many people fix their attention on the event?
A．Because it was done by Nik Wallenda.
B．Because nobody had done it there before.
C．Because it was broadcast live by ABC.
D．Because it was impossible to do the event.What made the audience hold their breath during Nik's performance?
| A．How Nik managed to cross the Niagara Falls with safety measure. |
| B．What Nik would do when he lost his balance on the tightrope. |
| C．How Nik kept his balance against the strong winds. |
| D．How long Nik will take to finish the event. |
What was the greatest difficulty for him to face in Nik view?
| A．The supplied tightrope. |
| B．The safety belt. |
| C．The balancing pole. |
| D．The audience's noise. |
What does the last paragraph mainly talk about?

| B．Nik's life dream is changing. |
| C．Permission of governments is important. |
| D．The Grand Canyon is a dream for Nik. |

Keeping pace with teachers is a fine way to study English.Teachers are experienced and their plans are systematic.But remember to work in a way that suits you.It's important to learn from past mistakes as well.Keep a notebook to make a record of the mistakes you make－it'll help you avoid making the same ones later.
The time of life may be hard，but you're not alone.You may be busy studying，but you can show your care by calling your friends or sending short messages.Don't let your friendships die.

Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week，she held her breath as the air became a charcoal grey haze(炭灰色的阴霾)．The 39yearold businesswoman has lived in Beijing for a decade，and this past month，she said，brought the worst air pollution she has ever seen.It gave her husband a cough and left her sevenyearold daughter housebound(足不出户)．“My husband as well as I is working here，so we have no choice，” she said.“But if we had a choice，we'd like to escape from Beijing.”
The extended heavy pollution over the last month，which caused punishment in return for a day last week－called the “airpocalypse” by internet users－ has largely changed the way that Chinese think about the country's air.On one day，pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO)．Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January，Beijing's air was worse than that of an airport smoking area.
The smog's(烟雾) most threatening aspect is its high concentration(浓度) of PM 2.5 － particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream，causing breathing infections，lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year，65% of them in Asia.Which conclusion can we draw from the first paragraph?
| A．Hu Li is living in Beijing. |
| B．Hu Li traveled to Tianjin for business. |
| C．The haze is harmful to people. |
| D．The pollution is the worst in Beijing's history. |
The haze affected people mainly in________．
| A．the way they traveled |
| B．the opinion about national air |
| C．the way they lived their life |
| D．the life style of internet |
From the passage we know high concentration of PM 2.5________．
| A．can lead to choke |
| B．can cause heart cancer |
| C．will damage children's development |

What's the best title for the passage?
| A．Hu Li's attitudes to Beijing's haze |
| B．The damages of Beijing's haze |
| C．WHO suggests improving Beijing's air |
| D．What caused air pollution in Beijing |
