First, the amount of alcohol in 27 different popular energy drinks was measured. All but one had an alcohol level greater than 0.005%. In nine of the 27 drinks, the alcohol level was at least 0.096%.The scientists then investigated the possibility that these small levels of alcohol could be discovered by an ABT. They asked test subjects to drink a full can or bottle of an energy drink and then gave each subject an ABT one minute and 15 minutes after the drink was finished.
For 11 of the 27energy drinks, the ABT did find the presence of alcohol if the test was given within one minute after the drink was taken. However, alcohol could not be discovered for any of the drinks if the test was given 15 minutes after the drink was consumed. This shows that when the test is taken plays an important role in the test result. The sooner the test is conducted after the consumption of these drinks, the more likely a positive alcohol reading will be obtained.

Peng Liyuan has been wearing Ma Ke’s designs for more than a decade, a fact that was only highlighted recently when she was on her first state visit, accompanying her husband President Xi Jinping. The elegant and attractive Peng, formerly a popular singer, has been compared with the US’ first lady Michelle Obama and France’s Carla Bruni-Sarkozy, since stepping off the airplane in Moscow on March 22. Suddenly, everyone was curious to know more about the first lady’s wardrobe.
Even so, Ma prefers a low-key approach. “If you eat a tasty egg why would you want to see the hen?” she says of all the media attention.
Ma’s relationship with Peng began 10 years ago after a concert in Guangzhou when a reporter told Peng she knew the designer behind the label Exception de Mixmind. Peng asked for an introduction because she was a fan of Ma’s designs and had been wearing them for years.
The two naturally became friends. Ma says, “The painting reflects the painter, and clothes reflect both the designer and the wearer. Someone desires fame and wealth, or love and sympathy; what you have in your heart is reflected in the design. Those who don’t share my philosophy won’t buy my clothes. Peng is a caring person, devoted to charity and environmental protection, which is exactly what I’m doing now.”
However, regardless of the brand, Peng’s support of Chinese labels has surprised millions of Chinese who favor foreign fashion brands.
“Instead she presented a vision of Chinese fashion, desiring to bring Chinese designers to the world stage,” says a western designer.
The first lady’s double-breasted coat and her black leather handbag aren’t available at any of Exception’s shops, though Exception’s physical stores do have seen a rising number of visitors.

| A．it is hard to explain “Which came first, the egg or the hen?” |
| B．paying such great attention to her was unnecessary |
| C．the outcome was more important than the process |
| D．her dissatisfaction with the media attention on her dress |
| A．First ladies compete with each other whenever they are together. |
| B．Peng’s suits can be bought in Ma Ke’s clothes stores. |
| C．Ma Ke offered to design the first lady’s clothes through her friends. |
| D．Peng had liked Ma’s designs long before she got to know her in the flesh. |
| A．often reflects on what she has in her heart before choosing clothes |
| B．is sympathetic and has a strong environmental consciousness |
| C．always desires the exceptional charm of the brand |
| D．is knowledgeable in philosophy |
| A．Peng wears the dress designed by a Chinese designer probably to support Chinese brands. |
| B．Many citizens found Peng Liyuan’s choice quite unexpected. |
| C．Black leather handbags like Peng’s are widely sold in bag stores in big cities. |
| D．After Peng Liyuan’s visit to Moscow Ma Ke’s clothes became more popular. |
Zhang Youxia, commander-in-chief of China’s manned space program, said the Shenzhou X mission was a “complete success”.
The Shenzhou X landed safely in north China’s Inner Mongolia Autonomous Region at about 8:07 a.m. on June 26, 2013. All three astronauts were in good physical condition.
Nie Haisheng, commander of the Shenzhou X crew and a second-time space traveler, was the first to get out of the bowl-like module（舱）, followed by Wang Yaping, the only female astronaut of the mission, and Zhang Xiaoguang. During a brief welcoming ceremony held at the landing area, the astronauts waved happily to a crowd consisting of officers, the search and recovery team, and health personnel.
“It feels really good to be back home,” said astronaut Nie Haisheng.
“We are dreamers, and we have now realized our dream,” said Zhang Xiaoguang. “Our space dream knows no limit, and our hard work will never stop,” he said.
Compared with its previous mission Shenzhou IX last year, the Shenzhou X is no longer experimental but considered an applicable shuttle（航天飞机）system for sending astronauts and supplies to orbiting modules. The mission aims to further test technologies designed for docking（对接）and supporting astronauts’ stay in space, as well as to use new technologies related to the construction of a space station.
In its 15-day journey in space, Shenzhou X docked with the orbiting space lab Tiangong-1 twice, once through automatic operation and the other manual（手控的）.The Tiangong-1 space lab has been in orbit for more than 600 days. It’s designed to work for two years. The module is considered the first step in building a permanent space station in the future. And the astronauts spent 12 days in Tiangong-1, where they conducted space medical experiments, technical tests and gave a science lesson to students on Earth on June 19 about basic physics principles. The lecture was the second video class sent from space, with US astronaut Barbara Morgan’s 25-minute class being the first in 2007.
China is the third country after the United States and Russia to acquire the technologies and skills necessary for space rendezvous（交会）and docking procedures, as well as supply manpower and material for an orbiting module via different docking methods.
Previous docking procedures conducted between Shenzhou-type spacecraft and the orbiting space lab included two automated dockings by the unmanned Shenzhou-8 in 2011 and both an automated and manual docking by the manned Shenzhou-9 in 2012.
Since its first manned space space mission in 2003, China has sent ten astronauts and six spacecrafts into the space.

| A．learn how to make use of a manned space station |
| B．prove the importance of the manned space program |
| C．experiment on how to make astronauts stay in space safely |
| D．test new technologies for the construction of a space station |
| A．Nie Haisheng is the only male astronaut of the mission |
| B．The Tiangong-1 space lab was founded in 2012 |
| C．China is the second country to give a space class |
| D．the Tiangong-1 was mainly designed to serve Shenzhou X |
| A．China Prepares for Next Manned Mission |

“I stepped out and was flabbergasted,” local journalist Bahram Baloch told the BBC. “I could see this gray, dome-shaped (圆顶形的) body in the distance, like a giant whale swimming near the surface. Hundreds of people had gathered to watch it in disbelief.”
This island has become a global curiosity. How was it formed in just a few minutes?
As you might already know, many islands in the sea are formed by volcanoes. There are numerous volcanoes under the sea. As the hot lava erupts and cools down, it piles up and forms the shape of a mountain. When the mountain “grows” to higher than the sea level, the part that’s above the water is what we call an “island”.
This is how the island was formed after the Pakistan earthquake, except that instead of a regular volcano, it was a “mud volcano” that brought about this island. Lava is not the only thing that’s locked under the Earth’s crust — there is also gas. When an earthquake happens and breaks part of the crust, the gas is released at an extremely high speed, pushing mud up to the surface, according to National Geographic.
But only earthquakes that are extremely powerful can cause mud volcanoes to push up enough mud to produce islands — and this 7.7-magnitude earthquake in Pakistan was strong enough. The island is about 20 meters high, up to about 90 meters wide and 30 meters long, nearly the size of a soccer field.
In fact, mud volcano islands aren’t new. This is the fourth island of this kind in the region since 1945. But those islands usually didn’t last long.
“It will probably be gone within a couple of months,” said Bill Barnhart, a researcher with the US Geological Survey. After all, “it’s just a big pile of mud that was on the seafloor that got pushed up”.
小题1:What is the article mainly about?
| A．The disastrous effects of coastal earthquakes. |
| B．The difference between mud volcanoes and regular volcanoes. |
| C．How islands are formed by mud volcanoes. |
| D．The great natural wonders of Pakistan. |
| A．surprised | B．disappointed | C．worried | D．curious |
| A．the new island near the coast of Pakistan actually took a few months to form |
| B．scientists still know little about different types of volcanoes |
| C．another earthquake is likely to happen in Pakistan within a couple of months |
| D．not all volcanoes change the geological appearance of the Earth |
| A．are quite difficult to locate |
| B．usually disappear after a short period of time |
| C．are formed by hot lava from volcanoes |
| D．used to be part of the Earth’s crust |
The aim is to help teenagers keep their mind on their work by keeping males and females apart. Rebecca Brown chooses the students for what Boonsboro High School calls the Academy. “What we really want to do is take that top group of kids and take them to the very highest level they can achieve here，so that they’re prepared for college，” she said. They need high marks and test scores and strong teacher recommendations. They also need to be involved in activities.
Michael Bair has been at Boonsboro High School for twenty years and directs the Academy. His ninth－grade English class for boys centers on books that he believes boys find interesting. “The novels they’re reading now，are very manly novels. They’re novels that deal with the arrogance(傲慢)of man and the pride of man.” One of those books，for example，is “The Call of the Wild” by Jack London. This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada’s Klondike Gold Rush.
On this day，the students are working in small groups. Vincent and Logan explain why they’re drawing pictures that relate to the story. Vincent said，“The main character，Buck，gets abducted(绑架), and they send him off to the Yukon in a train. So I’m drawing part of the story where he’s in the train. It gets you to visualize the setting of the story and gets you to think more about what’s going on in the story，the important events of the story.”“ Instead of just doing work sheets about it，this is a lot more fun，” Logan added happily.
Morgan Van Fleet likes being in the Academy. She says boys and girls act differently when they are together in a classroom. “To me，it almost seems like it’s hindering(妨碍) your chances at developing yourself because you’re more focused on ‘Oh，I wish they’d shut up. Oh，what do they think of me？’ instead of focusing on what’s the homework or what’s going on in this class，what’s the lesson.”

| A．To educate. | B．To persuade. | C．To instruct. | D．To introduce. |
| A．any student in Boonsboro High School can take part in the program |
| B．students in the program are expected to get well prepared for college |

| B．Vincent thinks that his drawings can help understand the novel better. |
| C．Jack London is a main character in the book “The Call of the Wild”． |
