1 . The body gives off many gases. Although some smells may signal a need to bathe or that you ate a certain meal, other gases might point to serious disease. Now, researchers have come up with a system that uses earmuffs to catch the disease-signaling gases. Doctors could get the information as patients wear a set of earmuffs. Results could be ready within minutes.

“The ear is a good place to monitor,” explains Johnson, a biomedical engineer. The ear’s skin is fairly thin, he notes. So gases don’t have to travel far to get out of the blood and escape through skin pores.

To collect the gases, Johnson and his team selected earmuffs that make a tight seal with the head. These are the type people often wear to protect the ears from loud noise. His team made two holes in the muff covering one ear. A tube slowly pumped air in one hole. Another tube pulled air out of the second hole and sent it to a sensor.

In their tests, the team found that they could measure changes in the amount of alcohol coming from the skin of the ear. It could work much like a Breathalyzer that police use to test people for driving drunk. The team invited three men. Each had to avoid drinking alcohol for at least three days before taking part. Once in the lab, these men wore the earmuffs and sat for 10 minutes as the system recorded normal gas levels leaving their ears. Afterward, the men drank a big amount of alcohol. About 7 minutes later, the earmuff system tested out a rise in alcohol leaving the skin. After 50 minutes, alcohol levels reached the peak and continued falling until the test was over.

The team then measured other gases by changing out the sensor. With the right sensor, their earmuff system could test out disease. Later, they replaced the earmuffs with a one-eared version to make it a bit more comfortable.

Johnson imagines another possible benefit. The earmuff system could help doctors tell whether a child’s ear infections have been caused by bacteria or a virus. How? Each type of infection exudes different gases. That, in turn, could guide how doctors cure the disease.

2 . Wang Yaping’s dream of becoming an astronaut was inspired by Yang Liwei’s 2003 space flight, which was China’s first manned space mission.

Born in a small village in Yantai, Shandong Province in 1980, Wang had been an enthusiastic long-distance runner since primary school, and competed in local sports meetings.

In 1997, Wang, a high school student, was encouraged to register for the pilot recruitment program by her classmates because she was good at sports and didn’t wear glasses. The 17-year-old had been considering applying to a teaching college, as her parents suggested.

Given her strong build and ability to stay calm under pressure, Wang passed all tests as well as physical examinations and became a female pilot in China. After four years of systemic education and tough training, Wang eventually learned to fly four different types of aircraft before graduation.

During her service as a military pilot, she accumulated 1,567 hours of flight time and was involved in major tasks such as the 2008 Wenchuan earthquake relief effort and the 2008 Summer Olympics in Beijing.

In May 2010, Wang became a member of China’s first batch of female astronauts. The joy of being selected did not last long as the hard training quickly sank in.

In the first year, Wang could not get the top level in the high-G training, during which she had to endure eight times the force of gravity in a spinning centrifuge. The training imitates the environment when the spacecraft takes off, enters orbit and returns. Wang improved her performance by doing extra core-strength exercises every day to strengthen her back and abdominal muscles. She got the top level at the end of 2011. Wang realized her space dream in 2013 as part of the Shenzhou-10 mission.

Over the past two years, Wang has logged in over 6,000 hours of strict training. The most tiring exercise was the seven-hour underwater training session during which she had to wear a special suit that weighed over 100 kilograms to simulate extravehicular activities in a weightless environment.

Wang has become the first female taikonaut to work in China’s Tiangong space station as well as the first Chinese woman to perform a spacewalk.

1. Why did Wang want to become an astronaut?

A．Because she was able to stay calm under pressure.

B．Because she was good at sports and didn’t wear glasses.

C．Because she was influenced by China’s first manned space flight.

D．Because she was advised to register for the pilot program by her parents.

2. From this passage, we can know that ________.

A．Wang won a long-distance runner championship

B．Wang was the first Chinese female to take a spacewalk

C．Wang went to a teaching college encouraged by her classmates

D．Wang thought the seven-hour underwater training session was easy

3. What did Wang do after she joined China’s first batch of female astronauts?

A．She learned to fly four different types of aircraft.

B．She participated in the Shenzhou-10 mission of China.

C．She received four years of systemic education in university.

D．She got involved in the 2008 Wenchuan earthquake relief effort.

4. Which of the following words can best describe Wang?

A．Calm and friendly.	B．Warm-hearted and creative.
C．Modest and honest.	D．Hardworking and determined.

3 . The television this morning was displaying some new adventure movie about the hunt for a treasure ship full of gold.     1     Most of main characters have the dream of becoming an overnight millionaire. Later in the day I was at the gas station in line to pay for a filling up my car when the guy in front of me traded a handful of cash for a handful of hope in the form of Lotto tickets.

Where did this desire for treasure come from? I know I myself am guilty of it. As a boy I would walk in the woods and daydream of finding buried treasure there. Then as an adult I would fantasize about some unknown relative leaving me a fortune or of my two self-published books becoming best sellers.     2     However, when I see all the rich and famous people on television I can see that they aren’t that happy and that they have their own unique set of problems.

    3     There really is a true treasure out there that will make our lives so much better and the most amazing thing of all is this treasure is absolutely free. This treasure is love. There is so much love around us and when we invite the love into our hearts and lives we become rich, our days are filled with smiles, and our lives are full of joy. When we have love inside us, the problems of this life lose their power over us.     4    

Then how shall we look for treasure? The true treasure of life is already inside of you.     5     And the funny thing is that the more you share it with others, the more of it you have within yourself. Embrace love for you then. Share it with the world. It is a treasure that does not decay or disappear. It is a treasure that lasts forever.

A．While our lives may not be perfect, we are happy.

B．You just need to open the chest and spend it like crazy.

C．It doesn’t necessarily mean we need to dig holes to find treasure.

D．Maybe the real problem is that we are all looking for the wrong treasure.

E．It reminded me of all the other movies just like it I had seen over the years.

F．Treasure is usually defined as gathered wealth in the form of money or jewels.

G．Perhaps we all just think that having a lot of money will solve all of our problems.
