1 . Have you ever been in a bathroom, dressing room or another private area with a mirror and had that feeling that someone is watching you? You can check to see if a mirror is transparent by observing how it is installed and using a few simple techniques to determine if there’s a wall behind it.     1    

Check out the lighting. For a two-way mirror to be effective, the light on the mirrored side needs to be 10 times brighter than the light on the other side. If the lighting is dimmer, it’s possible to see through the glass to the observation area. Look around and determine whether the lighting seems extraordinarily bright.     2    

    3    Press your face up to the mirror and cup your hands around it, creating a dark tunnel to block out as much light as possible. When you do this, if the light in the observation room is at all brighter than the light on your side of the mirror, you should be able to see something through the glass.

Sound it out. The sound of tapping a two-way mirror has also been described as bright or sharp as opposed to a thud (砰的一声) from an everyday mirror. Tap on the surface of the mirror with your knuckle (指节).     4    An observation mirror will produce an open, hollow and echoing sound because there is an open space on the other side.

    5    Then hold a flashlight to the mirror (it can be the “flashlight” on your smartphone). If it is a two-way mirror, the room on the other side will be illuminated and you’ll be able to see it.

A．Turn off the lights.

B．Try to look through the glass.

C．Observe how the mirror is installed.

D．If so, you might be looking at a two-way mirror.

E．There are some accurate ways to tell if a mirror is two-way or not.

F．A normal mirror will produce a dull, flat sound, since it’s placed in front of a wall.

G．People standing on the other side of the wall can observe someone looking in the mirror.

2 . The Myers-Briggs Type Indicator (MBTI) was invented by Katharine Cook Briggs and her daughter Isabel Briggs Myers. It is a self-report questionnaire indicating differing psychological preferences in how people perceive the world and make decisions. The MBTI personality inventory (量表) sorts people into 16 type categories, each of which is represented by four-letter codes such as INFP and ESTJ. Every year, about 1.5 million people have enjoyed discovering their personality type by completing the MBTI. Many companies, as well as hundreds of universities, use it in hiring and training.

Nevertheless, the MBTI has received a noticeable criticism from the academic community. Some research suggests the MBTI is unreliable because the same person can get different results when retaking the test. Other studies have questioned the validity of the MBTI, which is the ability of the test to accurately link the “types” to outcomes in the real world -for example, how well people classified as a certain type will perform in a given job.

Merve Emre, a professor a Oxford University, points out that it would be more scientifically advisable to score the MBTI scales continuously to show people the degree to which they resemble the types. Even when the MBTI’s results don’t quite match your intuition (直觉) about yourself or are just wrong, they can still provide self-insight and insight into differences and similarities between people.

Scoring and interpreting the MBTI the way other personality inventories are scored and interpreted might be less fun than finding. All of the folklore (民间看法) about INFPs, ESTJs, etc. would have to be dismissed. But, in the end the MBTI is sufficiently reliable and valid enough to be useful in a number of real-world contexts.

3 . At most schools in the U. S., it’s customary to have a cheer squad (啦啦队) to support athletics. Cheerleaders drum up excitement before games, put on jaw—dropping routines at games, and provide support on the sidelines of most events. But students who participate in performing and visual arts seldom receive the same displays of support as athletes do. A group of students at Mountain View High School in Orem, Utah, decided to change that fact by creating a cheer squad just for the arts.

Their school’s athletics cheer squad is called the Bruin Crazies, so they named their artistic cheer squad the Bruin Classies! This is a new brand with which they could create something for all of the arts, whether it is band, dance show, photography and art galleries—to give them some publicity and cheer them on.

Classies wear a “uniform” of bow ties to indicate the “sense of class”artistic efforts bring their school. They carry around signs to advertise the upcoming play, musical, or dance performance. Hoping to drum up ticket sales, they encourage their fellow students to come out to support the hard work of others. They also attend performances and displays at school to cheer their classmates on.

After years of discussion to make a cheer squad for the arts, this is the first time they’ve been able to pull it off. More than 90 students have already signed up to be a Bruin Classy! “The students have poured their time and energy into their arts, and it is worthy to be celebrated. ”Caleb Stay, the cheer squad leader, said, “If you worked really hard on something and no one showed up, it would be disappointing. We just want to make sure that no one feels that way. ”

This is such an amazing idea! We can’t believe no one has come up with it before, but hopefully these thoughtful teens have started a new trend to support the arts in other schools, too.

4 . The discovery of the ruined palace in the Mosul Dam reservoir on the banks of the Tigris River inspired an archeological dig that would improve understanding of the Mittani Empire, one of the least-researched empires of the ancient Near East, a team of German researchers said. “The find is one of the most important archeological discoveries in the region in recent decades,” Kurdish archeologist(考古学家) Hasan Qasim said.

The palace would have originally stood just 65 feet from the river on a terrace(梯田). A terrace wall of mud bricks was later added to make the building stable. Ivana Puljiz, an archeologist from the University of Tübingen’s Institute for Ancient Near Eastern Studies, describes the palace, known as Kemune, as a carefully designed building with mud-brick walls up to 2 meters (6.6 feet) thick.

The team also found wall paintings in shades of red and blue, which were probably a common feature of palaces at the time but have rarely been found preserved. “Discovering wall paintings in Kemune is an archeological sensation,” Puljiz said in a press release, “Kemune is only the second site in the region where wall paintings of the Mittani period have been discovered.”

Ten clay tablets covered in cuneiform, an ancient system of writing, were also discovered and have been sent to Germany for translation. “From the texts we hope to gain information on the inner structure of the Mitani Empire, its economic organization, and the relationship of the Mittani capital with the administrative centers in the neighboring regions,” Puljiz added.

Archeologists first became aware of the site in 2010 when water levels in the reservoir were low, but this is the first time they have been able to dig. However, the site was submerged(淹没) shortly after the dig, Puljiz said, adding“It is unclear when it will come out of water again”.

8 . Are you relatively skinny but growing a “beer belly”?

Then don’t be surprised at your next checkup if the nurse measures your waistline to determine your healthy weight. That’s because research is showing that a protruding (鼓出的) belly may be a sign of VAT — a dangerous form of fat around organs deep inside your body. “Studies confirm that visceral (内脏的) fat is a clear health risk,” said Dr. Tiffany Wiley, a senior expert at the National Institutes of Health in Bethesda, Maryland. Unlike the fat just under your skin, visceral fat raises your risk for heart disease. Experts think that’s because visceral fat raises blood pressure and inflames (使发炎) tissues and organs.

However, you can’t assume you’re safe from visceral fat if your overall weight is healthy, experts stress. That’s because you can have dangerous visceral fat even if you’re not considered overweight — and not have any visceral fat even if you are overweight.

How do you know if your stomach is protruding into dangerous size? Do a check. Non-pregnant women with a waist size greater than 88 cm and men with a waist larger than 102 cm, are at higher risk according to the US Centers for Disease Control and Prevention. If you’re Asian, it drops to 80 cm for women and 90 cm for men. But it is only a rough measure. “The only sure way to know is to check your visceral fat levels on a CT scan or MRI,” say experts.

According to the AHA committee, the most salutary physical activity to “shrink” belly is aerobic exercise. Aerobic means “with oxygen”, so aerobic exercise increases your breathing rate and promotes the circulation of oxygen through the blood. This type of exercise makes the heart work more effectively and improves its ability to move oxygen-carrying blood with every beat. Speed walking, jogging, stair climbing, cycling and swimming are all examples of aerobic exercise.

“However, more studies are needed to determine the best physical activity, food and other lifestyle changes to reduce heart disease risk,” Dr. Tiffany Wiley added.

A．Enlarged organs inside the body.	B．Higher risk of heart disease.
C．Raised mental pressure.	D．Inflamed stomach.
