【推荐1】Humans were designed to stand upright(直立). And yet in this modern world, too many of us spend our days with our heads lowered for a simple reason: we’re staring at the tiny screen of a smartphone.

People spend an average of 2 to 4 hours each day with their neck bent while shooting off emails or texts. That’s 700 to 1,400 hours a year. The success of social media has led to a rapid development of bad smartphone posture(姿势). That’s 700 to 1,400 hours a year. The success of social media has led to a rapid development of bad smartphone posture.

The average adult head weighs 10 to 12 pounds when it’s in the upright position. However, because of the gravity, bending your head at a mere 15 degree puts 27 pounds of pressure on your spine(脊椎); a 30 degree neck bend could equal 40 pounds of a pressure; a 45 degree bend adds the force of 49 pounds, according to research from Dr. Kenneth Hansraj from New York. These stresses may lead to many problems.

It’s no secret that correct posture is better for your back. According to the researchers, good posture is described as ears aligned(成一条直线) with the shoulders. In proper alignment, spinal stress disappeared. It is the best position for the spine. Standing tall doesn’t just make you look better; it improves your health, too. Other studies have found good posture has even been connected to ways of behaving. People who have poorer posture often have poorer physical and emotional(情绪上的) health.

The researchers describe bad posture as “the head in a forward position and the shoulders dropping forward in a rounded position”. Bad posture has been connected to many medical problems, including headaches and other problems, depression and heart disease. This is why Hansraj said it’s important to be mindful of your smartphone posture. While it is nearly impossible to avoid the technologies that cause these problems, people should make an effort to look at their phones with a correct posture.

【推荐2】下面文章中有3处需要添加小标题。请从以下选项（A、B、C和D）中选出符合各段意思的小标题，并在答题卡上将相应选项的标号涂黑。选项中有一项是多余选项。

Think of the body like a school. At the top of the school is the headmaster, known as the brain. This is the organ that controls the rest of the organs, just like the headmaster controls the school. After this comes the heart. It is like a teacher. This organ pumps the blood around the body so it can run well.     1     Next is the liver, which is the only one that can regrow itself. It helps to clean the blood. This is like the knowledge students get from teachers. Students always grow with newly found knowledge. The lungs are the organs of the body that use the oxygen we breathe. Think of the oxygen as the life we lead at school. The stomach is very useful as it stores the food we eat until we can digest it properly.     2     We store the information until we need to use it. So this organ is like a notebook. The kidneys are the organs that remove waste products from the blood and produce urine.     3     Now you can see how similar our school life is to our body and we can look after them both.

A．They are like the cleaners, repairmen and security guards who look after our school.

B．This is similar to the learning process.

C．This is what we learn at school.

D．This is similar to the knowledge a teacher gives to students.

【推荐3】What do Leonardo da Vincii, Marie Curie, and Albert Einstein have in common? They were all left-handed, along with other famous people including Brad Pitt Prince William, and Barack Obama. In fact, an estimated 13 percent of the world's population may be left-handed and still most people around the world are right-handed.

What makes a person become right-handed rather than left-handed? As yet no one really knows for sure. One simple idea suggests that people normally get right-handedness from their parents. Studies have found that two right-handed parents have only a 9.5 percent chance of having a left-handed child, whereas two left-handed parents have a 26 percent chance of having a left-handed child. Another common theory is that left-handed people suffer mild brain damage during birth, which makes them left-handed. However, if this theory were true, it would not explain why the percentage of left-banded people is so similar in every society, when birth conditions vary so much from society to society.

Whatever the reasons behind it, people's attitudes toward left-handedness have changed a lot over the years. Statistics show that although 13 percent of young people (10-20 years old) are left-handed, only 6 percent of the elderly are left-handed. Left-handed children used to be punished until they began using their right hand like other children, but today people who are left-handed are no longer looked down on nor are they considered abnormal. For most people today, either case is perfectly acceptable.

1. What makes one right-handed?

A．The environment.

B．Mild brain damage during birth.

C．The reason is uncertain.

D．Other people.

2. Why is the number of young people who are left-handed bigger than that of the elderly?

A．Because the elderly are forced to become right-handed.

B．Because left-handed people are considered abnormal.

C．Because left-handedness can be cured.

D．Because the young are easily damaged.

3. What does the text mainly talk about?

A．Left-handed people are looked down upon.

B．General facts about left-handed people.

C．Some famous left-handed people.

D．The reasons why people are left-handed.

【推荐2】Surfing the Internet for fun will make you a better employee, according to an Australian study.

The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not. Study author Brent Coker said, “Surfing the Internet at times helps increase an employee's attention.”

“People need to relax for a bit to get back their attention,” Coker said on the university's website. “Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day's work, and as a result, increases productivity (生产效率),” he said.

According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos. “Firms spend a lot of money on software to block their employees from watching videos, using social networking sites or shopping online,” said Coker. “That's not always a good idea.”

However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without.” he said.
