Are you concerned about the effect of the haze(雾霾) in Singapore on the health of your children? Then you should read the following passage.

"Young children, especially those with lung or heart illness, should avoid outdoor activity at PSI(Pollution Standards Index — used in Singapore) levels above 100," says Dr Biju Thomas.

The immune system(免疫系统) of children is not mature. 1 Exposure to the haze can result in symptoms such as a blocked nose, dry throat, breathing difficulty, and so on.

Children who are exposed to the haze and experience any of these symptoms which are not serious should recover on their own in time if they limit their exposure to the haze. 2

To keep children safe during the haze in Singapore, parents should keep doors and windows closed at home. Ensure children drink plenty of pure water every day.

3 The answer is that there aren’t any N95 masks designed for use by children. That’s because these masks are made to create a seal(密封) around the mouth and nose of the adult user so particles(颗粒) can not get in. 4 Surgical masks may not offer enough protection from the harmful particles in the haze, which is very small (2.5 microns or less). There is usually some gap between the surgical mask and the face, through which the haze particles may easily get in. 5 However, if it is necessary to take children outdoors during a haze, parents may wish to offer children’s surgical mask to their children, if it brings them comfort, such as filtering out the smell from the haze.

A. So during a haze, children are especially at risk.

B. Are N95 masks and surgical masks suitable for children?

C. The available N95 masks may not fit tightly on the face of a child.

D. Allow children to make regular travels from one building to another.

E. However, if the symptoms continue, they should ask a doctor for help.

F. So you can use a conditioner instead of opening the windows regularly.

G. So it is best to keep children indoors to protect them from the haze when the PSI is high.

Researchers have created a backpack that has a computer and medicines in it that can help even untrained soldiers save the lives of wounded troops. Wounded soldiers have a better chance of survival if they get help soon after being hurt and are quickly taken to a hospital or clinic. But soldiers who do not have medical training may not know how to help their injured friends.

Doctors and engineers have developed what they call an “intelligent backpack”.It has a computer and electronic measuring devices. The backpack also has robotic instruments and medicines ready to give to injured troops.

About 16 doctors and engineers from the University of Pittsburgh, Carnegie Mellon University and several other places are working on the project. The U. S. Department of Defense has given money to the project.

Ron Poropatich leads the project. He is a retired army surgeon. He says the backpack will help soldiers care for those who are injured. The devices included in the backpack can monitor a person^ heart rate and blood pressure. The robotic instruments can even tell whether the soldier has a collapsed lung.

The intelligent backpack's computer can compare information gathered about the injured soldier with thousands of similar cases, and quickly tell the best methods to use to save the soldier’s life.

Sometimes, it is not always possible to quickly remove the injured soldier from the battlefield.So,Dr. Poropatich says, the researchers hope to create a backpack that will have devices .that can keep a .soldier alive for a long time. Dr. Poropatich hopes the backpack and its instruments will be ready for testing animals in about three years.

Linda Abraham, co-founder of Scores, a leading digital analytic company, established her organization on a simple premise(前提): hire people you respect, not necessary people you like. Since starting the business in 1999, she has intentionally brought in people she didn’t like but thought they would be good for the team. "They’re almost like allergy shots for your organization," she says.

A few years back, she hired Dan against the wishes of other people on her team. Even during the interview process, he rubbed people the wrong way. But Linda thought he had the right skills and experience. He came from a large tech company and tended to talk a lot about scale, which many people regarded as advocating bureaucracy(官僚主义) — a no-no (不可接受的事) in the start-up culture.

For the first six months, he made regular observations about one of the company’s products and how it could work better. "When I really dug into what he was trying to say, I was impressed," Linda says. While he wasn’t very experienced in his comments (he often described things as "dumb"), he was insightful. "We ended up scrapping (废弃) the job we hired him for and had him take on the improvements he suggested," she says.

Even in the new role, he wasn’t likable. But Linda tried to focus on the content of what he was saying rather than the way he was saying it, and she coached others to do the same. She also invested time in helping Dan understand how he was coming across and what he could do to change his style. Eventually her attitude toward him changed. "I’ve come to like him quite a bit," she says. "He’s ruffled more than a few feathers along the way, but he’s been promoted and has really crushed it."
