1 . A new study suggests some of America’s favorite Independence Day fireworks can give out lead and copper (铜), which are used to give fireworks their vivid colors, and also damage human cells and animal lungs.
Led by researchers at NYU, the study showed poisonous levels of lead in the fireworks. Experiments showed that lung exposure to particle emissions (颗粒排放物) from five types of fireworks significantly increased oxidation (氧化), a chemical process in the body that can damage or even kill cells.
The researchers say the new study is believed to be the first to examine the effects of firework exposure in human cells and living animals, and to test for particles of common firework metals thrown into the atmosphere.
“While many are careful to protect themselves from injury from explosions, our results suggest that inhaling firework smoke may cause, longer-term physical damage, a risk that has been largely ignored,” says study senior author Terry Gordon, a professor in the Department of Environmental Medicine.
Gordon and his team also analyzed 14 air quality samples taken at dozens of sites across the US throughout each year. They found that levels of poisonous metals were higher in samples taken on Independence Day and New Year’s Eve celebrations than at any other time of the year. Along with lead, copper and other poisonous metals are commonly found in fireworks. “Our research shows that although we are only exposed to these poisonous substances for a short time each year, they are much more poisonous than the pollutants we breathe every day,” says Gordon.
Gordon cautions (警告) that the current investigation is the first step, only addressing the potential effects of one-time exposure to the firework metals. He says repeated exposure is likely a larger concern. Nevertheless, he is planning to share his findings with local health officials, firework producers, the Environmental Protection Agent, and other regulatory agents to alert them to the potential for harm.

When I was a kid, I am inspired by people playing the guitar. Two years ago, there was a program in my school so I signed up as soon as possibly because I was really fond about it. After a week or 2 a paper was send to my mail box saying that I made it. I was extremely happy! Before I bought my first guitars I have practiced it every day for hours and hours. With time passing on, music started to become what I wish do best. Now I perform in many concerts and it is a fun. So if you have a hobby who is what you like doing, turn them into a talent and show the world what you do!

6 . Hundreds of snow leopards(雪豹)are being killed every year across the mountains of central Asia, threatening the already endangered big cat, according to a new report from Traffic.
Snow leopards live in 12 nations but more than 90% of the reported snow leopard illegal hunting takes place in five countries: China and Mongolia, which host most snow leopards, as well as Pakistan, India and Tajikistan, of which each have just a few hundred of the animals.
Over half the so-called "ghosts of the mountains" are killed by farmers for attacks on livestock(牲畜)and 20% are trapped by snares(陷阱)set for other animals. Another 20％ are killed for the illegal fur trade. The report found up to 200 snow leopards are being illegally traded each year. But the number has fallen sharply in recent years, particularly in China, perhaps because of increasing law enforcement(实施).
The leopards are also at risk from climate change, with warming temperatures threatening to leave a third of their habitat uninhabitable. The tree line shifts up the mountains and causes farmers to plant crops and raise livestock at higher altitudes(高海拔).
To reduce the killings, the report's authors recommend the rolling-out leopard-proof corrals(防豹畜栏)for yaks and horses and insurance schemes for farmers. Such schemes are already being tested, for example in a village in the Indian state of Himachal Pradesh. The natural food of snow leopards are Himalayan blue sheep and ibex, but their numbers have fallen as their habitat is turned into farmland.
Stronger law enforcement is also needed, said Traffic. Less than a quarter of cases of snow leopard poaching have been found and just one in seven charged.
"We all should work together to greatly reduce human-wildlife conflict and ensure that mountain communities can co-exist with snow leopards," said Rishi Sharma, from WWF and a co-author of the report. "Compensation schemes and innovative predator-proof corrals are making a difference but we urgently need to expand these to benefit communities and snow leopards across Asia's high mountains."

9 . It is better to keep your mouth closed and let people think you are a fool than, to open it and remove all doubt.
-Mark Twain
You can have something extremely smart, useful or funny to say, but if you say it at an improper time, you could make yourself look foolish.
Throughout history many famous, noteworthy people have taken Mark Twain's words to heart. These wise people knew when to talk and when to keep silent. Many leaders have to learn when to talk and when to keep silent even when it might be difficult to do so. All leaders must choose their words carefully, picking the right time to speak, so that their words can have the greatest impact.
If you learn to develop this skill of knowing when to hold your tongue, you will also become wise, even if people think you are not. Some people, in fact, will underestimate you because they do not know what you are thinking all the time. This can give you an advantage in many situations. When people underestimate you, they do not focus on you, leaving you to make and perform plans without being noticed.
If you think before you speak, you can also improve your listening skills, which is a very important and useful skill to have. Listening is another key trait(特征)for a leader to have, and it is harder to achieve than many people think. First, you have to be quiet, and then you have to listen attentively, with all your attention on what the person is saying to be a good listener. When you learn to stop and think before you speak and when you learn to become a good listener you will be well on your way to becoming a good leader. By being able to listen to the people that work with you and for you, you will be able to make informed decisions.
1. The quotation(引言)from Mark Twain functions as________.| A．an example | B．a thread | C．a comparison | D．a model |
| A．influential people are able to express themselves freely |
| B．many important people didn't take Mark Twain's words seriously |
| C．leaders should attach great importance to when, how and what to say |
| D．the public will not understand them if famous, noteworthy people keep silent |
① You could be underestimated by others. ② People often think highly of you.
③ You can polish up listening skills. ④You will improve your relationship with others.
| A．①② | B．①③ | C．③④ | D．②④ |
| A．He That Talks Much Errs Much | B．Facts Speaks Louder than Words |
| C．Even Homer Sometimes Nods | D．A Still Tongue Makes a Wise Head |
10 . You are supposed to be our future, a new chapter in the story of our lives, but I can't help being angry with you. Only a few weeks old, you're demanding and unreasoning and I'm struggling to see the good that you bring.
To start with, we got on with it, settling into a routine as we were trapped in nappies and nights when you wouldn't settle, but it started to wear me down. You hear about mothers with postnatal depression, but no one talks about the challenges a father has to face: working to put food on the table and a roof over our heads is tough when you've had only a couple of hours to sleep, and we're not supposed to need a break. Men are supposed to never cry. I hope that I can teach you a better way, my son. You're allowed to have weakness, and not keep everything locked up until it bursts.
It came to a head one night, when your mother found me in tears beside your bed. I'd never want to hurt you, but I was terrified by the thoughts I had. I'm doing the best I can for you, and I've gone and got the help I need. Your mother has been so strong, using your grandmother, uncles and friends to help keep our family together while I work through these feelings. The worst part for me is feeling that I'm failing your mother, and that I'm putting all of your needs on her. at a time when she needs help.
There's hope for the future, but it's a slow process. One day I hope you get to read this, and look at me with questioning eyes, because you can't see the man I am right now in the man I'll be in the future.
