These gaps are especially hard on gibbons (长臂猴); although larger males can leap across some gaps, females and the young can be cut off from food, companions, and even potential mates. Now, a new study suggests a couple of strong ropes could really help bridge the gap.

Gibbons are at risk of extinction across Southeast Asia, largely because of habitat loss. With about 30 individuals left, the Hainan gibbon is considered the rarest primate (灵长类) on Earth. All of these animals live on the Hainan Baw angling National Nature Reserve. In July 2014, a typhoon caused landslides across the reserve, creating gaps in the forest that were difficult for these primates to cross.

To help reconnect the habitats, professional tree climbers set up an artificial “bridge” made of two mountaineering-grade ropes across a 15-meter-wide valley. Nearly 6 months later, the gibbons started to use the bridge to cross the gap, researchers report today in Scientific Reports. The team documented 52 crossings of a group of eight gibbons, with most walking along one rope while holding on to the second rope for support, which the scientists named “handrail”. The gibbons also shimmied underneath the ropes using all arms and legs to the opposite side.

Conservationists previously built artificial bridges to help other species such as the Bornean orangutan and the Javan slow loris. But this is the first example of the rare Hainan gibbon using them. The rope bridges could be a short-term solution to reconnect disjointed (脱节的) habitats, the researchers argue. Combined with efforts to provide enough natural forest cover.

An attraction of sports programs for the major U.S. media company is that events are often held on Saturday and Sunday afternoons — the slowest time periods of the week for general television viewing. Sport events are the most popular weekend programs, especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at relatively high prices during what normally would be dead time for programming. Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of major corporations realize that sports attract male viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers, cars and life insurance.

Golf and tennis are special cases for television programming. These sports attract few viewers, and the ratings(收视率) are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States, including many lawyers and business managers. This is why television reporting of golf and tennis is sponsored by companies selling high-priced cars, business and personal computers, and holiday trips. This is also why the networks continue to carry these programs regardless of low ratings. Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions to buy thousands of “company cars” and computers. With such viewers, these programs don’t need high ratings to stay on the air.

It takes an hour to like someone, and a day lo love someone, but it takes a lifetime to forget someone. Giving someone all your love is never an assurance that they will love you back. Do not expect love in return; but if it does not, be content it has grown in you. Do not rely on one’s appearance； it can trick you. Do not rely on wealth；even that fades away. Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright.

There are moments in life when you miss someone so much that you just want to pick them   from your dreams and hug them. Dream what you want to dream;go where you want to go;be what you want to be,because you have only one life and one chance to do all the things you want to do.

The brightest future will always be basod on a   forgotten past.You cannot go on will in life until you let your past   failures and heartaches go off.May you have enough happiness to make you sweet,enough to make you strong, enough sorrow to keep you human, enough hope to make you happy.The happiest of people do not necessarily have the of everything;they just make you th most of everything that comes along their way.Happiness waits of those who cry,those appreciate the importance of people who have touched their lives. Always put yourself in others’ shoes.If you feel that it hurts you,it probably hurts the other person,too.

When you were born,you were crying and everyone around you was smiling.Live your life so that when you die,you are the one who is smiling and everyone around you is crying.

But many new drugs aren’t an improvement over the best existing drug for a given condition, and the fast drug-approval processes in recent years have added to the uncertainty about their advantages.

A recent report in the British Medical Journal, “New Drugs: Where Did We Go Wrong and What Can We Do Better? “Analyzed the issue. The authors looked at 216 drugs approved between 2011 and 2017:152 were newly developed, and 64 were existing medicine approved for new uses. Only 25%offered a major advantage over the established treatment, and fully 58%had no confirmed added benefit to reduce symptoms or improve health-related quality of life.

“This doesn’t mean there’s no added benefit, “lead author Wissler said. “It just means we have no positive proof. Either we have no studies or have studies not good enough. “Wissler and her co-authors work for a German institute which evaluates new treatments and advises on whether the country’s health care system should pay a premium(补贴)for them. Such organizations, known as health technology assessment(HTA)agencies, work a little differently in the US, says Sean Tunisia researcher in Baltimore: “If payers think a new drug isn’t better than an existing drug, these agencies will require that hospitals try the cheaper drug first.”

Germanys HTA demands trials to prove that a new treatment beats the existing standard. This isn’t always practical. For one thing, such studies can be expensive and time-consuming, with no guarantee of success. Secondly, it can discourage companies from attempting to develop new alternatives. This is already happening. Drug developers are increasingly focused on areas where there are no good treatments to compete with, such as rare diseases.

This lack of meaningful data to guide patients is a major point of Wissler’s paper. With accelerated approval, there are more products approved, with a greater amount of uncertainty about risks and benefits. But there are other solutions besides drug trials. One idea is to require postmarked studies to track the effectiveness of newly approved drugs—a step too often neglected.
