One morning I wasted nearly an hour watching a tiny ant carry a huge feather．Several times, it 36 obstacles（障碍物in its path．And after a pause it made the necessary detour. At one point, the ant had to 37 a crack(裂缝) about 10 mm wide．After some brief thoughts, the ant laid the 38 over the crack, walked across it and 39 up the feather on the other side, then continued on its way．I was 40 by the cleverness of this ant．It was only a small insect, lacking in 41 yet equipped with a brain to reason, explore, discover and overcome. 42 this ant, like the other two-legged creatures 43 on the earth, also shares human feelings．
After some time the ant finally reached its 44 – a flower bed and a small hole that was the entrance to its 45 home．It was there that the ant met its 46 . How could that large feather possibly 47 such a small hole? Of course, it couldn’t．So the ant, after all this trouble and using great brightness, overcoming problems all along the way, just 48 the feather and went home. The ant had not thought the problem through 49 it began its journey and in the end the feather was 50 more than a burden. Isn’t our 51 like this?
We worry about our families; we worry about our money or the 52 of it; and we worry about all kinds of things．These are all 53 —the things we pick up all the life, and drag them around the obstacles and over the cracks that life will bring, only to 54 that at the destination they are 55 and we can’t take them with us．

Fifteen percent of US teenagers aged 12 to 17 who own mobile phones have received nude（裸体）or nearly nude images of someone they know, according to a survey released on Tuesday.
Only four percent of mobile phone-owning 1 in that age group have sent sexually suggestive pictures of themselves, a practice known as "sexting," 2 the Pew Research Center’s Internet & American Life Project.
The Pew survey found that girls and boys were equally as likely to have sent a suggestive picture to 3 person and 4 teenagers were more likely to have engaged in "sexting."
Eight percent of 17-year-olds with mobile phones have sent a sexually provocative（刺激的） image 5 texting and 30 percent have 6 a nude or nearly nude image on their phone.
Only four percent of 12-year-olds have sent suggestive images of 7 .
Amanda Lenhart, a senior research specialist at Pew and the author of the report, said sexually suggestive images have become a 8 of "relationship currency" for teens.
"These images are 9 as a part of or instead of sexual activity, or as a way of starting or 10 a relationship with a significant other," she said. "And they are also passed 11 to friends for their entertainment value, as a joke or for 12 ."
"The desire for risk-taking and sexual exploration during the teenage years 13 with a constant connection via mobile devices creates a 'perfect storm' for sexting," said Lenhart.
"Teenagers have always grappled with issues around sex and 14 , but their coming-of-age mistakes transgressions have never been so easily 15 and stored for others to see," she added.
The survey found that teens with unlimited text messaging plans were more likely to receive "sexts" 16 images of people they know. About 75 percent of mobile phone owning teens have unlimited plans.
Among this group, Pew said 18 percent reporting receiving "sexts" 17 with eight percent of teens on 18 data plans and three percent of teens who pay per message.
According to Pew, 58 percent of 12-year-olds own a mobile phone and 83 percent teens aged 17 19 .
Pew noted that a number of US states are grappling with how to 20 "sexting" among minors and some legislatures(立法机关) have stepped in to consider laws that would downgrade charges from felonies（重罪） to misdemeanors（轻罪）.
Pew conducted telephone interviews with 800 teens aged 12 to 17 and their parents between June 26 and September 24.

Elderly people who drink several cups of green tea a day are less likely to suffer from depression, probably due to a "feel good" chemical found in this type of tea, Japanese researchers said.
Several studies have 1 drinking green tea to lessening psychological problems and Kaijun Niu, of Tohoku University Graduate School, and colleagues found people 2 70 and older who drank four or more cups of green tea daily were 44 percent 3 likely to experience depression.
Green tea is widely 4 in many Asian countries, 5 China and Japan.
Niu's team 6 1,058 relatively healthy elderly men and women. About 34 percent of the men and 39 percent of the women had symptoms of 7 , according to the study that was 8 in the American Journal of Clinical Nutrition.
A total of 488 participants said they 9 four or more cups of green tea a day, 284 said they downed two to three cups 10 and the rest reported having one or fewer cups daily.
According to the researchers, the 11 effect of drinking more 12 tea on alleviating symptoms of depression did not 13 after they factored in social and economic status, gender, diet, history of medical problems and 14 of antidepressants.

Seasonal influenza is characterized by a sudden fever, cough, headache, muscle and joint pain, sore throat and runny nose. Most people recover from fever and 1 symptoms within a week without requiring medical attention. But influenza can 2 severe illness or death in people at high risk. The time from infection to illness is about two days.
Yearly influenza epidemics can 3 affect all age groups, but the highest risk of complications occur among children younger than age two, adults age 65 or older, and people of 4 age with certain medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases, or weakened immune systems.
Seasonal influenza 5 easily and can sweep through schools, nursing homes or businesses and towns. When an 6 person coughs, infected droplets get into the air and another person can breathe them 7 and be exposed. The virus can also be spread by hands infected with the virus. 8 transmission, people should cover their mouth and nose with a tissue when coughing, and 9 their hands regularly.
Drugs for influenza are 10 in some countries and effectively prevent and treat the illness. Some influenza viruses develop 11 to the antiviral medicines, limiting the effectiveness of treatment.
Influenza epidemics occur 12 during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million 13 of severe illness, and about 250 000 to 500 000 deaths.
Influenza can cause serious public health and economic problems. In 14 countries, epidemics can result in high levels of worker absenteeism and productivity 15 . 16 most people recover from a bout(轮) of influenza, there are large numbers of people who need hospital treatment and many 17 die from the disease every year. 18 is known about the effects of influenza epidemics in developing countries.
The most 19 way to prevent the disease or severe outcomes from the illness is vaccination. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care 20 high risk individuals.
