Old-fashioned carpooling (拼车) where a group of people take turns driving each other to work has always faced a resistance. In a study by ABC News, 84％of those who drive to work say that they still do it alone.{#blank#}1{#/blank#} For example, sometimes they simply cannot find anyone to share a ride with.

    {#blank#}2{#/blank#} NuRide, a company providing online carpooling service, offers daily travelers not just a web-based list of would-be carpoolers but also a way to arrange a trip online. Here's how it works: rider seekers enter the positions where their trip will begin and end, the time they want to leave and if they're willing to drive or just ride in someone else's car. The website's search engine then looks for matches and makes lists of the names of traveling companions, along with the car model and the exact time and place to meet for each trip.{#blank#}3{#/blank#} Then they meet their car mates when it's time to go.

    {#blank#}4{#/blank#} They are required to provide the name of their employer and a work e-mail address. Both need to be checked before being listed on the website.

       So far, NuRide has arranged more man 50,000 rides on the website.{#blank#}5{#/blank#}

A. NuRide users aren't riding with total strangers.

B. It has resulted in 1.4 million fewer miles driven.

C. They insisted that carpooling is just too inconvenient.

D. Now technology makes carpooling easier and more fun.

E. It is an environmentally friendly and economical way to travel.

F. Carpooling reduces travel cost, such as fuel cost and stress of driving.

G. People who want to share the ride can show their interest in joining in online.

    Lindsay Renwick, the mayor of Deniliquin, a country town in New South Wales, misses the constant whir（嗡嗡声）of the rice mill whose giant fans dried the rice. The Deniliquin mill, the largest rice mill in the Southern Hemisphere (南半球), once processed enough grain to meet the needs of 20 million people globally. But six years of drought have had a destructive effect, reducing Australia's rice crop by 98 percent and leading to the mothballing of the mill last December.

    Drought affects every agriculture industry based in Australia, not just rice – from sheep farming, the country's other backbone, to the cultivation of grapes for wine, the fastest-growing crop there, with that expansion often coming at the expense of rice. The drought's effect on rice has produced the greatest impact on the rest of the world, so far. It is one factor contributing to skyrocketing prices, and many scientists believe it is among the earliest signs that a warming planet is starting to affect food production.

    Researchers are looking for solutions to global rice shortages – for example, rice that blooms earlier in the day, when it is cooler, to fight against global warming. Rice plants that happen to bloom on hot days are less likely to produce grains of rice, a difficulty that is already starting to emerge in inland areas of China and other Asian countries as temperatures begin to climb. 'there will be problems very soon unless we have new varieties of rice in place,” said Reiner Wassmann, climate change director at the International Rice Research Institute (IRRI). The recent reports on climate change carried a warning that could make the news even worse: that existing models for the effects of climate change on agriculture did not yet include newer findings that global warming could reduce rainfall and make it more variable.

    Yet the effects of climate change are not uniformly bad for rice. Rising concentrations (浓度) of carbon dioxide, the main greenhouse gas, can actually help rice – although the effect reduces or disappears if the plants face unnecessary heat, inadequate water, severe pollution or other stresses. Still, the flexibility of farmers here has persuaded some climate experts that, particularly in developed countries, the effects of climate change may be relieved, if not completely avoided. “I'm not as negative as most people,” said Will Steffen, director of the Fenner School of Environment and Society at Australian National University. “Farmers are learning how to do things differently.”

    Meanwhile, changes like the use of water to grow wine grapes instead of rice carry their own costs, as the developing world is discovering. “Rice is an essential food,” said Graeme Haley, the general manager of the town of Deniliquin. “Wine is not.”

    The steady increase in women having babies later in life is undeniable. First-time mothers are more likely to be 35 or older than their counterparts (对应者) from two decades ago, according to the Pew Research Center. While the number of first-time moms between ages 20 and 24 falls, the number of births to women in their 30s and 40s keeps growing. In addition, recent wide-ranging studies have found significant long-term benefits in waiting to have babies. These benefits counterbalance (抵消) some worries about being an older mother and the effects it may have on children.

    Longevity for women who wait

    A study in the journal Menopause examined older mothers' life expectancy (寿命) and found that women who had their last child after the age of 33 are more likely to live to 95. In fact, researchers reported that these women had twice the chance of living to 95 or older than those who had their last child before their 30th birthday. The news for women having babies after 40 is equally promising.

    Boosted brainpower for older mothers

    It's also possible that later pregnancies (怀孕) protect against cognitive decline. Researchers at the University of Southern California found that women have better brainpower if they have their last baby after age 35. The researchers looked at the pregnancy history of a group of 830 women ages 41 to 92. Their research provides strong evidence of a positive association between later age at last pregnancy and late-life cognition.

    Increased income over time

    There's a measurable link between the age you have your first child and income gains and losses. Women who start their families when they are older are likely to increase their earning potential.

    Educational and emotional support for children

    Older parents who are less stressed about income or job security tend to be more patient and can spend more time with their children. Parents who have more secondary education can also offer more specific stimulation to their children, which can be helpful for development. An investigation of 8- to 12-year-olds explored how specific parenting beliefs and behaviors—such as reading, constructive play and emotional support—affected child development. The research published in the Journal of Family Psychology found that parent education and income positively affect child achievement.

    Having babies later in life

    Cross-country skiing can be enjoyed by a wide range of students, from the youngest kindergartners to those secondary students. It is really a fun activity, providing students a gentle workout outside in winter. While having fun, students can gain physical and mental benefits.

    The physical benefits of cross-country skiing are well-known. If we look at Olympic cross-country skiers, we can see the positive effects on the body that result from training for cross-country skiing.

    The average best female cross-country skiers carry 11 percent body fat, and best male skiers carry 5 percent. These percentages are well below the average people who are considered to be athletic—17 percent for females and 10 percent for males. Burning a high number of calories while skiing helps to keep skiers slim in a healthy and attractive way.

    Cross-country skiing is also an efficient way to exercise a large number of muscles at once. The upper body gets much more of workout because skiers use ski poles as a means of propulsion (推进), the force that drives skiers forward. Of course, the leg muscles also do their fair share. People who use cross-country skiing as a workout over several weeks will discover that the muscles of their whole body increase in strength.

    Cross-country skiing on a regular basis has a tremendous effect on a person's cardiovascular (心血管的) system. In addition to gaining strength in the muscles of the upper and lower body, people who use cross-country skiing as a workout method over several weeks will also discover that their heart is stronger. A strong heart pumps more efficiently, sending out more blood to the muscles with each contraction (收缩). Through weeks of skiing, people often discover that their resting heart rate has decreased. Highly trained Olympic cross-country skiers have resting heart rates between 28 and 40 beats per minute. Compare that to the resting heart rate of the average person, which is 60 to 80 beats per minute!

    The benefits of cross-country skiing extend beyond overall general health. A lot of evidence exists showing that regular physical activities increase the release of mood-lifting endorphins  (内啡肽) in the body. After fun skiing lessons, students will be full of energy; they will be relaxed and in a better mood than when they started class. Students will leave class with a sense of accomplishment, knowing that they have developed new skills in a fun activity.

Cross-country skiing is a great way to exercise the whole body. Now more and more students are taking part in this exercise outside during the winter months. They are enjoying it and benefiting from it!

    Six Things You should Never Do Before the Queen

    ※Don't show up empty handed.

    What do you get the woman who already has everything? Sure, the Queen has several homes full of priceless trinkets（饰品）, but bringing a gift is necessary. {#blank#}1{#/blank#} So if she's paying a visit to your hometown or country, something which reflects local culture might go down better than W.H. smith's vouchers（优惠券）.

    ※{#blank#}2{#/blank#}

You may be dead on your painful feet—but you should always stand when the queen enters the room. You may only sit once she has taken the seat, so keep a close eye on when the Queen sits down herself.

    ※Don't ignore the dress code.

    Regardless of how late you're running or how tempting it is to stay in your casual clothes, make sure you dress accordingly when meeting HRH. {#blank#}3{#/blank#}

    ※Resist the temptation to refer to her by her first name.

    While the Royal family may be extremely familiar to us, and while we may have our own nicknames for them, we common folk still aren't on a first name basis with them. So, when you meet the Queen she should be addressed as “Your Majesty” and “Ma'am” consequently after. When she leaves, however, you must address her as “Your Majesty” once again.

    ※Only speak if the queen speaks to you.

    Remember when you were a small child and all your elders would drop wisdom such as “don't speak unless spoken to first” and “children should be seen and not heard”? {#blank#}4{#/blank#} This rule exists so Her Royal Highness can control every aspect of the conversation-- including exiting it swiftly.

    ※Don't eat before she does.

    No matter how tasty and tempting the banquet morsels spread in front of you look, you can only start eating once the Queen does. So perhaps have a quick snack beforehand, in case any speeches go on for a long time. {#blank#}5{#/blank#}

A. Stand to attention.

B. Watch out for Queen.

C. Oh, and if she has finished eating, you'd better be full too.

D. If the event is black tie, wear black tie.

E. You are supposed to listen to them though you've grown up.

F. This gift must also be appropriate to the occasion.

G. The same applies to meeting the Queen.

    Every summer, hundreds of thousands of students travel to other countries looking for work and adventure. Most of the opportunities are in seasonal work, mainly connected with tourism and agriculture. The pay is usually poor, but most people work abroad for the thrill of travel. You can pick grapes in France, work on a family campsite, entertain kids on American summer camps, and of course, there are always jobs in hotels and restaurants.

    But it is not as easy as it used to be to find work. "Unless you speak the language of the country will, there will be very few openings." Says Anthea Ellis, an adviser on vacation work for students. "If you work as a nanny with a family in Italy, then of course you'll have to speak Italian. When you arrive to wash dishes in a restaurant in Paris, the owner will expect you to speak French."

    Not everyone enjoys the experience. Sarah James was an assistant responsible for a summer camp group of forty America children in Europe. One child lost his passport; another became seriously ill and was flown home; four children were lost in Madrid for a whole day; the whole group was thrown out of one hotel because of the noise they made. "I did visit a lot of new places," she says, "but it wasn't worth it. The pay was awful and really was a 24-hour-a-day job. The kids never slept!"

    "The trouble is, students expect to have an easy time of it," Anthea Ellis points out. "After all, they see it as a holiday. In practice, though, you have to work hard. At the same time, all vacation work is casual work. You'll have a job when the hotel, the restaurant, or the campsite is busy and you have few employment rights. As soon as the holiday season finished, they'll get rid of you. If you don't work hard, or if your employer doesn't like you, you'll get fired."
