Our “Mommy and Me” time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride the bikes up and down. “I wish I could take one of my children out alone,” said Christie.

    Then we worked out a plan: When Christie takes one of her children out, I'll watch her other three. And when she watches two of mine. I'll take someone out.

    The children were extremely quick to accept the idea of “Mommy and Me” time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. “She's like a different child when there's no one else around,” Christie shared with me quickly. With her mother all to herself, McKenzie didn't have to make an effort to gain attention.

    Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering (口吃的) son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And another son, Sam, who's always a follower when around other children shines as a leader during our times together.

    The “Mommy and Me” time allows us to be simply alone and away with each child-talking, sharing, and laughing, which has been the biggest gain. Every child deserves to be an only child at least once in a while.

Biofuels (生物燃料), gained from plants and animal matter, are a key solution to the environmental problems caused by fuels like coal. "Bioalcohol (生物酒精) is the most common biofuel and is produced by sugars found in materials such as corn. With some engine redesigned, it can be used directly by cars, buses, etc. ," says Professor Daniel Tan, "12 percent of transport fuel could come from biofuels, especially bioalcohol, by 2030. "

But a 2016 study of biofuels said, "Bioalcohol presently is mostly produced with food crops. Altogether, the environmentally-friendly biofuels rely on about 2-3 percent of the global water and land used for agriculture, which could feed a large number of hungry people. "

Energy experts have therefore been trying to deal with the problem. Recent research led by an international team found that the agave (龙舌兰) plant might offer a way out. This plant tends to be the right bioalcohol source to supersede others such as sugarcane (甘蔗) and corn.

Daniel Tan explains that the agave can be grown in unfavorable conditions and is not a major food crop. "It can grow in areas that lack water and rainfall without being watered by farmers, and it does not compete with food crops or put demands on limited water. This kind of useful plant is recently being grown in Australia. It can survive Australia's hot summers," he says.

The study finds that sugarcane produces just a little more fuel per square meter each year than the agave. However, the agave outperforms sugarcane in a range of areas, including pollution to the earth, and water using. The agave uses 69 percent less water than sugarcane and 46 percent less water than corn for the same amount of fuel produced. As for corn，it produces less fuel per square meter each year than the agave.

However, Daniel Tan states: "The first generation of bioalcohol from the agave recently faces a big competition from oil, whose recent low price makes it far more attractive to customers. Without some policy support from the government, bioalcohol production from the agave faces big challenges. "

Although I learned English for years. I could not speak in complete sentences when I studied in London as an exchange student. In the beginning, I even needed to think twice before replying to a simple greeting. {#blank#}1{#/blank#}If you have a similar experience, here are some tips. 

Practice "output" more often; {#blank#}2{#/blank#} It's OK to start with only simple sentences or short paragraphs. Meanwhile, you can even practice your grammar.

At the time I didn't have opportunities to talk with the local people. So, I self-talked to describe what happened around to myself.

Another method is that you can record yourself speaking and then listen to the recordings to identify areas that needs improving. {#blank#}3{#/blank#}

Language is not a hard science. It is more than just a set of rules, but a means of communication. Like small children picking up their mother tongue, we can get speaking skills more naturally by becoming completely involved in the language and using it. When using a language, we focus on the idea itself, rather than the rules.

Find the "support group" that suits you, 

Find a native tutor. A language tutor is a great idea where you can practice regularly and get your mistakes fixed in time. {#blank#}5{#/blank#} I feel much less shy when I speak English with other non-native speakers there. For example, joining a language group is really a great way to practice output.

A. Communicate with local children.

B. Raise your mind like a kid.

C. It is of much benefit to write in the language.

D. It was so painful that I was so confused about my language ability.

E. Or try some language clubs.

F. It is easier for you to "open your mouth".
