Most of us don't have millions of dollars to go door- to-door to persuade people to care about climate change. But most of us do have parents.1.Because if we can't convince the people who love us more than anything in the world to take action on climate， who can we convince?
It might be a hard conversation. If you do accept this challenge, here are a few suggestions 2.If you've ever used any poisonous terms, please get rid of them from your vocabulary. Otherwise, you 're making everything worse.
Share a couple of informative articles on the topic. Bill McKibben's article in Rolling Stone is great and very readable.3.The most important thing for them to understand is that on our current path we may no longer have a climate that allows for stable，secure societies within the lifetimes of today s children.
Once these unpleasant facts are laid out, making it clear that you aren't blaming them for this. Your parents likely made their decisions with a strong sense of morality and social responsibility, and could only make those decisions based on the information they had at the time.4.But now that you have provided the new information, talk about how it warns them, and all of us，to behave in new ways.
Encourage them to buy environmentally- friendly goods and services as much as possible. Talk to them about trying to avoid using non-renewable resources and make it clear that this will not be enough.5.
A.Warn them to care about the change.
B.Talk to them with love and respect.
C.There is no need to flood them with data.
D.So let's talk to them about climate change.
E.There are a lot of interesting articles about climate change in it.

G.This is a challenge that requires us all to act as citizens, not just as consumers.
The electricity bill for an average family with 2 children is worth about 1 full salary per year, but the revolutionary EcoVolt could put 50% of that money back into your pocket.
In 2017, a revolutionary new product called EcoVolt hit the market. Initially it was separated from the general public, all because it offered the opportunity for average families to save up to 50% of their monthly energy costs. EcoVolt is a small, simple, affordable, and easy to use plug in unit that stops unnecessary power from entering the electrical cables and overloading the network, EcoVolt is the utility (公用事业) provider' s best-kept secret. They 've been trying to hide it from the everyday power consumer and even have banned the sale of it in retail shops —just to maximize their profit. However, thanks to the internet, the secret is now out, and everyday customers are now attaining the rewards of less power consumption overall, as well as less power used by household appliances. Your household appliances (家用电器) may last longer than previously. Basically, EcoVolt provides the opportunity for you to save between 30 and 50 percent on your energy bill. That's a phenomenal saving and leaves few questions as to why this has been hidden from consumers.
The benefits of EcoVolt are huge, and researchers are convinced this device could spell the end of unaffordable power bills that can cripple the average wage earner at the end of the month. Scientists initially spent many months trying to expose its efficiency, but those studies now prove that EcoVolt should be common in every household.
It's easy to connect, simply by plugging it into your wall, and it's suitable for both standard homes and apartments connected to a power grid (电网). It also has a counter which shows how you're making more efficient use of your energy, all the while allowing you to gain the rewards of a more everlasting household appliance lifecycle. In just 1-2 months, you've made your money back on your initial purchase.

If you're one of the millions of Americans now trapped in home because of the COVID-19，it might feel like you're cooking more than you've ever cooked in your entire life. And maybe you' re planning to reduce your home food wastes. A good way of dealing with them is to learn to make compost (堆肥).
Select your food wastes. Start with fruits and vegetables — the skin of a sweet potato，the top of your strawberry. Also tea bags, coffee grounds, old flowers and even eggshells are good raw materials. Store these food wastes in a container so you can add them bit by bit. The container doesn't have to be bought online. It can just be an old milk carton (纸箱) or an old wooden chest —just work with what you have available. Also, you can store the food wastes in a bag in your freezer or fridge. That's an easy way to avoid odors and insects in your kitchen.
The crucial step is to make the compost mix. In the world of composting you're inevitably going to hear about ''the greens and browns''—the two main elements for your mix. ''Greens'' are typically wet food wastes, like fruit and vegetable peelings. They are a crucial part for the growth of organisms (微生物),''Browns" are typically dry and they are more carbon rich like newspapers, dried leaves，and pine needles. A good thing to remember is when you're layering， put the dry browns on the bottom with the wet greens on the top because they allow water and air to flow. That will make sure organisms can do their job.
How long do you have to wait for the compost breakdown? If it's hot, you could get there in two months pretty easy. If it's cold, you could be there in six months, And for every component to break down, it might be a year.
In the end ''your nose knows'' when the compost is ready. It just smells so woody, earthy, sweet or sometimes sour. The smell can tell how well you work at your compost.
1.What is a good solution to your home food wastes?
A.Make a plan and reduce the wastes.
B.Collect the picked wastes to make compost.
C.Select the wastes and bury them into the earth.
D.Pick the wastes and put them in a bag in your fridge.
2.What plays a crucial role in making the compost mix?

C.Carbon rich materials.
D.Wet ''greens'' and dry ''browns''.
3.Why should the ''browns'' be put on the bottom with the ''greens'' on the top?
A.To help the organism work on the compost efficiently.
B.To save more space for the water and air to flow.
C.To allow the water and air to flow into the container.
D.To make sure the organism can live longer and better.
4.What does the author feel about making compost?

It was unusually quiet in the emergency room on December 25. I didn't think there would be any patients, sighing about having to work on Christmas. Just then five bodies showed up at my desk, a pale woman and four small children.
“Are you all sick?” I asked doubtfully.
“Yes,” she said weakly and lowered her head.
But when it came to descriptions of their presenting problems，things got a little vague. Two of the children had headaches，but the headaches weren't accompanied by the normal body language of holding the head or trying to keep it still. Two children had earaches， but only one could tell me which ear was affected. The mother complained of a cough but seemed to work to produce it.
Something was wrong，but I didn't say anything but explained that it might be a little while before a doctor saw her. She responded，Take your time; it's warm in here.”
On a hunch (直觉)，I checked the chart after the admitting clerk had finished registering the family. No address— they were homeless. The waiting room was warm.
I looked out at the family huddled by the Christmas tree. The littlest one was pointing at the television and saying something loudly and excitedly to her mother. The oldest one was looking at an ornament on the Christmas tree.
I went back to the nurses' station and mentioned we had a homeless family in the waiting room. The nurses, complaining about working Christmas, turned to compassion for a family just trying to get warm on Christmas. The team went into action，much as we do when there's a medical emergency. But this one was a Christmas emergency.
We were all offered a free meal in the hospital cafeteria on Christmas Day，so we claimed that meal and prepared a banquet for our Christmas guests. As seriously as we met the physical needs of the patients that came to us that day， our team worked to meet the needs, and exceed the expectations, of a family who just wanted to be warm on Christmas Day. Later，as the family walked to the door to leave, the four year -old came running back, gave me a hug and whispered, "Thanks for being our angels today.”

It doesn't take decades of life experience to have a great idea, as many of these young inventors have proved.
The Electronic Television
The electronic television was first designed by a 14-year-old kid in 1920. Philo Taylor Farnsworth shared his concept of an image transmitting (影像传送) device, an early design of the electronic television, with his science teacher, drawing diagrams on several blackboards in class.
By the age of 21 Farnsworth had a working model which served as a basis to all later development and versions of electronic televisions, After discovering a collection of technology magazines in the attic (阁楼) of his family's new home, he developed a passion and interest in electronics, which led him to explore inventions in the field of, specifically, the image transmission.
In 1927, a few years out of high school, Farnsworth was the first inventor to transmit a television image of a dollar sign, composed of 60 horizontal lines.
Braille Language
Louis Braille suffered a serious eye injury when he was just 3 years old. Not only did the accident cause him blindness on that side, but the infection spread and blinded the other eye as well. After more than a decade of struggling with the slow system of tracing his finger over raised letters, Braille was 12 when he learned of a method of silent communication originally created for the French military. He simplified it, and in 1824 the Braille language was born.
Popsicles (冰棍)
A lot of kids are easily distracted (分散注意力)—and thanks to the short attention span of 11-year-old Frank Epperson we now have popsicles. In 1905, Epperson, a San Francisco native, was stirring powdered drink mix into a cup of water when something else caught his attention. The mixture was forgotten outside the door, and when Epperson rediscovered the drink in the morning, it was a deliciously portable frozen popsicle. After years of making the frozen treats for friends, and eventually his own. children, Epperson filed for a patent in 1924.
