We all enjoy the colors of autumn leaves. Did you ever wonder how and why a fall leaf changes color? Where do the yellows and oranges come from? To answer those questions, we first have to understand what leaves are and what they do.

Leaves are nature's food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose, which is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis, which means " putting together with light. " A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is what gives plants their green color.

As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter.

During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange colors. Small a-mounts of these colors have been in the leaves all along. Covered up by the green chlorophyll, we just can't see them in summer.

The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves.

It is the combination of all these things that make the beautiful colors we enjoy in the fall.

When was the last time you did something really fun with one of your parents—just the two of you?

Parents who take their young children to music, swimming and art classes often stop arranging such activities once their kids are older and in school all day. But it doesn't have to be that way. Doing something enjoyable with your kids just might make you look at each other in a whole new way, especially if you do it through a class or an event. When parent and child become students together, it puts them on the same level, at least for a while.

“I really like parents to come to class with their kids—they start sharing things and talking about what they're doing and what they like，” said art teacher Pyper Dixon.

However, finding something new in common is a big choice for them, especially when kids get involved in sports and other after­school activities. But it's possible to learn a new skill or hobby together.

That's certainly true of Lauren, 11, of Silver Spring, who is in Dixon's class with her father, Dennis. “I was just going to drop her off，” Dennis said, “but Dixon persuaded me to stay.”

Now Lauren gets to nag her father about doing his art homework. “He always leaves it to the last minute，” she said.“But then he'll turn around to do amazing drawings，” she added, “We have different styles of drawing, so it's interesting to talk it over with him.”

Without the Saturday morning art class, Dennis said, he would be reading the paper, and Lauren would be on her own in her room or on the computer. But they talk more now. “I can't think of an experience where you communicate with your kid so closely，” he said.

1.The author raises the question at the beginning to ________.

A．expect an answer

B．criticize some parents

C．introduce the topic

D．support his argument

2.What does Dixon think is the benefit of parent and child studying art together?

A．The two will become equal.

B．The two will communicate more.

C．The child will learn art much better.

D．The parent will learn something new.

3.The underlined word “nag” in the text probably means ______.

A．urge　　　　　　    B．help

C．ignore　　　　　　     D．teach

4.We can learn from the text that ________.

A．Lauren used to talk a lot with her father

B．Dennis enjoys studying art with Lauren

C．Lauren dislikes her father's drawings

D．Dennis likes playing computer games

Did you know that almost 100% of the materials in your mobile phone can be recovered and recycled to generate energy or make new products, such as plastic products, electronics or even jewelry? Every mobile phone contains significant amounts of copper, aluminum, gold, plastic and other non-metals that can be recycled and reused.

The Singtel x SingPost E-waste Recycling Programme, launched on World Environment Day, 5 June 2017, is a cooperation between the two leading ICT and postal companies as part of their environmental sustainability efforts.

Called ReCYCLE, the programme provides the means for people to do their part for the environment by recycling their mobile and internet related electronic waste such as mobile phones and chargers, laptops and tablets, modems and routers, and other related accessories(配件).

These unwanted devices can be dropped off into the ReCYCLE bins at selected Singtel Shop and Singtel Exclusive Retailer outlets and Post Offices. You can also ask for a ReCYCLE envelope from any Singtel Shop and Singtel Exclusive Retailer outlets, and Post Offices, and mail your mobile device and accessories at no charge.

This programme reduces waste as it ensures that the valuable metals and components the devices contain get recovered. However, e-waste that is often thrown away, including all the precious metals that it contains, will be burnt and landfilled at Semakau Landfill.

Is the data in my e-waste safe when sent for recycling?

We assured that all storage media devices like SIM cards, memory cards, USB flash drives and hard drives are safe for recycling. Cimelia, our e-waste recycling partner is a reliable and NEA-licensed company, which are only interested in extracting(提取) the precious metals from the devices, NOT the data in them. The devices will go through a crushing process for secure destruction after the whole extraction process.
