In an online class, it is unbelievably easy to let deadlines come to you or even pass you by before you even know it.     3     . Make sure you meet the deadlines. If you are not watching or attending the lecture attentively, a professor's reminder could easily be missed. However you need to do that or find doing that to be most effective, do it. Find writing things down in your online calendar(日历)? Do it.

Ask questions

    4    .Especially if you need extra support, do not be afraid to email your professors. Their job is to support you and answer yon questions, Professors do not actively want their students to fail, so if they can reasonably help yon out. they will.     5     ? Email them!

G．Keeping all the important dates in your hand is not the best way to explore your online

5 . Recycling plastic has always been a stop-start effort, and the wide variety of plastics we produce, the pollution from waste, and other limitations make recycling an economic(经济) problem. It’s estimated(估计)only 9% of plastic ever created has been recycled. But with the help of a chemical process, Canadian Miranda Wang and her company BioCellection want to change that.

Stability is one of plastic greatest qualities and downside. There's limited evidence that some plastics can biodegrade (生物降解)but largely photo-plastics degrade in the sun. It’s a long process, and the truth is that we can only estimate how long it takes. Wang is looking to break the inaction and BioCellection's task is to make most plastic waste recyclable.

She outlines two current methods. One is to take plastics like water bottles, wash them, cut them, melt and reconstitute them. “That's a very limited process” she says, due to the requirement that plastics be “clean” . The other, which can handle dirtier plastics and a level of pollution, is called hydrolysis(热解). Intense heat is applied to break down plastics so they can be reused as oils for energy, but “it’s not economical,’’ she says.

BioCellection’s solution builds on research from over ten years ago, Wang explains, when a US study discovered pure polyethylene powder (聚乙烯粉)could be broken down by a catalyst (催化剂). Wang and her co-founder Jean hit upon a bacterium being able to eat plastic. In the years since, they engineered a comparable catalyst capable of doing the same job, only faster, which even works on plastics no one else can recycle at present. “We have now found a catalyst that is much cheaper than the one that was used before, Wang says.

Currently focusing on plastic films like shopping hags, the three-hour process breaks clown plastic into chemicals that can act as the building blocks for more complex plastic products.

“Right now we’re able to achieve about 70% transformation from plastic waste material to these chemicals,” she adds, saying they’re working to increase that figure.

1. Why has so little plastic been recycled?

A．Plastic is chemically stable.	B．Recycling plastic led to pollution.
C．We produced various plastics.	D．Most photo-plastics degrade in the sun.

2. What does Wang think of the two current methods?

A．Highly effective and dynamic.	B．Expensive and pollution-causing.
C．Limited and energy-consuming.	D．Widely used and recognized.

3. What did BioCellection find effective to recycle plastics?

A．Polyethylene powder.	B．Chemical products.
C．Plastic films.	D．A catalyst.

4. What is the text mainly about?

A．Miranda Wang and her company.	B．A new plastic recycling method.
C．The greatest downside of plastic.	D．Transformation of plastic waste.

6 . Chris Rishworth is a travelling cyclist who would take photos along the journey. He regards it as killing three birds with one stone. Besides exercising, he can also improve his photography skills and raise money for the children in need through holding a photography show. In the past five years, Chris has raised more than one million dollars and helped more than 30 orphans (孤儿) complete primary and secondary school education.

Chris’ photographs have a very wide range of aspects, including impressive natural sceneries, attractive local conditions and customs, and mysterious historic sites, etc， but he believes the most heart-shaking one is the photo of a baby wallaby (沙袋鼠）. It was on August 5th when Chris was on his way to ride through Magnetic Island. Chris saw a helpless baby rock wallaby trying to get into its dead mother s pouch (育儿袋）.The deep brake marks and pieces of glass indicated that the mother wallaby was killed by a car. The sight shook his heart so much that Chris was almost astonished for a while. After taking a photo of this heartbreaking moment, Chris placed the baby wallaby into the basket of his bike and took it to the local wildlife rescue shelter. The workers told Chris, “ It’s quite common to find baby wallabies attracted to their dead mothers — often due to the road kill on Magnetic Island. ” Hearing this, Chris decided to send the photo to related departments to promote further measures to avoid such things happening again.

Rock wallabies have had a tough history in their native country, Australia, as they struggle to fight against extreme weather and keep up with other competitors. The Australian government took a series of protective measures and fought against hunting activities effectively, which made the number of rock wallabies increase. But now, with the development of Magnetic Island, a lot of trucks and private cars flood in, which breaks the previous peace. Experts of the Wildlife Conservation Society ( WCS) warn that self-driving travelers and truck drivers should pay attention to the wild animals on the road or by the roadside while driving.

1. How does Chris find his trip?

A．It brings him fortune.	B．Its influence is worldwide.
C．Its result is satisfactory.	D．It makes his dream come true.

2. What made Chris realize the cause of the mother wallaby's death?

A．The heartbreaking photo.	B．The workers’ words.
C．His travel experience.	D．The signs of the scene.

3. What may be the best title for the passage?

A．A Beautiful Australian Island Discovered by a Travelling Cyclist

B．A Heartbreaking Moment Photographed by a Travelling Cyclist

C．A Wonderful Photography Show Held by a Travelling Cyclist

D．A Badly Injured Baby Wallaby Saved by a Travelling Cyclist

7 . Children under the age of 18 will be allowed up to three hours per week to play video games, according to a notice issued by China's National Press and Publication Administration. Online game companies are required to provide services to minors — from 8 to 9 p. m. on Fridays, Saturdays, Sundays and legal holidays — as a way to safeguard their physical and mental health. Children are playing more and more online games these days. Is it time to limit their online gaming time? What role do parents have? Readers share their opinions.

Rizlared

Online games are addictive, but if children are taught how to manage in a sensible and responsible manner then it is no longer a threat(威胁).To achieve this, parents need to set examples for not being glued to their phones. Teaching is and always will be the best solution to such problems.

Andrew

Good policy. By limiting time spent on online games, kids can spend time doing more useful things to develop their potential. They can go outside and run, jump and swim instead of sitting on a couch at home and playing with a smart phone.

Adam

It is often seen that parents argue with children over cellphones. Most parents can hardly set and enforce the time limit for its daily usage. Some forcibly take away their cellphones, but it will ruin trust and relationship. Even worse, it will make their kids hate them.

Pink

Excessive(过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health. The gaming industry should not put profit- flaking interests as its priority ( 优先事项) . They should act in a socially responsible way to provide an environment for children to ensure their well-being and development.

Lauren

There would be a loophole(漏洞). Children could use their parents’ or other adults’ IDs to avoid real-name registration, thus making it impossible to put this policy in effect. Parents absolutely need to strengthen guidance and supervision to keep their children from gaming addiction.

1. What should kids do according to Andrew?

A．Play online games.	B．Play with a smart phone.
C．Study all the time.	D．Go in for outside activities.

2. What does Pink advise the gaming industry to do?

A．Pay attention to its profit.	B．Focus on kids’ health.
C．Be responsible for kids’ surroundings.	D．Persuade kids lo play more games.

3. What role do parents have according to the passage?

A．They keep hold of their phones.	B．They set examples for their kids.
C．They limit their kids’ time.	D．They blame kids for addiction.
