What Recycling Will Look Like in 10 Years
As businesses rush to become greener, this is what recycling may look like a decade from now. To begin with, more goods will be made of existing materials. The increase in the reuse of existing materials, including recycled plastics, glass and more will reduce the demand for raw materials (原材料). You’ll find more clothing, toys, park benches, etc. made of recycled water bottles. 1.. Thus all resources will be kept in circulation (流通) with no end.
Reusable products will become more popular. Not only will companies take up the duty to reduce waste. 2.. Take single-use straws (吸管), for example. They’ve been banned everywhere because they are so bad for the environment and wildlife. Furthermore, beginning in 2021 the European Union will ban single-use plastics. 3.; we also need to change consumers’ habits by changing the way they think about single-use plastics.
Chemical recycling may become common. Though the field is still in its early stages, the process of chemical recycling may increase in the coming years. 4.. “This is all just a huge expensive business,” Denise Patel said, adding that reducing the overall use of plastic is a better solution.
5.. Currently, thin plastic isn’t often recycled. As it’s so lightweight, it can jam recycling machinery；but throwing it out isn’t ideal either. After all, it takes about 450 years to break down. You can return it to a store that collects them, or use a service that picks up hard-to-recycle items from your home for a fee.
A. We cannot rely only on recycling
B. New plastic is cheaper than recycled plastic
C. In the future, thin plastics will be recycled more readily
D. However, chemical recycling is not without disagreement
E. This creates an economy where no resource will be wasted
F. Individuals (个人) will also be expected to use more reusable products
G. The campaign puts the focus on individuals to clean up their plastic mess
“ New and improved. ” These words are put in so many marketing campaigns that we tend to accept them as linked. But many new drugs aren't an improvement over the best existing drug for a given condition, and the fast drug-approval processes in recent years have added to the uncertainty about their advantages.
A recent report in the British Medical Journal, "New Drugs: Where Did We Go Wrong and What Can We Do Better?, analysed the issue, The authors looked at 216 drugs approved between 2011 and 2017 ； 152 were newly developed, and 64 were existing medicine approved for new uses. Only 25% offered a major advantage over the established treatment, and fully 58% had no confirmed added benefit to reduce symptoms or improve health-related quality of life.
"This doesn’t mean there's no added benefit," lead author Wieseler said. “It just means we have no positive proof. Either we have no studies or have studies not good enough. ” Wieseler and her co-authors work for a German institute which evaluates new treatments and advises on whether the country's health care system should pay a premium ( 占)for them. Such organizations , known as health technology assessment ( HTA) agencies, work a little differently in the US, says Sean Tunis，a researcher in Baltimore: “ If payers think a new drug isn't better than an existing drug，these agencies will require .that hospitals try the cheaper drug first. ”
Germany's HTA demands trials to prove that a new treatment beats the existing standard. This isn't always practical For one thing, such studies can be expensive and time-consuming, with no guarantee of success. Secondly, it can discourage companies from attempting to develop new alternatives. This is already happening. Drug developers are increasingly focused on areas where there are no good treatments to compete with, such as rare diseases.
This lack of meaningful data to guide patients is a major point of Wieseler's paper- With accelerated approval, there are more products approved, with a greater amount of uncertainty about risks and benefits. But there are other solutions besides drug trials. One idea is to require postmarket studies to track the effectiveness of newly approved drugs—a step too often neglected.
1.What message does the recent report convey?
A.Many new drugs have no improved advantages.
B.The approval processes for new drugs are too fast.
C.Improved drugs have advantages over old ones.
D.Before 2017 no improvement was made to drugs.
2.What will US HTA agencies do when no advantage is found in new drugs?
A.Remove government premium on them.
B.Get hospitals to use the cheaper drugs.
C.Arrange financial support for the patients.
D.Put new drugs on further trials and studies.
3.What's the disadvantage of Germany's HTA trial demands?
A.Making drug companies think of illegal ways to cut cost.
B.Pushing companies to try alternatives for existing drugs.
C.Getting patients to depend on the government for support.
D.Holding companies back from improving existing drugs.
4.What is the best title for the text?
A.The Advantage of Existing Drugs
B.Misunderstanding of New and Old Drugs
C.A Dilemma with New Drug Alternatives
D.Peopled Preference for New or Old Drugs
Leaders in the aviation （航空）industry plan to launch a campaign that they hope will work against what they call a " flight shaming（使蒙羞）” movement.

That morning，I dropped our eldest at kindergarten and returned home to let our two younger children play while I worked on my medical report. It was wonderful, but it hit me that my career in hospital wasn't making a difference in anyone's life. I needed something that would stretch my limits and push me to grow. My career enabled me to work from home. I could work from home, and become a foster（领养）mother, providing safety for a child who needed it desperately.
On Monday morning, I picked up the phone and dialed the number I had googled for the nearest Department of Children’ Services. The man on the other end was receptive to my questions and explained the next step of training, involving eight weeks of classes designed to prepare and educate foster parents. We continued through all the classes, the home visits , background checks, and seemingly endless steps.
Five long months after we were approved , the phone Tang. In the middle of the night , I woke my husband and rushed to East Tennessee Children's Hospital- Our placement was waiting for us in the emergency room, sick and lack of nutrition. It didn't take long for us to realize the full depth of her suffering. Six months later, her half-brother came to us by our request. We now had five children under our care.
On August 12, 2016, our family of seven walked into a small courtroom. The children's lawyer and social worker were there. With just a few words, our adoption was finalized. These two amazing children weren't going home, because they were already home. We are their forever family5 and they are our forever children. We may not be able to change the entire world, but we have changed the world entirely for our new children.
