I don’t know anyone who has been handed only roses. We all encounter hardships. Some we see coming; others take us by surprise.1.The question is: When these things happen, what do we do next?
When someone is suffering, we need to follow the Platinum Rule:2.Put ourselves in other’s shoes and respond with understanding or better yet, action.
3.It comes from deep within us and from support outside us. It comes from gratitude for what’s good in our lives and from learning in to the suck.4.I learned that when life pulls you under, you can kick against the bottom, break the surface, and breathe again.
Although it can be extremely difficult to grasp, the disappearance of one possible self can free us to imagine a new possible self. After tragedy, we sometimes miss these opportunities because we spend all of our emotional energy wishing for our old lives. As Hellen Keller put it, “5.But often we look so long at the closed door that we do not see the one which has been opened for us.”
A.It can help a person step out of the trouble.
B.Treat others as they want to be treated.
C.When one door of happiness closes, another opens.
D.Death ends a life, but it does not end a relationship.
E.Another way you answer it depends on your ability of recovery.
F.It comes from analyzing how we process grief and from simply accepting that grief.
G.It can be as tragic as the death of a child, or as disappointing as a dream that goes unfilled.
In a major medical breakthrough, Tel Aviv University researchers have “printed” the world's first 3D vascularized (有血管的）engineered heart using a patient’s own cells and biological materials. Their findings were published on April IS in a study in Advanced Science.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” says Prof. Tal Dvir of Department of Materials Science and Engineering, who led the research for the study. “This heart is made from human cells and patient-specific biological materials. In our process, these materials serve as the bioinks, something made of sugars and proteins that can be used for 3D printing of complex tissue models，” Prof, Dvir says. “People managed to 3D print the structure of a heart in the past, but not with cells or with blood vessels (血管).Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future.”
According to Prof. Dvir，the use of “ native ” patient-specific materials is important to successfully engineering tissues and organs.
The researchers are now planning on culturing the printed hearts in the lab and “ teaching them to behave” like hearts, Prof. Dvir says. They then plan to transplant the 3D-printed heart in animal models.
“We need to develop the printed heart further，” he concludes. “The cells need to form a pumping ability ； they can currently contract (收缩），but we need them to work together. Our hope is that we will succeed and prove our method’s efficacy (功效)and usefulness. “Maybe, in ten years, there will be organ printers in the finest hospitals around the world，and these procedures will be conducted routinely. ”
1.What does Prof. Dvir think of an early 3D-printed heart?
A.It was highly practical. B.It was too expensive.
C.It was personalized. D.It was too simple.
2.What do we know about the latest 3D-printed heart?
A.It can be cultured in the lab.
B.It can match a patient perfectly.
C.It has been transplanted in animals.
D.It has been widely used in hospitals,
3.What is Prof, Dvir's attitude to the development of the printed heart?
A.Ambiguous. B.Positive.
C.Disapproving. D.Cautious.
4.What is the author's purpose in writing the text?
A.To explain the basic principle of 3D technology.
B.To introduce a breakthrough of medical research.
C.To doubt the medical value of a new invention.
D.To prove the effectiveness of the new technology.
There are billions of people on this planet, and many of us love to eat meat. Can the demand be filled in a sustainable(可持续的) and affordable way? A bunch of businessmen are not only optimistic but are working to make this happen sooner than you may think.
The environmental effects caused by meat consumption (食用)—waste, animal treatment, health problems and even the greenhouse gas effects that are potentially caused by methane gas produced by cows—have given rise to a number of startups(新兴公司)looking to develop meats in different ways.
For example, San Francisco-based Memphis Meats is developing cell-based meats in its labs without requiring any animals. Israel’s Future Meat Technologies is doing the same by producing fat and muscle cells that are being tested by chefs in Jerusalem. All of these companies use special processes to harvest cells from animals and grow them in a lab.
But don’t worry if you’re not a meat lover. Startups such as Jet Eat, which is also based in Israel, are working on food products grown in labs that are plant-based and replicate (复制) meats using natural elements while still keeping flavor, consistency and the “overall sensory experience”, according to a report on NoCamels. Jet Eat, which was founded in early 2018, aims to 3D-print their lab-grown products by 2020.
As you can imagine, there are plenty of barriers facing the industry. Educating the public is a big one. Another controversial issue is the labeling of the products. Recently both the USDA and the Food and Drug Administration(FDA) announced that they will begin jointly controlling the new “cell-based meat” category.
Many of us have concerns about the challenges facing future generations as our global population increases and the earth’s natural resources decreases. The good news is that there are plenty of businessmen around the world—like those producing lab-grown meats—who are working to solve some of these problems and make a little money in the process. Nothing wrong with that.
1.Why do some companies begin to develop new kinds of meats?
A.To analyse the causes of air pollution.
B.To stress the importance of protecting wild animals.
C.To make people less interested in eating meat and more healthy.
D.To meet people’s demand for meat in environmentally friendly ways.
2.What’s special about the lab-grown meats of Jet Eat?
A.They cost less. B.They are plant-based.
C.They are more delicious. D.They are available on the market now.
3.Which of the following is a barrier lab-grown meat industries must deal with?
A.How to let people accept the meat. B.How to give the meat an elegant name.
C.How to produce the meat in large amounts. D.How to reduce the cost of making the meat.
4.What’s the author’s attitude towards lab-grown meats?
A.Supportive. B.Opposing. C.Ambiguous. D.Cautious.
A 2018 report found that food waste would increase by a third to 2. 1billion tons by 2030. Beyond the cost of the waste itself，thrown-away food generates a gas that contributes to climate change.
Home delivery meal kits(盒)can reduce food waste by more than two-thirds，but suppliers need to switch to reusable packaging to make them environmentally friendly.
Tailor-made meal kits cut waste by providing people with precise amounts of fresh ingredients(烹饪原料)for chosen recipes，meaning leftovers are minimized. But while the delivery services score well on reducing food waste，buying the same food ingredients from the supermarket almost always saves energy overall simply because meal kits use so much single-use packaging. The good news is that if people have meals that are tailored for consumption，they won’t overbuy and have less food waste. They fine-tune the amount of food to what they will actually eat.
Meal kits can reduce transport emissions(排放)if people go to the supermarket less frequently. If people only go and buy such goods as soap and toilet paper，they may only have to visit once every couple of months. A delivery truck can carry meals for a lot of people in the neighborhood. So dozens of car trips might be replaced with one truck trip.
However，study found that even if delivery meal kits reduced food waste to zero，they would still use up more energy overall than buying the same food from the supermarket unless the energy used for the meal kit packaging was cut by a fifth. The packaging is a killer if it’s single-use and thrown away，which can make all the environmental benefits lost. But if the packaging can be reused，if it’s glass bottles，like in the old days，we can get some benefits.
