If you ever wanted to have insight (领悟) into how you can succeed in school, you’re in luck. Here are some tips to help you succeed this school year. They are provided by teachers and administrators (管理者) who work in schools on Long Island, New York, the US.
Use a calendar or chart. “Hang a calendar on your refrigerator”, said Margarita a teacher from Jackson Avenue School. She suggested writing down special assignments, birthdays, events and activities to help you remember. You can also draw a heart or other shapes on the joyful days you have spent
A book is a treat. Visit the bookstore or library every few weeks to find a new book to read on your own, recommended Lori, a teacher at Summit Lane School. “The more kids get excited about reading on their own, the more their self-esteem (自信) will rise. They’ll also be better equipped to deal with challenging homework assignments.” The ability of finishing reading a book is acquired by practising reading before one becomes a grown-up.
Unplug for success. “Families should have a no-electronics (电子产品) period where everyone turns off their devices (设备),” said Angela English teacher at Wisdom Lane Middle School. “This way family members can spend time together playing games. It’s amazing how you can reconnect with yourself and others when you're not distracted by technology.” Not to mention that it can also do good to your neck, shoulders and spine.
Stay current. “Stay up-to-date on current events,” said Matthew Crichton, a social studies teacher in New York. “Take a current events article and look at the history of the event. Knowing more about the world benefits a lot.”

The Science magazine reported that scientists had successfully grown meat in their laboratory by November, 2018. The news aroused heated discussion among the public. Is the meat safe? Is it any different? Why do we have to grow meat in a lab? People have tons of questions about this. And the scientists said that the lab-grown meat is produced when cells from animals are grown under lab conditions. It isn't like plant-based meat substitutes (替代品) made from vegetable proteins (蛋白质), since cell-based meat is grown from actual animal cells. This means that it is an animal product, so not suitable for vegetarians.
Is cell-cultured meat the same as ordinary meat? The muscle fibers (纤维) produced in the lab are the same as those found in steak, said leading researchers in this technology at Maastricht University in The Netherlands. But they pointed out that to get the same nutrient. (营养物) content that is found in red meat, they need to make some changes to the procedure. Scientists say they are also looking into changing the type of fat in lab-grown meat, for example.
Some people have concerns with growing meat in the lab. Some say this method of meat production would result in less land and water use. Others argue that growing meat in the lab would influence the environment more negatively than our traditional way of raising cattle. It would take massive amounts of energy resources to produce meat in this way, they say.
Some groups have petitioned (请求) the US Food and Drug Administration (FDA) to better define the term “meat”. They want to know if we are buying the traditionally produced type or the cultured variety. Hopefully we will see some labeling guidelines on these products before they show up in grocery stores. And that may be a few years away. Regulatory issues and cost - the first lab-grown hamburger patty (肉饼) cost $330,000 (2274,900 yuan) - could delay the arrival of cultured meat.

2.According to the passage, the lab-grown meat ______.
A.is the same as ordinary meat

A.the US FDA feels it necessary to label different kinds of meat
B.grocery stores have already been selling cultured meat to the public
