3 . Sunflowers have increasingly become popular on social media. People enjoy the bright yellow flowers and take pictures of themselves in bright fields of sunflowers, which are called “sunflower selfies.”
Actually, it is easy to grow your own sunflowers. Here are some instructions.
Do you want to start growing sunflowers from seeds?
Then, plant each seed into soil apart. Keep the soil wet, but not too wet, until the seeds begin to grow. During the growth process, you should water regularly the plants. When they grow up, it is best to put up some shelves to protect the plants from strong winds.
When seeds will start coming out of the head, it is time for harvest. Cut the flowers off and put them into a bag or container. In this way, the seeds will not fall out. Then remove the seeds by rubbing flowers with your hands or a hard brush over a container.
Finally, you’d better select those full seeds for food.
A.Equally attractive is the delicious taste. |
B.Sunflower seeds may be eaten cooked or uncooked. |
C.You can also tie the plants to something tall for support. |
D.Some kinds of sunflowers can grow up to three meters tall. |
E.It is important to loosen the soil before the seeds are planted. |
F.Put the selected seeds in room-temperature water for 2-8 hours. |
G.They will develop long roots that work their way deep into the ground. |

6 . Want to reduce your risk for dementia (痴呆)? Turn on a step counter and start counting your steps — you’ll need between 3,800 and 9,800 each day to reduce your risk of mental decline, according to a new study.
People between the ages of 40 and 79 who took 9,826 steps per day were 50% less likely to develop dementia within seven years, the study found. Furthermore, people who walked with “purpose” — at a pace over 40 steps a minute — were able to cut their risk of dementia by 57% with just 6,315 steps a day.
Even people who walked approximately 3,800 steps a day at any speed cut their risk of dementia by 25%, the study also showed.
“That would be enough, at first, for sedentary (久坐不动的) individuals,” said study coauthor Borja del Pozo Cruz, a senior researcher in health sciences for the University of Cadiz. in Spain, in an email. “In fact, it is a message that doctors could use to motivate very sedentary older adults — 4,000 steps is very achievable by many, even those that are less fit or do not feel very motivated.” he added. “Perhaps, more active and fitter individuals should aim for 10,000 steps, where we see maximum effects.”
But there was a even more interesting result buried in the study, according to an editorial (社论) entitled “Is 112 the New 10,000?” published Tuesday in JAMA Neurology.
The largest reduction in dementia risk — 62% — was achieved by people who walked at a very brisk pace of 112 steps per minute for 30 minutes a day, the study found. Prior research has labeled 100 steps a minute (2.7 miles per hour) as a “quick and energetic” or moderate level of intensity.
The editorial argued that individuals looking to reduce their risk of dementia focus on their walking pace over their walked distance.
“We do agree this is a very interesting finding,” said del Pozo Cruz via email. “Our take is that intensity of stepping matters! Over and above volume. Technology could be used to track not only number of steps but also pace and so these types of metrics can also be included in commercial watches. More research is needed on this.”

7 . Are you a tea drinker? If so, you’re not alone. Every day around the world millions of cups of this popular brew (沏茶) are drunk. The oldest discovered tea is from the Han Dynasty. But the tea trend really took off during the Tang Dynasty, when it became China’s national drink.
Tea is the second most consumed drink in the world. Most of us can’t resist a cup of tea sometimes. They’re a perfect pick-me-up and comforter. For many, having a “cuppa” is a daily routine. And according to some scientists, habitual tea consumption can have some health benefits. Drinking black tea may speed up recovery from the daily stresses in life, though we do not know what ingredients of tea take effect. Also, drinking seven or more cups of green tea was associated with a lower risk of death among both heart attack and stroke survivors. So, if we turn to tea for its taste, its image or as a lifestyle choice, it could be a lifesaver!
Tea is consumed in many ways — slurped, sipped or glugged (大口喝). It can be poured from pots, infused or brewed in the cup using tea bags — and it’s this latter process that is causing concern. Scientists from McGill University in Montreal found that some ‘plastic’ tea bags shed high levels of microplastics into water. However, The World Health Organization says such particles in drinking water do not appear to pose a risk.
Most tea bags are made from paper, with a small amount of plastic used to seal them shut. This has led to debate about whether they can be recycled. However, gardener Mike Armitage has said that the plastic contained in the soil could be washed into streams and rivers and ultimately out to sea.
Unilever, the owners of the tea brand PG Tips, said their tea bags are made with a small amount of plastic-used to seal them-and that they are suitable for composting. And the brand Yorkshire Tea said their bags do contain plastic, but they were actively developing recyclable things to replace the plastic.
