We all know that forests-especially rainforests-absorb carbon dioxide and produce the oxygen that all living things depend on. It’s no wonder that they have been named the lungs of the planet. Today, after the big fires in the Amazon, Alaska, Greenland, and even Siberia, it’s very clear that we need to grow a forest that is fireproof. That’s not an impossible dream. We can grow seaweed forests that are fireproof because they are underwater.
Seaweed can store carbon and help reduce the influence of global warming. Now, seaweed is being farmed in small ocean farms to be used for food, medicines, and beauty products. If seaweed can be grown on a large scale(大规模地), it could help to fight against global warming.
“Seaweed is finally having its moment in the spotlight,” said Halley Froehlich, a scientist at the University of California. She is the lead author of a new study published in Current Biology. The study shows that large-scale seaweed farming could be used to cancel out land-based carbon emissions and it mapped the areas of the oceans where seaweed could be grown.
Now, only 3.8 percent of the US waters off the coast of California are being used to grow seaweed but that is just 0.065 of the ocean that can be farmed. In fact, 48 square kilometers of the world’s oceans can be used for seaweed farming.
For seaweed farms to be part of the global solution, they will have to be much larger. To create underwater forests, seaweed would have to be grown, harvested and then sunk into the deep ocean so that the trapped carbon could be buried for years to come.
While it sounds like a good plan on paper, “The technology doesn’t yet exist” to keep seaweed in the deep ocean, said Froehlich. “Hopefully this paper encourages conversation among engineers and economists about what it would take for the actual tools to be put in place.”
1.What makes people put forward the idea of growing seaweed forests?
A.The burning of forests.
B.Seaweed’s economic and medical value.
C.Uncontrollable carbon dioxide emissions.
D.Their long-lasting dream of underwater exploration.
2.Why can seaweed be used to fight against global warming?
A.It doesn’t burn. B.It doesn’t pollute.
C.It can take in carbon. D.It can break down plastics.
3.What does the underlined part “having its moment in the spotlight”in Paragraph 4 probably mean?
A.Breaking silence. B.Taking a bad turn.
C.Drawing people’s attention. D.Making room for other products.
4.What does Frochlich say about the idea of growing seaweed forests in the last paragraph?
A.It has a long way to go. B.It has been put into practice.
C.It needs lots of money to carry out. D.It needs enough evidence to support.

In the case of vomiting（呕吐）during the race,and yes,there’s quite a bit of that during the Beer.Mile,offenders must complete one more lap at the end of the race.Organizers mention that even in the case of vomiting several times, only one more lap must be completed.
This year,the Elite Men's race was won by Canadian Corey Bellemore,who also set a new world record with a time of 4 minutes and 34 seconds.“I just drink the beers as quickly as I could,hold them down and get the burps（饱嗝）out,”Corey said.“If you can drink a beer in 8 seconds and also run very fast with a feeling of vomiting,then you’ll be fine like me.”

We all know that theme parks are places to have fun and amuse ourselves, but among so many exciting rides there are also some dangers. Make sure you know what the safety standards are for all the attractions at the park. If you do that, you will be safe and have fun.
Drink water. Believe it or not, dehydration—when your body doesn’t have enough water—is the commonest cause of injuries at theme parks. Drinking water while you are at the park is not enough. You must make sure that you drink enough water before your visit.
Use your “common sense”. There are lots of people around, so make sure where your friends or family are. Also, if you are walking and want to stop, make sure nobody is walking behind you. First step aside, then look behind and if you aren’t in anybody’s way, then stop. It might sound exaggerated(夸张的), but crashes between people can cause accidents.
Follow the instructions. The majority of theme parks have instructions for each ride. Some rides only allow people of a certain height. So make sure you are not too tall or too short before boarding any ride. Also, people with certain diseases or conditions are advised not to go on some rides. Do remember: If you are told not to go on a ride, then DON’T.
Do not ride with a bad stomach or if you’ve just eaten. Rides can make you ill because of their violent changes of direction and your lunch may end up on someone else’s head: surely not a very pleasant experience.
Have fun, relax, and be a little brave!
Some rides might look scary but theme parks are very safe places.
1.What is the leading reason for injuries at theme parks?
A.snow B.dehydration
C.fire D.crashes
2.Which of the following will the author accept?
A.Children should not play in theme parks.

C.One must always stay with his friends or family in theme parks.
D.One must read the instructions before playing in theme parks.
3.According to the author,____.
