Summer is the season of mosquitoes. And mosquito bites are truly the worst-not only are they huge and painful, but they itch(发痒) like nothing else. And once you start scratching (挠), it’s hard to stop.
You can blame female mosquitoes for the trouble we all face. There is something that enters the skin while the mosquito is enjoying its blood meal. This is the protein that leads to the allergic reaction and itching. Basically, our immune systems see the protein as an enemy. This causes the local reaction we see as the bug bite. Our bodies are just particularly sensitive to mosquito bites. Other bug bites may not have the same effect on your immune system. Bees for example, are likely to produce more pain than an itch.
Scratching a mosquito bite is a double-edged sword. It feels so good, but it also makes the itch way worse. When you scratch, you may release more local histamine, the chemical in the skin that causes the itching, and you may also be spreading the allergen under the skin. If you tend to scratch until you bleed you’re putting yourself at risk for skin infections.
You’re not imagining it -mosquito bites do itch more at night. Most people itch more at night because we are less distracted as we try to fall asleep.
If you’ve ever wondered why some mosquito bites itch more than others, it totally depends on your body. Everyone responds differently to mosquito bites. While some people may have a minimal reaction, others may experience serious reaction. It just depends on your body’s immune system. People with so-called atopic traits, who are highly sensitive, are more likely to develop more serious local reactions after the mosquito bites.

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.”

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?

One piece of advice I give young people is that they don't have to decide what they want to do for the rest of their life at age 22. Just think of all the jobs that didn’t exist 10 years ago and what might exist 10 years from now.
My daughter is a nurse practitioner(从业者). But she didn’t start there when she went to college. She got her undergraduate degree in hotel and restaurant management with a minor(辅修课程) in business. She wanted to find a job in travel and tourism and see the world. On graduation day she looked at me and said, “Mom, I don’t know what I’m going to do with my life that’s meaningful, but I don’t think it' s travel and tourism”. I looked at her and said, “Just get a job and then figure it out.”
She struggled for a year or two after college with a couple of different jobs including work in the travel industry for a short time. But she started thinking early on after graduation about becoming a nurse. Whenever she talked to me about it, I told her she’d be a great nurse-super organized, able to multitask better than anyone I knew, with amazing people skills. But I also told her that she’d have to work hard and study the sciences if she wanted to be a nurse.
She considered her choices and decided to enter a combined nursing/nurse practitioner program getting her second bachelor’s degree then her master’s. She had found her passion(热衷的爱好)!Her nursing career since 2005 has progressed. She now has a mix of leadership, administrative, and clinical work.
Do you know what your passion is? Have you found it in your work or are you still searching for it?

Last Sunday, I went to Tian'anmen Square with my cousin, a boy of nine year old. Because it was the first time that he has come to Beijing, so everything could interest him. He took many photos, saying they would be showing to his friends, most of who had never visited Beijing. Then a foreigner in the fifties caught our attention. To my greatly surprise, before I could react, my cousin went up. With fluent English, he asked if she needed any help. Knowing her passport missing, we immediately helped her got in touch with the police. What a kind boy!
