【推荐1】Homemade lemonade goes great with outdoor spring and summer entertaining. Follow the instructions to serve at your next picnic or barbecue.
After the lemons have been warmed, roll them on a solid surface. Keep rolling until you feel the flesh softening. After rolling the lemons, cut them in half crosswise. Place one half of the lemon on the juicer, apply pressure and twist the lemon to remove the juice.
Remove all the seeds from the juicer once you have finished. The extra pulp（果浆）that has collected in the bottom of the juicer can be added to the lemon juice once the seeds have been removed, unless pulp-free juice is required. If it is necessary to use pulp-free juice, strain juice to separate any pulp that may have gotten into the juice.
In a saucepan, bring 
cup of water to a boil and then add 
cup of sugar. Continue to cook over medium low heat until sugar has completely dissolved.

(1.) Keep a Positive Attitude. Enjoy what you have and work on getting the things you desire. Psychologists believe that optimism (乐观主义) is a good defense against unhappiness, so it is better to keep your optimism alive. Feeling sad about your life will only make you sadder, so be happy.
(2.) Don’t Be Afraid to Take Risks. Life is all about taking risks, and that’s the exciting part of it. Challenges and failure are part of life. Once you learn how to take risks, you’ll soon realize how good it feels not to let moments pass you by.
(3)
(4.) List the Things You Want to Do. Stop lazing around and give yourself something to be busy with. Write down a list of all the things you want to do and make a timeline, not to stress you out, but to remind you of your goals. So don’t put limits to yourself because you’ll never know what may happen.
(5.) Try Out Something New. Getting into something or trying something unfamiliar to you may seem scary, but nothing can make you feel happier than being able to overcome your fear. Who knows? You might enjoy it! The world is a big place and there are still lots of things waiting to be explored by you. Go to a foreign place where you know no one.

【推荐1】In October, Medflies (地中海果蝇) were discovered in an area of Los Angeles. California is a big farming state, and this was serious news for farmers. The solution to the problem may seem a little unusual; releasing (释放) millions more of the Medflies. Medflies lay their eggs in over 300 kinds of fruits and vegetables. When the eggs hatch (孵化), they can ruin these fruits and vegetables. The problem is that it can be hard to know that the Medflies are there until it’s too late. That’s because the fruits and vegetables still look normal even after the eggs are laid inside. So the damaged fruits and vegetables can be sent to other places allowing the Medflies to spread.
Three Medflies were discovered in a Los Angeles neighborhood called Leimert Park in October. The government set up a large quarantine (隔离) area, which means that no produce can be moved out of that area. That may seen extreme, since only three Medflies were found. but experts believe there are probably more out there.
Luckily, California has developed a program to control Medflies, and it has been working well for 30 years, The plan is to use planes to drop millions of male Medflies over the area. That may sound like a bad idea, but it’s actually a good way to make sure that Medfly numbers go down. Those Medflies are treated so that they can’t help produce new Medflies. This means that even though they can mate with female Medflies, the eggs produced will never grow or hatch.
The government says that the number of infestations (times when Medflies are found) has been cut by over 90%. To deal with the problem in Leimert Park, the government will be dropping two airplane loads of such Medflies every week.

【推荐2】Half of the world’s coral reefs have died in the last 30 years. Now scientists are racing to ensure that the rest will survive.
“The threat to coral reefs isn’t something that’s going to happen 100 years from now. We’re losing them right now,” Julia Baum told the Associated Press. She is a marine biologist at the University of Victoria, in British Columbia, Canada. “We’re losing them really quickly, much more quickly than I think any of us ever could have imagined.”
Even if global warming were in stop right now, scientists predict that more than 90% of corals will die by 2050. If no major steps are taken to address the issue, the reefs may be headed for total extinction.
The planet’s health depends on the survival of coral reefs. They are often described as underwater rainforests, because they are ecosystems that provide habitats for one in four of all marine species. In addition, the reefs serve as barriers that protect coastlines from the full force of powerful storms. Corals are used in medical research for cures to diseases. They are key to local economies, as well, since the reefs attract tourists, the fishing industry, and other businesses, bringing in billions of dollars of revenue (收入).
“To lose coral reefs is to fundamentally damage the health of the human race,” Ruth Gates, director of the Hawaii Institute of Marine Biology, said.
Corals are animals that lack a backbone. They live mostly in tropical waters. The corals release a substance called calcium carbonate (碳酸钙), which forms protective skeletons around them. The skeletons grow and take on vivid colors. This is the result of the corals’ mutually beneficial relationship with algae (藻类) that live in their tissues (组织) and give them energy.
But corals are particularly sensitive to changes in temperature. A rise of just 1 to 2 degrees Celsius can force the corals to drive out the algae. Then the corals’ skeletons turn white in a process called “bleaching”. Corals can survive in these higher temperatures only for a few months.

【推荐3】According to reports, three-quarters of all crops around the world depend on pollinating (授粉的) insects like bees and butterflies. By pollinating, pollinators enable the production of seeds. Without them, crop farming can become extremely difficult or costly threatening food supplies and prices globally.
Research has shown a rapid and consistent decline in pollinator populations. Average butterfly populations have almost halved since 1991 and bee populations in particular face a sharp decline. Given the world’s growing dependence on these insects, we can only expect the problem to worsen if no action is taken.
Much has been written about how intensive farming practices the use of chemical pesticides (杀虫剂), and pollution are threatening the survival of these helpful insects. To add to the already critical situation, global warming is contributing significantly to the rapid disappearance of pollinators.
Climate change is a major threat to pollinators, with rising temperatures and increasing frequency and intensity of extreme weather events affecting the food sources and habitats, on which pollinators depend for their survival.
Climate change also changes the timing and availability of lowering plants, leading to mismatches between pollinators and their food sources. A study has found that climate change has shifted plants’ blooming to earlier times and caused certain plants to move to higher areas, resulting in a decline in pollination.
Another study has found that climate change could lead to a decline in the quality of nectar, which is the main food source for many pollinators. As temperatures rise, the sugar content of nectar decreases, making it less nutritious for pollinators. This leads to a decline in the health and reproductive success of pollinators, as well as a decline in the pollination of plants.
Needless to say, cutting global emissions (排放量) is key. It’s essential that we continue to advocate for emission reductions. From country-level to individual businesses, more concrete roadmaps to net zero are a must.
We must at least minimize, if not prevent, the usage of pesticides, since these chemicals are harmful to pollinators and can have a far-reaching effect on pollination as a whole.
