These are the most useful words, or the common words, words that form core of the English vocabulary. They are the words we must learn and remember.

___21___. A study recently published in Current Biology reflects previous perspective. Can you catch up on lost sleep? Here’s what the science says.
Losing even an hour puts you in sleep debt.
___22___: Withdraw an hour on Monday, then deposit an extra one on Saturday to break even. But as far as truly making up for the lost sleep during the week, you really can’t make up for it hour by hour. Research has suggested that a person would actually need four days of adequate rest to make up for even one hour of sleep debt. ___23___, it’s almost mathematically impossible to close that gap over only two weekend nights.
Your circadian clock (生物钟) is more sensitive than you think.
Pulling an occasional all-nighter or extra-early morning may not seem like a big deal. But tiredness isn’t the only consequence of an uncertain sleep schedule. ___24___. Your circadian clock naturally starts producing sleep-promoting melatonin (褪黑素) around 9 p.m., and levels stay high throughout the night before dropping off in the morning. Light exposure influences circadian rhythms somewhat—which is why you may have trouble sleeping after using screens at night—but if you maintain stable sleep and wake times, your internal clock should be similarly reliable.
___25___.
If you’re exhausted by the time Saturday arrives, you should select a midday nap rather than a marathon overnight sleep. Previous research has also linked naps to better, memory focus and creativity. The National Sleep Foundation says that just 20 minutes of napping is enough to leave you feeling refreshed, as long as you don’t nap too close to bedtime.
A．Napping is better than sleeping in
B．Many people think of sleep like a bank account
C．If you spend that extra time sleeping during the week
D．Since many people get less sleep than they need just about every weeknight

G．It also disrupts your circadian clock, a system that regulates hormone levels to promote sleep

Researchers recently discovered that mosquitoes who have their sleep disrupted would rather get rest than go looking for their next meal. “____26____. Sleep deprived (睡眠不足) or not, a blood meal should appeal to them.” said the lead author of the study.
To study mosquitoes, researchers spent more than a year developing ways to analyze and quantify their amount of sleep. It was particularly challenging because of something researchers call the “observer effect”.____27____. In the case of mosquitoes, they’re able to sense that people are nearby due to their body heat, movement, smells and breath.
To deal with those circumstances, researchers set up the experiment in a quiet lab where the mosquitoes were several rooms away from anybody who might pass by. ____28____. Researchers found that the mosquitoes in the lab slept between 16 and 19 hours each day. They moved their enclosures regularly at night or during the day to make them suffer sleep deprivation. ____29____. But less than one-quarter wanted to eat after asleep less night.
____30____. By understanding the circadian rhythms of insects, researchers hope to find new methods to prevent the spread of infections. In fruit flies, a link between sleep and immunity (免疫力) has been established. And immunity is an important factor for disease transmission in mosquitoes. Based on this, this research would provide us with an understanding of the role of sleep on the disease transmission in mosquitoes.
A．That was so natural
B．It was a bit surprising
C．Mosquitoes can spread serious diseases to humans
D．They placed cameras and sensors in the room to record the mosquitoes without disturbing them

And it will often turn into much more than five minutes.

Is there something you can do about it? There sure is. ____57____ .
First, reduce. Something simple like turning off the lights when you leave a room or turning off the water faucet while you brush your teeth can make a big difference.   ____58____ , and even using a cloth towel rather than a paper towel when you spill something in the kitchen can help our planet.
When you don’t want a toy you have anymore, don’t just throw it away. Find a friend who might want it. That is reusing. Clothes you have grown out of can be donated for others to wear. A plastic cup you drank out of can be cleaned and used to store small toys in your room.   ____59____
____60____ . Look on the bottom of plastic cups and containers. If you see a recyclable symbol, you can recycle the item. Newspapers, school papers, even glass jars and bottles can be recycled.

For a greater chance of success, your plan should have a deadline and it must be measurable. ____62____ Give yourself the gift of setting a deadline and things will start to happen.

One of the most popular new outdoor activities is day hiking. For many first-time hikers, it’s important to learn the proper hiking tips and safety rules. ____96____ Here are some of the main ones to know.
Take out your own garbage. One of the biggest surprises for people new to the outdoors is that many parks and trails have no facilities; i.e., no restrooms or garbage cans. ____97____ You’re even supposed to ferry out poop (your own or your pet’s), unless you bury it 200 feet from the trail or any water source. Advisably, you can pack out trash with some zip top bags.
Don’t move things around. This means no taking home pretty rocks or flowers. Any time you move or remove something, you may destroy an animal s home or a weak ecosystem. Leaving things alone also applies to wildlife, so don’t try to pet a deer or approach a bear for a great photo. ____98____
____99____Since hikers tend to head into the outdoors to enjoy all of the natural sights, sounds and smells, don’t blast music, talk loudly on the phone or bring along an uncontrolled pet. Being a considerate hiker also helps the resident wildlife, which may need undisturbed spaces and enough quiet to hear the sounds of nature for their communication and survival.
Know when to stay on and step off the trail. Hiking trails are created with specific purposes, which may include preventing pollution to environment and protecting precious plant and animal communities. ____100____ There are a few exceptions, such as leaving the trail to “use the restroom”.
A．Enjoy them from a safe distance.
B．Be considerate of your fellow hikers.
C．So stay on the trail as much as possible.
D．Communicate with other hikers politely.
E．That means you’re supposed to carry back out whatever you bring in.
F．Just as with any sport or activity, hiking involves certain accepted practices.
G．It’s also considered proper to step off the trail if you want to rest or have a snack.
