21、Wearing a face mask will keep you and others safer when you have to leave the house. 【1】. But the bad news is that you now realize you suffer from unpleasant smells. Here are four ways to combat bad breath and make wearing a mask a more pleasant experience.
●Keep away from certain foods
Onions and garlic not only add flavor to many foods but also add smells that are not easily brushed away. The substances that cause their bad smells make their way into your bloodstream and travel to your lungs, where you breathe them out. 【2】.
● 【3】
Saliva (唾液) is the key ingredient in your mouth that helps keep the smell under control because it helps wash away food particles and bacteria. If you are not producing much saliva, try drinking water or chewing sugarless gum.
●Brush your teeth
You’d better brush your teeth at least twice a day to reduce harmful bacteria on your teeth. The sticky buildup on your teeth collects bacteria that cause bad breath, and trapped food adds to the problem. 【4】. It is proved that if you brush too hard, you can wear down your teeth, making them vulnerable to decay.
●Brush your tongue
【5】. It can end up on your tongue. To rid your tongue of smell—causing bacteria, remember to brush it when you clean your teeth. If your toothbrush is too big to reach the back of your tongue, buy a tool used for removing the accumulation.
A.Avoid dry mouth
B.Wash your hands
C.That’s the good news
D.Buy a proper toothbrush instead
E.Bacteria don’t just live on your teeth
F.But the experts warn against overdoing it.
G.Avoiding those foods is the best way to get rid of the problem
22、Vaccines(疫苗) may soon make their first film appearance. Led by expert Maria A. Croyle, researchers have developed a thin sheet that preserves vaccines for long periods without refrigeration. This means the carefully cooled small bottles now used to ship vaccines could potentially be replaced by lightweight films that can be mailed in an envelope and stored on a shelf.
Croyle’s laboratory began developing the technology in 2007. Inspired by amber’s ability to preserve the DNA of insects, the researchers set out to create their own version of the substance by mixing “a lot of sugar and a little bit of salt, much like hard candy,” Croyle explains. The vaccine-containing film is administered by mouth—sweet news for many who dislike needles.
The film is tailored to suit each specific vaccine candidate and provide a protective coating. “We’ve learned over time that the key to really stabilizing whatever the film holds is to have it intermixed with all the components,” Croyle says, adding that the process is quick and uses affordable, standard equipment. “We really wanted to come up with something that would be transferable to developing countries.”
Immunization(免疫) programs depend heavily on keeping vaccines cold(2℃-8℃) as they are transported, sometimes over thousands of kilometers to far-away locations. Delivery can be difficult and costly, and transport disruptions can cause the vaccines to be ineffective.
But this new product can store live viruses, bacteria and antibodies for several months at 20℃. In a paper published in Science Advances, the scientists show that the live viruses in one vaccine were preserved in the film even after 36 months. They also find that a flu vaccine suspended in their film compares favourably with a traditional flu shot(流感预防针). “The study demonstrates early proof of concept for an exciting platform for vaccine product development,” says Lisa Rohan, a pharmacologist, who was not involved in the study. She also notes that each vaccine type would need a custom formulation(配方) for future stages of development.
Finding partners to mass-produce for clinical trials is the researchers’ most pressing problem, Croyle says. They are also exploring packaging methods to keep their films stable up to 40℃.
Size is a major advantage—a letter-sized sheet of the film can carry more than 500 doses(剂) of vaccine, about 1⁄900 the weight of the same amount of traditional doses. By making it easier and cheaper to ship and preserve vaccines efficiently, Croyle says, the technology could vastly improve immunization rates the world over, particularly in middle- to low- income countries.
【1】What can we learn about the film?
A.It contains animal’s DNA.
B.It will replace vaccines.
C.It comes in different flavours.
D.It can hold bio-products.
【2】According to Paragraph 3, we can learn about the film’s ________.

D.transportation requirements
【3】The author mentions Lisa Rohan’s words to ________.
A.advise personalizing vaccines
B.suggest the product is promising
C.prove the study is supported widely
D.stress the functions of a new platform
【4】What will be the next urgent task for Croyle’s team?
A.Advertising the film worldwide.
B.Improving the film’s capacity.

Pesticides might just be a bee's worst enemy. They harm their brains, slow down their reproduction, and even kill their buzz. Now it seems they damage their social lives and reduce their ability to care for their young.
While previous studies have shown that commonly used neonicotinoid(新烟碱类)pesticides make bees sick and affect how they search for food and navigate, a new study gives more of an idea of how these chemicals affect the internal workings of a colony(种群). Studying these effects has proved difficult, so the team employed a new technique. They stuck tiny QR codes to the backs of humblebees and tracked their movements using a robotic camera.
The researchers looked at 12 colonies housed in a lab, giving some the same level of imidacloprid—the world's most commonly used pesticide—that they'd be exposed to in the wild while keeping others pesticide-free as controls. They checked on them for a few minutes 12 times a day. The findings are published in the journal Science.
Unfortunately, the researchers found a number of obvious differences between the bees exposed to the pesticide and the controls. The bees given neonicotinoids spent less time interacting with other bees and more time resting. This pause in activity tended to happen more at night, but the researchers aren't sure why.
"Bees actually have a very strong circadian rhythm(生理节奏)," lead author James Crall explained in a statement. "So what we found was that, during the day, there was no statistically observable effect, but at night, we could see that they were crashing. We don't know yet whether the pesticides are destroying circadian gene regulation or if this is just some, maybe physiological feedback…But it suggests that, just from a practical perspective, if we want to understand or study these compounds, looking at effects overnight matters a lot."
【1】What does the new study suggest about pesticides' effect on bees?
A.Pesticides lead to their disease.
B.Pesticides slow down their brain function
C.Pesticides upset their community.
D.Pesticides damage bees' internal parts.
【2】What does the underlined word "controls" in Paragraph 3 refer to?
A.The tools used to observe the bees.
B.The data recorded by the robotic camera
C.The researchers conducting the experiments.
D.The bees kept free from the pesticides.
【3】What can be concluded from the last paragraph?
A.The circadian rhythm of bees is stronger during the day.
B.It is vital to study the performance of bees at night
C.It is certain that pesticides affect bees only at night.
D.The pesticides do great harm to circadian gene regulation of bees.
【4】What's the purpose of the passage?
A.To inform people of the worrying effects of pesticides.
B.To check the best time to observe experimental results.
C.To call for the toughest ban on the chemicals.
D.To recommend measures to improve the quality of pesticides.
24、Since the beginning of time never has there been another with my mind, my heart, my eyes, my ears, my hands, my mouth. None that came before, none that live today, and none that come tomorrow can walk and talk and move and think exactly like me. I’m a unique creature.
Vain attempts to imitate others no longer will I make. Instead will I place my uniqueness on display in the market place. I will begin now to highlight my differences; hide my similarities.
I am rare, and therefore I am valuable. I am the end product of thousands of years of evolution; therefore, I am better equipped in both mind and body than all the emperors and wise men before me.
But my skills, my mind, my heart, and my body will weaken, rot, and die for fear that I put them to good use. I have unlimited potential. Only a tiny part of my brain do I employ; only a small amount of my muscle do I apply.
So never again will I be satisfied with yesterday's accomplishments nor will I lose myself, anymore, in self-praise for deeds which in reality are too small to even acknowledge. I can accomplish far more than I have, and I will. I am not on this earth by chance. I am here for a purpose and that purpose is to grow into a mountain, not to shrink to a grain of sand. Henceforth(从今往后) will I apply all my efforts to become the highest mountain of all and I will strain my potential until it cries for mercy.
I will increase my knowledge of mankind, myself, and the goods I sell. I will practice, and improve, and polish the words I speak to multiply my sales, for this is the foundation on which I will build my career. Also will I seek constantly to improve my manners and graces, for they are the sugar to which all are attracted.
I have been given eyes to see and a mind to think and now I know a great secret of life that all my problems, discouragements, and heartaches are, in truth, great opportunities in disguise. I am nature’s greatest miracle. And nature knows not defeat. Eventually, she achieves victory and so will I, and with each victory the next struggle becomes less difficult.
