Supermarket shelves are filled with plant-based alternatives to cow milk, including soy, nut, and coconut milk. These products are popular with consumers who cannot drink cows’ milk for health reasons, as well as with those concerned about animal welfare and environmental sustainability. While the dairy-free(非乳制的) options work well with cereal or in coffee, they fail miserably when it comes to making milk-based products like cheese or yogurt. However, these shortcomings may soon be a thing of the past, thanks to a new company in California, which has figured out how to create animal-free milk in a laboratory!
Perumal Gandhi and Ryan Pandya founded the company in 2014 after becoming increasingly annoyed with the lack of cows’ milk-free alternatives, particularly for cheese. For Gandhi, who stopped consuming animal products five years earlier due to environmental and animal welfare concerns, the motivation to create a better alternative stemmed from his love of cheesy pizza. Pandya was spurred into taking action after being forced to eat some “really bad” dairy-free cream cheese on his sandwich
The two MIT biomedical engineering scientists decided to join forces to create a more realistic alternative to dairy-based products. In their university lab, the pair spent nine months first isolating cow DNA then inserting it into yeast(酵母). This genetic modification enabled the yeast to produce the necessary milk proteins. The final step of the process involved mixing the proteins with some plant nutrients and fats.
The dairy-free milk not only tastes like the real thing but is also healthier, has a longer shelf life and, most important of all, is Earth friendly. According to the company’s website, when compared to conventional milk production, their process uses 65% less energy, creates 84%o less greenhouse gas emissions and requires 91% less land and an amazing 98% less water! Best of all, since it contains real milk proteins, the product behaves like the cow-produced version, which means vegetarian consumers will no longer have to deal with soggy cheese on their sandwiches and pizzas.
The company plans to bring their creation to market later this year and their first product will most likely be cheese since there are already numerous good cows’ milk alternatives available to consumers.
1.The underlined word "those" in paragraph 1 refers to_______.
A. alternatives B. people
C. products D. reasons
2.The company s founders were motivated to make the new product because of_______.
A. their deep concern for the environment
B. their worry that farm animals were poorly treated
C. the over-consumption of the dairy-based products
D. the poor taste of dairy-free cheese presently available

B. The new products will taste better than dairy-based ones.
C. Cow farming causes considerable environmental damage.
D. The dairy-free milk will be more expensive than cow’s milk.

As skies are filled with millions of migrating(迁徙) birds, European scientists say the seasonal wonder appears to be strange. The fatter the bird, the better it flies.
The results of their study led to a theory opposite to a central one of aerodynamics(空气动力学), which says that the power needed to fly increases with weight.
For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think. Researchers found that red knot wading birds double their normal body weight of 100 grams before making their twice-a-year nonstop flight between the British Isles and the Russian Arctic.Distance;5,000 kilometers.
Another study in the magazine Nature measured the advantage of flying in an aerodynamic group which allows birds to save energy by flying smoothly and quietly in the lead bird’s air stream.
Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri, a French scientist. The findings help explain how birds complete difficult migrations. Researchers had thought stronger birds would have the best chance to survive.
The first study suggests that building up fat to be burnt as fuel during the migration is worth more than the energy it take to carry the additional weight.
In the study, researchers said their team studied the birds flown at different body weights during 28 simulated(模拟的)flights. They forced a small amount of special water into the birds’ bodies so that they could measure the amount of energy burnt during the flight.
1.A red knot wading bird of 100 grams will probably weigh ________before making its nonstop migrating flight.
A.50 grams B.100 grams C.150 grams D.200 grams
2.During their migrating flight, red knot wading birds can save energy by flying________.
A. separately B. alone C. in groups D. in pairs
3.A ________red knot wading bird has a better chance to survive during its migrating flight.
A. stronger B. weaker C. thinner D. fatter
4.The best title for this passage may probably be ________ .
A. Birds Thin Down For Journey B. Birds Fatten Up For Journey
C. How Birds Build Up Fat For Journey D. How Birds Burn Energy For Journey

Concepts from science and nature are filled with our language’s common phrases , idioms and spoken expressions. The unbelieving expression “Well, I’ll be a monkey’s uncle” has its origin in bitter disbelief over Darwin’s writings on evolution. These colourful expressions bring spice(趣味) to our language.
Yet certain well-used phrases from science are just plain wrong! Some are obvious, yet we use them anyhow. For example, a person who acutely shakes her head and says “ A watched pot never boils” while you are waiting second after tiring second for test results to arrive or job offers to come in knows that if she sat down and watched a pot containing water on a stove over high heat for long enough, the water will eventually boil.
However, a few phrases have less obvious scientific inaccuracies. Here are a few for you to consider.
Once in a blue moon: This poetic phrase refers to something that occurs extremely rarely. A blue moon is the term commonly used for a second full moon that occasionally appears in a single month of our solar-based calendars. The problem with the phrase, however, is that blue moons are not so rare. They happen every few years at least, and can even happen within months of each other when the 29.5-day lunar cycle puts the full moon at the beginning of any month but February. The usage of “blue moon” as the second full moon in a month dates back to a 1937 Marine Farmer’s Almanac . But before that, blue moons meant something slightly different. Typically, 12 full moons occur from winter solstice to the next winter solstice, but occasionally a fourth full moon in a season could be observed . In such a case, one of the four full moons in that season was known as “blue”
Where there’s smoke, there’s fire: The phrase means that if something looks wrong, it likely is wrong. But let’s step back. Do you always have to have fire if you see smoke? Answering that first requires defining ‘fire” , Merriam—Webster’s first definition of fire is “ the phenomenon of combustion manifested in light, flame and heat”. Combustion is the chemical reaction that occurs when fuel is burned in the presence of oxygen---denying a fire any of these three things will stop the fire; attempting to start a fire without any one of the three things will be impossible. In complete combustion---what occurs when you light a gas stove--- the fire produces no smoke. However, when most materials are burned, they have incomplete combustion, which means that the fire isn’t able to completely burn all of the fuel . Smoke, then, can be considered to be a product of pyrolysis (高温分解) rather than of fire itself. You’re probably thinking---so what? To get the smoke, a fire needed to be present at some point, right? Not always.
Diamonds are forever: Thanks to the DeBeers slogan , decorating your honey’s neck, wrists and fingers with diamonds means true and timeless love. Of course, no object that you can hold in your hand can last forever. But diamonds have a special reason for being incapable of timelessness. Without the extreme pressures of the deep Earth where they formed, a diamond will slowly turn back into graphite(石墨), which is why the older a diamond is, the more inclusions it’s likely to have.
What common phrases push your buttons when viewed under the microscope of science? Are you curious about the hidden knowledge of some “ big” phrases ? Or perhaps you have the ability to uncover the secret of some unscientific phrases? Let us know!
1.According to the passage, the blue moon _________.
A. appears at the beginning of a month
B. gains its modern meaning before 1937
C. presents itself quite frequently sometimes
D. can never be seen by people in February
2.What can be concluded from the passage?
A. the older a diamond is, the more valuable it’s likely to be.
B. Fire is not necessarily causing smoke
C. Smoke is a product of complete combustion
D. the less obvious scientific inaccuracies of some phrases make them more useful
3. The underlined phrase “push your buttons” in the last paragraph means “_______”.
A. impress you a lot B. frighten you much.
C. surprise you greatly D. make you lose your interest
4. The author’s attitude towards the scientific inaccuracies of the phrases is ________.
A. indifferent B. objective
C. critical D. favourable
