26、 Supermarket shelves are filled with plant-based alternatives (可代替品) 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 (被激发) to take 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 (分离) cow DNA then inserting it into yeast (酵母). This genetic modification (改造) 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 (常规的) milk production, their process uses 65% less energy, creates 84% less greenhouse gas emissions (排放) 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 (素食的) consumers will no longer have to deal with the unpleasant 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 many good cows’ milk products available to consumers.
【1】The underlined word “those” in paragraph 1 refers to _______.
A.actions B.products C.people 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
【3】What can be inferred from paragraph 4?
A.The dairy-free products cannot be stored for a long time.
B.Cow farming causes considerable environmental damage.
C.The new products will taste better than dairy-based ones.
D.The dairy-free milk will be more expensive than cow’s milk.
【4】Which of the following can be the best title for the text?
A.Healthier Cheese
B.New Milk Saves Planet
C.Making Milk without Cows
D.Fresher Milk, Better Future
27、Running and walking are both excellent forms of exercise. Those who regularly do either usually have healthier hearts, stronger bones and lower body weights than those who do little exercise. But does it matter whether you spend time walking or running? Arguments can be made for both, and which is right for you depends on your goals and your present fitness level.
“The key difference between running and walking is how many calories you are burning—not per mile, but per minute of exercise says Paul D. Thompson, a doctor at Hartford Hospital.” “Running is a more-efficient (高效的) movement and it’s more demanding on the body, so it bums more calories per minute,” Thompson says. “But if you’ve got the time to walk long enough to bum the same amount of calories, then walking is fine.” That said, if your final goal is to lose weight, chances are that neither running nor walking alone is going to do the trick. Research has shown that it needs to be done along with calorie control.
In a recent study that analyzed data from nearly 50,000 people, researchers found that runners’ risk of heart disease was 4.5 percent lower than that of those who were inactive. But walkers who burned the same amount of calories daily had a risk level that was 9 percent lower than those who were inactive.
“Running gets the reputation (名声) for causing injuries because many people who are just starting to run try to do too much too quickly,” says Carol Ewing Garber, a professor at Columbia University. “And they often get injured as a result. If you want to progress from walking to running, do it slowly, gradually increasing your speed, distance and the frequency of your rums.
Running may be more highly-intense (高强度的) and calorie-burning than walking, but walking is a great way to ease into exercise and make sure you are staying physically active every day. The bottom line is that getting exercise of any kind is beneficial—if you keep doing it.
“The best exercise is the one you are going to do,” Thompson says. “There are extra benefits to be gained from running, but what’s most important from a public health point of view is that everyone gets out and does some kind of exercise?”
【1】What can we infer from Paragraph 2?
A．Exercise on its own is not enough to lose weight.
B．Walking is better than running for busy people.
C．Running can reduce people’s fat quickly and safely.
D．Walking is more demanding on the body.
【2】What can we learn from the recent study?
A．Running bums fewer calories than walking.
B．Walkers are more likely to get heart disease than runners.
C．Walking can reduce the risk of having heart disease.
D．Inactive people are free from heart problems.
【3】Which of the following would Thompson most probably agree with?
A．We’d better walk slowly.
B．Just walk before you run.
C．We’d better choose to run.
D．Any exercise is better than none.
28、In the last two weeks, the only things that have been thrown by Esther Penarrubia have been a broken toy, an old T-shirt used to clean shoes, a balloon from a party and the backing from a sheet of stickers. Ms Penarrubia, who has a PhD in agricultural engineering, realized that her lifestyle was called “zero waste” after watching a TED talk in November 2015.
It was when Ms Penarrubia moved house that she decided to remove single-use plastic from her life to reduce her family’s waste and thus changed her lifestyle.
Bulk (批量) buying, reusing old materials, searching second-hand shops and minimizing products which use plastic have been the key factor to her lifestyle, which sees her family send just one piece of rubbish to landfill every fortnight. Ms Penarrubia tries to remove all plastic products but if she does purchase any, like olive oil, she will bulk buy in a five-litre bottle and will recycle when finished. This also applies to cleaning products. Glass jars and containers are repurposed after use and kitchen leftovers go in the compost (堆肥) bin. The family grow their own tomatoes, cabbages, broccoli and herbs at home and also have orange and apple trees, while she buys fresh fruit, vegetables and bread in bulk from local suppliers for the week.
Ms Penarrubia believes changing to a zero-waste lifestyle is easier and cheaper than per-ceived, but admits the challenging part in convincing others that it can be achievable. She said, “If you think and organize your buying habits, consume less things from better quality, choose reusable alternatives, buy everything you can in quantity from the second-hand market—then it’s not more expensive and you can save money. “Zero waste” culture doesn’t only consist of the reduction of our waste, it involves a more conscious lifestyle and way of consumption.
【1】What has Esther thrown during the past two weeks？
A．A balloon and an old T-shirt.
B．A broken toy and a pair of shoes.
C．An old T-shirt and some stickers.
D．A balloon and some glass containers.
【2】When did Esther begin to live a zero waste life？
A．Two weeks ago.
B．After watching a TED talk.
C．When moving into the new home.
D．After running a second-hand shop.
【3】How did Esther live a lifestyle of zero waste？
A．By eating less.
B．By running a second-hand shop.
C．By recycling and shopping smartly.
D．By making all the daily goods by herself.
【4】What does Esther think of practicing the zero waste？
A．It’s too expensive.
B．It’s within easy reach.
C．It’s unlikely to work.
D．It’s much more demanding.
29、Debris flow (泥石流) is a kind of destructive geological disaster. July to August is the most frequent period of debris flow in China. 【1】, it can increase the probability of survival in an emergency.
Don’t overlook your surroundings while hiking. Pay attention to the surrounding environment and pay special attention to whether you hear thunder-like sound from the valley in the distance. If you hear it, you should raise the alarm. 【2】.
Don’t panic and escape in the direction of debris flow. When meeting with debris flow, stay calm. 【3】.

31、Directions: Complete the following passages by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
The elementary means of communicating with other people is conveying messages by voice. This fact is widely acknowledged and we recognize the voice as a(n) 【1】 characterizing the identity of a person. The array of voices is immeasurable as no two are exactly similar. They can be nasal, resonant or shrill produced in accordance with the individual physical【2】 of the throat.
One possible implementation of the 【3】 of voice recognition is voice profiling used by police analysts as a method of substantiating court evidence in trials. Every year, thousands of audiotapes with recorded interviews or 【4】 utterances are put to the purpose to help identify the probable 【5】. Specialists dealing with the voice investigation claim that people can give themselves away by their 【6】, inflections or other voice attributes like pitch, intensity and loudness. A recorded sample is usually 【7】 into electric impulses and later transformed into a pictorial recoding which is processed by a computer program. Very frequently voice analyst have a stake at deciphering the relevant information which may be 【8】 with background noise or other interfering sounds until they attain the 【9】 results.
Thankfully, these efforts help the police detect individuals who threaten their victims by phone or inform about bomb 【10】 or those who make offensive calls disturbing the peach of decent citizens.
