第二部分阅读理解（满分40分）阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。

21．（6分）Life hasn’t always been easy for Sareana Kimia, 16. Her parents split up when she was young, and she hasn’t seen her dad since she was l0. In June 2014, she and her mom, Shefali Gupta, found out that they would soon be evicted (逐出) from their home. Sareana knew that her mom had money problems.

Even before the eviction, Gupta had become very sad. Because she didn’t have health insurance,

Gupta couldn’t get a doctor’s help for her emotional problems.

Sareana took charge of things at home. For exam ple, she often cooked her family’s meals. When she and her mom were about to lose their home, it was Sareana who arranged a place for them to stay.

For years, Sareana had been an active volunteer with several organizations. She even started her own group, Youth for National Change. It works to support the rights of young people.

Sareana called a few adults she had worked with. After finding out about her situation, one couple opened their doors right away. But by August 2014, the couple no longer had room for Sareana and her mom. The two ended up living in their car. They didn’t want to go to a homeless shelter out of fear that they could be split up. Through it all, Sareana kept working on projects and studying. “At no point did I let what was going on chan ge my daily routine,” she says.

Sareana is homeschooled online and goes to classes at a nearby college. Last fall, school bills began piling up. She had no way to pay them. A friend suggested that she try raising funds online. After a newspaper ran an article about Sareana, donations poured in-nearly $ 30,000! She paid for school and had enough money left to rent a small apartment. She and her mom moved into it in January 2015.

1、What happened to Sareana in 2014?

A．She lost her father. B．She became homeless.

C．Her mom abandoned her. D．Her house was destroyed.

2、Sareana started an organization to .

A．teach people to cook B．support poor people

C．earn money D．help youth

3、Sareana finally found her own apartment .

A．by raising money B．by doing part—time jobs

C．with the help of her friends D．with the help of her colleg

22．（8分）Imagine you’re standing in line to buy a snack at a store. You step up to the cou nter and the cashier scans your food. Next, you have to pay. But instead of scanning a QR Code(二维码) with your smart phone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.

Now, this type of technology might not be far away. As technology companies move away from the traditional password, biometric (生物特征识别的) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

In 2013, Apple introduced the iPhone 1s, one of the first smart phones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become a commonplace, bringing convenience to our lives. And since 2012, Samsung has featured eye-scanning technology in its top

smart phones, while Apple's new iphone X can even scan a user's face. But despite its popularity, experts warn that biometrics might not be as secure as we imagine. " Biometrics is ideally good in practice, not so much," said John Michener, a biometrics expert.

When introducing the new iPhone's face ID feature, Phil Schiller, Apple's senior vice-president, said. "The chance that a random person in the population could look at your iPhones X and unlock it with their face is about one in a million." But it's already been done. In a video posted on a community website Reddit, two brothers showed how they were each able to unlock the same iPhone X using their own face. And they aren't even twins.

"We may expect too much from biometrics," Anil Jain, a computer science professor at Michigan State University, told CBS News. "No security systems are perfect."

Earlier last year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smart phone for the police, according to a tech website Splinter. "It's good to see biometrics being used more," Jain told CBS News, "because it adds another factor for security. But using multiple security measures is the best defense."

1、Which is the latest identification technology in a smart phone according to the passage?

A．Face scanning. B．Eye scanning.

C．QR Code scanning. D．Fingerprint scanning.

2、What is a major problem of the iPhone X's face ID system?

A．It takes too long to unlock the phone.

B．It often fails to recognize its owner's face.

C．Face data can be used for other purposes.

D．Different faces can be used to unlock the same phone.

3、What is Anil Jain's opinion about biometric security?

A．It is as secure as traditional measures.

B．It is perfect without much improvement.

C．It has caused much trouble for the police.

D．It should be used with other security measures.

4、What does the author intend to tell us in this passage?

A．The popularity of biometrics.

B．Security problems of biometrics.

C．Various problems with biometrics.

D．Great changes caused by biometrics.

23．（8分）Do’s and Don’ts in Whale (鲸) Watching

The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel (船只) operators follow these guidelines for all kinds of whales.

? Approach whales from the side, not from the front or the back.

? Approach no closer than 100 metres, then st op the boat but keep the engine on.

? Keep noise levels down — no horns, whistles or racing of engines.

? Start your boat only after the whales are more than 100 metres from your vessel

? Leave the area slowly, gradually moving faster when you are more tha n 300 metres from the whales.

? Approach and leave slowly, avoiding sudden changes in speed or direction.

? Avoid disturbing groups of resting whales.

? Keep at low speeds and remain in the same direction if traveling side by side with whales.

? When whale s are traveling close to shore, avoid crowding them near the shore or coming between the whales and the shore.

? Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.

? If there is more tha n one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.

? Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.

1、For whom is this text written?

A．Tour guides. B．Government officials.

C．Whale watchers. D．Vessel operators.

2、When leaving the observation areas, the vessel should .

A．move close to the beach B．increase speed gradually

C．keep its engine running slowly D．remain at the back of the whales

24．（8分）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 friendly. According to the company’s website, when compared to conventional m ilk 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 nume rous good cows’ milk alternatives available to consumers.

1、The underlined word “those” in paragraph 1 refers to ________.

A．alternatives 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．the poor taste of dairy-free cheese presently available

C．the over-consumption of the dairy-based products

D．their worry that farm animals were poorly treated

3、What can be inferred from paragraph 4?

A．Cow farming causes considerable environmental damage.

B．The new products will taste better than dairy-based ones.

C．The dairy-free products cannot be stored for a long time.

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

25．（10分）I was born on the 17th of November 1828, in the village of Nam Ping, which is about four miles southwest of the Portuguese Colony (殖民地) of Macao, and is located on Pedro Island lying west of Macao, from which it is separated by a channel of half a mile wide.

As early as 1834, an English lady, Mrs. Gutzlaff, wife of a missionary to China, came to Macao. Supported by the Ladies’ Association in London for the promotion of female education in India and the East, she immediately took up the work of starting a girls’ school for Chinese girls, which was soon followed by the opening of a boys’ school.

Mrs. Gutzlaff’s comprador(买办) happened to come from my village and was actually my fa ther’s friend and neighbor. It was through him that my parents heard about Mrs. Gutzlaff’s school and it was doubtlessly through his influence and means that my father got me admitted into the school. It has always been a mystery to me why my parents should put me into a foreign school, instead of a traditional Confucian school, where my big brother was placed. Most certainly such a step would have been more suitable for Chinese public opinion, taste, and the wants of the country, than to allow me to attend an English school. Moreover, a Chinese belief is the only avenue in China that leads to political promotion, influence, power and wealth. I can only guess that as foreign communication with China was just beginning to grow, my parents hoped that it might be worthwhile to put one of their sons to learning English. In this way he might become an interpreter and have a more advantageous position to enter the business and diplomatic world. I am wondering if that influenced my parents to put me into Mrs. Gutzla ff’s School. As to what other sequences it has eventually brought about in my later life, they were entirely left in the hands of God.

1、How was the author admitted to Mrs. Gutzlaff’s school?

A．Through his father’s friend’s help.

B．Through his own efforts to exams.

C．Through his father’s request.

D．Through Mrs. Gutzlaff’s influence.

2、Why did the author’s parents put him into an English s chool？

A．An English school was more influential.

B．Foreign trade with China was developing fast.

C．It met with Chinese public opinion.

D．He could become a successful interpreter.

3、What did the author think of his parents’ decision to put him into an Engli sh school?

A．It was skeptical. B．It was mysterious.

C．It was thoughtful. D．It was wonderful.
