【推荐2】Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet’s health, and people’s health may be suffering from it.
The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes more clean, sometimes not.”

It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content (含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn’t have fluoride (氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that’s behind the recent rise in bad teeth.
Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals (化学物质) into the water.
According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.
In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.
So, if you are worried about the effect of bottled water on the Earth, you can take the following steps.
● Drink from your tap. Unless your government warns against this, it should be fine.
● Get a container (容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.
● Keep it cool. Don’t drink from a bottle that has been sitting in the sun, don’t store it near chemicals, and don’t reuse plastic bottles.
● Choose glass containers over plastic if possible. When finished, recycle!

【推荐3】A day in the clouds

The air is thin and we have to rest several times on the short hike(徒步旅行)from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the plain(平原) in front of us, we can just make out a herd of graceful animals. This is why we stay here.

Tibetan antelopes live mainly on the plains of Tibet. Watching them move slowly across the green grass, I'm struck by their beauty. I'm also reminded of the danger they are in. They are being hunted, illegally, for their valuable fur.

My guide is Zhaxi, a villager from Changtang. He works at the Changtang Nationa Nature Reserve(保护区) . The reserve is a safe place for the animals and plants of northwestern Tibet. To Zhaxi, protecting(保护)the wildlife is a way of life. "We're not trying to save the animals." he says. "Actually, we're trying to save ourselves."

In the 1980s and 1990s the population of Tibetan antelopes dropped by more than 50 Percent. Hunters were shooting antelopes to make money. Their Living places were becoming smaller as new roads and railways were built.

In order to save Tibetan antelopes, the Chinese government placed them under national protection. Zhaxi and Volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.

The measures were effective. The antelope population has recovered and in June 2015, the Tibetan antelope was removed from the endangered species list(濒危物种名单). The government, however, does not intend to stop the protection programmes, since the threats(威胁) to the Tibetan antelope have not yet disappeared. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.

【推荐2】It would be nice if eating a particular food could magically protect you against all the boring illnesses. It’s not that simple, of course. Hand washing remains your best defense against picking up illnesses, and sleep is a strong defense too. But what you eat does play an important part. Though it isn’t because of just one or two foods, what you eat in your daily diet has an effect on how weak or strong your immunity (免疫力) is.

We’d better eat fruit and vegetables every day. They contain key vitamins needed in the immune system. For example, vitamin A and vitamin C in foods help the immune system work well to keep us healthy. Remember that eating actual fruit and vegetables is better than eating single-vitamin supplements.

Getting too little protein can weaken your immune system. Protein-rich foods supply the amino acids (氨基酸) you need to build important protein in your body. Beef and pork also contain zinc, which your body uses to make T-cells that help your body fight disease.

Fermented (发酵的) foods are foods that are naturally protected by bacteria. Fermented foods like yoghurt help beneficial bacteria develop fast in the stomach, leaving less room for harmful bacteria.

1. What does paragraph 1 mainly tell us?

A．Hand washing is necessary.

B．Illnesses make people bored.

C．Immunity has much to do with your diet.

D．More sleep does good to health.

2. Why does the author suggest we eat fruit and vegetables every day?

A．They are rich in vitamins we need.

B．Vitamin A is beneficial to immunity.

C．Fruit supplies our body with vitamin C only.

D．Eating single-vitamin foods does little good.

3. What can we infer from paragraph 3?

A．Amino acids can help to make T-cells.

B．A healthy body needs plenty of protein.

C．The immune system can be hurt easily.

D．We should eat beef as much as possible.

【推荐3】There have been numerous wake-up calls about the effects of climate change on sea life. As ocean waters heat up, they are making coral lose color. Growing levels of carbon dioxide are making seawater more acidic. Now climate change is starting to affect fish's sense of smell, a phenomenon that will worsen in the coming years if global warming continues growing.

A sense of smell is what the fish can't do without. They use it to find food, detect upcoming danger, escape from predators (捕食者）find safe environments, and even recognize one another. "Future levels of carbon dioxide can have large negative effects on the sense of smell of fish, which can affect fish population numbers and the entire ecosystem, ”said an ocean life expert. "This can be prevented, but we must reduce carbon emissions now before it's too late.”

Experts believe that about half of carbon dioxide emissions produced by human activities, such as the burning of fossil fuels--have over time ended up in the oceans, lowering the pH of seawater, and making it more acidic.

Researchers found that sea bass (鲈鱼）exposed to the more acidic conditions swam less and were less likely to react when encountering the smell of a predator. Also, they were more likely to "freeze", a sign of anxiety, according to the study. They found the longer the fish were in high CO2,the worse they got along. The researchers also measured the ability of the fish to detect certain odors (气味）in different levels of acidity (酸度）。 The study showed that their ability to detect and respond to some odors connected with food and threatening situations was more strongly affected than other odors.

The research is important because 20 percent of the protein consumed by 3 million people comes from seafood, and about 50 percent of this comes from fish caught from the wild. “Therefore, increases in carbon dioxide in the ocean have the potential to affect all fish species, including those that many people rely on food and livelihood, "the ocean life expert warned.

1. What do we know from the first paragraph?

A．Global warming will continue in the coming years.

B．Global warming is starting to affect fish's sense of smell.

C．The temperature of seawater is rising to a dangerous level.

D．Few people are worried about the impact of climate change.

【推荐2】Granny had just bought a sandwich for her office and was stopped at a red light in the city center. She had the window rolled down to enjoy the soft wind when a man rushed up to the driver’s side window to rob her. The robber broke into the open window with one hand in his pocket. He ordered Granny to get out of the car, or he would shoot her. A word like that would have frightened anyone else. Instead, Granny saw it as a challenge.

Completely unafraid she said that if he really had a gun, he would have pulled it out. She was right. The criminal had no gun actually and tried to pull her out of the car. Granny sounded the horn and started shouting out to draw others’ attention. With the door now open, she started kicking the man anywhere her foot could reach. After a kick to his stomach, the man attempted to escape. But Granny wouldn’t stand for that. It was now her turn to grab onto him. That poor fool didn’t have a chance. She called for help to bystanders, and they rushed to her aid. With Granny leading the charge, a group of strangers came together and took the man to the sidewalk, holding him there until the police came.

When asked by a young reporter covering the story why she fought back and wasn’t afraid, Granny’s answer was surprisingly simple: She had had her new car for less than two days and a pack of good sandwiches for her office.

【推荐3】People with genetic syndromes(综合症) sometimes have telltale (泄露秘密的) facial features, but using them to make a quick and cheap diagnosis can be tricky given there are hundreds of possible conditions they may have. A new neural network that analyzes photographs of faces can help doctors narrow down the possibilities.

Yaron Gurovich at biotechnology firm FDNA in Boston and his team built a neural network to look at the gestalt --- or overall impression --- of faces and return a list of the 10 genetic syndromes a person is most likely to have.

They trained the neural network, called DeepGestalt, on 17,000 images correctly labelled to match more than 200 genetic syndromes. The team then asked the AI to identify potential genetic disorders from a further 502 photos of people with such conditions. It included the correct answer 91 per cent of the time.

Gurovich and his team also tested the neural network’s ability to distinguish between the different genetic mutations (变异) that can lead to the same syndrome. They used photographs of people with Noonan syndrome, which can result from mutations in any one of five genes. DeepGestalt correctly identified the genetic source of the physical appearance 64 per cent of the time. It’s clearly not perfect, but it’s still much better than humans are at trying to do this.

As the system makes its assessments, the facial regions that were most helpful in the determination are highlighted and made available for doctors to view. This helps them to understand the relationships between genetic make-up and physical appearance.

The fact that the diagnosis is based on a simple photograph raises questions about privacy. If faces can reveal details about genetics, then employers and insurance providers could, in principle, secretly use such techniques to discriminate against people who have a high probability of having certain disorders. However, Gurovich says the tool will only be available for use by clinicians(临床医生). Clinically, this technology can help narrow down the search space of diagnosis and then confirm through checking genetic markers. Besides, it could perhaps add means of finding other people with the disease and, in turn, help find new treatments or cures.

【推荐1】A team of engineers at Harvard University has been inspired by Nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.

“It’s extremely important for us to think about this as a whole system and not just the sum of a bunch of individual components,” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing together the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.

They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything it’s connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.

While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites, in farmers’ fields or on the battlefield. “Basically, it should be able to take off, land and fly around,” he said.

Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”

1. Which of the following statements was the difficulty engineers met while making the robotic fly?

A．They did not have sufficient fund.

B．No ready-made components were available.

C．There was no model in their mind.

D．It was hard for them to assemble the components.

2. What can be inferred from paragraphs 3 and 4?

A．The robotic fly has been put into wide application.

B．The robotic fly consists of a flight device and a control system.

C．Information from many sources can be collected by the robotic fly.

D．The robotic fly can just fly in limited areas at present.

3. Which of the following can be learned from the passage?

A．Wood’s design can replace animals in some experiments.

B．Animals are not allowed in biological experiments.

C．The robotic flyer is designed to learn about insects.

D．There used to be few ways to study how insects fly.

4. Which of the following might be the best title of the passage?

A．The Development of Robotic Fly

B．Robotic Fly Promotes Engineering Science

C．Harvard’s Efforts in Making Robotic Fly

D．Robotic Fly Imitates Real Life Insect

【推荐2】One morning, Ann’s neighbor Tracy found a lost dog wandering around the local elementary school. She asked Ann if she could keep an eye on the dog. Ann said that she could watch it only for the day.

Tracy took photos of the dog and printed off 400 FOUND fliers (传单), and put them in mailboxes. Meanwhile, Ann went to the dollar store and bought some pet supplies, warning her two sons not to fall in love with the dog. At the time, Ann’s son Thomas was 10 years old, and Jack, who was recovering from a heart operation, was 21 years old.

Four days later Ann was still looking after the dog, whom they had started to call Riley. When she arrived home from work, the dog threw itself against the screen door and barked madly at her. As soon as she opened the door, Riley dashed into the boys’ room where Ann found Jack suffering from a heart attack. Riley ran over to Jack, but as soon as Ann bent over to help him the dog went silent.

“If it hadn’t come to get me, the doctor said Jack would have died,” Ann reported to a local newspaper. At this point, no one had called to claim the dog, so Ann decided to keep it.

The next morning Tracy got a call. A man named Peter recognized his lost dog and called the number on the flier. Tracy started crying, and told him, “That dog saved my friend’s son.” Peter drove to Ann’s house to pick up his dog, and saw Thomas and Jack crying in the window.

【推荐3】Many of us are quick to blame（责备）others for how we feel: "He makes me so mad!" or "he really hurt my feelings. "But did someone really "make me angry" or are we feeling the anger in us getting kicked up in response to the way someone behaved towards us?

The difference between the two is in who the responsible party is for the way we feel. If we blame others for our feelings we will finally feel reasonable at whatever our retaliation（报复）my be, and we will explain that it was their fault, not ours. "They were driving me mad".

When we blame others for the way we feel we have in fact given power to others for the state of our emotional wellbeing（健康）. The truth is , no one controls our feelings but us. If we are finding that people in our lives really know how to "push our buttons（means make us angry）" then we are not doing a good enough job at protecting our "buttons." We are the ones leaving our buttons out in the open so that other people can "push them." Ultimately, the switch for our buttons is inside us - not on the outside.

While there are some things in life that are clearly out of our control , like the weather or a flight that's two hours late, how we act and respond to other people's behavior is not among them. Our responses to others are well within our control.

If someone is "making us" so mad , for example, that we get angry, we are not doing enough to learn about what drives our anger and how to properly cope with it. My suggestion is taking time before you get angry. and putting some work into taking an inventory（清单）of the past. An inventory can show you how much of your past experiences influence your feeling reactions in the current moment.

When we finally realize that so much of our present feelings and reactions are driven from within ourselves and our own past experiences, we will be ready to make the changes in our lives that will better secure our buttons so that they are no longer left out in pubic for everyone to push at will.

1. What result will appear if we blame others for our emotions（情感）?

A．We consider others to be correct.

B．We consider ourselves to be correct.

C．We consider we were driving ourselves mad.

D．We consider they were driving themselves mad.

2. What's the author' attitude towards feelings?

A．We should blame others for the way we feel.

B．We should enable others to control our feelings.

C．We should let others know our daily life clearly

D．We should control personal feelings ourselves.

3. According to the author, which can always be under our control?

A．Our own behavior.	B．The delay of a flight
C．Other people' s feelings.	D．The weather conditions.

4. Which proverb best suits the author' s advice in Paragraph 5?

A．A burden of one's choice is not felt.	B．Think twice before acting.
C．A friend is easier lost than found.	D．A good beginning is half done.
