4 . Onions may be one of the healthiest, most flavorful vegetables on the face of the Earth, but they’re definitely no fun to chop. However, your days of getting teary-eyed in the kitchen may be coming to an end as Japanese company House Foods Group prepares to launch the world’s first tear-free onion to the market.
Properly the onion is named “Smile Ball”, because it puts a smile on your face rather than make you cry, this new type of onion is the result of two decades of research. In 2002, House Foods Group scientists published a paper in which they assumed that tear-inducing enzymes(酶) in onions could be weakened while keeping their full flavor and nutritional value. Last year the company announced that their theory had finally become reality. Although the announcement mentioned that House Foods Group had no intention of producing Smile Ball onions commercially anytime soon, it appears the wonder vegetables will hit Japanese stores this fall.
It has long been known that cutting onions causes tears due to a volatile gas(挥发性气体) given out by onion cells when damaged by the knife. But cutting the Smile Ball onion in any condition is reportedly a tear-free experience.
About five tons of Smile Ball onions were sold in trial runs at Tokyo department stores and online shops this year, but this fall, they will be available at supermarkets nationwide, at a price of 450 yen ($4.30) for a pack of two. That’s twice as expensive as regular onions.
The rate at which the trial batch of 5-6 tons of Smile Ball onions sold out signals that they will be a huge hit when they hit the market.
1. Why do people tear when cutting onions?| A．A volatile gas is given out. | B．People are allergic to onions. |
| C．Onions can hurt people’s eyes. | D．Too many onions are wasted. |
| A．450 yen | B．250 yen | C．＄2.15 | D．＄4.30 |
| A．Strike | B．Success | C．Failure | D．Knock |
| A．A funny research |
| B．The healthiest vegetables |
| C．Crying onion |
| D．Smile Ball |
5 . Twitter is an online social networking service that enables users to send and read short 140-character messages called “tweets”. I rarely meet a Twitter user who doesn’t want more followers. Therefore, I’d like to share with you how I have built my own follower count to more than 240,000 followers since I began with Twitter.

• Be generous in linking to and retweeting others.
• Avoid too much promotion. Yes, you can advertise your blog posts, products, etc. on Twitter, but be careful.
• Don’t use an auto-responder. I used to use Social Oomph to thank everyone who followed me and provide a link to my “Beginner’s Guide to Twitter”. I thought I was being polite and helpful.
Finally, don’t worry too much about the numbers. If you follow the advice I have given above, the numbers will take care of themselves.
| A．There’s a line you must not cross |
| B．Some of these will follow you back |

It was the worst day ever and I'll never forget it. The day began as usual. My husband, Alan, entered his office in our home and participated in conference calls. In the kitchen, I could hear him speaking on the phone to his boss. Suddenly, I heard some words that were absolutely alarming.
When he exited his office moments later, my fears were confirmed- Alan had been laid off. I hugged him as my heart sank, and my mind raced: What were we going to do with his unemployment? Would we lose our house if we couldn't afford to pay for it?
“We'll be fine,” he said.
“I know," I responded.
But, frankly, neither of us was very convincing. I wanted to be in bed with covers over my head, but I had to make my way to work. It was an hour into my shift before I received a call from the doctor. I had noticed some strange lumps in my neck, and he'd been performing tests to determine the cause
“You have cancer,” he stated. I distinctly remember my response: “What?” I must have misheard. It sounded like he said I had cancer, but that was completely ridiculous. I had always been healthy and cancer was out of the question. The doctor repeated those terrible words. It was true: Cancer was in my body. He went on discussing future treatment plans and appointments, I think. I really wasn't listening anymore.
As I drove home, I thought about how wonderful things had been up until this day. Now it's time to pay back for all those amazing years. I prepared myself for a hopeless future, or no future at all.
Alan hugged me when I arrived home, and I cried as he held me tight. “Someday in the future, we're going to write about today,” he whispered in my ear, “and we'll call it Worst Day Ever. ”

7 . Some love speaking in public, while others are scared at the thought of it. Stage fright is perfectly normal.
Nothing will stop stage fright more effectively than being prepared. Know your content, your speech and more importantly your audience. If you know what you are talking about then you have no reason to be nervous. Also, should a technical problem occur, you can stay cool as you are already confident on the subject.
Practice,Practice, Practice
Talk Yourself Down
Even though stage fright is “all in the mind,”the fear appears itself in physical ways. The best solution is to change your negative talk. Stop worrying about “What if I forget the content?”
It Is Not All About You
Though you might feel like everyone is out to laugh, criticize or judge you, that is not the case. Get over the feeling that the world is going to hang on your every mistake. Just focus on your speech, audience and what they deserve from you.
| A．Know Your Stuff |
| B．Stay calm and cool |
| C．Change that into positive talk |
| D．Sooner or later, something will go wrong |
| E．This will ease the pressure that is already building up |
| F．To fully overcome it, it is important to understand what stage fright is |
| G．Knowing your stuff helps, but it doesn't necessarily wipe out the problem |
8 . Researchers based in the greater Yellowstone National Park area have found a new way to identify mountain lions-also referred as pumas- by using facial recognition. And it is proving to be effective to monitor these creatures that are highly elusive. “Mountain lions are really hard to directly observe.” said Peter Alexander, a research biologist leading the research project.
One tool they once used is a camera trap, which is attached to something along the animal’s regular path. When motion is detected, the trap gets a shot of the mountain lion as it passes by. The cameras even have an infra-red (红外线的)flash for nighttime photos without disturbing the animal.
Researchers around the world use this type of tool to estimate population numbers of species. But according to Alexander, there’s a problem with this method when it comes to ID’ing mountain lions.
All mountain lion around the world have light, sandy colored fur down their sides. The scientific name for a mountain lion, Puma concolor, literally translates to “one color”. This lack of unique coloration (自然花纹)on the their body sides means researchers like Alexander can’t usually tell if one puma crosses a camera trap five times, or if five individual animals pass by.
However, it’s a different story with their distinctive facial markings. Alexander and his team added some devices to their camera traps so that when motion was detected, a puma kitten call was played. This noise reliably attracted passerby pumas so that they looked up long enough for the camera trap to grab a shot for facial recognition.
Compared to the traditional side angle camera trap, the new attention-getting device was about 92% more accurate. This work was recently published in the journal Ecology and Evolution.
This study is an important step to being able to more confidently identify and track animals. Getting head images of mountain lions also opens up new opportunities to involve AI techniques. Alexander says that this new camera trap method could be used for tracking other wild animals that lack distinguishing side colors but have unique features elsewhere.

| C．It helps greatly advance AI techniques. | D．It is more convenient than traditional ones. |
9 . Australia is unique in many ways. It’s home to a wide range of landscapes and some of the most unusual animals on Earth. The Land Down Under is also the only place on Earth that qualifies as both a country and a continent. The definition of a continent isn’t as concrete as you might expect, but a few qualities help earn Australia that distinction.
The land mass’s status (地位) as a country is for sure. A country is defined as “a nation with its own government, occupying a particular territory,” and since 1901, the Commonwealth of Australia—as it’s officially known—has fit that description.
Australia’s claim to be a continent is less strong. There’s no scientific definition used to categorize continents. They tend to be large land masses with their own tectonic plates (地壳板块), and isolated enough to produce unique cultures and plant and animal populations. These aren’t hard and fast rules, however. Europe and Asia share a tectonic plate, but their cultural differences justify separating them into two continents (though the boundary separating one from the other is constantly changing). When it comes to what makes Australia a continent, size is the most minor factor. It’s the smallest continent at 2. 9 million square miles, and it’s actually closer in size to Greenland than it is to South America. So what makes Australia a continent and Greenland an island?
Australia’s distinctiveness carries a lot of weight here. Its isolated location allowed it to support native groups of people with distinct cultures as well as wildlife that can’t be found elsewhere on the planet. The native cultures and animals of Greenland, however, can also be found throughout the Arctic.
1. What qualifies Australia as a country?| A．The distinct landscapes and animals it has. |
| B．The establishment of Commonwealth of Australia. |
| C．The reputation of the Land Down Under it enjoys. |
| D．The specifically defined continent where it is located. |
| A．The dividing line between Asia and Europe stays fixed. |
| B．Size is a major factor in determining Australia as a continent. |
| C．Each continent occupies a tectonic plate separated from others. |
| D．The definition of a continent doesn’t necessarily follow set rules. |
| A．Because it is much smaller than South America. |
| B．Because it does not cover a whole tectonic plate. |
| C．Because it lacks uniqueness in culture and wildlife. |
| D．Because it is too close and is attached to the Arctic. |
| A．How Is Australia Different from Greenland? |
| B．How Were the Continents on Earth Determined? |
| C．What Sets Australia Apart from Other Continents? |
| D．Why Is Australia a Continent as Well as a Country? |
10 . A family’s cat has finally been recovered after three weeks of being on the run in Boston’s Logan International Airport. The cat -named Rowdy-had been successfully avoiding airport workers, airline employees, and animal experts since escaping from a pet container. Rowdy was finally caught Wednesday.
“Whether out of exhaustion or hunger we’ll never know, but this morning she finally let herself be caught,”an airport spokesperson said.
Rowdy is to be given a health examination and then returned to her family. “I’m kind of in disbelief,”said her owner, Patty Sahli. “I thought, ‘What are the odds we’re actually going to get her back?’ But I got a call this morning and I am just so shocked. ”
Rowdy’s time on the run began June 24. Sahli and her husband, Rich, returned to the United States from 15 years in Germany with the Army. When their Lufthansa airlines flight landed, the 4-year-old black cat with green eyes escaped her cage. She was chasing some birds in the area.
Soon Rowdy herself was on the object of a chase. Her escape set off a big search involving airport and Lufthansa workers. Construction workers, and animal welfare experts got involved as well. They used wildlife cameras and safe-release traps in an attempt to catch Rowdy. Many people saw Rowdy during her extended airport visit. However, the cat always escaped those who chased her.
Now, with Rowdy safely contained, a little calm has been returned to the airport. “It was such a community effort,” said Sahli, adding, “we’re just so grateful to everyone who helped look for her. ”
1. What finally led to Rowdy’s being caught?| A．The use of wildlife cameras. | B．The attraction of some birds to her. |
| C．Animal welfare experts’ involvement. | D．Her willingness to cooperate in the chase. |
| A．Getting away from the family. | B．Returning home safe and sound. |
| C．Caught by the safe-release traps. | D．Injured and shocked at the airport. |
| A．The efforts of the cat’s owner. | B．The process of chasing the cat. |
| C．The cause of the cat’s losing her way. | D．The whole story of the cat’s getting loose. |
| A．Individual and effective. | B．Extensive and combined. |
| C．Determined but failed. | D．Demanding but overlooked. |
