1 . Dogs greet other dogs nose-first, as it were—sniffing each other from fore to (especially) aft. People are not quite so open about the process of sniffing each other out. But the size of the perfume industry suggests scent is important in human relations, too. There is also evidence that human beings can infer kinship (亲戚关系), deduce emotional states and even detect disease via the sense of smell.

Now, researchers of the Weizmann Institute of Science in Israel, have gone a step further. They think they have shown, admittedly in a fairly small sample of individuals, that friends actually smell alike. They have also shown that this is probably the case from the beginning, with people picking friends at least partly on the basis of body odour (气味), rather than the body odours of people who become friends subsequently converging (趋同).

They stated their research by testing the odours of 20 pairs of established non-romantic, same-sex friends. They did this using an electronic nose and also two groups of specially employed human “smellers.” The e-nose employed a set of gas sensors to assess T-shirts worn by participants. One group of human smellers were given pairs of these shirts and asked to rate how similar they smelt. Those in the other group were asked to rate the odours of individual T-shirts on five subjective dimensions: pleasantness, intensity, attractiveness, competence and warmth. All three approaches yielded the same result. The T-shirts of friends smelt more similar to each other than the T-shirts of strangers. Friends, in other words, do indeed smell alike.

Why scent might play a role in forming friendships remains obscure. Other qualities related with being friends, including age, appearance, education, religion and race, are either immediately obvious or rapidly become so. But while some individuals have strong and noticeable body odour, many—at least since the use of soap has become widespread—do not. It is present. But it is subconscious.

Xiao long bao (soup dumplings), those amazing constructions of delicate dumpling wrappers, encasing hot,     1     (taste) soup and sweet, fresh meat, are far and away my favorite Chinese street food. The dumplings arrive steaming and dangerously hot. To eat one, you have to decide whether     2     (bite) a small hole in it first, releasing the stream and risking a spill (溢出),     3     to put the whole dumpling in your mouth, letting the hot soup explode on your tongue. Shanghai may be the     4     (recognize) home of the soup dumplings but food historians will actually point you to the neighboring canal town of Nanxiang as Xiao long Bao’s birthplace. There you will find them prepared differently — more dumpling and less soup, and the wrappers are pressed     5     hand rather than rolled. Nanxiang aside, the best Xiao long bao have a fine skin, allowing them     6     (lift) out of the steamer basket without tearing or spilling any of     7     (they) contents. The meat should be fresh with     8     touch of sweetness and the soup hot, clear and delicious.

No matter where I buy them, one steamer is     9     (rare) enough, yet two seems greedy, so I am always left     10     (want) more next time.

3 . On Oct. 11, hundreds of runners competed in a cross-country race in Minnesota. Melanie Bailey should have _________ the course earlier than she did. Her _________ came because she was carrying a _________ across the finish line.

4 . Personal Forgiveness

Taking responsibility for mistakes is a positive step, but don’t beat yourself up about them. To err (犯错) is human.     1     You can use the following writing exercise to help you do this.

In a journal or on a piece of paper, put the heading “Personal strengths.”     2     Are you caring? Creative? Generous? A good listener? Fun to be around? They don’t have to be world-changing, just aspects of your personality that you’re proud of.

At the top of a second page, put the heading “Acts of kindness.” On this one, list all the positive things you’ve done for others. It might be the time when you helped a friend with their homework, when you did the ironing without being asked, or when you baked cookies after the family had had a tiring day.     3    

You could ask a friend or family member to help add to your list.     4     That way, you could exchange thoughts on what makes each of you special and the aspects of your personality that shine through. In fact, don’t wait until you’ve made a mistake to try this — it’s a great way to boost self-confidence at any time.

It’s something of a cliché (陈词滥调) that most people learn not from their successes but their mistakes. The thing is, it’s true.     5     We’ re all changing and learning all the time and mistakes are a positive way to develop and grow.

A．A little self-forgiveness also goes a long way.

B．Now list all the characteristics you like about yourself.

C．They might even like to have a go at doing the exercise.

D．It’s just as important to show yourself some forgiveness.

E．It doesn’t mean you have to ignore what’s happened or forget it.

F．Whatever it is, no matter how small it might seem, write it down.

G．Whatever the mistake, remember it isn’t a fixed aspect of your personality.

5 . When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.

After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.

The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.

He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.

Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.

“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”

1. What can we learn about John from the first two paragraphs?

A．He was fond of traveling.	B．He enjoyed being alone.
C．He had an inquiring mind.	D．He longed to be a doctor.

2. Why did John put the sludge into the tanks?

A．To feed the animals.	B．To build an ecosystem.
C．To protect the plants.	D．To test the eco-machine.

3. What is the author’s purpose in mentioning Fuzhou?

A．To review John’s research plans.	B．To show an application of John’s idea.
C．To compare John’s different jobs.	D．To erase doubts about John’s invention.

4. What is the basis for John’s work?

A．Nature can repair itself.	B．Organisms need water to survive.
C．Life on Earth is diverse.	D．Most tiny creatures live in groups.

8 . Indoor plants might look as if they just sit around not doing much, but in many ways they are the unsung heroes of the home.     1    , but studies have shown that they can promote people’s wellbeing by improving their mood (心情), reducing stress and helping their memory. What’s more, indoor plants are easy to look after and are not very expensive.

What are indoor plants?

Indoor plants, also known as houseplants or pot plants, are plants that like to grow indoors. Many of these species (物种) are not ideally suited to growing outside in the UK, especially in the winter.     2    .

Why are indoor plants good for you?

Will Spoelstra, who works at the Royal Botanic Gardens, says, “    3    . I find during the winter months, plants around the house can really lift your mood.” Several studies have backed this up and found that indoor plants can improve creativity, focus and memory. There is also research showing that pot plants can clean the air around them by removing harmful gases, such as carbon dioxide. They also remove some harmful chemicals from paints or cooking.     4    .

Which plants can you grow?

Aloe vera, peace lilies and spider plants are some of the species that are easy to grow indoors. You can buy plants from supermarkets, garden centres or online. Younger plants are often cheaper than fully grown ones, and you get to care for them as they mature — which is part of the joy of owning plants. “    5    ,” Spoelstra says. “It can bring a new interest and focus into people’s lives and help to make the link between home and nature.”

A．All plants are different

B．Not only do they look beautiful

C．There are many benefits to growing plants indoors

D．Instead, they grow better inside, where it is warmer

E．Plants like peace lilies and devil’s ivy are among the best

F．Changing the pot of your plant from time to time will also help

G．Learning about the requirements of each plant can be very rewarding

9 . Living in Iowa and trying to become a photographer specializing in landscape (风景) can be quite a challenge, mainly because the corn state lacks geographical variation.

Although landscapes in the Midwest tend to be quite similar, either farm fields or highways, sometimes I find distinctive character in the hills or lakes. To make some of my landscape shots, I have traveled up to four hours away to shoot within a 10-minute time frame. I tend to travel with a few of my friends to state parks or to the countryside to go on adventures and take photos along the way.

Being at the right place at the right time is decisive in any style of photography. I often leave early to seek the right destinations so I can set up early to avoid missing the moment I am attempting to photograph. I have missed plenty of beautiful sunsets/sunrises due to being on the spot only five minutes before the best moment.

One time my friends and I drove three hours to Devil’s Lake, Wisconsin, to climb the purple quartz (石英) rock around the lake. After we found a crazy-looking road that hung over a bunch of rocks, we decided to photograph the scene at sunset. The position enabled us to look over the lake with the sunset in the background. We managed to leave this spot to climb higher because of the spare time until sunset. However, we did not mark the route (路线) so we ended up almost missing the sunset entirely. Once we found the place, it was stressful getting lights and cameras set up in the limited time. Still, looking back on the photos, they are some of my best shots though they could have been so much better if I would have been prepared and managed my time wisely.

1. How does the author deal with the challenge as a landscape photographer in the Midwest?

A．By teaming up with other photographers.	B．By shooting in the countryside or state parks.
C．By studying the geographical conditions.	D．By creating settings in the corn fields.

2. What is the key to successful landscape photography according to the author?

A．Proper time management.	B．Good shooting techniques.
C．Adventurous spirit.	D．Distinctive styles.

3. What can we infer from the author’s trip with friends to Devil’s Lake?

A．They went crazy with the purple quartz rock.

B．They felt stressed while waiting for the sunset.

C．They reached the shooting spot later than expected.

D．They had problems with their equipment.

4. How does the author find his photos taken at Devil’s Lake?

A．Amusing.	B．Satisfying.
C．Encouraging.	D．Comforting.
