Runners in a relay race pass a stick in one direction. However, merchants（商人） passed silk, gold, fruit, and glass along the Silk Road in more than one direction. They earned their living by traveling the famous Silk Road.
The Silk Road was not a simple trading network. It passed through thousands of cities and towns. It started from eastern China, across Central Asia and the Middle East, and ended in the Mediterranean Sea. It was used from about 200 B.C. to about 1300 A.D., when sea travel offered new routes. It was sometimes called the world’s longest highway. However, the Silk Road was made up of many routes, not one smooth path. They passed through what are now 18 countries. The routes crossed mountains and deserts and had many dangers of hot sun, deep snow and even battles. Only experienced traders could return safe.
The Silk Road got its name from its most prized product. Silk could be used like money to pay taxes or buy goods. But the traders carried more than just silk. Gold, silver, and glass from Europe were much found in the Middle East and Asia. Horses traded from other areas changed farming practices in China. Indian merchants traded salt and other valuable goods. Chinese merchants traded paper, which produced an immediate effect on the West. Apples traveled from central Asia to Rome. The Chinese had learned to graft(嫁接) different trees together to make new kinds of fruit. They passed this science on to others, including the Romans. The Romans used grafting to grow the apple. Trading along the Silk Road led to world-wide business 2,000 years before the World Wide Web.The people along the Silk Road did not share just goods. They also shared their beliefs.

The Cuban iguana is a species of lizard（蜥蜴） of the iguana family． It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards． This species with red eyes and a thick tail is one of the largest lizards in the Caribbean．
The Cuban iguana is primarily herbivorous; 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses． However, Cuban iguanas occasionally consume animal matter, and individuals have been observed eating the dead flesh of birds, fish and crabs, The researchers wrote that quite a few people on Isla Magueyes could have caused this incident．
The Cuban iguana is distributed throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population booming on Isla Magueyes, Puerto Rico． It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs． Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles． To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti （仙人掌）．
In general the species is in decline, more quickly on the mainland than on the outlying islands． One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests． Although the wild population is in decline, the numbers of iguanas have been sharply increased as a result of captive-breeding（圈养） and other conservation programs．．The underlined word "herbivorous" （Paragraph 2） probably means．
| A．dangerous | B．gentle |
| C．plant-eating | D．flesh-eating |

My 16-year-old son, Anton, had gone to the local swimming hole． Most of the kids swim there, and there are plenty of rocks for them to use as safe harbors, so I had no fears for his safety．
Still, the firefighter's first words "You need to come up here to the Stillwater River" made me catch my breath, and his follow-up words gave me relief: “ Your son is OK．”
When I got to the river, I immediately saw the firetruck, ambulance and Anton, wrapped with a towel about his shoulders, sitting quietly on a low platform of the fire engine．
I hurried over to him． "You OK?"I asked．
”Yeah," was all he said． But my eyes begged for an explanation, I didn't get it from my son, however, who tends to play his cards close to his vest．
The story was this: A woman was being swept under water． Hearing the cries, Anton and his friend Tyler, without hesitation, swam out to her, and brought her safely to shore．
In an age in which the word "hero" is broadcast with abandon and seemingly applied to anyone who make it through the day, I realized the real thing in my son． The teens are stubborn and self-centred, but that didn't mean they have no desire to do good．
Still shocked by my son's daring, I drove him home． Along the way, I tried to dig out some more information from him - but he had precious little to say． The only words he said were,
”What's for supper?"
I spent some time alone that evening, thinking about the tragedy that might have been． The next morning, when Anton got up, I half expected him to tell me the story． But all he did was toast some bread, pull himself together, and head for the door to start a new day． Watching from the window,1 was reminded that still water often runs deep．Why did the mother allow her son to swim there?
| A．He was an excellent swimmer． |
| B．The water of the river is shallow． |
| C．He was old enough to swim． |
| D．The rocks can be of help if there's danger． |
The underlined part "who tends to play his cards close to his vest" probably means
| A．Anton is a boy fond of swimming with other kids |
| B．Anton is unwilling to tell others what he thinks |
| C．Anton always has a desire to help others |
| D．Anton seldom changes his mind |
In the mother's eyes, what her son did was
| A．dangerous but interesting |
| B．unexpected and courageous |
| C．meaningful but difficult |
| D．awful and absurd |
What might be the best title for the passage?
| A．My Son, My Hero | B．Anton, A Silent Boy |

Up to two-fifths of a food crop is often wasted because it is “ugly”, a report on food waste has shown.
Produce grown in the UK that does not meet retailer(零售商) standards on appearance is often given to animals or thrown out even though it is healthy to eat.
The report from the UK’s global food security program also showed that the average household throws away more than 5kg of food a week, and nearly two-thirds of that waste is avoidable.
The waste costs £ 480 a year per household on average, and £ 680 per family.
Households throw away a fifth of the food they buy, wasting it for reasons ranging from cooking too much to not using it before it goes bad, the study showed.
Consumption is the top area where food is wasted in the UK, the study said.
Farmers respond to consumer demands for high-quality food with standards that can lead to the crop being wasted. Some supermarkets have started marketing “odd shapes and sizes” of fruit and vegetables, though.
Also, more UK consumers are prepared to accept “ugly” fruit and vegetables, amid concerns over sustainability(可持续发展) and food prices, the research said.
In developing countries, much of the loss of food occurs during post-harvesting storage, processing and packaging.
Tackling waste globally is necessary to feed a growing world population sustainably. One in eight people worldwide doesn’t have enough food, the report said.
Around a third of food produced globally is lost or wasted.
Professor Tim Benton, an expert on food security at the University of Leeds, said: “Over 5 million people in the UK live in poverty, where basic food provision is a daily challenge.”
Nearly 400,000 people used food banks last year, according to the Trussell Trust.
“At the same time, 15 million tons of food is wasted annually, with nearly half thrown away within UK households. Reducing the scale(范围) of losses and waste throughout the food system is a crucial step.”
The report highlights priorities(优先事项) for research to help reduce food waste, including improving harvesting and packaging technologies and seasonal weather prediction. Food waste in developing nations is mainly due to .
| A．fast growing populations |
| B．huge demand for high-quality foods |
| C．poor technology in food industries |
| D．people’s lack of concern about food shortages |
We can conclude from the article that .
| A．over half of the food produce in the UK is wasted within households |
| B．“ugly” fruits and vegetables are becoming more and more popular in the UK |
| C．avoiding food waste could, by itself, solve food shortage problems around the world |
| D．developing better farming and packaging technologies is key to reducing food waste |
Which of the following statements might Professor Tim Benton agree with?
| A．British farmers should keep up with their high growing standards. |
| B．The number of people living in poverty is growing too fast in Britain. |
| C．There is still much to do to improve British people’s awareness of food sustainability. |
| D．British supermarkets should be encouraged to sell food of odd shapes and sizes. |
What is suggested in the report?
| A．Cutting food prices. |
| B．Using different approaches to reduce food waste. |
| C．Improving the appearance of food. |
| D．Cooking at home more often. |
Here is a task for you: try to make as many kinds of facial expressions as you can. How many can you come up with?
Facial expressions are like a window to your emotions inside. Scientists used to believe that we only have six basic emotions-happy, sad, fearful, angry, surprised and disgusted-and ,therefore, each of our facial expressions falls into one of the six categories.
But it turns out that this is just the tip of the iceberg. In a recent study, scientists from Ohio State University, US, mapped 21 different facial expressions, more than tripling(是……的三倍) the original number, reported Science Daily.
Restricting emotions to just six categories is like “painting only using primary colors”, said Aleix Martinez, the lead researcher. He believed that human emotions are much richer than that, which is why he and his team decided to use advanced computer technology for further investigation.
In the experiment, scientists photographed 230 volunteers-100 male and 130 female-while they made faces in response to different words such as “you smell a bad odor(气味)”. They then closely studied the images by examining key muscles on volunteers’ faces, such as the corners of the mouth or the outer edge of the eyebrow, and finally identified 21 different expressions. These included what seem to be contradictory emotions such as “happily disgusted” and “sadly angry”, which scientists call “compound(混合的) emotions”.
Take “happily disgusted” as an example.” Putting on a happy face is usually done by drawing up the cheeks and smiling while a disgusted face often involves a scrunched-up(皱起的) nose and eyes. So the “happily disgusted” emotion created an expression that combined the smile of happy with the scrunched-up eyes and nose of disgusted. It was the emotion test subjects felt when something “gross(恶心的)” happened that was also funny-for example, when people spill(洒出) a lot of food on their clothes.
Similarly, “happily surprised” is an expression for receiving unexpected good news. “Sadly angry” is the face we make when someone we care about makes us angry.
According to Martinez, the researchers’ next step is to study the pathways and chemicals in the brain that activate(激活) and recognize those emotions. He believes that this could lead to effective treatments for people who suffer from conditions such as Post-Traumatic Stress Disorder(PTSD,创伤后应激障碍), which involves a lack of recognition of other people’s emotions.The underlined part “this is just the tip of the iceberg” in Paragraph 3 probably means .
| A．this is a truth known to us all |
| B．this is the total amount of something |
| C．this is easily seen or discovered |
| D．this is only the smallest and most obvious part of something |
How does the author explain the definition of “compound emotions” in the article?
| A．With comparisons. |
| B．Through examples. |
| C．Through cause and effect analysis. |
| D．By presenting research findings. |
According to the article, people are likely to become happily disgusted when .
| A．they receive unexpected good news |
| B．someone they don’t care about makes them happy |
| C．something unpleasant but also funny happens |
| D．they successfully escape from a dangerous situation |
What can we conclude from the article?
A. There are several contradictory emotions we tend to overlook.
B. Females have more contradictory emotions than males do.
C. The chemicals in the brain that activate emotions are easy to identify.
D. Martinez’s next goal is to find an effective cure for people who suffer from PTSD.
