【题目】B

Many areas of cropland in Bangladesh(孟加拉国) are becoming unfit for farming. The land is becoming salty. It is a big problem for the small country. More than 155 million people live in Bangladesh. Growing crops is the most common way Bangladeshis support themselves.

Farmers in the country are learning to grow vegetables in so-called "vertical gardens." The soil in these gardens is better because heavy rains have removed much of the salt.

A vertical garden is easy to make. Villagers fill containers with good soil and natural fertilizers. They put the containers on bricks so they are off the ground. They add pieces of the bricks to the soil to help water flow and drain.

The farmers cut small holes into the sides of the containers. This permits vegetables with short roots a place to grow. Vegetables with long roots grow on top of the container. One bag of soil can produce up to eight kilograms of vegetables in one season.

Villagers also grow vegetables in containers made from large, thin pieces of plastic supported by bamboo. This "vertical tower" measures more than a meter wide. Each of these towers can produce more than 100 kilograms of vegetables. It costs about $12-$13 to build.

The village of Chandipur is in southwestern Bangladesh. Pumpkins and other gourds(葫芦) grow on vines on top of small homes. The vegetables get the food they need from soil placed in containers on the ground.

Shobitha Debna is a 35-year-old farmer in the village. Her garden space is very small. But she is able to grow hundreds of kilograms of vegetables each season.

She says she grows gourds, including pumpkin, as well as green beans, red amaranth, beets, carrots, cauliflower and more.

Ms. Debna depends on the vegetables to earn money. She makes a few dollars a day.

This kind of farming is new in Chandipur. But it may spread across the country.

【题目】C

Researchers are now using three-dimensional, or 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.

Surgeons regularly use digital images to explore the heart in close detail. But no two human hearts are alike. This led Matthew Bramlet to create exact heart models from those images. Dr. Bramlet is a pediatric or children's heart expert at the University of Illinois College of Medicine. He says the 3-D models show information he cannot get any other way.

A 3-D printer uses images from a digital display to create a physical model of a human heart. Matthew Bramlet says doctors can use the model, in his words, "to understand the anatomy(解剖) for the first time."

Pictures from medical tests like CAT scan or MRI are sent to a 3-D printer to create a heart in a plaster or clay form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail.

Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But, the 3-D printed model showed several defects or problems that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3-D model. He added that 3-D heart models saves time during heart operations.

Matthew Bramlet continues to research the technology. He is working with the National Institutes of Health to build a 3-D library that includes heart models and images that others can use.

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

3 Ways to Keep Tabs on Your Weight

1. WAIST-TO-HIP RATIO

Measuring your waist-to-hip ratio is an accurate way of monitoring changes to your body shape. 【1 Grab a tape measure and wrap it around your middle, where your belly button sits. Then do the same around your hips’ widest point. 【2 A ratio of above 0.8 indicates you could be carrying an unhealthy amount of abdominal fat.

2. BODY MASS INDEX (BMI)

It’s thrown around a lot these days but your BMI is a number that indicates your weight in relation to your height. 【3 A BMI above this can mean an increased risk of heart disease and type 2 diabetes, both common weight-related conditions. What’s your BMI? 【4 Easier still, Google “BMI Calculator” and enter your measurements.

3. WAIST MEASUREMENTS.

Your essential organs liver, spleen, heart, kidneys and lungs are located just above the waist region. Carrying any extra weight around your waist brings additional burden to these organs, making it harder for them to work efficiently. 【5 For men, try to stay under 94cm and for women 80cm.

A. How can we do it?

B. How do you do it?

C. How big is too big?

D. A healthy BMI is between 18.5 and 25.

E. A new standard of BMI will come out soon.

F. Then divide the waist measurement by the hips measurement.

G. Simply divide your weight in kilograms by your height in metres squared.
