1 . My husband, our children and I have had wonderful camping experiences over the past ten years.

Some of our _______ are funny, especially from the early years when our children were little. Once, we _______ along Chalk Creek. I was _______ that our 15-month-old boy would fall into the creek (小溪). I tied a rope around his waist to keep him near to our spot. That lasted about ten minutes. He was _______, and his crying let the whole campground know it. So _______ tying him up, I just kept a close eye on him. It _______ — he didn’t end up in the creek. My three-year-old, however, did.

Another time, we rented a boat in Vallecito Lake. The sky was clear when we _______, but storms move in fast in the mountains, and this one quickly _______ our peaceful morning trip. The _______ picked up and thunder rolled. My husband stopped fishing to ____________ the motor. Nothing. He tried again. No ____________. We were stuck in the middle of the lake with a dead motor. As we all sat there ____________, a fisherman pulled up, threw us a rope and towed (拖) us back. We were ____________.

2 . Like most of us, I try to be mindful of food that goes to waste. The arugula (芝麻菜)was to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads with what I threw out.

In a world where nearly 800 million people a year go hungry, “food waste goes against the moral grain,” as Elizabeth Royte writes in this month’s cover story. It’s jaw-dropping how much perfectly good food is thrown away — from “ugly” (but quite eatable) vegetables rejected by grocers to large amounts of uneaten dishes thrown into restaurant garbage cans.

Producing food that no one eats wastes the water, fuel, and other resources used to grow it. That makes food waste an environmental problem. In fact, Royte writes, “if food waste were a country, it would be the third largest producer of greenhouse gases in the world.”

If that’s hard to understand, let’s keep it as simple as the arugula at the back of my refrigerator. Mike Curtin sees my arugula story all the time — but for him, it's more like 12 bones of donated strawberries nearing their last days. Curtin is CEO of DC Central Kitchen in Washington, D.C., which recovers food and turns it into healthy meals. Last year it recovered more than 807,500 pounds of food by taking donations and collecting blemished (有瑕疵的) produce that otherwise would have rotted in fields. And the strawberries? Volunteers will wash, cut, and freeze or dry them for use in meals down the road.

Such methods seem obvious, yet so often we just don’t think. “Everyone can play a part in reducing waste, whether by not purchasing more food than necessary in your weekly shopping or by asking restaurants to not include the side dish you won’t eat,” Curtin says.

1. What does the author want to show by telling the arugula story?

A．We pay little attention to food waste.	B．We waste food unintentionally at times.
C．We waste more vegetables than meat.	D．We have good reasons for wasting food.

2. What is a consequence of food waste according to the test?

A．Moral decline.	B．Environmental harm.
C．Energy shortage.	D．Worldwide starvation.

3. What does Curtin’s company do?

A．It produces kitchen equipment.	B．It turns rotten arugula into clean fuel.
C．It helps local farmers grow fruits.	D．It makes meals out of unwanted food.

4. What does Curtin suggest people do?

A．Buy only what is needed.	B．Reduce food consumption.
C．Go shopping once a week.	D．Eat in restaurants less often.

9 . The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.

The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.

One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.

In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.

Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.

1. What is the first paragraph mainly about?

A．A new study of different plants.

B．A big fall in crime rates.

C．Employees from various workplaces.

D．Benefits from green plants.

2. What is the function of the sensors printed on plant leaves by MIT engineer?

A．To detect plants’ lack of water

B．To change compositions of plants

C．To make the life of plants longer.

D．To test chemicals in plants.

3. What can we expect of the glowing plants in the future?

A．They will speed up energy production.

B．They may transmit electricity to the home.

C．They might help reduce energy consumption.

D．They could take the place of power plants.

4. Which of the following can be the best title for the text?

A．Can we grow more glowing plants?

B．How do we live with glowing plants?

C．Could glowing plants replace lamps?

D．How are glowing plants made pollution-free?

10 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

1. Why are race walkers conditioned athletes?

A．They must run long distances.

B．They are qualified for the marathon.

C．They have to follow special rules.

D．They are good at swinging their legs.

2. What advantage does race walking have over running?

A．It’s more popular at the Olympics.

B．It’s less challenging physically.

C．It’s more effective in body building.

D．It’s less likely to cause knee injuries.

3. What is Dr. Norberg’s suggestion for someone trying race walking?

A．Getting experts’ opinions.

B．Having a medical checkup.

C．Hiring an experienced coach.

D．Doing regular exercises.

4. Which word best describes the author’s attitude to race walking?

A．Skeptical.	B．Objective.
C．Tolerant.	D．Conservative.
