Imagine yourself in a small airplane 3,300 meters above the ground. The engines roar in your ears as you move towards the open door. Then you' re outside, falling with the wind whipping past your ears. As the ground rushes up at you, you open your parachute. 1.. All in all, you were in free fall for only 30 seconds---the longest 30 seconds of your life.

2.. However, a growing number of adventurers are taking the risk. Obviously skydiving isn't something you can just try, like fishing or bowling. So, if you want to attempt the sport, you'll need to go to ground school.

3.. The course is taught by licensed skydiving instructors who have been jumping for years.

They'll teach you how to keep your body position stable. You'll also learn to be constantly aware of your altitude and, most importantly, when to open your parachute.

Once you' re through with ground school, it's time to get up in the air. 4.. Two instructors always jump with the person, ready to pull the student's parachute open if he or she freezes up.

5.. It certainly seems dangerous when you' re watching someone fall at 200 km/ hr. But, if you believe the statistics, skydiving is actually safer than driving, with one fatality (死亡) occurring in approximately 60, 000 jumps. Moreover, most enthusiasts agree all fear stops the second your feet leave the plane, and when you land, the only thought in your mind is, "Wow! I want to do that again!"

A. However, a new jumper never jumps alone.

B. It takes years to forget the taste of fear from skydiving.

C. No doubt, you're thinking skydiving is a dangerous sport.

D. It explodes over your head, pulling you back and upwards.

E. For most of us, skydiving is something we only see in the movies.

F. Ground school is where you learn to jump, without leaving the ground.

G. Skydiving is the sport of jumping out of an airplane and falling freely through the air.

Imagine a house that keeps itself warm in the wintertime. Think of the savings in terms of fuel bills and unfriendly emissions. Such houses in fact exist, called “passive houses”. The concept of these highly energy-efficient buildings took root in the 1990s, before slowly consolidating as a niche construction (生态位构建) concept in the 2000s. Are passive houses now actively moving into the mainstream as sustainable buildings?

For Brian McGarry, an economics lecturer who built a family house based on passive housing criteria in the Pyrenees this year, the arguments look convincing. As his first full winter in the low energy house draws in, we asked him to keep us informed. Do passive houses work?

I had never heard of a passive house in February 2012, when I purchased a plot of land. Nor did I expect that I would be persuaded to build a pre-constructed, custom-designed house based on energy-efficient passive house criteria. It promised to be easier and quicker to build, cheaper to run, and more comfortable to live in. The objective was to incorporate the fundamental concepts of passive energy management into my project: an airtight and highly insulated building envelope; large southfacing double or triple-glazed windows (if possible, filled with argon gas) that passively capture the energy of the sun; a heat recovery ventilation system to provide fresh air; and a simple, low-cost heating system consisting of a modern wood-burning stove, a bathroom heater and a portable radiator backup for when the sun doesn’t shine and temperatures decline. No significant

limitations were placed on the design, and it had excellent environmental credentials. Moreover, the cost was no more than a conventional build.

After six months in use, the house is proving to be both cheap to run and remarkably comfortable–staying cool in the hot summer was effortless, as long as the windows were shuttered or shaded from the sun. Nowstaying warm in the cold, high-altitude December climate also seems easy, so far.

Winter arrived in force in the Pyrenees in November, with abundant snowfalls and temperatures as low as minus 8° Celsius. Though early days, the house has responded well: the stove is lit during cold evenings but the portable radiator has not yet been needed. This type of construction seems not only to make economic andenvironmental sense, but to enhance our quality of life, too.

1.We can learn from Paragraph one that passive houses __________.

A. consume extra energy to keep warm in winter and cool in summer

B. had been introduced for a decade before the birth of the theory

C. appeal to both the self-builders and those constructors

D. refer to a certain house comfortable, costly and also pleasing

2.Regarding the passive energy management, the houses have characteristics EXCEPT _______

A. using south-facing windows to take in solar energy

B. Providing energy for taking a shower when it’s rainy

C. supplying fresh air with a special heat recovery system

D. placing more demands and restrictions on the design

3.How did Brian McGarry find his self-built passive house?

A. very unaffordable

B. Energy-consuming

C. comfortable to live in

D. Awkward to use

4.What is the writer’s attitude towards the passive housing?

A. supportive　　　 B. critical

C. oppositive　　　 D. doubtful

When she was studying to become a scientist, Megan Strauss rode in a small airplane to study giraffes. While a pilot flew over the Serengeti in Tanzania, Africa, the researchers looked down carefully and counted giraffes.

"I am always amazed how easily we can spot warthogs and other small animals, yet we sometimes have trouble seeing giraffes. Giraffes are slender in shape, and they may not throw a good shadow, " says Dr. Strauss, who has since become a wildlife scientist.

The Serengeti is about the size of Vermont, a state in the northeastern US, so the scientists could not study the entire area. Instead, they surveyed three areas where giraffes were studied in the 1970s. As they expected, they saw far fewer of these animals.

To find out if lions had been killing more giraffes in recent years, the team looked at the survival of young giraffes. Lions kill more young giraffes than adults, but the team found no decrease in young giraffes' survival after they are born, compared with the 1970s.

The team then looked at whether too many giraffes were being killed by parasites(寄生虫).The researchers counted parasite eggs in giraffe droppings, and they found too few to harm the giraffe population.

They looked into whether poachers (盗猎者)were killing too many giraffes. Two of the areas they studied are where giraffe meat is sometimes sold in local markets. Poachers catch more adult males than other giraffes. Researchers spotted too few males compared with females in those two areas, a sign of poaching.

When the food supply is short, the environment supports fewer giraffes and the females have fewer young giraffes. A lot of new trees have grown in the Serengeti, but many are a type that giraffes do not like to eat. The researchers found fewer young giraffes today than in the 1970s compared with the number of adult females, a sign that food was in short supply.

Dr. Strauss is working on an environmental education program for Tanzania including books for students. These materials will educate Tanzanians and help them to help giraffes. As knowledge grows and changes are made, they hope the giraffe population will increase.

1.What did Dr. Strauss find while studying giraffes in the Serengeti?

A.It was too costly to study giraffes.

B.It was hard to spot giraffes from the air.

C.The number of giraffes had increased slowly.

D.Giraffes lived in smaller areas than in the 1970s.

2.How did the team study the lion-giraffe relationship?

A.By analyzing giraffe droppings.

B.By comparing young giraffes with adults.

C.By comparing male giraffes and females.

D.By surveying the survival of young giraffes.

3.What is Dr. Strauss doing to help giraffes?

A.She is founding a national park in Tanzania.

B.She is counting giraffes in the entire Serengeti.

C.She is educating students to write about giraffes.

D.She is raising environmental awareness in local people.

People living more than three thousand meters above sea level find it difficult to raise vegetables all year long. People living in the highlands of Peru and Bolivia, for example, cannot grow vegetables outdoors during the months of May through September. It is very cold in the highlands at that time of year. If traditional farming methods are used, vegetables will not survive.

However, there is another way to grow vegetables throughout the year in cold areas. It is a method of gardening developed by a private agency called World Neighbors. The method uses “hot houses” built below ground. A hot house is a building covered with plastic or glass in which vegetables or flowers are grown. The traditional hot house is built above ground.

The air temperature is cold in the highlands of Peru and Bolivia during the winter. But, the winter sun is hot. So, World Neighbors advises farmers there to build hot houses below ground. The design is simple. The material does not cost much. Here is how World Neighbors says to build it: Dig a hole two and one-half meters wide and six meters long. Make it about two meters deep. Build wall with a door in one end of the hole. Dig steps from the ground down to the door.

Now, build a wall along the top edge of the hole. Make it about one-half meters tall. Earth bricks work fine. Build two shorter walls on the ends. These will be uneven; one side will be as high as the existing wall. The other side will be at ground level. Leave a small opening in each of these sloping walls. This prevents the hot house from becoming too hot. Now, make the roof. Build a wood frame. Cover it with clear plastic. Connect it to the brick walls.

The underground hot house we have described is large enough for two raised vegetable beds. Each is one meter wide and six meters long. Each is seeded and watered just as if it were in a garden above ground.

The dirt walls protect the growing plants from the cold. The clear plastic roof permits the sun’s heat to enter. At night, the roof should be covered with straw. This helps prevent cold air from entering. An under ground hot house this size will provide enough vegetables for one family. Groups needing more vegetables can make it bigger.

66. If you lived in Peru, you _______.

A. should raise the special kinds of vegetables that can endure cold

B. could not plant at all

C. had to work out some new unusual plans

D. would not have many vegetables to eat

67. To our surprise, the “hot houses” invented by World Neighbors are _______.

A. covered with a transparent plastic ceiling

B. built under ground

C. quite small

D. hotter than traditional ones

68. The hot house can be kept warm by using _______.

A. a big oven  B. an electricity heater

C. the heat of the earth’s interior   D. the sun shine

69. The measure to prevent the hot house from becoming too hot is to _______.

A. make the roof sloped B. dig holes on the walls

C. make the wall not vertical D. make the walls shorter than the ground level

70. According to the passage, the method suggested by World Neighbors is _______.

A. new and difficult      B. uneasy to explain

C. at trial step D. simple and practical
