【題目】C

A Swiss airplane powered only by energy from the sun left from Abu Dhabi early on March 9. Its creators hope the plane will make the first around-the-world journey without any fuel.

The plane is called Solar Impulse 2. It has one seat and is made from carbon fiber. The plane weighs only as much as a car but its wings are wider than a Boeing 747. The plane’s wings stretch 72 meters across.

Those wings include 17,000 solar units, or cells, that capture the sun’s energy. The energy allows the plane to fly day and night.

Two Swiss scientists built the plane. Bertrand Piccard is also an explorer who made the first non-stop flight around the world in a balloon. Borschberg is an engineer and trained fighter pilot.

The scientists say they are not trying to change the airplane industry. Instead, they want to show that new energy sources and technologies can achieve what some say is impossible.

“We want to show we can fly day and night in an aircraft without a drop of fuel,” Mr. Piccard said.

Some parts of the trip will require the pilots to be in the tiny plane for five to six days and nights in a row. So it is good that the pilot’s seat is also a toilet.

The plane’s route begins in the United Arab Emirates. The pilots also plan stops in Oman, India, and China. They will cross the Pacific Ocean, stop in the United States, and continue over southern Europe or North Africa. They plan to arrive back in the United Arab Emirates in late July or early August.

【1】Which of the following is the plan stops of the tour made by the solar-powered plane?

A. Abu Dhabi---Oman---China---the United States--- southern Europe ---the United Arab Emirates

B. the United Arab Emirates--Oman--- India---the United States--- North Africa--- Abu Dhabi

C. the United Arab Emirates--Oman--- India ---China---southern Europe --- Abu Dhabi

D. Abu Dhabi--Oman--- India ---China---the United States--- the United Arab Emirates

【2】What can be inferred from the passage?

A. The plane’s wings include 17,000 solar units, or cells, that capture the sun’s energy.

B. The plane weighs only as much as a car but its wings are narrower than a Boeing 747.

C. Bertrand Piccard is one of the co-builders of the plane.

D. The scientists are trying to change the airplane industry.

【3】What’s the best title of the passage?

A. Solar Powered Plane Starts World Tour

B. A Plane Powered By Solar Energy

C. A Plane’s Route Begins in the United Arab Emirates

D. A Tour Around the World

【題目】B

Many areas of cropland in Bangladesh(孟加拉國) 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(葫蘆) 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.
