Who wants to carry a bulky bag to school? No children. Nobody wants one shoulder to be lower than the other, and paining（疼痛）too. In India, most of us would look at the reduction（減少）of textbooks as a way out. But in a country like America, there are always more choices. A company called goReader has created a "school bag" which is the size of a laptop computer（筆記本電腦）, weighing about 2.5 kg. The goReader has a color screen and can "hold" all the textbooks that a student may need, says a report in 'The Asian Age' newspaper.

The company plans to work closely with the publishers（出版商） of textbooks so that these books can be supplied on the Internet. All the students will have to do is to download（下載） their textbooks. Making notes and marking important parts of a lesson can be done just as lots of students have done on their textbooks before.

At present, the plan is being tested out in a university. Richard Katzmann, the owner of the company is having his creation tested at Chicago's DePaul University, where he studied. Does that mean it is goodbye to the new paper, and the smell of the black ink?

1. What does the underlined word “bulky” in the first line mean?

A. light B. small C. big and heavy D. old

2. What would Indians do to solve（解決）the problem?

A. They would reduce the textbooks.

B. They would tell the parents to help students.

C. They would tell the teachers to help students.

D. They would take students to school by bus.

3.The writer may think that Americans have a ________ way to solve the problem.

A. more stupid B. worse

C. better D. quicker

4. The goReader may be a machine ________.

A. that can work as a teacher

B. that can be used as textbooks

D. that can hurt students

Have you ever wondered how and why a fall leaf changes color? We first have to understand what leaves are and what they do.

Plants are the world’s food factories. Plants take water from the ground and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖). Glucose is a kind of sugar. Using it as food, plants get energy and grow. Plants using sunlight to turn water and CO2 into sugar is called photosynthesis(光合作用). ChlorophyII helps photosynthesis. It gives plants their green color.

As summer ends and autumn comes, the days get shorter and shorter, and trees ＂know＂ to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food — making factories. As the green chlorophyII disappears from the leaves, we begin to see yellow and orange leaves. These colors have been in the leaves all the time. We just can’t see them in the summer, because they are covered up by the green chlorophyII.

The bright reds and purples we see in leaves are made mostly in autumn. In some trees, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color. The brown color of trees is made from waste left in the leaves. It is mixture(混合物) of all these things. It makes the beautiful leaves during autumn.

4.Which of the following is NOT true according to the passage?

B. Leaves turn red because sunlight and the cool nights of autumn turn glucose into a red color.

C. We can’t see yellow or orange leaves in summer because the two colors are not in leaves.
