Homework is a major part of going to school: It’s your teachers’ way of evaluating how much you understand what's going on in class. 1. Luckily, you can do a few things to make homework less burden.

Be sure you understand the homework.

Write your homework down in your notebook or day planner if you need to. 2. It’s much easier to take a minute to ask the teacher during or after class than to struggle to remember later that night!

Use any extra time in school.

Many schools have study halls that are specifically designed to allow students to study. It’s tempting(诱惑人的) to hang out with friends during study periods or unstructured (松散的) time. 3. .

Take a break.

4. So take some breaks while doing your homework. Sitting for too long without stretching or relaxing will make you less productive than if you stop every so often. Taking a 15-minute break every hour is a good idea for most people.

5. .

If you don't finish your homework during school, think about how much you have left and what else is going on that day, and then budget your time. Most high-school students have between 1 and 3 hours of homework a night. If it’s a heavy homework day and it seems like you’ve got an assignment in every subject but gym and lunch, you’ll need to devote more time to homework. It’s a good idea to come up with some kind of homework schedule, especially if you are involved in sports or activities or have an after-school job.

A. And it helps digest important concepts.

B. Once your homework is done, you can check over it if you have extra time.

C. Plan yourself.

D. But the more work you can get done in school, the less you'll have to do that night.

E. Don't be afraid to ask questions about what's expected in your homework.

F. Settle down to homework.

G. Most people's attention spans (跨度) aren't very long.

One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem, while the student claimed a perfect score. I was elected as their arbiter（仲裁人）. I read the examination problem: “Show how it is possible to determine the height of a tall building with the aid of a barometer（气压计）. ”The student had answered; "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. The length of it is the height of the building.”

The student had really answered the question completely, but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and dashed off one, which read：“Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula（公式）to calculate the height of the building.”

At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others, and then added, "Probably the best is to take the barometer to the administrator and said to him, ‘Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.”,

Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.

The name of the student was Bohr who later was famous all over the world. He won the Nobel Prize for Physics in 1922.

1.The student got a zero at the beginning because _____.

A. the teacher wasn't satisfied with him

B. his answer wasn't complete or correct

C. the teacher didn't fully understand his answer

D. his answer didn't show his knowledge of physics

2.We know from the passage that _____.

A. the student knew the expected answer

B. the administrator told Bohr the height

C. the author preferred Bohr's last answer

D. the teacher was a very stubborn person

3.We can learn from the passage that _____.

A. instructors can teach students how to think

B. arbiters can help students to get high scores

C. students should be given more freedom in thinking

D. teachers should make students use physical formulas

4.What was Bohr's attitude toward his schooling?

A. Optimistic B. Critical C. Approving D. Neutral

Part III Reading Comprehension （30 marks）

Directions: Read the following three passages, Each passage is followed by several questions or unfinished statements．For each of them there are four choices marked A, B,C and D．Choose the one that fits best according to the information given in the passage.

Humans aren’t the only ones getting a buzz from coffee. Caffeine can improve memory among honeybees and lead to better pollination(授粉). According to a recent study published in the journal Science.

The study was conducted by a team of researchers at Newcastle University in the United Kingdom. They found that the nectar(花蜜) of some flowers, such as those from grapefruit and lemon plants, as well as certain coffee flowers, contains low doses of caffeine. To get bees to feed on these flowers, the team trained the insects to associate food with the smell of the flowers. They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine. After 24 hours, the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants.

Professor Geraldine Wright led the researchers. “Remembering floral traits (花部特征) is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are,” Wright said in a statement.

Improved memory led to the better pollination. That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate. This also suggests that caffeine plays a role in improving the bees’ ability to search for food.

Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals. “The change is similar to that produced by caffeine in neurons (神经元)”associated with learning and memory in the rat brain,” Wright said.

Bee populations have declining since 2007. The dramatic drop in the insects’ numbers has serious effects for ecosystems and the farming industry. Bees are needed in the reproduction of crops and spreading wild flower species. Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers.

1.Which of the following is mentioned in the passage?

A. Caffeine has no effect on the rat brain.

B. Bee population has been increasing.

C. The nectar of lemon plants contains caffeine.

D. Bees dislike nectar from sweetened flowers.

2.After reading the passage, John, who works in the farming industry, will probably feel ________.

A. annoyed B. angry C. nervous D. excited

A. improved memory — caffeine nectar — better pollination

B. caffeine nectar — improved memory — better pollination

C. improved memory — better pollination — caffeine nectar

D. caffeine nectar — better pollination — improved memory

4.We can know from the passage that ________.

A. the rat is a mammal

B. caffeine has nothing to do with memory

C. bees are good at remembering floral traits

D. Geraldine Wright did the research on his own
