四、阅读理解
阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
I never really paid much attention to one particular flower until this year. The tulip (郁金香). Yes, it is beautiful. It is one of the first signs of spring. Still, I can’t say that I have attempted to add it to our garden simply because it has such a short lifetime.
Tulips are suitable to be gifts. So, the few we have in and around our house have come from the gifts given to us or the ones I have chosen for my wife like this year. Because the weather warmed very early, I wanted to buy something ＂spring like＂ to begin growing. I chose a small tulip already producing new leaves and gave it to my wife.
In a very short time it began growing. Because it was truly the first visible sign of spring for me, I paid more attention to it and I’m glad I did. Every morning it opened in response to the sun welcoming all that it had to offer. Every evening it closed. This went on without hesitation for days. Then one day I found it spread its flowers fully in the sunlight. I had never seen it in that way before. Out of curiosity I touched the flower and two leaves. I felt terrible. It was then that I realized that the flower had come to the end of its days. That was when I realized how much I had been missing by not paying more attention to the tulip.
Still, the most amazing part was that it really wasn’t over yet. When I would see it as a gone too soon dead flower, it was already planning for a comeback. You see, the remaining leaves begin storing energy for future growth next year.
1. The author wouldn’t add the tulip to their garden before because ____________.
A. it was an expensive plant
B. it needed special care
C. it had a short lifetime
D. it took a lot of space
2. The author paid more attention to the tulips because _____________.
A. they were more beautiful than other flowers
B. they were in flower earlier than other plants
C. the flowers smelt sweeter than others
D. they needed to be watered more times
3. What is the feature of the tulip?
A. It opens in the day and closes at night.
B. It opens at night and closes in the day.
C. It opens both in the day and at night.
D. The time of its being open is long.
4. What does the tulip look like before the end of its life?
A. The flowers appear to be smaller and dead soon.
B. The dead leaves fall onto the floor.
C. The flowers become too dry to be touched.
D. The flowers spread to their fullest.
【答案】

3. A 【解析】细节理解题。根据第三段＂Every morning it opened in response to the sun welcoming all that it had to offer. Every evening it closed.＂可知，郁金香的特征是白天迎着太阳打开花瓣，晚上又将花瓣合上。
4. D 【解析】细节理解题。根据第三段＂Then one day I found it spread its flowers fully in the sunlight... It was then that I realized that the flower had come to the end of its days.＂可知，郁金香在生命即将结束时花朵最为饱满。
B
Brown cows may not actually make chocolate milk, but pink silkworms (蚕) do produce pink silk, a team of scientists has discovered. To see if they could produce predyed silk — silk that comes colored, straight from the source — the team fed ordinary silkworms mulberry (桑树) leaves that had been sprayed with fabric dyes (染色剂). Out of seven tested dyes, only one worked, producing a thread that reminded me of pinkdyed hair.
And yes, the worms themselves take on some color before they produce silk. Their colorful diets did not affect their growth, the team, which included engineers and biologists from the CSIR — National Chemical Laboratory in India, reports in the journal ACS Sustainable Chemistry & Engineering. (The researchers didn’t look too deeply into how the dyes affected the silkworms’ health. After all, silkworms die when people harvest their silk.)
The team made dyeing silk this way because coloring fabric normally uses large amounts of fresh water. The water gets polluted with dangerous chemicals in the process, requiring costly treatment before factories can send it back into waterways. Dyeing silk directly by feeding silkworms would avoid those waterwashing steps. Scientists are just starting to study this idea. However, it remains to be seen if it’s commercially successful. In this experiment, the Indian team tested seven dyes, which are cheap and popular in the industry.
The scientists found different dyes moved through silkworms’ bodies differently. Some never made it into the worms’ silk at all. Others colored the worms and their silk, but the color disappears before the silk is turned into fabric. Only one dye, named ＂direct acid fast red＂, showed up in the final, washed silk threads. By the time it made it there, it was a pleasant, light pink.
5. The text is most probably a(n) ______________.
A. science report B. tourist guide
C. animal experiment D. fashion advertisement
6. Silkworms can produce pink silk because ______________.
A. they are born pink
B. they are dyed pink
C. they grow in pink water
D. they are fed dyed food
7. Where was the experiment carried out?
A. In America. B. In India.
C. In Israel. D. In China.
8. How many dyes have been proved successful in the experiment?
A. One. B. Three.
C. Five. D. Seven.
【答案】
【语篇解读】本文是一篇说明文。你听说过蚕能吐出粉色的丝吗？印度的科学家做了大量的实验，他们通过给蚕喂一些喷过染色剂的桑叶，最终成功地使蚕吐出了粉色的丝。

7. B 【解析】细节理解题。根据第二段第二句中的＂... the team, which included engineers and biologists from the CSIR — National Chemical Laboratory in India ...＂可知，实验是在印度进行的。故选B。
8. A 【解析】细节理解题。根据最后一段倒数第二句＂Only one dye, named ‘direct acid fast red’, showed up in the final, washed silk threads.＂可知，只有一种染料成功了。故选A。

A survey basing on 1,000 students found that 80% of senior students sleep less than nine hours every night. One main reason lies at students’ bad habits. Too much homework is given by school teachers is another main cause. Some students are absent-minded while doing their homework, and some wasting their after-class time. The third cause was that some students have to get up earlier on weekday to get to school that far away from home. Experts think an amount of homework for the students should be cut down.
