I passed all the other courses that I took at my university, but I could have never passed botany. This was because all botany students had to spend several hours a week in a laboratory looking through a microscope at plant cells, and I could never once see a cell through a microscope. This used to make my professor angry. He would wander around the laboratory pleased with the progress all the students were making in drawing the structure of flower cells, until he came to me. I would just be standing there. “I can’t see anything,”I would say. He would begin patiently enough, explaining how anybody can see through a microscope, but he would always end up angrily, claiming that I could too see through a microscope but just pretended that I couldn’t. “It takes away from the beauty of flowers anyway.”I used to tell him.“We are not concerned with beauty in this course,”he would say.“We are concerned with the structure of flowers.” “Well,” I’d say.“I can’t see anything.” “Try it just once again,” he’d say, and I would put my eye to the microscope and see nothing at all, except now and again something unclear and milky. “You were supposed to see a clear, moving plant cells shaped like clocks.” “I see what looks like a lot of milk.” I would tell him. This, he claimed, was the result of my not having adjusted the microscope properly, so he would readjust it for me, or rather, for himself. And I would look again and see milk.
I failed to pass botany that year, and had to wait a year and try again, or I couldn’t graduate. The next term the same professor was eager to explain cell-structure again to his classes. “Well,”he said to me, happily, “we’re going to see cells this time, aren’t we?” “Yes,sir,” I said. Students to the right of me and to the left of me and in front of me were seeing cells; what’s more, they were . Of course, I didn’t see anything.
So the professor and I tried with every adjustment of the microscope known to man. With only once did I see anything but blackness or the familiar milk, and that time I saw, to my pleasure and amazement, something like stars. These I hurriedly drew. The professor, noting my activity, came to me, a smile on his lips and his eyebrows high in hope. He looked at my cell drawing. “What’s that?”he asked.“That’s what I saw,”I said.“You didn’t, you didn’t, you didn’t!”he screamed, losing control of himself immediately, and he bent over and looked into the microscope. He raised his head suddenly. “That’s your eye!”he shouted.“You’ve adjusted the microscope so that it reflects!You’re drawn your eye!”Why couldn’t the writer see the flower cells through the microscope? .
A.Because he had poor eyesight |
B.Because the microscope didn’t work properly |
C.Because he was not able to adjust the microscope properly |
D.Because he was just playing jokes on his professor by pretending not to have seen it |

A.His professor expected him to have seen the cells and drawn the picture of them |
B.His professor hoped he could perform his task with attention |
C.His professor wished him to learn how to draw pictures |

If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't breathing, you have four minutes before his brain is completely destroyed. Support his neck, move his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils (the two holes at the end of your nose, through which you breathe and smell things) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until professional help arrives.
To bring a child back to life, keep your lips around his mouth and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue-grey colour, and you can feel no pulse(脉搏), then pressing is the last chance of saving his life.
With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib. Check how effective you are by seeing if his colour improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives. If you want to save someone drowning, you __________.
A.have to pull off his clothes first . |
B.should try to get him out of water as quickly as possible. |
C.should first make out who he is. |

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable. People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.A good title for this reading passage is______.
A.Popeye the Sailor | B.The Truth About Spinach |
C.A Mistake with Numbers | D.Folic Acid Makes You Strong |
Why did many people eat spinach after they saw Popeye the Sailor?
A.They thought spinach made them strong. |

D.People liked folic acid. |
A research group told people that spinach______.
A.made Popeye strong |
B.was a green vegetable |

When your toothbrush is at the end of its days, don’t just throw it away, as a survey has revealed many other uses for an old toothbrush.

Some other uses for toothbrushes include cleaning bikes, computer keyboards, toilet seats, fish tanks and finger nails.
The survey also found that the age of the owner can determine what happens to a toothbrush after it is not suitable to be used to brush teeth any more. People over 75 are three times more likely to re-use their toothbrush for a different purpose than those between the ages of 16 and 34 and twice more likely than those between 35 and 44.
Additionally, to reuse their toothbrush for chores (日常琐事) and other uses than their male counterparts. Some women admitted to using their toothbrush to apply hair dye (染料)while some men said they used an old toothbrush to clean their dog’s teeth.
Chief Executive of the British Dental Health Foundation, Dr Nigel Carter, said, “We all should get through around four toothbrushes every year if we are to keep our oral health in great condition. Generally people don’t change their toothbrushes often enough, but there are still plenty of toothbrushes
lying around the house. Our survey has shown that people have realized that a toothbrush is of great value and has a role to play beyond its normal use.”What would be the best title for the passage? (no more than 10 words)
