(Mike is picking up the phone when Alice enters.)

Alice: Are you phoning Linda?

Mike: Yes. But how do you know?

Alice:  61

Mike: What did they say?

Mike: What happened?

Alice:   63  She had to go and take his place for three days.

Mike: That’s too bad.

Alice:  64

Mike: You see, I had arranged for us to have dinner with a friend tonight.

Alice:  65

Mike: Sure, why not?

A. Isn’t she your girlfriend?

B. They said she had left for London.

It’s great fun to explore (探索) new places―it feels like an adventure, even  when you know you’re not the first to have been there. But make sure not to get lost or waste time going round in circles.

● Do the map reading if you’re being driven somewhere. It’ll be easier if you keep turning the map so it follows the direction you’ re traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you’ll have to move to the back seat.

● Get a group of friends together and go exploring. You’ll need a good map, a compass (指南針), a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies (應(yīng)急現(xiàn)金). Tell someone where you’re going before you set out and let them know what time you expect to be back. The test is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

● See if your school or a club organizes orienteering activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B (and B to C, etc. ) in the fastest time, or simply as a spare-time activity. Either way, it’s not only good fun, but a great way to keep fit.

49. Sitting beside the driver, you should ________. 

A. direct the driver when necessary

B. look ahead to see where there’s a turn

C. move to the back seat if feeling uncomfortable

D. keep looking at the map to find a place to go to

50. Why do you need to tell someone your exploration plan before setting out?

A. To get information when in danger.

B. To be saved in case of an accident.

C. To share the fun with him/her in exploration. 

D. To tell him/her what’s going on with the group members.

51. Orienteering activities can ________. 

A. make people work fast         

B. help people stay healthy

C. help people organize other activities    

D. make people get prepared for sports

Rice plants normally grow well in still water. But most will die if they are completely underwater for more than four days. Now, researchers have identified a gene (基因) that helps rice survive longer underwater. They say the discovery will lead to new kinds of rice plants that can survive flooding, and therefore reach their final aim, ensuring more dependable food supplies.

Tests are now being done in Laos, Bangladesh and India. The researchers say experimental rice plants with the gene have survived underwater as long as two weeks. When flooding happens, most kinds of rice plants cannot get enough oxygen, carbon dioxide or sunlight. But the scientists say crop loss depends on several conditions. These include soil conditions and plant age. Others include the amount of time the plant is underwater and the amount of fertilizer (肥料) used on the crop.

On a genetic (遺傳的) map of rice, the scientists became interested in a group of three genes. They experimented with one of them, a gene known as Sub-One-A. They found that when this gene becomes very active, it improves the ability of rice to survive longer when rice is covered by water. They believe it succeeds because it affects the reaction to hormones (荷爾蒙). They control the ability of a flooded plant to survive. Placing the gene into rice plants that are especially good for conditions in India, researchers say the genetically engineered plants not only survived but also produced good crops.

The researchers are now trying to identify all the genes governed by the Sub-One-A gene. Being able to leave water on rice plants for an additional week might also help farmers prevent the growth of weeds. Less weed growth around their crops would mean less need for herbicide (除草劑) chemicals.

41. Crop loss depends on all the following conditions EXCEPT _______.

A. soil conditions and plant age

B. the amount of water the plant stands in

C. the amount of fertilizer used on the crop

D. the amount of time the plant is underwater

42. What is the final aim of this research?

A. To identify the gene that helps rice survive underwater.

B. To increase the ability of rice to fight against floods.

C. To help farmers spend less time removing weeds.

D. To make sure of enough food supplies.

43. What does the underlined word “They” in Paragraph 3 refer to?

A. Genes.                                             B. The experiments.

C. Genetically engineered plants.             D. Hormones.  

44. What would be the best title for the passage?

A. Rice research is going on in Laos and India

B. How to reduce the influence of floods on rice

C. Gene researchers work on flood-resistant rice

D. A great discovery in the agricultural field 

My father was dying of cancer and no one could save his life. All my family could do was    21    Dad at home until his death. I was then a    22    and was taking a required course twice every week.

A week before the   23   ended, Dad’s condition became terminal (晚期的). I knew I    24    to let my professor know that I might be    25   from the classes. I told him the truth in his office and asked if he would allow me to   26  up for the classes later. The professor looked down at his book and then    27    said, “Don’t worry. The course    28    for you today. You’ve been an A student. How would this change in a    29   ?  Go home to your father. That is    30    you need to be.” A few days later, as I    31    my father during his last hours, I knew that the professor’s kindness had    32    the heavy burden from my heart. The kindness also made it    33    for me to give all my    34    to my father during his last days. Until today, I still treasure the memory of being    35    to be at home with my father at the time of his death.

Now, I have been a    36   . Over the years, I have had several occasions to    37    that professor’s example as I worked with my students,    38    tragedy in their own lives.  Yes, I did learn about research methods in his class. However, the    39    of a teacher’s understanding and sympathy    40    the greatest lesson I learnt from him.

A. put              B. gave         C. threw           D. brought
