Part III Reading Comprehension (40 minutes)

　　Section A

　　Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.

　　Questions 36 to 45 are based on the following passage.

　　Global warming is a trend toward warmer conditions around the world. Part of the warming is natural; we have experienced a 20,000 -year -long warming as the last ice age ended and the ice 36 away. However, we have already reached temperatures that are in 37 with other minimum-ice periods, so continued warming is likely not natural. We are 38 to a predicted worldwide increase in temperatures 39 between 1℃ and 6℃ over the next 100 years. The warming will be more 40 in some areas, less in others, and some places may even cool off. Likewise, the 41 of this warming will be very different depending on where you are—coastal areas must worry about rising sea levels, while Siberia and northern Canada may become more habitable (宜居的) and 42 for humans than these areas are now.

　　The fact remains, however, that it will likely get warmer, on 43 , everywhere. Scientists are in general agreement that the warmer conditions we have been experiencing are at least in part the result of a human-induced global warming trend. Some scientists 44 that the changes we are seeing fall within the range of random (无规律的) variation—some years are cold, others warm, and we have just had an unremarkable string of warm years 45 —but that is becoming an increasingly rare interpretation in the face of continued and increasing warm conditions.
