Research on different types of bees

文章大意

两位研究者比较澳洲本土蜜蜂与欧洲蜜蜂的研究，重点讨论欧洲蜜蜂面临的瓦螨威胁：瓦螨搭便车进入蜂巢、藏进蜂房、用蜂蜜掩盖气味、吸食幼虫并传播病毒，导致蜂群衰弱甚至灭绝。

题目与答案

1. How the Varroa Mite Attacks

   The mite moves from the bee to 21_____

   ↓
   • the blood
   • a flower
   • the hive
   • the honey
   • a honeycomb cell
   • the queen bee

   答案：a flower

   原文定位：It hops onto a bee. Then, when the bee lands on a flower, the mite gets off and waits for another bee to come along

   同义替换：「The mite moves from the bee to」↔「the mite gets off」

2. The mite travels to 22_____ on a new host

   ↓
   • the blood
   • a flower
   • the hive
   • the honey
   • a honeycomb cell
   • the queen bee

   答案：the hive

   原文定位：And from there, I guess the mite climbs onto another bee;Right. The mite then hitches a ride back to the hive where the bee lives with the rest of the colony

   同义替换：「new host」↔「another bee」，「travels to」↔「hitches a ride back to the hive」

3. The mite uses 23_____ to hide its smell.

   ↓
   • the blood
   • a flower
   • the hive
   • the honey
   • a honeycomb cell
   • the queen bee

   答案：the honey

   原文定位：Well, no. That's the interesting part. It uses the honey to cover its scent, so it won't be detected

   同义替换：「uses」↔「uses」，「hide its smell」↔「cover its scent」，「the honey」↔「the honey」

4. The mite feeds on 24_____ of the bee larva.

   ↓
   • the blood
   • a flower
   • the hive
   • the honey
   • a honeycomb cell
   • the queen bee

   答案：the blood

   原文定位：And presumably, it lives off the blood of the bees;That's right. It feeds on the bee larva that hatches out from the egg

   同义替换：「feeds on」↔「lives off」，「bee larva」↔「bee larva」

5. The mite reproduces and moves on.

   ↓

   The bee is left weakened and with 25_____
   • the blood
   • a flower
   • the hive
   • the honey
   • a honeycomb cell
   • the queen bee

   答案：a virus

   原文定位：Well, it leaves them debilitated, and it also infects them with a virus that spreads amongst the colony

   同义替换：「left weakened」↔「leaves them debilitated」，「a virus」↔「a virus」

6. European Bumblebee
   • could introduce pests
   • needs a warm climate
   • not much is known about it
   • numbers are too few to help farmers
   • spreads weeds
   • too aggressive

   答案：spreads weeds

   原文定位：Okay, then. Let's start with the European bumblebee. There's been a lot of talk recently about bringing them into this country;Yes, but the problem is that the bumblebee has a tendency to carry weeds to nearby farmland

   同义替换：「spreads」↔「carry」，「European Bumblebee」↔「European Bumblebee」

7. Blue Banded Bee
   • could introduce pests
   • needs a warm climate
   • not much is known about it
   • numbers are too few to help farmers
   • spreads weeds
   • too aggressive

   答案：not much is known about it

   原文定位：You know, there's an Australian native bee, the blue banded bee, which is good at pollinating without carrying weeds. It could be useful to farmers. The blue banded bee;I've never heard of that one;That's one of the challenges we face because there hasn't been a lot of research on it as yet

   同义替换：「not much is known about it」↔「hasn't been a lot of research on it as yet」，「Blue Banded Bee」↔「The blue banded bee」

8. Africanised Bee
   • could introduce pests
   • needs a warm climate
   • not much is known about it
   • numbers are too few to help farmers
   • spreads weeds
   • too aggressive

   答案：too aggressive

   原文定位：The Africanized bee is a case in point. It was introduced into South America because it was a good honey producer. But what they didn't realize was that it attacks anything that moves

   同义替换：「too aggressive」↔「attacks anything that moves」，「Africanised Bee」↔「The Africanized bee」

9. Australian Stingless Bee
   • could introduce pests
   • needs a warm climate
   • not much is known about it
   • numbers are too few to help farmers
   • spreads weeds
   • too aggressive

   答案：needs a warm climate

   原文定位：The main drawback with the stingless bees is that they're quite sensitive to temperature. They just won't fly if it gets below eighteen degrees, so they aren't really suited to southern parts of Australia

   同义替换：「needs a warm climate」↔「aren't really suited to southern parts of」，「Australian Stingless Bee」↔「the stingless bees」

10. Canadian Leafcutter Bee
    • could introduce pests
    • needs a warm climate
    • not much is known about it
    • numbers are too few to help farmers
    • spreads weeds
    • too aggressive

    答案：numbers are too few to help farmers

    原文定位：Of course, the only drawback is that we can't bring in very many at a time, so we still don't have enough of them here to really make much difference to our crop yields

    同义替换：「numbers are too few」↔「don't have enough of them」，「to help farmers」↔「make much difference to our crop yields」
