In today's video we are going to learn some fun facts about bees.
3
Bees are fascinating flying insects that play a crucial role in maintaining a healthy ecosystem in our world.
4
They are the reason why we are able to enjoy a wide range of resources, particularly food.
5
In fact, bees contribute to around one third of the food that we eat.
6
This is because they incidentally pollinate the thousands of plants they visit each day.
7
We will revisit pollination a little bit later.
8
Let's now first learn more interesting facts about bees themselves.
9
A bee's body is made up of three parts: the head, the thorax and the abdomen.
10
A bee's eyes are located on its head.
11
Bees have two large compound eyes on the sides of their head
12
and they have three simple eyes located at the top of their head.
13
Yes, you counted right.
14
Bees have five eyes in total.
15
The compound eyes help bees to see shapes, whereas the three simple eyes help it to see light.
16
These are used for smelling and feeling.
17
Bees also have mandibles which are used for grabbing food and biting.
18
And lastly is the proboscis which is used to drink water, nectar and honey.
19
The thorax is where you will see the wings and legs of a bee.
20
Bees have six legs and four wings.
21
They have a pair of wings on each side of their body.
22
Their incredible wings allow them to flap between 180 to 250 times per second.
23
As for the legs of a bee, the front legs are especially designed to clean the antennas.
24
The back legs are used to collect pollen in a pollen basket, which is located on a bee's hind legs.
25
Each of the six legs have claws on the ends that assist a bee with gripping and landing on different surfaces.
26
The largest part of a bee's body is the abdomen, and it's probably the most well -known body part as it's where the stinger is located at the very end.
27
Stinging is usually a bee's last resort for self -defense, as sadly, once it decides to use its stinger, it will typically result in the death of a bee.
28
Bees have existed for around 30 million years and although they are commonly known as little insects with black and yellow stripes,
29
they actually come in different colours and some species even have spots.
30
Did you know that there are over 20 ,000 species of bees in the world?
31
They range in size from just 2mm to 4mm in length.
32
Not all bees are social.
33
There are many who live a solitary life, meaning they live alone.
34
Even though they live alone, they often nest close to one another.
35
Unlike social bees, solitary ones do not have a queen and they do not produce any honey.
36
Some solitary species include mason bees, carpenter bees and the hairy -footed flower bees.
37
Bees that live together in hives or colonies are social bees.
38
They include some popular species like the honeybees and bumblebees.
39
Within a beehive there are three main roles that a bee would have which include queens, drones and worker bees.
40
The queen bee is essential because without her there would be no hive.
41
Once selected and matured her role is to mate, reproduce and spend the rest of her life in the hive laying eggs.
42
up to 2000 eggs per day and she is also the one who lives the longest in the colony, surviving up to 5 years.
43
Unlike worker bees, a queen bee can sting multiple times and still survive.
44
Now let's move on to drone and worker bees.
45
It is easier to tell the difference between drone and worker bees up close.
46
Drones are male bees and are typically wider in size
47
and have rounder abdomens and much larger eyes in comparison to worker bees.
48
They do not have stingers and they do not collect pollen.
49
Their primary role is to mate with the queen so that she can produce eggs.
50
Worker bees have the busiest role in the colony, so the saying "as busy as a bee" is referring to
51
worker bees as they work from the time the sun rises right up until sunset.
52
Younger working bees have the job of taking care of bee larva, feeding the queen, cleaning the hive and processing and storing nectar as well as making honey.
53
Older worker bees have a hugely important job to go foraging to bring back water, nectar and pollen for the whole colony.
54
Because they have to go foraging away from the hive, older worker bees have the riskiest and most tiring job of all,
55
as they are put in the face of danger from predators every time they leave the hive.
56
Regardless of the dangers they face, worker bees carry out their duties to ensure the survival and growth of the colony.
57
While carrying out their jobs, bees play a vital role in the process of pollination.
58
Pollination is when the male part of the flower is transferred to the female part so that fertilization can occur.
59
And this is how bees help to fertilize flowers.
60
While bees are foraging through the flowers that they visit, they rummage through the male part of the flowers called the stamen.
61
This is where pollen is produced.
62
As the bees explore the flower to collect pollen, the pollen gets stuck on their furry bodies.
63
And as the bees continue to move around, they incidentally place pollen in the female parts of the flowers called the stigma.
64
When this happens, the flower is able to produce in the growth of new flowers.
65
It is believed that bees visit thousands of flowers in just one day, so you can imagine just how much pollen they are able to collect.
66
The more flowers they visit, the bigger the pollen basket on their hind legs become.
67
Once they have collected all the pollen they can carry, worker bees bring it back to the hives so that it can be fed to the young.
68
Even though bees play a crucial role in pollinating our crops, they are not the only pollinators in the world.
69
Other pollinators include butterflies, birds, beetles and even bats.
70
Bees have quite a short lifespan.
71
Depending on the species, bees can live between 17 to 60 days.
72
And as you can see, they manage to make a huge impact on our environment in the short amount of time that they survive.
73
Unfortunately, the population of bees are on the decline.
74
There are several factors for this, including disease, loss of habitat and the use of dangerous chemicals that are fatal to bees.
75
So the next time you see a bee, remember to leave it alone because it is doing an important job, not only for itself or its colony, but also for us humans too.

你能学到什么
通过这段视频，你可以锻炼英语口语练习中的两项关键技能：一是如何清晰描述事物（如蜜蜂的身体结构和习性），二是学会用自然的节奏讲述科普知识。同时，视频中的长句结构也能帮助你提升连贯表达的能力，为影子跟读（shadow speech）打下基础。
注意这些发音现象
视频中存在不少连读和弱读现象，比如“around one third”中“around”和“one”的连读，以及“they incidentally pollinate”里“incidentally”的弱读。此外，“20,000 species”中的“20,000”发音时会简化为“twenty thousand”，而非逐个读出数字。这些细节都是提高英语发音的关键，需要在影子跟读时特别留意。
像母语者一样表达
模仿视频中的节奏和重音是英语影子跟读的核心。比如，在说“Bees are fascinating flying insects”时，重音应放在“fascinating”和“insects”上，同时加快“flying”的语速，形成自然的流动感。讲述“queen bee lays up to 2000 eggs per day”时，要强调“2000”和“per day”，突出关键信息。建议使用shadowing site反复练习，感受母语者的语调和停顿，逐步提升口语的流畅度。
视频中的语法
说话人最常用的结构，并附上视频中的原话：
| 结构 | 视频中的用法 |
|---|---|
| 被动语态 be + 过去分词 — 强调发生了什么，而不是谁做的 | is made · are located · is located |
| 定语从句 who / which + 从句 — 补充说明人或事物 | mandibles which are · proboscis which is · basket, which is |
| 现在完成时 have/has + 过去分词 — 过去发生但与现在仍有关联的事 | have existed · have collected |
| 最高级 the -est / the most … — 一组中最高或最低的 | The largest · the longest · the busiest |
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
