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.

このレッスンについて
YouTubeで英語学習を楽しみながら、蜜蜂についての面白い事実を学び、英語のスピーキングとリスニング力を向上させましょう！このビデオでは、蜜蜂の体の構造、種類、社会生活などについて説明されています。ゆっくりとしたスピードで分かりやすい表現が使われているので、shadow speech（シャドーイング）の練習に最適です。蜜蜂の知識を増やしながら、自然な英語のリズムと発音を身につけましょう。
重要な語彙とフレーズ
- pollinate（受粉する）：蜜蜂が植物に花粉を運ぶこと。"Bees pollinate thousands of plants."（蜜蜂は何千もの植物に受粉します。）
- compound eyes（複眼）：昆虫の大きな目で、たくさんの小さな目が集まってできています。"Bees have two compound eyes."（蜜蜂には2つの複眼があります。）
- proboscis（口吻）：蜜蜂が蜜を吸うための長い器官。"The proboscis is used to drink nectar."（口吻は蜜を飲むのに使われます。）
- solitary（単独の）：一匹で生活すること。"Some bees are solitary."（一部の蜜蜂は単独で生活します。）
- colony（コロニー）：蜜蜂が集まって生活する集団。"Honeybees live in a colony."（ミツバチはコロニーで生活します。）
練習のコツ
英語の発音を良くするためには、shadow speechを徹底的に練習しましょう。このビデオのスピードは中程度なので、最初は1文ずつ止めながら真似してみてください。特に「180 to 250 times per second」（1秒間に180から250回）のような数字の読み方や、「as busy as a bee」（蜜蜂のように忙しい）のような慣用句のイントネーションに注目しましょう。何度も繰り返して、自分の声がビデオの声と重なるようになるまで練習します。これで英語スピーキング練習が楽しく効果的になり、自然な発音が身につきます！

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
