Advanced Leader’s Reading 1 Unit 1 The Common Cold
If you’re like most people, you catch a cold at least once a year. It’s the most
________________? In fact, there are around 200 different viruses that cause a cold,
and those 200 viruses are constantly changing. That’s why we can’t find a cure for
the cold or _________________________. It’s not really one disease.
Most of those viruses are in a family called “rhinoviruses,” which comes from the
Greek word “rhino” meaning “nose.” The back of the nose is where the virus attacks.
This is part of___________________________, which includes your throat and
larynx, or voicebox (the respiratory system is what you use for breathing). These are
the places where you feel_______________________, with the most common
symptom being a runny nose. Other symptoms include a sore throat, sneezing,
coughing, ______________, and a general feeling of weakness or laziness. Many of
these symptoms are similar to those of the flu, and it is sometimes difficult to know
How is the cold virus transmitted? ________________, how do you catch or give a
cold? The virus lives in the secretions from your nose and lungs. It must somehow
get into your body, normally through your nose as well as through your eyes, which
______________ the nose through the tear ducts. If someone with a cold coughs or
sneezes and _________________________________, you may catch the cold. The
virus can also survive for a few hours outside of the body, so a person can
contaminate objects with the virus (by sneezing on them or wiping their nose with
their hands and then touching things, for example). If other people touch those
objects then wipe their eyes or noses, they may become infected.
Understanding how colds are passed from person to person can ____________
the spread of the viruses. The most important thing, as with any virus, is good hand-
_________ that everyone else touches such as doorknobs, public telephones, and bus handles. Don’t rub your eyes and nose. And if you have a cold, be sure to cover your mouth when you sneeze or cough so that you don’t ___________________.
Advanced Leader’s Reading 1 Unit 2. Fire
It is difficult to know exactly what happened a long time ago, but anthropologists are fairly
certain that about 1 million years ago people in Africa first learned to use fire. They
______________________ naturally, from lightning or the sparks that rocks made when they
_________________. They were probably ________________and grass fires, but they
learned that fire was not just dangerous but also useful. In fact, people started using fire
brought___________________. Firstly, cooked food, especially meat, was a lot safer to eat
than raw food. Secondly, cooked food is a lot ____________________________. This
meant that people’s bodies didn’t have to spend so much energy. Many experts believe that
this actually allowed people’s brains to grow bigger.
For early humans, fire was not easy to manage. They had to take care of it, or else it
would go out. This meant that people couldn’t constantly wander as nomads but _________
_______________________. Taking care of fire is part of the reason people started forming
groups or tribes. Eventually they learned how to make fire more easily, with special
________ ___________ and by rubbing sticks together, but they still had to cooperate more.
Besides helping people cook food, fire kept them warm. About 12,000 years ago people
started moving indoors, living in caves. With warm shelter, they could survive in much colder
climates. People spread to places where they ___________________________. The fire
protected them not only from the cold but also from wild animals, which were afraid of fire.
About 8,000 years ago people were beginning to live in houses and control fire in ovens.
They ___________________ for cooking and soon discovered that they were useful for
making pottery. They designed special ovens called kilns and made extremely hot fires for
The next major step in the use of fire occurred about 5,000 years ago, when people in
West Africa started using very hot charcoal fires to melt copper and tin in order to make
bronze. They then used this metal to create all sorts of tools and art. ___________ later
people in western Asia _______________________________________, a much stronger
Now, can you imagine the world without __________, cooked food, and heat for warmth?
Impossible. It should be clear from these examples that learning to control fire was ________

__________________ that humans have done.
Unit 3. Homeschooling
Some people decide not to send their children to school. Instead, they provide education
at home. We call this homeschooling. Let’s have a look ________________ reasons why
people choose to do this. Then we can ____________________________ homeschooling.
Surveys of people who choose to home-school their children reveal a huge number of
reasons. In many cases, parents have no choice other than homeschooling. This occurs
when they ___________________ with no school nearby. In other cases, children have
special __________________________ properly by the school system. This could mean
children with serious mental or physical handicaps or with psychological or social difficulties.
Many schools do not have special programs for such children. Even when they do, a lot of
parents find that they are not perfectly suited to their children, or that the teachers do not
Other parents may have moral and social reasons as well. Schools can be very difficult
places for children. Many parents _________________ safety, bullying, drugs,
___________________, and peer pressure. Protecting children from negative influences is
important to all parents, but to some it is so important that they _________________. They
feel they can not only keep their children safe, but also give them a better sense of right and
The most common reason for homeschooling, however, is that parents believe that
schools don’t do a good job of education. Perhaps they disagree with the
___________________ (often for religious reasons), or they think the methods used are not
effective. It is quite common, in fact, for homeschooling parents to say that they feel they can
help their children _______________________ than the schools can.
So, do parents who homeschool really give their children advantages? Or do the children
____________ something very important? Well, it is true that children with special needs
may be ______________________ with their parents who understand them. In such cases,
parents usually find other ways to socialize their children outside of home. Some studies
have also shown that children are ________________ drugs and experience physical abuse
when they are homeschooled. In addition, homeschooled children do actually score higher
____________________, including the SAT and ACT, which are used to enter university.
But if homeschooling is so great, why doesn’t everyone do it? Well, there are very good
Advanced Leader’s Reading 1 Unit 4. Marriage
Although customs, rituals, and traditions may vary, virtually every culture has
some idea of marriage between a man and a woman. Where does this come from?
When did people first ___________________________? And why did they do this?
The first evidence of a wedding ceremony in history is from about 4,350 years ago.
That doesn’t mean that _____________________ that year; that’s just the first
evidence of a ceremony, and it should give you a good sense that marriage is a very
old custom. Marriage at that time, however, was not really about ________________
today. If you think marriage is about love and romance, then you might not want to
If it wasn’t about love and romance, what ______________? Well, it had several
different purposes, both social and economic. For one thing, marriage ____________
_______ bloodlines. It is normally very clear who a child’s mother is, but a very long
time ago, when people lived in large loose groups, it was sometimes unclear who a child’s father was. If a man and a woman formed a lasting bond, then the man _____
__________________ whose children were his.
Why would it suddenly be important who a child’s father was if it wasn’t before?
For one thing, it mattered because people had property. When people stopped their
hunting and gathering way of life and started farming, they started owning land. They
therefore _________________ that land on to their children.
A long time ago, women didn’t have very much equality in marriage. ___________
_______________ a man’s property. A father would “give” his daughter to another
family or another man. In many cases, he would receive a lot of money for this.
Having women to marry was important for continuing a family. They _____________
________, and men can’t do this alone! In fact, if a married woman was not able to
have babies, she could sometimes be given back to her father.
There were other important issues as well. Marriage was a good way to ________
_______ between families, groups of families, or tribes. If a man gave his daughter as a wife to another man’s son, the two families would have a bond. They would help
each other ______________ and not attack each other. In fact, this is still very
important in many places. In a general sense, in most societies we can still see a
tendency for families of similar backgrounds to have marriages together.
Advanced Leader’s Reading 1 Unit 5. Polar Animals
If you go as far as you can north or south, you come to _____________________.
If you do go, make sure you pack a lot of warm clothes and food. These areas are
not _______________________. They are very cold and very icy. You will find very
little plant life and a lot of dangers. Despite the difficulties of these environments,
however, you will discover some animal life. Exactly which animals you find, however,
There are important differences between the north and south poles, or, in other
words, _________________________. Firstly, the northern Arctic is actually a frozen
ocean ________________ land. Antarctica, in the south, is an actual landmass
surrounded by ocean. Secondly, the South Pole is much colder than the North Pole.
The average winter temperature in Antarctica is _________________, while in the
Arctic it is -34. These facts may affect which animals can live in the regions.
The northern region has many land animals. ________________________ the
polar bear, a huge white bear that likes to hunt for seals from the edges of ice floes.
The polar bear has thick fat and fur so that it can _______________ and is the
largest meat-eating land animal. Another Arctic animal is the caribou, or reindeer.
Caribou are large grazing animals _________________. They can migrate up to
5,000 km per year looking for bits of plant life to eat. Smaller Arctic animals include
the arctic fox and the arctic hare, ______________ change the color of their coats
depending on the season (white in winter, brown/grey in summer). The arctic fox
_____________________ to catch smaller animals under the snow, while the arctic
hare uses its sense of smell to find bits of plants beneath the snow.
In Antarctica, there are almost no animals that live just on land. Instead, most of
the life lives in the sea, ____________________________. The most famous animal here is the penguin. Most people recognize the Emperor penguin but don’t realize
there are many other types of penguin _________ the rockhopper penguin, the
chinstrap penguin, and the gentoo penguin. There are also fur seals, cousins to the
seals near the North Pole, and blue whales, the largest animals on planet Earth.
Another large sea animal is the colossal squid, which can ____________________.
Advanced Leader’s Reading 1 Unit 6. Puberty
Puberty is a period of life in which boys and girls _________________. Their bodies and
emotions ______________ as they move from being children to adults. It is a difficult time,
Puberty happens at different ages for boys and girls. Girls usually begin puberty around
age 10, while boys normally begin around age 12. Girls usually finish most of their changes
______________ 16 or 17, while boys often continue changing until age 18 or 19. These
ages are just averages. There is actually _______________ from person to person. A girl
may begin puberty as early as age 8, and a boy may not begin until age 14.
The key to puberty is hormones. Hormones are natural chemicals in the body that affect
growth and _________________________. There are some hormones that both men and
women produce equally, but certain hormones ___________________ only one of the sexes.
In puberty, these sex hormones are suddenly produced in larger amounts, which _________
the physical changes that we can see. The main male hormone is called testosterone, while
the main female hormones are estrogen and progesterone.
Some of the changes that come with puberty are experienced by both boys and girls. One
of these is body odor, which can be ________________. Another is acne on the face, which
can be very difficult to deal with, and pubic hair. Both boys and girls will also become quite
clumsy and awkward, as they ______________________ their growing bodies. Both will also
become very sensitive and moody, which can be a real headache for parents and teachers.
When boys enter puberty, they will notice a change in their sexual organs, which is where
the hormone testosterone is produced. This is part of becoming sexually mature. Their
skeletons change so that they have broad shoulders and jaws, and they get more muscle.
____________ will change, sometimes very quickly, becoming much deeper and fuller.
Finally, boys will begin to grow hair on their faces (shaving for the first time is a major
milestone) and their legs. Girls also become sexually mature. This process includes the
development of breasts (the first bra is a big step) and the widening of the hips. Girls will also
start getting their periods, although in the beginning it may not be very regular.
_________________________ like boys, girls will see an increase in the amount of body fat.
Just remember: puberty is natural. It happens to everyone. If you ___________________,
