    : Technology and Medicine

    Read the passage below and answer the questions that follow:

    A large number of digital innovations are revolutionizing healthcare and 

    technology in medicine is here to stay. Numerous innovations and 

    new solutions are already on the market and they have all improved 

    healthcare drastically. Today, multiple medical issues such as congestive 

    heart failure, diabetes, medication noncompliance, even stressful 

    isolation, are researched and solved with remarkable new technologies. 

    The following are some areas researchers are targeting:The first area 

    targeted by researchers is heart failure. One of the most common and 

    costly diagnoses is that of heart failure, with a mortality rate closer 

    to cancer. It includes three types of sensors – wristband, necklace and 

    watch – which are used for testing. This type of diagnosis gives both 

    patients and doctors continuous information on how a compromised 

    heart is functioning.

    The second area targeted by researchers is 3D printing. These days, 

    medical researchers are considering the potential of 3D printing in 

    medicine. For example, Kaiser Permanente’s Los Angeles Medical Center 

    is perfecting the use of 3D printers to replicate multidimensional models 

    of problematic areas inside patients. Surgeons can handle the models 

    and simulate a variety of possible operation replicas before performing 

    the actual surgery. Alternatively, 3D printing can be used in reproducing 

    bones or other organs in the human body.

    The second area targeted by researchers is the area of mobile applications. 

    Today, mobile applications are available for everything. In the healthcare 

    sector, this is especially true. Doctors and patients are discovering new 

    ways to use technology to monitor personal health. Nowadays, tracking 

    daily sleep patterns, counting calories, researching treatment options, 

    and even monitoring heart rate is possible.

    Thirdly, remote monitoring technology is one of the most useful 

    and practical innovations in recent years. The systems can be used by 

    patients in the comfort of their homes to reduce the time and financial 

    cost of recurring visits to the doctor. By using a small device designed to 

    measure a particular health issue, doctors can analyse a patient’s data 

    remotely without the need for them to come down to the hospital.

    This must be the reason why the Government of Rwanda recognized that 

    there is a need to strengthen science, technology and research and is 

    engaged in many National and Regional initiatives to help build this 

    capacity.

    • Text 2: Body systems

    Read the passage below and answer the questions that follow:

    Our bodies consist of a number of biological systems that carry out specific 

    functions necessary for everyday life.

    The job of the circulatory system is to move blood, nutrients, oxygen, 

    carbon dioxide, and hormones, around the body. It consists of the heart, 

    blood, blood vessels, arteries and veins.

    The digestive system consists of a series of connected organs that 

    together, allow the body to break down and absorb food, and remove 

    waste. It includes the mouth, oesophagus, stomach, small intestine, 

    large intestine, rectum, and anus. The liver and pancreas also play a role 

    in the digestive system because they produce digestive juices.

    The endocrine system consists of eight major glands that secrete 

    hormones into the blood. These hormones, in turn, travel to different 

    tissues and regulate various bodily functions, such as metabolism, 

    growth and sexual function

    The immune system is the body›s defence against bacteria, viruses

    and other pathogens that may be harmful. It includes lymph nodes, 

    the spleen, bone marrow, lymphocytes (including B-cells and T-cells), the 

    thymus and leukocytes, which are white blood cells.

    The lymphatic system includes lymph nodes, lymph ducts and lymph 

    vessels, and also plays a role in the body›s defences. Its main job is to 

    make and move lymph, a clear fluid that contains white blood cells, which 

    help the body fight infection. The lymphatic system also removes excess 

    lymph fluid from bodily tissues, and returns it to the blood.

    The nervous system controls both voluntary action (like conscious 

    movement) and involuntary actions (like breathing), and sends signals 

    to different parts of the body. The central nervous system includes the 

    brain and spinal cord. The peripheral nervous system consists of nerves 

    that connect every other part of the body to the central nervous system.

    The body’s muscular system consists of about 650 muscles that aid in 

    movement, blood flow and other bodily functions. There are three types 

    of muscle: skeletal muscle which is connected to bone and helps with 

    voluntary movement, smooth muscle which is found inside organs and 

    helps to move substances through organs, and cardiac muscle which is 

    found in the heart and helps pump blood

    The reproductive system allows humans to reproduce. The male 

    reproductive system includes the penis and the testes which produce 

    sperm. The female reproductive system consists of the vagina, the uterus 

    and the ovaries which produce eggs. During conception, a sperm cell 

    fuses with an egg cell, which creates a fertilized egg that implants and 

    grows in the uterus.

    Our bodies are supported by the skeletal system, which consists of 

    206 bones that are connected by tendons, ligaments and cartilage. The 

    skeleton not only helps us move, but it’s also involved in the production 

    of blood cells and the storage of calcium. The teeth are also part of the 

    skeletal system, but they aren’t considered bones.

    The respiratory system allows us to take in vital oxygen and expel 

    carbon dioxide in a process we call breathing. It consists mainly of the 

    trachea, the diaphragm and the lungs.

    Theurinary system helps eliminate a waste product called urea from the 

    body, which is produced when certain foods are broken down. The whole 

    system includes two kidneys, two ureters, the bladder, two sphincter 

    muscles and the urethra. Urine produced by the kidneys travels down 

    the urethras to the bladder, and exits the body through the urethra

    The skin, or integumentary system, is the body’s largest organ. 

    It protects us from the outside world, and is our first defence against 

    bacteria, viruses and other pathogens. Our skin also helps regulate body 

    temperature and eliminate waste through perspiration. In addition to 

    skin, the integumentary system includes hair and nails

    • Text1: The positive and negative impacts of ICT

    Read the passage below and answer the questions that follow:

    As it is known from time immemorial that everything in life is like the 

    two sides of a coin, there is always a positive and negative side of every 

    phenomenon. But whether the effect is positive or negative the effects 

    of Information Communication Technology (ICT) is far reaching and 

    cannot be overemphasized. The Effects of ICT lens looks at how our 

    lives have been changed, for better and for worse, by the impact of ICT. 

    It includes both positive effects and negative effects.

    One of the positive effects of ICT is access to information. Possibly 

    the greatest effect of ICT on individuals is the huge increase in access 

    to information and services that has accompanied the growth of the 

    Internet. Some of the positive aspects of this increased access are better, 

    and often cheaper communications, such as phone calls and Instant 

    messaging. In addition, the use of ICT to access information has brought 

    new opportunities for leisure and entertainment.

    Another positive effect of ICT is easy access to education. With ICT there 

    are new ways of learning, such as interactive multi-media and virtual 

    reality. ICT has also created new job opportunities, such as flexible and 

    mobile working, virtual offices and jobs in the communication industry 

    among others.

    ICT can be used for processes that had previously been out of the reach 

    of most individuals, such as photography, where digital cameras, photoediting software and high-quality printers have enabled people to produce 

    results that would previously require a photographic studio.

    ICT can be used to help people overcome disabilities. For example, screen 

    magnification or screen reading software enables partially sighted or 

    blind people to work with ordinary text rather than Braille.

    As far as negative effects are concerned, ICT has caused Job loss, reduced 

    personal interaction and reduced physical activity. 

    As for Job loss, one of the largest negative effects of ICT can be the loss 

    of a person’s job. This has both economic consequences, loss of income, 

    and social consequences, loss of status and self-esteem. Job losses 

    may occur for several reasons, including the replacement of manual 

    operations by automation. This can happen when, for example, robots 

    replace people on an assembly line. People can also lose jobs due to Job 

    export. This is when Data processing work is sent to other countries 

    where operating costs are lower. Multiple workers can also be replaced 

    by a smaller number of people who are able to do the same amount of 

    work using machines.

    Personal interaction and physical activity have also been negatively 

    affected by ICT. Being able to work from home is usually regarded as 

    being a positive effect of using ICT, but there can be negative aspects 

    as well. Most people need some form of social interaction and physical 

    exercise.

    9.3. Language structure: Word formation

    Introduction:

    In linguistics (particularly morphology and lexicology), word 

    formation refers to the ways in which new words are made on the basis of 

    other words or morphemes. This is also called derivational morphology. 

    Most English vocabulary arises by making new lexemes out of old ones. 

    This can be done either by adding an affix to previously existing forms, 

    altering their word class, or combining them to produce compounds. 

    Below are some types of word formation processes.

    A. Derivation

    Derivation is the creation of words by modification of a root without the 

    addition of other roots. Often the effect is a change in part of speech.

    Examples

    • Empty-emptiness (adjective was changed into a noun)

    B. Affixation

    (This is like a subtype of derivation)

    Affixation is the process of adding a morpheme or affix to a word to 

    create either a different form of that word or a new word with a different 

    meaning; affixation is the most common way of making new words in 

    English. An affix is a word element of English grammar used to alter 

    the meaning or form of a word and comes in the form of either a prefix or 

    a suffix. There two primary types of affixation that are prefixation (the 

    addition of a prefix) and suffixation (the addition of a suffix). 

    C. Prefixation

    Prefixation is a morphological process whereby a bound morpheme is 

    attached to the front of a root or stem. The kind of affix involved in this 

    process is called a prefix. Prefixes include examples like “un-,” “self-,” 

    and “re-,”

    Example:

    The prefix un- attaches to the front of the stem selfish to form the 

    word unselfish.

    Other examples include

    D. Suffixation

    Suffixation is a morphological process whereby a bound morpheme is 

    attached to the end of a stem. The kind of affix involved in this process is 

    called a suffix. Suffixes come in the form of ending elements like “-hood,” 

    “-ing,” “-ness,”, “-ed…”

    • Communicate-communicator

    Think of the 26 common suffixes in the table as clues to the meaning 

    of words. Keep in mind, though, that the meaning of words is best 

    determined by studying the contexts in which they are used as well as 

    the parts of the words themselves.

    E. Noun Suffixes

    d

    F. Verbs suffixes

    2

    G. Adjective Suffixes
