• UNIT 8 : THE PHYSICAL ENVIRONMENT



    A. Listening and speaking

    Introduction
    Practise reading the conversation below.
    Gatete, Umutoni and Hirwa are studying a physical geography map of Rwanda. Mubyeyi joins them.

    MUBYEYI:   (looking a bit confused)What are you looking at?
    GATETE:     We are identifying the physical features in our country. I can see a plate
                         in the south.                                                           
    UMUTONI:  A plate? Where is it on this map?
    HIRWA:       He means
                        plateau not
                        plate.
    MUBYEYI:   (laughing) Let me see if I can locate a plate too.
    GATETE:     That is not nice, Mubyeyi.
    MUBYEYI:   I am sorry, I
                         sounded rude.
                         I was only joking.
    UMUTONI:   Hey look! Here .
                         .. the Virunga
                         Mountain Range.
    HIRWA:        Yes, it runs north of Lake
                          Kivu.Lake Kivu
                          is also a physical
                          feature you know!



    MUBYEYI: Hirwa is right. Look, the range includes Mount Karisimbi.
    GATETE:   That is the highest point in our country!
    UMUTONI: Hey look! Here ... the Virunga Mountain Range.
    HIRWA:      In the north there are mountains and in the south ...
    MUBYEYI:  ... a plateau! There is some lower land here ... along the eastern shore of Lake
                        Kivu and the Ruzizi River. This is in the west, right?
    GATETE: Yes, the altitude is lower towards the Tanzanian border.
    MUBYEYI:  Did I tell you we visited Akagera Park last holidays? It has a savannah landscape
                       full of beautiful wild animals. We went through its open grassland, acacia
                       woods, marshes and swamps.
    UMUTONI: Our country is beautiful. Did you know that the Nyungwe Forest ... there it is
                      ... in the southwest − it is the largest mountain rain forest in Africa?
    HIRWA: That is amazing! Our country is made up of rolling grassy hills and valleys! We
                  are the land of a thousand hills!

         c) Rwanda can earn foreign exchange from tourists visiting Virunga Mountains.

    B. Reading and comprehension

    Read the following passage and answer the questions that follow.
    Paula is taking us on a ‘gorilla trip’ in Volcanoes National Park. We were apprehensive
    about sending money for this trip. We haven’t known Paula for long and her tour company
    is not in our travel book. We had only come to know about her through a friend. When we
    finally met and interacted with her, we are ashamed we ever doubted her. She is simply
    amazing.
        “Is this the best time to visit Rwanda?” I had asked as we planned the trip.
        “The ‘best time’ depends on an individual.”
        “Indeed ... what is the weather like?”
        “Here is a rough guide                                                                               
    to the climate in Rwanda.
    However, my knowledge is
    from my experience, not the
    meteorological department.
    Besides, Africa’s weather
    patterns are becoming
    increasingly unpredictable.”
       “It’s the same everywhere,
    Paula ...”
       “Exactly ... Rwanda’s relatively high altitude
    provides it with a pleasant
    tropical highland climate.
    Temperatures vary between
    locations depending on altitude. However, there is very little variation for, say, a month in
    the same place. For instance, Kigali has an average daily temperature of about 21°C. Some
    places are warm at 21°C; others are warmer at 25°C.”
           “Okay ...”
           “Rwanda’s long rainy season lasts from March to May. The longer dry season lasts from
    June to mid September. The driest and hottest month is July.”
            “What of October to December?”
            “We experience a shorter rainy season then. This is followed by a short dry season from
    December to February.”
             From the airport, we went to see the genocide memorial as it was only 10 o’clock. Paula
    then booked us in at Sainte Anne Hotel, Musanze. We left for Hotel Muhabura for a meal
    as she strongly recommended.
             Later, we’ll head south to tour Nyungwe Forest. Finally, we’ll travel west to sunbathe on
    the beaches of Lake Kivu.

    1. Using a dictionary, find out the meanings of the following words:
        a) apprehensive
        b) climate
        c) meteorological department
        d) weather patterns
        e) altitude
        f) temperature
        g) rainy season
    2. Why were the narrator and the other tourists afraid of sending money to Paula?
        A. She was not in their tour book.
        B. She was in a different country.
        C. They hadn’t known her for long.
        D. They hadn’t known her for long and they didn’t have her tour company in their travel book.

        B. ‘Best’ depends on individuals.
        C. She wasn’t happy with the question.
        D. It was rainy and windy.
    4. The average temperature in Kigali is ...............
    5. Rwanda experiences the most rain in the months of ............... and the least in the
         months of ................
    6. Which period will have high temperatures? December to May or June to November?
        Give reasons for your answer.
    7. Why do tourists visit Rwanda?
    8. Give words that show the visitors enjoyed their visit.
    9. Give this passage a suitable title.

    C. Language use

          
     
              The passive voice verb phrase is made up of auxiliary verbs such as am, are, was, were,
    and a main verb.
      


    Rewrite the following sentences in the passive voice.
    1. People generate power from methane in Lake Kivu.
    2. Tourists see gorillas in the Volcanoes National Park.
    3. Rwanda receives long rains between March and May.
    4. Rwandans clean the environment every first Saturday of the month.
    5. People call Rwanda the land of a thousand hills.
    6. Rwanda exports agricultural products to Europe.
    7. Rwanda imports machinery from China.
    8. People use irrigation in about 94 square kilometres of land.
    9. Farmers practice terrace farming.
    10. Farmers cut down trees for agriculture.

    Passive voice with ‘can’
    Passive voice can be used with modal verbs. For example: Trees can be found in Nyamagabe
    Forest.
    Can is a modal verb. Other modal verbs are: could, may, might, must, should, will, would.
    Change the following sentences into either passive or active sentence.Example:
    Electricity can be generated from methane (by people).
    People can generate electricity from methane.
    1. People can see gorillas in the Volcanoes National Park.
    2. People can grow cassava and potatoes in many districts of Rwanda.
    3. Rain water can be tapped and stored for use.
    4. A number of minerals, for example, tin ore and gold, can be mined in Rwanda.
    5. The soils in Rwanda can allow the growth of coffee and tea.
    6. Lake Kivu can be used for transport.
    7. River Akagera can be used for fishing.
    8. Students can write on the chalk board with a teacher’s permission.
    9. School books can be borrowed from the library.
    10. Both boys and girls can play football.

    Passive voice with modal verbs and comparatives
    We can write sentences in passive voice that include modal verbs and
    comparatives. A comparative is used to compare two things using ‘more ... than’. For example:

    1. More electricity can be generated at Ntaruka Power Station than at Mukungwa II
        Power Station.
    2. Western Rwanda can be more ideal for growing coffee than eastern.
    3. Rain received in Kigali might be more than that received in Nyamata.

    Combine the following pairs of sentences using ‘more ... than’. Use the passive voice
    and the modal auxiliary ‘can’.
    1. Rwanda produces flowers. Rwanda can produce three times the flowers it produces if
        she uses many green houses.
    2. Rwanda gets a lot of rain in March and April. She gets less rain in November and
        December.
    3. A lot of power is produced using methane. More power is produced by hydro power
        stations.
    4. Rwanda produces coffee. Uganda produces more coffee.
    5. The environment is cleaned every day. More cleaning is done on the first Saturday of the
         month.
    6. The eastern region is visited by tourists. More tourists visit the western region.
    7. Trees are cut in the Savannah region. More trees are cut in the rain forest.
    8. Eleven people can play football. Fewer people can play volleyball.
    9. A pick-up can carry big weights. A lorry can carry bigger weights.
    10. A goat can produce two litres of milk. A cow can produce twenty litres of milk.

    Passive voice with modal verbs and superlatives
    Superlatives are comparisons among three or more items, places or things. In superlatives,
    we refer to what is most outstanding. On the other hand, we only compare two features
    or items in comparatives.

    Look at these examples:
    1. Food can be produced most cheaply in Kitabi.
    2. Rain received in Gicumbi might be the highest in the whole country.

    Rewrite the following sentences using superlatives. Each should be written in one
    sentence.
    1. More chickens than cows and sheep are found in Rwanda.
    2. Many factories are found in Gisenyi and Butare. These are fewer than those in Kigali.
    3. Many species of animals are found in Volcanoes National Park. Primates are more than the rest.
    4. Rains are received in July and September. More are received in March.
    5. Money can be made from cassava. More can
        be made from potatoes. A lot more can be made from flowers.
    6. Rwanda is visited by many business people. It is visited by foreign officials. It is visited
         by many more people as tourists.

    In groups of five, discuss and write down ten sentences that describe the physical features
    of our country. (Physical features include mountains, hills and valleys.) Use the passive
    voice to construct your sentences.

    Example is:
    Mount Karisimbi is admired by many tourists.
    Lake Kivu is big enough to be used to transport people.

    Comparatives and superlatives

    Comparing temperatures

    Read the following sentences.
    1. It is warmer in July than in October.
    2. In July it is warmer in Nyamagabe than in Kigali.

                 
    Draw this graph in your exercise book and indicate:
    1. Which months are hottest?                                                  3. Which month is the driest?
    2. Which month is the coldest?

    Comparing rainfall
    Study the graph below in groups.
          
    Answer the following questions:
    1. In which month does Kigali receive the highest amount of rain?
    2. In which month does Kigali receive the least amount of rain?
    3. Which is the wettest month?
    4. Which is the driest month?

    D. Writing

    So far, you have learnt how to plan and write a composition. You know how to make an
    outline by coming up with notes. At the same time, you know you have to check your work
    once you are through.

    We can study and make notes from a graph. For example, the graph below shows the
    temperature and rainfall in Kigali in a year. Study it in your groups and make notes about
    temperature and rainfall.
              
    1. Make notes on the temperature. Make use of comparatives and superlatives.
    2. Write a composition about temperature and rainfall in your locality.

    TEACHER: Your ideas are like gold.
    MAN: I knew it! You mean they are valuable?
    TEACHER: No, I mean they are rare.
