Let’s talk about metal first Metal is very heavy And it is very hard and strong It usually feels cool if you touch it We use metal to make lots of things We use it (32) forks and knives We use it for keys We use it for cars We use it for these things because it is very strong
Next, let’s talk about glass Glass is very smooth It feels cool to touch It is not as heavy as metal It is hard But it is not strong It breaks very (33) ! Then why we use it? We use it because it is clear! You can see through glass! That’s why we use it for windows That’s also why we use it for glasses
Now, let’s talk about wood Wood is lighter than metal and glass It is not as strong as metal But it is much stronger than glass We use wood to make lots of things Things made from wood are usually light and hard and strong Chairs and tables are made from wood (34) are made from wood
Now let’s talk about cloth Cloth is very light It is much lighter than wood And it is very soft We use cloth to make lots of things For example, it is used to make clothing And it is used to make blankets
Last, let’s talk about plastic Plastic is also very light But it is different from cloth Sometimes it is soft And sometimes it is hard Plastic can be used to make thin plastic bags These are light, soft, and strong But plastic can also be used to make bicycle helmets These are light, hard, and strong A helmet and a bag seem different But they are (35) made from plastic

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 36 to 42
Six months ago I made a rash promise The leader of the youth club in our village rang me in March saying, “We’re thinking of running a children’s playscheme for a day in October half-term Would you be prepared to help?” My response was “Sure, why not?” In truth I was a little flattered to be asked, even though working as a care assistant with old people hardly qualified me for the role Still, I duly put the date in my diary and I forgot all about it I don’t know if you’ve noticed this but time has a habit of speeding along faster than a police car chasing a robber and, before I knew it, the day was dawning
I arrived at the youth centre that morning feeling full of trepidation There were 12 helpers including me and each pair had been allocated a particular age group Mine was the 10 to 11 year olds Even with the planning meeting I had attended the week before, I worried about whether I was up to the task Why hadn’t I read through the copious lesson plans we were given beforehand? And wasn’t the average 10-year-old more interested in the latest Play Station game than making things with paper and glue?
All too quickly the children began arriving The look of relief on parents’ faces as they handed their offspring over to us was quite comical A handful of the children were already members of the club but the other forty five or so were from the local primary schools Again I asked myself why I had elected to spend a day with all these ‘little monsters’ especially when I have two of my own to contend with!
I needn’t have worried as it turned out to be a marvelous day We watched entertaining DVD clips, learned ‘action’ songs, made clay pyramids, decorated biscuits, played memory games and spent some time in quiet reflection I say ‘we’ because I rediscovered my inner child and joined in all the activities
The particular highlight for me was the final rendition of “He’s got the whole world in his hands” in the closing part of the day The children knew the words and actions off by heart and sang so loudly it was almost enough to bring the roof down It’s difficult to explain those moments; only that the body tingles with the pleasure of having witnessed something so magical
Of course there were also moments of great poignancy I found it difficult to stop thinking of one little girl, who mentioned oh-so-casually that her mum was in hospital and would be there for a long time It’s easy for us adults to idealise childhood and forget that some children have their own burden of anxieties and concerns When I got home utterly exhausted, still with modeling clay under my fingernails, I reflected on what a privilege it had been
There was one disappointment for the children that the playscheme was only running for a day, and not the whole week As I said farewell to my group, one of the children turned and said “Can we it again in the next holiday, Miss?” My response was, “Sure, why not?”
Question 36: When the offer of the job was made the writer A felt she had made a mistake to agree
B thought she had appropriate experience for the job C believed she shouldn't have been asked
D gave the impression she wasn't sure about accepting the job Question 37: When the day arrived the writer was surprised
A that the day had come round so quickly B because she'd forgotten to write down the date C because she witnessed a car chase on the way D that she woke up at dawn
Question 38: When the writer arrived to start her job she A put the children into pairs
B realised she should have done more preparation C felt confident she could deal with 10 and 11 year olds
D saw the children had brought their own electronic games to play with Question 39: According to the writer, the parents were

(4)Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50
PHOTOSYNTHESIS
Almost all living things ultimately get their energy from the sun In a process called photosynthesis, plants, algae, and some other organisms capture the sun's energy and use it to make simple sugars such as glucose Most other organisms use these organic molecules as a source of energy Organic materials contain a tremendous amount of energy As food, they fuel our bodies and those of most other creatures In such forms as oil, gas, and coal, they heat our homes, run our factories and power our cars
Photosynthesis begins when solar energy is absorbed by chemicals called photosynthetic pigments that are contained within an organism The most common photosynthetic pigment is chlorophyll The bright green color characteristic of plants is caused by it Most algae have additional pigments that may mask the green chlorophyll Because of these pigments, algae may be not only green but brown, red, blue or even black
In a series of enzyme-controlled reactions, the solar energy captured by chlorophyll and other pigments is used to make simple sugars, with carbon dioxide and water as the raw materials Carbon dioxide is one of very few carbon-containing molecules not considered to be organic compounds Photosynthesis then converts carbon from an inorganic to an organic form This is called carbon fixation In this process, the solar energy that was absorbed by chlorophyll is stored as chemical energy in the form of simple sugars like glucose The glucose is then used to make other organic compounds In addition, photosynthesis produces oxygen gas All the oxygen gas on earth, both in the atmosphere we breathe and in the ocean, was produced by photosynthetic organisms Photosynthesis constantly replenishes the earth's oxygen supply
Organisms that are capable of photosynthesis can obtain all the energy they need from sunlight and not need to eat They are called autotrophs Plants are the most familiar autotrophs on land In the ocean, algae and bacteria are the most important autotrophs Many organisms cannot produce their own food and must obtain energy by eating organic matter These are called heterotrophs
Question 43: What can be inferred about algae?
A Green algae are less common than other colors of algae B Algae are photosynthetic organisms
C They are ineffective producers of sugars
D They are chemically different from other plants
Question 44: The word “fuel” in the first paragraph is similar in meaning to
A give fuel to B provide nutrients for
C help to function D produce organic materials
Question 45: The word “pigments” in the second paragraph is closest in meaning to
A colours B chemicals C organisms D characteristics
Question 46: The phrase “this process” in the third paragraph refers to the process of
A photosynthesis B carbon fixation
C absorbing solar energy D storing chemical energy
Question 47: It can be inferred from the passage that the author considers solar energy to be A essential for every organism on earth
B a perfect solution to the energy problem C a permanent and everlasting source of energy D useless to most bacteria and algae
Question 48: The word “replenishes” in the third paragraph is closest in meaning to
A refines B renews C refills D regulates
Question 49: Which of the following is NOT true?
A Plants capture the sun's energy to make sugars B Organic materials contain an amount of energy C Photosynthesis produces oxygen gas
D Plants are familiar heterotrophs
Question 50: From the passage, we can see that A Most plants have additional pigments B Oxygen helps the process of photosynthesis C Algae are a kind of simple plants
D Autotrophs obtain energy by eating organic matter
