Answers for Week 5

Dear all,

Here are the answers for Week 5.

Q1. (4)

Explanation: The keywords are "ambulance" and "scene of accident" which lead you to the answer of paramedics.

Do not overlook the importance of other subjects and world knowledge. It can be used as an item for English so read widely and learn more current affairs.

Q5. (1)

Explanation: The keywords are "no fire" and "false". In this phrasal verb, we always use false with alarm. False alarm states that something that was report turned out to be untrue.
You need to be exposed and constantly practise on phrasal verbs. They are important and specific.

Police frogman is a skilled underwater swimmer who wears a special suit of water-proof clothes/suit, a special apparatus on the head and back (oxygen cylinder) for breathing and a pair of large flat  plastic or rubber shoes (flippers), especially who works under water for under water military operations, police work.

Explanation: The keywords are "skills", "trapped miners" and "helped them stay alive". As a result, it is about the miners being able to survive. 
Durability comes from the root word "durable" and refers to how well or long an object can last and withstand wear and tear. (Also a term you need to know for SCIENCE)
Vitality refers to a person's energy and strength.

Questions for this week

Dear all,

Here are the questions for this week. I know it is a tiring weekend for you with Chingay but do take some time to complete and practise the questions.

English:

The focus is on vocabulary this week as it is identified as one of the section you really need a lot of improvement on. Exposing you to as much vocabulary words as possible will expose your words knowledge range. For those who have problems in remembering, remember to cover the answers and go through the paper once or twice or as many times as it helps you to remember.

Science

The topic is on respiratory system (P5 topic).

Answers will be out on Sunday or Monday. Happy revising!

Thank you,

answers for week 4

Dear all,

Here are the answers.

English Synthesis and transformation:

Q1. Gary asked Peta why he had to play soccer the following/next day.

Q2. Teddy told Ben that that hotel had been demolished thousand of years ago.

Q3. Peter asked if /whether they were still going for that workshop then.

Q4. Mary asked if/whether she had to be a Singapore citizen in order to qualify for that scholarship award.

Q5. Mother asked if/whether I was certain I had remembered to take out the clothes from the laundry the previous night.

Science

Q1. What do you think caused cell X to burst?

Topic: Cells
Concept: Animal and Plant cells have different parts and functions. Cell wall and chloroplast are not present in animal cells.

Answer: 
The Cell X absorbed more water than its cell membrane could hold or The cell does not have a cell wall to contain the water.

Explanation: The cell wall is an important part of the plant cell to hold the cell in place and protect the cell from the outside. The cell membrane of both cells are semi-permeable (only allows some items to pass in and out through the cell) and without a cell wall to hold the cell in place, cell X will burst when too much water is absorbed. On the other hand, the cell wall for Y protects the cell.

Q2.

Answer:
The cell wall of Cell Y supported the cell structure and was strong enough to prevent it from bursting.

Topic: Magnets

Concept: Magnetic objects can be magnetized by the stroking method. Like poles attract, unlike poles repel. A magnet has a North pole and a South pole on each opposite end.

Answer:

Part (A) i and ii
C: South Pole
D: North Pole

Part (B)

Both of the poles of steel bar XY would be like poles (South and South). A magnet has two unlike poles in which both the unlike poles of the magnet has the ability to attract and repel other magnets. In this instance, both the ends are like poles and it does not fulfil the characteristic of a magnet.

Topic: Heat (Expansion and Contraction)
Concept: Heat expands items, Cool air contracts items.

Answer: The metal bridge will crack and might collapse. The gaps allow for the metal structure to expand during a very hot day due to the heat and contract during a cool day. If there is no gaps for the metal structure to expand, it will be compressed and the structure will push against each other, resulting in a crack and collapse of the bridge.

Explanation: There are two parts to the answer. The first part is an observation of what happens to the bridge when there are no gaps on a very hot day. The second part involves the use of concepts and key words to explain the answer.

The gaps allow for expansion and contraction (not just expansion only) during hot and cool days. This gives space for the processes to take place. Without the gaps, the structure will push against each other and will crack.

Answers for week 3

Dear all,

Here are the answers for this week's questions.

Q6. (1) complete

Explanation: made (past tense) Susan (Noun) [if a verb is used here, it is used in the base form, meaning present tense and plural form]

Q7. (2) herself

Explanation: Keywords to highlight are "who completed the project". This is a tricky question. We are finding out who completed the project and in this case, it is Miss Chew, a female and hence the pronoun, 'herself'.

Q8. (4) were

Explanation: The rule for 'either...or' and 'neither...nor' questions is to always look at the second subject and in this case, it is his friends (plural). Now, let us take a look at the tense to use and the word 'rang' suggests that it is in the past tense thus, the answer should be in the plural form but past tense.

Q9. (3) does he

Explanation: The question is phrased in a questioning form, thus the two parts of the sentences should be opposite in meaning to each other. In this case, you must read very carefully. The first part 'hardly ever goes to parties' means that he does not usually go to parties so the second part of the sentence should be opposite of 'does not'.

Q10. (4) flown

Explanation: The keywords here are 'ever' and 'before' which would suggest that the perfect tense should be used as it has already taken place. 

Fly (present tense) Flew (past tense) Flown (perfect tense)

 Q16. (2) infested

Explanation: 

infested is used on insects or animals ; meaning to be present in large numbers to cause damage and harm

invasion is usually used on people, e.g invaded by enemies, invaded by the French army.

Q17. (4) fell through

Explanation: 

fell through means not completed and stopped

fell out means to have a disagreement and stop interacting with someone

Q18. (2) yields

Explanation: This question is of a higher difficulty level. The key word you have to look at is 'harvest'.

yield is to give forth or produce by a natural process or in return for cultivation. e.g This farm yields enough fruit to meet all our needs.

reaps is to get as a return, recompense, or result: to reap large profits.

Q19. (3) accessible

Explanation: The key words are "offshore islands" and "motorboat". As such, it is talking about travelling and whether the place itself is accessible.

Q20. (3) subsided

Explanation: The key word here is 'flood' and we often talk about a flood subsiding.

Subside means to sink to a low or lower level.

I realised I have forgotten to post the questions for this. I will do so tomorrow. My apologies.
