Sylhet Cadet College HSC Mock Test - 2020 Subject Code:

Time: 3 hours Subject: English 1st Paper Full marks: 100

Part–I : Reading (60 Marks) 1. Read the passage. Then answer the questions below.

When a girl gets married, she usually drops out of school and begins full-time work in her inlaws’ household. In the in-laws’ house, she is marginalized. She becomes vulnerable to all forms of abuse, including dowry-related violence. In Bangladesh, it is still common for a bride’s family to pay dowry, despite the practice being illegal. Dowry demands can also continue after the wedding. For an adolescent bride, even if her in-laws are supportive, there are greater health risks in terms of pregnancy and child birth. The majority of adolescent brides and their families are uninformed or insufficiently informed about reproductive health and contraception. The maternal mortality rate for adolescents is double the national rate. When adolescent girls are pulled out of school, either for marriage or work, they often lose their mobility, their friends and social status. The lack of mobility among adolescent girls also curtails their economic and non-formal educational opportunities. Moreover, they lack information about health issues. According to a study, only about three in five adolescents have even heard of HIV. It is also reported that more than 50 percent of adolescent girls are undernourished and suffer from anaemia. Adolescent fertility is also high in Bangladesh. The contribution of the adolescent fertility rate to the total fertility rate increased from 20.3% in 1993 to 24.4% in 2007. Moreover, neonatal mortality is another concern for younger mothers. While the situation for adolescent boys is somewhat better, many are vulnerable and lack the power to make decisions about their own lives. Many boys who are unable to go to school, or are unemployed, remain unaware of social or health issues. They are at considerable risk of being drawn into criminal activities. They are also more likely to get exposed to drugs and alcohol.

A. Choose the correct answer from the alternatives. 1X5=5

(a) The word 'uninformed' means ——. (i) gnostic (ii) unapprised (iii) unnamable (iv) hairy-heeled (b) What does the expression 'drop out of school' mean? (i) Inception of education in school (ii) Making the omega of education (iii) Becoming disquiet about school (iv) Adopting instruction in college instead of school (c) In their in-laws' house, many girls fall a victim to ——. (i) emancipation (ii) complacency (iii) maul (iv) better consumption (d) Which of the following statements is true? (i) Exchange of dowry is a part of licit marriage (ii) Dowry is an accredited practice in marriage (iii) Barter of dowry is not illegal (iv) Dowry is an unscriptural practice (e) Which of the following describes the maternal mortality rate best? (i) Aerial (ii) Moderate (iii) Meager (iv) Mediocre

B. Answer the following questions. 2X5=10

(a) From your reading of the passage, mention two consequences of early marriage of a girl. (b) How are the adolescent girls treated in her in-laws' house? (c) Why is the maternal mortality rate for adolescent so high? (d) What happens when an adolescent girl drops out of school? (e) How are the uneducated unemployed boys?

2. Read the following text and make a flow chart showing the activities of a real teacher.

(No. 1 has been done for you). 2X5=10 A most important truth, which we are apt to forget, is that a teacher can never truly teach unless he is still learning himself. A lamp can never light another lamp unless it continues to burn its own flame. The teacher who has come to the end of his subject, who has no living traffic with his knowledge, but merely repeats his lessons to his students, can only load their minds; he cannot quicken them. Truth not only must inform but inspire. If the inspiration dies out, and the information only accumulates, then truth loses its infinity. The greater part of our learning in the schools has been waste because, for most of our teachers, their subjects are like dead specimens of once living things, with which they have a learned acquaintance, but no communication of life and love. The educational institution, therefore, which I have in mind has primarily for its object the constant pursuit of truth, from which the imparting of truth naturally follows. It must not be a dead cage in which living minds are fed with food artificially prepared. It should be an open house, in which students and teachers are at one. They must live their complete life together, dominated by a common aspiration for truth and a need of sharing all the delights of culture. In former days the great master-craftsmen had students in their workshops where they co-operated in shaping things to perfection. That was the place

1 0 7

Page 2 of 3

where knowledge could become living – that knowledge which not only has its substance and law, but its atmosphere subtly informed by a creative personality. For intellectual knowledge also has its aspect of creative art, in which the man who explores truth expresses something which is human in him— his enthusiasm, his courage, his sacrifice, his honesty, and his skill. In merely academic teaching we find subjects, but not the man who pursues the subjects; therefore the vital part of education remains incomplete.

1. Learning himself to offer real teaching

→ 2. → 3. → 4. → 5. → 6.

3. Summarize the following text. 10 As a child you must have been told to greet your elders and visitors to your home according to your culture and tradition. You must also have been taught to be polite in company and keep quiet while others, especially your elders, spoke. Possibly, you at times grudged such schooling. Possibly, at times you even protested such disciplining. Now, certainly you know that you can’t always behave the way you want specially in the presence of others. There are rules of behaviour you have to follow in a company. We are social beings and have to consider the effect of our behaviour on others, even if we are at home and dealing with our family members. We have two terms to describe our social behaviour – ‘etiquette’ and ‘manners’. ‘Etiquette’ is a French word and it means the rules of correct behaviour in society. The word ‘manners’ means the behaviour that is considered to be polite in a particular society or culture. Manners can be good or bad. For example, it is a bad manner to speak with food in one’s mouth. No one likes a bad-mannered person. Remember that etiquette and manners vary from culture to culture and from society to society. We learn etiquette and manners from our parents, families and various institutions, such as schools, colleges or professional bodies. There are rules of behaviour for all kinds of social occasions and it is important to learn them and practise them in everyday life.

4. Read the following text and fill in the blanks with suitable words from the box. There

are more words than needed. Make any grammatical change if necessary. .5X10=5

Here many diaspora groups are working to achieve (j) —— impact and a stronger voice in matters that relate to their countries of origin.

5. Fill in the blanks with an appropriate word in each gap. 1X10=10

Because I have seen Bengal's face I will seek no more; The world has not anything more beautiful to show me. Waking up in darkness, gazing at the fig-tree, I behold Dawn's swallows roosting under huge umbrella-like leaves. I look around me And discover a leafy dome— Jam, Kanthal, Bat, Hijol and Aswatha trees — All in a hush, shadowing clumps of cactus and zedoary bushes. When long, long ago, Chand came in his honeycombed boat To a blue Hijal, Bat and Tamal shade near the Champa, he too sighted Bengal's incomparable beauty. One day alas. In the Ganguri, On a raft, as the waning moon sank on the river's sandbanks, Behula too saw countless aswaths bats besides golden rich fields And heard the thrush's soft song. One day, arriving in Amara, Where gods held court, when she danced like a desolate wagtail, Bengal's rivers, fields, flowers, wailed like strings of bells on her feet.
