11th grade. Unit 1. Lesson 4. How modals function (New Book)

Read the excerpts from the articles below and fi ll in the blanks with the words: 1. A new study of Chinese-American youth has found that family [blank_start]obligation[blank_end] plays a positive role in the mental health of teenagers. A greater sense of family obligation in the early teenage years could provide teenagers with strong family ties that make them feel secure even when they move through teenage years and become more independent. 2. Statistics say that youths raised by single parents have higher [blank_start]probability[blank_end] to perform poorly in school and take part in troublesome activities. Using the National Longitudinal Survey of Youth, we find that an additional 5 years with the biological father decreases the probability of smoking, drinking, drug addiction, and criminal behaviour by about 5.3%. 3. With a parent losing his job or getting her hours cut, money has to go to the [blank_start]necessity[blank_end] of life. For teens, [blank_start]necessities[blank_end] are not the gas bill or the education fee, it’s the latest version of Xbox or the newest iPhone. 4. Before I started writing this article, I had read many articles on the prevention of drinking, and most of them were based on [blank_start]prohibition[blank_end]. Such as “Ban drinking alcohol!” At the same time, prohibition is always an introduction to the conflict, and conflict with parents increases the risk of any form of addiction.
