To attain this, it is necessary fo r the communicators o f radiation inform ation to be fam iliar w ith the laypeople’s perceptions o f these phenomena. A questionnaire survey was conducted to examine non-experts’ conceptions o f radiation phenomena. The survey revealed an incomplete understanding o f concepts such as radioactive decay, h a lf-life and absorption o f radia tio n and a lack o f differentiation o f between radiation and radioactive materials. Many respondents did not distinguish between sources o f ionising radiation and other environmental hazards. Nuclear power plants and submarines were the most feared sources o f radiation. There are indications that the lay understanding o f radiation phenomena and risk is to a large extent formed by mass media and that “school knowledge” o f these phenomena is not applied in situations belonging to the “real w orld”To resolve this problem, new teaching and inform ation procedures are needed. These should take into account the learners’ perceptions and should integrate “school knowledge”w ith considerations belonging to the “real w orld”.E n h a n c in g la n g u a g e a b ilityT A S K 21betrays, conception2 renders3exem plified, perception4 prevalent, secure5 prior to6 proportion, gloomy7 alternatives8 characterized, constitutes, hazard9 From the standpoint of, ranks10 external, a prerequisiteT A S K 31include: contain, embrace, encompass, comprise, be composed of, consist of2 valid: powerful, convincing, sensible, rational, viable, credible, plausible, weighty, well-founded,cogent, well-grounded3basic: underlying, fundamental, essential, root, prime, primary4 danger:hazard, risk, threat, menace, peril, jeopardize5 describe: depict, portray, characterize, narrate, outline, represent6 different: discrepant, contrary, conflicting, contradictory, inconsistent, incompatible,incongruous, various, diverse7 cause:prompt, move, inspire, stimulate, urge, spur, motivate, induce, evoke, instigate, impel8 c la rify: account for, ju stify, explain, illum inate, clear up, rationalize, elucidate ,explicate9highlight: emphasize, stress, accent, feature, underline, spotlight, accentuate, give prominence to, attach importance to, give priority to, underscore10 factor: component, item, element, ingredient, constituent, contributorD o in g re s e a rc h p ro je c tsT A S K 11Solvent, pesticide, smoke, viral aggressions, ultrave radiation and ionizing radiation.2 Cells could identify the DNA damage, and remove the damaged part and re-synthesis to repair theDNA.3 The Stochastic effects are not systematic to each person being exposed.

Students receiving linked instruction perform better in language courses than those not receiving such instruction (Kasper, 1997). They reap the benefits o f significantcontent-based second language success (Grabe & Stoller, 1997; 1997; S tryker & Leaver, 1997;gains in the second language, e.g., in the receptive skills o f listening and reading (Burger et al., 1997; Ready & Wesche, 1992) and in the productive skills o f w ritin g(Burger, 1989) and speaking (B urger &Chretien. 2001).They also achieve comparable or even better mastery o f d isciplinary content than ESL students or native English-speaking students not receiving content-based language instruction (Andrade &M akaafi, 2001; B abbitt, 2001; Kasper, 1994; W inter, 2004).The topic sentence is “content-based second language teaching promotes both language acquisition and academic success.”The w rite r uses literature evidence to support the idea in term s o f speaking, reading and w ritin g.Q u o tin gT A S K 11Author-focused version: According to Anyanwu (1983), most Nigerians believe that “urban existence is synonymous w ith extreme individual and community poverty”.Information-focused version: Influenced by western cultures，most Nigerians believe that “urbanexistence is synonymous w ith extreme individual and community poverty” (Anyanwu, 1883).2 Author-focused version: Anyanwu (1983) suggested that mothers should be educated “how to prepareand use hygienically acceptable supplementary foods”.Information-focused version: We may educate mother ““how to prepare and use hygienicallyacceptable supplementary foods” (Anyanwu, 1983).S u m m a riz in gT A S K 11 c. b. a. d2 b. a. c. d3 a. d. c. bT A S K 21Chinese big cities suffer from growing traffic problems.2 Some long and complicated sentences mean very little.3 The basic tenet o f constructivism holds that learners themselves construct knowledge, rather thanreceive it from outside.4 Some educationalists contend that deciding on a major is the most critical decision students facewhen entering college, whereas others argue that the most important thing fo r students to discover in university is their true interests, because many establish careers not related to the major they studied in college.5 The majority o f American Internet users, especially teenagers, use SNS, which has altered the paceand process o f making and maintaining friendships.6 According to Hirshi and Gottfredson, the propensity (倾向）o f someone to commit crime comesfrom his or her lack o f self-control, whereby the urge to feed desires causes one to even break the law.T A S K 31Gordon & Taylor (1989) believes that although most people feel a great deal o f anguish when faced w ith w riting tasks, this feeling can be managed by developing personal procrastination- avoidance strategy.2 Frick (1991) claims that history has demonstrated that technology affects education profoundly.Considering the definition o f technology broadly, one may say that prehistoric people usedprim itive technologies to teach skills to their young.3 Hewitt (1996) believes that acts o f academic dishonesty undermine the validity o f teaching andlearning.4 Edelso (2002) claims that legal rights and safeguards lead to investments by individuals, which hasa higher impact on raising living standards o f countries than these countries，natural resourceshave.。
