Traits are characteristics you inherit from your parents; this means your parents pass some of their characteristics on to you through genes. For example, if both of your parents have green eyes, you might inherit the trait of green eyes from them. Or if your mom has freckles(雀斑), you might inherit that trait and wind up with a freckled face. And genes arent just in humans all animals and plants have genes, too. Genes hang out all lined up on thread-like things called chromosomes(染色体). Chromosomes come in pairs, and there are hundreds, sometimes thousands of genes in one chromosome. The chromosomes and genes are made of DNA, which is short for deoxyribo nucleic acid. Chromosomes are found inside cells, the very small units that make up all living things. A cell is so tiny that you can only see it through the lens of a strong microscope, and there are billions of cells in your body. Most cells have one nucleus. The nucleus, which is sort of egg-shaped, is like the brain of the cell. It tells every part of the cell what to do. How does the nucleus know so much? It contains our chromosomes and genes. Tiny as it is, the nucleus has more information in it than the biggest dictionary youve ever seen. 1. What does the underlined word “inherit” probably mean in the first paragraph? A. carry B. sendC. obtainD. pass2. Which of the following is NOT true according to the passage? A. The parents pass some characteristics on to their children. B. All living things receive traits from the old generations. C. Ones green eyes might be passed on from the parents. D. A mothers freckled face might affect her youngs face. 3. From the passage we can know that_. A. genes can decide all your characteristics from parentsB. genes exist inside cells that make up all living thingsC. genes tell every part of the cell what to doD. chromosomes come in pairs containing genes4. From the passage we can conclude that_. A. not all cells have one nucleus insideB. not all living things are made up of cellsC. genes arent in humans but in animals and plantsD. DNA is made of chromosomes and genes(B)2019南昌模拟Young women are more adventurous than young men when travelling abroad in gap years. One in three female backpackers visits more than three countries during a year out and travels alone, according to new research. By contrast, the majority of their male counterparts visit only one country and tend to travel in groups, says a survey by the Gap Year company, which provides information and services for students considering taking a year out. More women than men say that their prime reason for taking time off is to see the world and experience different cultures. Men were more likely to rank“having fun” higher on their list of preferences. Women were more likely to value the challenge of a foreign trip, and many cited reasons such as learning a language and meeting new people. The more adventurous gap years taken by women seem to work to their benefit; more than three quarters of those surveyed reported increased confidence, self-reliance and independence, whereas only half of the men had that experience. The research also showed that women were more likely to do voluntary work while travelling, with more than one in ten helping with teaching or development projects. One of the reasons given for this is a wish to see the country in an authentic light. A greater proportion(比例)of women than men faced objections or criticism from their families over their gap-year plans. Among the men surveyed, lack of money was the main barrier to travel. Carolyn Martin, a doctor from London, was a typically confident female traveller. Starting in Cape Town, she travelled around southern Africa and Australia with a string of unusual and sometimes dangerous jobs. “I had one job chasing elephants off the runway in Africa by banging a stick against a pan，” she recalled. “It was OK but one day I did get chased by one. ”She said that she had travelled alone because“you meet more people”5. By referring to “gap year”, the writer means _. Aa gap you come across after leaving high schoolBa time when you are caught in a dilemma between work and studyCa period before you find a job upon your graduation from collegeDa year off between high school and college for certain purposes6According to the article, _.

CThe article suggests that women travelling alone will have dangerous experiences. DMen students prefer to travel inside their own country rather than go abroad. 8Which of the following would be the best title of the article?
