2019高考英语（九月）题型整合练（11）李仕才一、阅读理解。

ANowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有机体), which have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise where an organism is exposed to chemicals to create a nonspecific but stable change. For many people, the hightech production raises all kinds of environmental, ethical, health and safety problems. Particularly in countries with long farming traditions, the idea seems against nature.In fact, GM foods are already very much a part of our lives. They were first put on the market in 1996. A third of the corn and more than half the cotton grown in the U. S. last year was the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic genie is out of the bottle.However, like any new product entering the food chain, GM foods must be subjected to careful testing. In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs. In developing countries desperate to feed fastgrowing and underfed populations, the matter is simpler and much more urgent: do the benefits of biotech outweigh the risks?The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. The UN states that nearly 800 million people around the world are unhealthy. About 400 millionwomen of childbearing age don' t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values. Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to drought, poor soil and crop viruses.1.The passage mainly talks about________.A. the world's food problemB. the development in biotechC. the genetically modified foodsD. the way to solve food shortages2.According to the passage, GM foods________.A. will replace naturally grown foodsB. are far better than naturally grown foodsC. may help to solve the problem of poor nutritionD. can cause serious trouble in developing countries3.The underlined sentence “The genetic genie is out of the bottle.”in Paragraph 2 probablymeans that________.A.GM foods are available everywhereB. the technology in producing GM foods is advancedC. genetic technology may have uncontrollable powersD. genetic technology has come out of laboratories into markets4.What's the writer's attitude towards GM foods?A. Enthusiastic.B. Cautious.C. Disapproving.D. Unbelievable.【文章大意】本文是一篇说明文，主要介绍了转基因食品及其对人类生活的影响。

BWhat are your retirement plans? Keep working? Get more exercise? Or learn something new? You may put them on hold. There’s a chance that, sooner or later, you might have to move further than you were thinking, as far as Mars (火星)．On Thursday, National Geographic will show the first ever Mars show home, giving earthlings an idea of what their life could look like on the Red Planet. Set in the not­so­distant year of 2037, the igloo­shaped structure could be the home of your future.It shows a house built using recycled spacecraft parts and Martian soil, called regolith, which has been microwaved into bricks. Some partsof the home are recognisable—kitchen, bedroom—but there are fundamental differences that are vital for human survival.As the Martian atmosphere is around one hundredth as thick as the Earth’s, people will need permanent shelter from the sun and society will move largely indoors. Most buildings will be connected by underground passages and the houses won’t have windows. The homes will have simulated solar lighting, or natural light that has been bent several times.Walls will need to be 10 to 12 feet thick, to protect people from dangerous rays that can pass through six feet of steel, and a double air­locked entrance to keep the home under proper pressure.“We don’t think of our houses as things that keep us alive, but on Mars your house will be a survival centre，”says Stephen Petranek, author of How We’ll Live on Mars. This is not just the stuff of sci­fi. “Ten to twenty years from now there will certainly be people on Mars，”Petranek says.“We’ve had the technology for 30 years to land people on Mars, but we haven’t had the will，”Petranek says. “But two main factors have completely swung public attitudes.”The private companies’participation has forced government agencies to up their game, and influential films such as Gravity and The Martian have caught society’s eye.【解题导语】本文主要对人类未来在火星上居住作了相关介绍。
