第4题
The United States government publishes guidelines for appropriate nutrient intakes. These are known as the Recommended Dietary Allowances (RDAs) and are updated regularly based on new research in nutrition. RDAs are suggested amounts of calories, protein, and some minerals and vitamins for an adequate diet. For other dietary substances, specific goals must await further research. However, for the U.S. population as a whole, increasing starch and fiber in ones diet and reducing calories (primarily from fats. sugar, and alcohol) is sensible. These suggestions are especially appropriate for people who have other factors for chronic diseases due to family history of obesity, premature heart disease, diabetes, high blood pressure, and high blood cholesterol, or for those who use tobacco. Snacks can furnish about one-fourth of the calorie requirements among teenagers. Those snacks should also provide much of the days allowances for protein, minerals, and vitamins. Sandwiches, fruit, and milk make good snacks for active teenagers. Food from the food pyramid may be part of any meal. A grilled cheese sandwich or a bowl of whole-grain cereal is just as nutritious in the morning as it is at noon. In addition, a good breakfast consists of any foods that supply about one-fourth of the necessary nutrients for the day. The passage directly states that most of the U.S. population should increase their intake of ______.
A protein B fats C starch and fiber D sandwiches
【正确答案】：C

第11题 The most popular organic gem is the pearl. A pearl is the response of a marine mollusk to the presence of an irritating impurity accidentally introduced into its body; a cultured pearl is the result of the intentional ion of a mother-of-pearl bead into a live mollusk. Whether introduced accidentally or intentionally, the pearl-making process is the same: the mollusk coats the irritant with a substance called nacre. Nacre is composed chiefly of calcium carbonate. Because very few natural pearls are now on the market, most pearls used in free jewelry are cultured. These include "Biwa" pearls and most other freshwater pearls. Cultured pearls are not easily distinguished from natural pearls except by an expert. Which of the following people could tell the difference between a cultured pearl and an organic pearl?
A Scuba diver. B Fisherman. C Jeweler. D Clerk.

第14题 Nacre is a substance that is ______.
A mechanically manufactured B the result of laboratory testing C organically secreted by the mollusk D present in the chemical composition of freshwater pounds
【正确答案】：C
【答案解析】 [分析] 推断题型。 文中第三句(Whether introduced accidentally or intentionally, the pearl-making process is the same: the mollusk coats the irritant with a substance called nacre.)说明无论是天然珍珠还是人工：养殖的珍珠，它们 的形成过程是一样的：贝类用一种被称之为珍珠质的物质将刺激性的杂物包裹 住。由此推断出珍珠质 nacre 是贝类 the mollusk 滋生分泌出的，所以选项 C 正确。
第15题 The main idea in this passage is that ______.
A most marketable pearls are cultured because nature does not produce enough of its own to satisfy the market B cultured pearls are of a higher quality than natural pearls
C there are two major methods of pearl-making D a natural "drought" of pearl production is taking place

CATTI三级笔译考试练习题及答案 2
At 51, Cathy McDonnell wanted to put her Oxford physics degree and former experience crunching data at Qinetiq to better use. She had worked part-time in a school for several years while her three children were young, but she wanted to get back into the corporate world.
Several applications later, all for jobs in her former field of defence, she was getting nowhere. Then a friend told her about “returnships”, a form of later-life work experience that some companies are experimenting with to help older people — mainly women — return to work, often after breaks to care for families.
Cathy eventually secured a place on an 11-week “Career Returners” programme with O2, open to men and women, which included being buddied with a 20-year-old male student who was also with the company on work experience. He helped to acquaint her with new technology, such as using an iPhone and accessing the company’s virtual private network from her laptop so she could work from home but still access internal files.
“On the assessment day, I thought they must have been looking at my project management skills. But they weren’t looking at us for specific roles. They were just thinking, ‘These women have a lot to offer, let’s see what they can do.’ That was refreshing.”
In fact, by hiring female returnees, companies can access hard skills these women developed in their former high-level jobs — and for a discount. In return, employers coach older females back into working life.Through her returnship, Ms McDonnell gained a full-time role as an operations data consultant, handling projects within service management at O2.She still is earning less than she would like to. “But it’s a foot in the door and the salary is up for review in six months,” she says.
It is still overwhelmingly women who stay home to care for young families. UK government figures show that women account for around 90 per cent of people on extended career breaks for caring reasons.
A lack of middle-aged women working, particularly in highly skilled roles, is costing the UK economy 50bn a year, according to a report. The report found that men over 50 took home nearly two-thirds of the total wages paid out to everyone in that age range in 2015. It blamed the pay gap on the low-skilled, part-time roles older women often accept. Some 41 per cent of women in work in the UK do so part-time, as opposed to only 11 per cent of men.
A study last year by economists found “robust evidence of age discrimination in hiring against older women” in a range of white and blue-collar jobs. The data show that it is harder for older women to find jobs than it is for older men regardless of whether they have taken a break from working.

【英译汉】：
In December 2019, a cluster of pneumonia cases were found. Scientists believe that It was caused by a previously unknown virus- Now named COV ID-19.
Coronaviruses have the appearance of a crown. Crown in Latin is called "corona" and thats how these viruses got their name. There are different types of coronaviruses that cause respiratory and sometimes gastrointestinal of symptoms.
Its known that coronaviruses circulate in a range of animals. But the animals which transmit C OVID-19 are not known yet. And the exact dynamics of how the virus is transmitted is yet to be determined.
From what is known so far, there can be a number of symptoms ranging from mild to severe. There can be fever and respiratory symptoms such as cough and shortness of breath. In more severe cases, theres been pneumonia, kidney failure and death. There is currently no specific medication for the virus and treatment is supportive care. There is currently no vaccine to protect against the virus. Treatment and vaccines are in development.
Nevertheless, we are committed to combatting the COVI D-19 epidemic. Its certainly troubling that so many people and countries have been affected, so quickly. Now that the virus has a foothold in so many countries, the threat of a pandemic has become very real. But it would be the first pandemic in history that could be controlled. The bottom line is: we are not at the mercy of this virus.
The great advantage we have is that the decisions we all make-as governments, businesses, communities, families and individuals can influence the trajectory of the epidemic. We need to remember that with decisive, early action, we can slow down the virus and prevent infections. Among those who are infected, most will recover.
Its also important to remember that looking only at the total number of reported cases and the total number of countries doesnt tell the full story. This is an uneven epidemic at the global level. Different countries are in different scenarios, requiring a tailored response. Its not about containment or mitigation. Its about both.
All countries must take a comprehensive blended strategy for controlling their epidemics and pushing this deadly virus back. Countries that continue finding and testing cases and tracing their contacts not only protect their own people, they can also affect what happens in other countries and globally. The WHO has consolidated its guidance for countries in four categories: those with no case; those with sporadic cases; those with clusters; and those with community transmission. For all countries, the aim is the same: stop transmission and prevent the spread of the virus.
For the first three categories, countries must focus on finding, testing, treating and isolating individual cases and following their contacts. In areas with community spread, testing every suspected case and tracing their contacts become more challenging. Action must be taken to prevent transmission at the community level to reduce the epidemic to manageable clusters.
【汉译英】
水稻是世界上最主要的粮食作物之一，世界上一半以上人口（包括中国 60%以上人口）都以稻米作为主食。中国是世界上最早种植水稻的国家，至今已有 7000 年左右的历史，当前水稻产量占全国粮食作物产量近一半。水稻作为主要的粮食，无论对中国还是对世界的重要性都是不言而喻的。中国在超级杂交水稻（super hybrid rice）生产方面成就突出，关键人物便是袁隆平。被誉为“中国杂交水稻之父”。他的名字不仅在中国家喻户晓，在国际上也享有盛誉。袁隆平于上世纪 60 年代开始杂交水稻研究。他带领科研团队使中国杂交水稻一直领先于世界水平，不仅不断实现杂交水稻的高产量目标，而且在生产实践中不断推广应用，从实际上解决了中国人吃饭难的问题。袁隆平还多次到美国、印度等国家传授技术，为 30 多个国家和地区的政府官员和科研工作者讲学，促进杂交水稻技术造福世界。
1987 年 11 月 3 日，联合国教科文组织在巴黎总部向袁隆平颁发科学奖，认为他的科研成果是“第二次绿色革命”。2004年，袁隆平获得世界粮食奖（the World Food Prize），表彰他为人类提供营养丰富、数量充足的粮食所做出的突出贡献。
