第2题：
The food we eat seems to have profound effects on our health.Although science has made enormous steps in making food more fit to eat ,it has, at the same time,made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is nto a new discovery. In 1945, about 35 years ago, government researchers realized that nitrates, commonly used to preserve color in meats,and other food additives,caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this ,penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures, the practices continue.
The word 'carcinogenic' most nearly means '___'.a.trouble-making
b.color-retaining
c.money-making
d.cancer-causing答案：D解析： -
第3题：
Text 1 A new study suggests that contrary to most surveys,people are actually more stressed at home than at work.Researchers measured people’s cortisol,which is a stress marker,while they were at work and while they were at home and found it higher at what is supposed to be a place of refuge.“Further contradicting conventional wisdom,we found that women as well as men have lower levels of stress at work than at home”,writes one of the researchers,Sarah Damske.In fact women even say they feel better at work,she notes.“It is men,not women,who report being happier at home than at work.”Another surprise is that findings hold true for both those with children and without,but more so for nonparents.This is why people who work outside the home have better health.What the study doesn’t measure is whether people are still doing work when they’re at home,whether it is household work or work brought home from the office.For many men,the end of the workday is a time to kick back.For women who stay home,they never get to leave the office.And for women who work outside the home,they often are playing catch-up-with-household tasks.With the blurring of roles,and the fact that the home front lags well behind the workplace in making adjustments for working women,it’s not surprising that women are more stressed at home.But it’s not just a gender thing.At work,people pretty much know what they’re supposed to be doing:working,making money,doing the tasks they have to do in order to draw an income.The bargain is very pure:Employee puts in hours of physical or mental labor and employee draws out life-sustaining moola.On the home front,however,people have no such clarity.Rare is the household in which the division of labor is so clinically and methodically laid out.There are a lot of tasks to be done,there are inadequate rewards for most of them.Your home colleagues—your family—have no clear rewards for their labor;they need to be talked into it,or if they’re teenagers,threatened with complete removal of all electronic devices.Plus,they’re your family.You cannot fire your family.You never really get to go home from home.So it’s not surprising that people are more stressed at home.Not only are the tasks apparently infinite,the co-workers are much harder to motivate.
According to Damaske,who are likely to be the happiest at home?A.Working mothers.
B.Childless husbands.
C.Childless wives.
D.Working fathers.答案：B解析：细节题【命题思路】这是一道细节题。主要考查考生准确理解题干，精准定位，并能正确掌握定位信息，辨别干扰选项的能力。【直击答案】根据题干关键信息“Damaske”定位到第二段第三、四句，即Damaske的观点。这两句提到“It is men，not women,who report being happier at home than at work…，but more so for nonparents.”，即“研究发现是男人，而不是女人，在家比在工作中更高兴。更令人吃惊的是，这种情况对有无孩子都一样，尤其是对于没有孩子的人。”综合对比，确定B为最佳答案。【干扰排除】A、C项两项均为反向干扰，原文说的是男人比女人在家更快乐，故排除。根据该句“but more so for nonparents”可知D项错误，原文是没有孩子的男性，并非工作中的父亲。 -
第4题：
资料：Economic performance is improving in most of the world's leading economies but is still short of a self-sustaining upswing, the Organization for Economic Cooperation and Development said on Wednesday.
In an update to its economic forecasts, the Paris-based international organisation representing advanced economies said that more private sector investment was needed for the expansion to endure, for wages to rise sustainability and for inequalities to be tackled.
Although all leading economies are now recording positive growth, Catherine Mann, the OECD's chief economist, urged governments to “curb your enthusiasm [ because] strong and sustained medium-term global growth is not yet secured”.
The OECD's economic outlook shows upgrades to the 2017 growth forecasts in China, Russia and Europe excluding the UK with the world outlook also appearing stronger in 2018.
World growth should rise from a low of 3.1 per cent in 2016, to 3.5 per cent this year and 3.7 per cent in 2018, the OECD forecast, with the US, the Eurozone, Brazil and Russia contributing most to the improved global outlook.
China's predicted growth rate of 6.8 per cent in 2017 and 6.6 per cent in 2018 has been revised higher by 0.2 percentage points in both years and although India's growth rate has been revised down, reflecting adjustment to its new goods and services tax, it is likely to remain the fastest growing large economy in the world.
Only the UK, which remains embroiled in Brexit negotiations, has a deteriorating outlook. Responding to the OECD's forecast that the British economy will be the slowest growing in the Group of Seven in 2018 having been near the top of the league table in 2016, the British Treasury said it was not complacent.
What is the best title for the passage？A.The prosperity of the leading economies
B.The engine of the world economy
C.China，the trail blazer of the world economy
D.Global economy improving but lacks self-sustaining upswing答案：D解析：本题考查主旨大意。

第13题：
The Sahara【撒哈拉沙漠】
The name Sahara derives from the Arabic word for “desert” or “steppe”. At 3. 5 million square miles, an area roughly the size of the United States, the Sahara Desert in northern Africa is the largest desert in the world. It spans the continent from the Atlantic Ocean to the Red Sea. Daytime temperatures can reach as high as 130°F. The humidity sometimes gets into the teens. But it can also be as low as 2.5 percent, the lowest in the world. Most of the Sahara receives less than five inches of rain per year, while large areas sometimes have no rainfall at all for years.
At the heart of the Sahara is the landlocked north African country of Niger. Here the sand dunes can be 100 feet tall and several miles long. Here sand plains stretch over an area larger than Germany where there is neither water nor towns. Yet sitting in the midst of the surrounding desert is the town of Bilma. Suddenly there are pools of clear water. Surprisingly, there are groves of date palms. Underground water resources, or oases, sufficient to support irrigated agriculture are found in dry stream beds and depressions. Irrigation ditches run off a creek to water fields. Corn, cassava, tea, peanuts, hot peppers, and orange, lime, and grapefruit trees grow in these fields. Donkeys and goats graze on green grass.
The Sahara of Niger is still a region where you can see a camel caravan of 500 camels tied together in loose lines as long as a mile, traveling toward such oasis towns. There a caravan will collect life-sustaining salt, which is mined from watery basins, and transport it up to 400 miles back to settlements on the edges of the desert. The round trip across the vast sands takes one month.
文章(36~40)
This passage is mostly about________.A) life in the Sahara B) the deserts of Africa
C) BilmaD) how camels travel in the desert答案：A解析： -

The OECD’s economic outlook shows upgrades to the 2017 growth forecasts in China, Russia and Europe excluding the UK with the world outlook also appearing stronger in 2018.经合组织在经济展望中，上调了对中国、俄罗斯和欧洲（除英国外）2017年的增长预测，2018年的全球经济前景似乎也更加强劲。
