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.

资料：Large industrialized are now in a recession. What are the prospects for economic recovery?
The three most important industrial economies in the world are, at the moment, facing enormous problems. Germany is struggling with the cost of reunification and is in recession. Japan is also experiencing recession and the United States has a large budget deficit.
Forecasters and analysts face questions about the prospects of an economic recovery. Here are some of their findings:
The election of a new president of the United States gave hope to the rest of the world. If the US recovered, the rest of the world would face a more promising future. However, analysts now accept that the US will only recover very slowly.
Consumer and investor confidence is still lacking. Large deficits and declining short-term interest rates mean there is little scope for economic stimulus.
The Japanese economy, after years of trade and budget surpluses, is in deep recession and the growth rate has slowed down considerably. German economists have lowered their forecasts for economic growth this year. The lowering of German interest rates may bring some relief to other members of the European Exchange Rate Mechanism （ERM）. However, Germany's importance as Europe's largest export market may decline.
However, in some parts of the world, there are more positive signs, particularly in some Latin American countries in South-East Asia. Analysts says that, as long as the rate of interest stays above the rate of growth at national income, then the ratio of debt to income will get worse. Falling interest rates help towards overcoming this problem. They believe it may take several years before there is real recovery. However, advances in technology are offering hope for the world economy.

The tone of the passage suggest that the author is ______about the world economy.

A.doubtful
B.indifferent
C.positive
D.pessimistic
