问题     As humankind moves into the third millennium, it can rightfully
claim to have broken a new ground in its age-old quest to master the 【M1】______
environment. The fantastic achievements of modern technology and
the speed at which scientific discoveries are translating into 【M2】______
technological applications attest to the triumph of human endeavor.
At the same time, consequently, some of these applications threaten 【M3】______
to unleash forces over which we have no control. In other word, the 【M4】______
new technology Man now believes allows him to dominate this wider 【M5】______
cosmos could well be a Frankenstein monster waiting to turn off its 【M6】______
master.
    This is an entirely new situation that promises to change many
of the perceptions governing life on the planet. The most acute
challenges facing with the future are likely to be not only those 【M7】______
pitting man against his fellow man, but those involving humankind’s
struggle to preserve the environment and ensure the sustainability of
life on earth. A conflict waged to ensure the survive of the human 【M8】______
species bound to bring humans closer together. Technological 【M9】______
progress has thus proved to be a double-edged sword, giving rise to a
new form of conflict: a clash between Man and Nature. The new
conflict is more dangerous than the traditional one between man and
his fellow man, which the protagonists at least shared a common 【M10】______
language. But when it comes to the reactions of the ecosystems to the
onslaught of modern technology, there is no common language.
【M3】

选项

答案consequently—however

解析 逻辑错误。文章开头说明了人类的伟大科技进步,这里提出有些科技成果会对人类造成威胁,与前文是转折关系,鉴于其在句中的位置,用表转折关系的副词however。
