中石器时代的

The first occupation occurred around 700,000 BP, and between then and 12,000 BP i.e. at the end of the last ice age and the beginning of the transition to the Mesolithic hominins were in Britain for only about 20% of the time.

第一个人类大约在70万年前，从那时起再往前推12万年之间---也就是在最后一次冰河时代和中石器时代的变迁之间---人类迁移至英国仅仅使用了这段时间的20%。

The religions of archaic cultures - the cultures of the Paleolithic, Mesolithic, and Neolithic ages - are also referred to as primitive.

宗教的古老文化-文化的旧石器时代，中石器时代和新石器时代的年龄-也被称为原始。

A small stone artifact, probably an arrowhead, with a blunt straight edge and a sharpened, crescent-shaped back, especially characteristic of the Mesolithic Age.

新月形石器一个小的石制的人工制造物，可能是个箭头，有钝的直边，尖的新月形背部，尤其是有中石器时代特点的

Within massive sandstone outcrops, above comparatively dense forest, are five clusters of natural rock shelters, displaying paintings that appear to date from the Mesolithic Period right through to the historical period.

在密林中大量沙石岩中，有五组天然石窟，里面岩画的历史从中石器时代一直延续到文明历史时代。

Of or relating to a middle period of the Stone Age.

属于或关于中石器时代的。

They do not want to change their stone age living conditions or move away from their jungle home.

他们不想改变他们石器时代的生活条件或是离开他们丛林中的家园。

The Tyrolean Iceman witnessed the Neolithic-Copper Age transition in Central Europe more than 5,000 years ago. His mummified corpse was recovered from an Alpine glacier on the Austro-Italian border in 1991. In 2000, scientists defrosted the Iceman's body for the first time and sampled DNA from his intestines.

提洛尔冰人是五千多年前中欧地区从新石器时代到铜器时代转变的证据，在1991年，人们在奥地利和意大利的边界处即阿尔卑斯冰川处发现了这具干尸，2000年，科学家第一次解冻了这具干尸并从他的肠中提取了样本DNA。

Results show that Pb enrichment factors varied from 1.0～1.8 in the cultural layers, and were not quite high. However, with the history going on from the Dawenkou Culture to the Longshan Culture, the Pb enrichment factor displayed an obvious rising trend, which indicated that the Pb in the cultural layers was probably associated with the development of metallurgic activities in the middle stage of the primitive society. From 5 050 cal a BP to 4 000 cal a BP, China underwent Stone Age, Chalcolithic Age and Bronze Age in sequence. Pb dust in the atmosphere increased with intensifying utilization of copper resources, which was probably the main cause of the rising enrichment factor in the cultural layers.

但是随着时间的推移，从大汶口文化到龙山文化，Pb的富集系数有明显逐步上升的趋势，表明遗址剖面中的Pb很可能与原始社会中期发展起来的冶金活动有关。5 050～4 000 cal a BP间，中国先后经历了石器时代、铜石并用时代，到最后进入青铜时代，这个过程中铜资源利用越来越多导致产生的大气粉尘铅越来越多，很可能是YC1剖面中Pb富集系数逐步增长的主要原因。

Making fire was among man's earliest achievements, and doubtless wood formed the earliest of fuels, first in caves, as remains of Stone Age hearths show, and later in mud and turf enclosures.

毫无疑问地，木材成为了最早的燃料。首先用在山洞中，正如石器时代的炉床所显示的，后来在泥和草地的封入物中也有发现。

Paintings from the Stone Age show early musical instruments.

从石器时代的画中我们可以见到早期乐器的模样。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
