to call into question the truth of … (韦氏)
If you doubt whether something is true or possible, you believe that it is probably not true or possible(柯林斯)
e.g.He doubts everyone’s word. 他不相信任何人的话。
regarded or deserving to be regarded with suspicion(韦氏)
You use suspect when you are stating something that you believe is probably true, in order to make it sound less strong or direct. (柯林斯)
e.g.He suspected that the woman staying in the flat above was using heroin. 他怀疑住在楼上公寓里的女人在吸毒。
Archaeologists studying Bonito phase (ca. A.D. 900-1140) Native American ceramics from Chaco Canyon, New Mexico, observed that many pots had beenaltered after firing to revise their decorative designs--usually,intricate geometric patterns painted in black on white slipped surfaces. In some cases, a new design was imposed over an earlier one; less often, the original design was simply covered with white slip. Crown and Wills doubt that the alterations were made to correct design errors. Many Chacopots with design errors were left unaltered. Furthermore, when errors were corrected, revisions were made prior to firing—either by painting directly over the error or by scraping off designs and applying new slip and paint, which is a less time-consuming method than repainting and refiring flawed pots.

Although some skeptics points to Arctic places such as the high latitudes of Greenland, where temperatures seem to have fallen, a recent scientific report concludes that in recent decades average temperatures have increased faster in the Arctic than else where.Scientists have long suspected that several factors lead to greater temperature swings at Earthspolar regions than elsewhere. First, most of the Arctic is covered in snow and ice, which are highly reflective; if snow and ice melt, the exposed soil, which absorbs heat, serves to accelerate warming.Second, the polar atmosphere is thin, so little energy is required to warm it. Third, less solar energy is lost in evaporation at the frigid poles than in the tropics.
