length简单

Whichever approach, the key is to determine your length of focus time and stick to it.

无论采用哪种方法，关键都在于确定你专注时间的长度并坚持下去。

The peer-reviewed results showed that the target group of pupils drew on a wider vocabulary, used words “classed as more sophisticated or rarer”, and wrote at greater length.

经同行评审的结果显示，实验组学生使用的词汇更广，用了“被归为更高级或更罕见”的词，而且写得更长。

A children’s author and poet who had become a keen amateur photographer, Peters watched the butterflies and idly wondered if he could capture them in flight. It swiftly became an obsession as he recovered from a successful operation to remove the cancer. In recent summers, he has travelled the length and breadth of Britain to photograph all 58 native species of butterfly. Now the fruits of those summers have been published in a beautiful new book.

彼得斯是一位儿童作家和诗人，后来成了一名热心的业余摄影师。他看着那些蝴蝶，随意地想自己能否拍下它们飞行的样子。在成功切除癌症的手术后康复期间，这个念头很快变成了一种痴迷。最近几个夏天，他走遍英国各地，拍摄了全部58种本土蝴蝶。如今，这几个夏天的成果已汇编成一本精美的新书出版。

Throughout the trip, Jackson juggled multiple cameras and plate sizes using the “collodion process” that required him to coat the plates with a chemical mixture, then expose them and develop the resulting images with a portable darkroom. The crude technique required educated guesses on exposure times, and involved heavy, awkward equipment — several men had to assist in its transportation. Despite these challenges, Jackson captured dozens of striking photos, ranging from majestic images like his now-famous snapshot of Old Faithful, to casual portraits of expedition members at the camp. While veterans of previous expeditions wrote at length about stunning trail sights, these vivid photographs were another thing entirely.

在整个旅途中，杰克逊使用“火棉胶工艺”同时摆弄多台相机和多种尺寸的底片，这种工艺要求他先给底片涂上一层化学混合物，然后曝光，再用便携式暗室冲洗出影像。这种简陋的技术需要凭经验推测曝光时间，而且所用设备笨重难使——需要好几个人协助搬运。尽管困难重重，杰克逊还是拍下了几十张引人注目的照片，从他那张如今已闻名于世的老忠实泉快照这样的壮丽画面，到营地里考察队员的随意肖像，不一而足。以往考察的老手们曾长篇累牍地描写沿途的壮丽景色，而这些生动的照片则完全是另一回事。
