点一下不认识的单词。

Matt Shaw is a scientist at the Jet Propulsion Laboratory in California. He works on special detectors called superconducting nanowire single photon detectors. These detectors can count single photons, which are tiny particles of light.

These detectors can see light from ultraviolet to far-infrared wavelengths. Infrared light is a type of light that people cannot see with their eyes. It is useful in many areas, such as astronomy, medicine, and space communication.

Scientists have made big progress in making cameras with many of these detectors. These cameras can take pictures by counting photons quickly and accurately. They also work with longer infrared light than before, up to 88 micrometers.

These new detectors will help scientists study space, medicine, and other areas. The team will continue to improve these cameras and detectors in the future.

难句解析

  1. 1

    These detectors can count single photons, which are tiny particles of light.

    逗号后面的 which 引导定语从句，解释前面的 single photons，意思是“这些单光子是很小的光粒子”。整句：这些探测器能计数单个光子，也就是非常微小的光粒子。

  2. 2

    Infrared light is a type of light that people cannot see with their eyes.

    that 引导定语从句，修饰前面的 light，意思是“人眼看不见的光”。整句：红外光是一种人眼无法看到的光。

  3. 3

    They also work with longer infrared light than before, up to 88 micrometers.

    work with 在这里不是“和……一起工作”，而是“能探测/适用于”。“longer infrared light than before”指“比以前更长波长的红外光”。整句：它们还能探测比以前更长波长的红外光，最长到88微米。

本篇语法

一般现在时 (Present simple)

一般现在时表示习惯、经常发生的事和事实：I drink tea every morning. 主语是 he / she / it 或单数名词时，动词要加 -s 或 -es：She works. He watches TV. 否定和疑问用 do / does：I don't like coffee. Does he live here?

I / you / we / they + verb · he / she / it + verb-s

故事中的例句

  • Matt Shaw is a scientist at the Jet Propulsion Laboratory in California.
  • These detectors can see light from ultraviolet to far-infrared wavelengths.
  • The team will continue to improve these cameras and detectors in the future.

常见错误

第三人称单数忘记加 -s（中文动词没有变化）。

She work in a bank.

She works in a bank.
