A pessimist is someone whose first thought is that things will go badly. Before a picnic they see rain; before a test they see a low mark.

A pessimist悲觀的人 is someone whose first thought is that things will go badly是那種第一個念頭就想到「事情大概會不順利」的人。Before a picnic they see rain野餐前他們會先想到下雨；before a test they see a low mark考試前他們會先想到低分。

It names a habit of mind, not one worried hour — if you feel dark only today, people will not call you a pessimist.

It names a habit of mind這個字講的是一種思考習慣，not one worried hour而不是某一個小時的擔心——if you feel dark only today如果你只是今天心情比較灰暗，people will not call you a pessimist大家不會因此就叫你悲觀的人。

As a label for a whole person it is a little heavy, so friends more often say you are being negative, or that you always look on the dark side. People also use it lightly: “I’m a pessimist about the trains” just means they do not trust them to be on time.

As a label for a whole person把它拿來當成整個人的標籤，it is a little heavy有點太重了，so friends more often say you are being negative所以朋友比較常會說你在negative（負面），or that you always look on the dark side或是說你老是往壞處想。People also use it lightly人們也會輕鬆地用它："I'm a pessimist about the trains""I'm a pessimist about the trains"（我對火車很悲觀） just means they do not trust them to be on time只是說他們不相信火車會準時而已。

The opposite kind of person is an optimist. Calling someone a pessimist can sound like a complaint, so it is kinder when you talk about a mood than when you pin it on a person.

The opposite kind of person is an optimist相反的那種人是optimist（樂觀的人）。Calling someone a pessimist把某人叫做pessimist can sound like a complaint聽起來可能像在抱怨，so it is kinder when you talk about a mood than when you pin it on a person所以講一時的心情，會比把標籤釘在一個人身上來得溫和一點。
