A．升高温度

B．将CH₃OH(g)从体系中分离

C．充入He，使体系总压强增大

D．再充入1mol CO和3mol H₂④为了寻找合成甲醇的温度和压强的适宜条件，某同学设计三组实验，部分实验条件已经填在下面实验设计表中。

根据短文内容判断下列句子的正误，正确的用“A”，错误的用“B”。    

     It's good to get along with your teacher because it makes school time more pleasant. Kids who get

along with their teachers can learn more. They're also more comfortable asking questions. This makes it

easier to do your best on tests. When you get along with the teacher,    he or she can help you solve

(解决) your problems and help you do well at school.

     Being a kid in middle school is a great time in your life.  You are learnig many interesting things and

you are thinking in new ways. Your teacher knows that and wants to help you. You should remember

that teachers want to help you. That's why they wanted to be teachers in the first place-to teach!

     Some kids are always good students, whether they like the teacher or not, but most kids are sensitive

to the way they get along with the teacher. However, even if (即使) you don't really like your teacher,

you should try to ask questions and get to know him or her better.

( )1. Kids may not feel good if they don't get along well with teachers.

( )2.  Teachers will give kids better grades if kids get along well with them.

(     )3. You learn the most interesting things when you're in middle school.

(     )4. According to the passage, all kids like their teachers.

(     )5. The writer thinks that kids should get along well with their teachers.
